Database design online , capable of generating CRUD code

“I can’t imagine life without it. It saves so much time, greatly increases my work speed, and relieves existing stress!” — From a developer’s voice.

Choosing the right database design online tool can be a bit confusing because there are so many options. This cost-free choice of online database structure design tool, softfactory, will start a new chapter for you.

How to create a database table structure?

Customize the construction of database table structure Manually create tables, design field indexes, foreign keys, and you can redefine the structure, forms, and their relationships according to your preferences. Import table You can import file types in the following formats: DDL, PDManer, PowerDesigner. AI create table You can convert natural language into My SQL, Oracle, etc. If no type is selected, My SQL is the default.

What is the relationship between primary keys and unique identifiers?

Every table must have a primary key, which is indispensable because it guarantees the uniqueness of each row in the table. In addition, the primary key is also used to establish relationships with other tables in the database. Without a primary key, there is no reliable way for a table to identify individual records. This may lead to data integrity problems, query accuracy issues, and difficulties in updating the table. If a table in the schema does not have a primary key, there is a risk that the table contains duplicate rows, which will lead to incorrect query results and application errors. On the other hand, primary keys can make it easier to interpret data models. By looking at the primary keys of each table in the entity relationship diagram, programmers writing queries will know how to access each table and how to join it with other tables.

Why did you build this?

We built softfactory internally to facilitate anyone interested in database structure design. It allows them to have an experience even if they have no experience, saving time and bringing convenience for a wide range of database developers.

Who do you recommend it to?

It can run on a PC web page, making it suitable for existing database developers and all beginners without experience. Its tables and AI-generated codes can be planned infinitely, with the broadest appeal.

Prof explained the server structure for my DB apps course yesterday. The classes all operate on a single Oracle 11g server, and each user account is created as its own schema with like 200mb of memory or something just to do whatever they want with for the whole course

Worth noting considering the triggers were using dont have permissions to access the server globally. Like 6 different people in my section were running around trying to figure out how to create a new schema within their memory allowance, but that seemed a little too stupid to be the answer. Lo and behold, common sense prevailed and the default target schema is always wherever the trigger was created

Structured Query Language

What is SQL?

SQL stands for Structured Query Language, and it is a standard programming language for managing relational databases. It is used to create, modify, and query databases, as well as to manage and control access to the data stored in them. SQL is used by database administrators, developers, and analysts to work with data and automate data-related tasks. SQL allows users to interact with databases by defining and manipulating data structures, running queries, and performing other data-related tasks. SQL is widely used in the industry, and it is supported by many relational database management systems such as MySQL, Oracle, Microsoft SQL Server, and PostgreSQL. It includes three major sub-languages:

DATA DEFINITION LANGUAGE

DATA DEFINITION LANGUAGE (DDL) is a language used to define and manage the database schema or structure. DDL commands are used to create, modify, or delete database objects such as tables, views, indexes, or constraints. Examples of DDL commands are CREATE, ALTER, and DROP.

INTERACTIVE DATA MANIPULATION LANGUAGE

INTERACTIVE DATA MANIPULATION LANGUAGE (IDML) is a language used to manipulate or query data stored in a database. IDML commands are used to insert, retrieve, update, or delete data from a database. Examples of IDML commands are SELECT, INSERT, UPDATE, and DELETE.

EMBEDDED DATA MANIPULATION LANGUAGE

EMBEDDED DATA MANIPULATION LANGUAGE (EDML) is a programming language used to embed IDML commands into procedural programming code. EDML allows developers to manipulate data stored in a database using programming code written in languages such as C++, Java, or Python. Examples of EDML statements are SQL statements embedded in a C++ program to retrieve data from a database, or an SQL statement embedded in a Java program to insert data into a database.

For example, if the join condition is partment_id=partment_id, then rows that do not satisfy this condition are not returned.Īn outer join returns all rows that satisfy the join condition and also returns rows from one table for which no rows from the other table satisfy the condition. The optimizer determines the order in which the database joins tables based on the join conditions, indexes, and any available statistics for the tables.Īn inner join is a join of two or more tables that returns only rows that satisfy the join condition. The database combines pairs of rows, each containing one row from each table, for which the join condition evaluates to TRUE. Most joins have at least one join condition, either in the FROM clause or in the WHERE clause, that compares two columns, each from a different table. Unlike DDL statements, DML statements do not implicitly commit the current transaction.ĭescription of "Figure 7-1 Projection and Selection" For example, a transaction to transfer money could involve three discrete operations: decreasing the savings account balance, increasing the checking account balance, and recording the transfer in an account history table. UPDATE employees SET salary=9100 WHERE employee_id=1234 ĭELETE FROM employees WHERE employee_id=1234 Ī collection of DML statements that forms a logical unit of work is called a transaction. INSERT INTO employees (employee_id, last_name, email, job_id, hire_date, salary)

Oracle sqleditor update#

The example uses DML to insert a row into employees, update this row, and then delete it: SELECT * FROM employees The following example uses DML to query the employees table. Lock a table or view, temporarily limiting access by other users ( LOCK TABLE). View the execution plan for a SQL statement ( EXPLAIN PLAN). Remove rows from tables or views ( DELETE). Update or insert rows conditionally into a table or view ( MERGE). Retrieve or fetch data from one or more tables or views ( SELECT).Īdd new rows of data into a table or view ( INSERT) by specifying a list of column values or using a subquery to select and manipulate existing data.Ĭhange column values in existing rows of a table or view ( UPDATE). For example, ALTER TABLE changes the structure of a table, whereas INSERT adds one or more rows to the table.ĭML statements are the most frequently used SQL statements and enable you to: Whereas DDL statements change the structure of the database, DML statements query or change the contents. In either case, the two INSERT statements have already been committed.ĭata manipulation language ( DML) statements query or manipulate data in existing schema objects. If the ALTER TABLE statement succeeds, then the database commits this statement otherwise, the database rolls back this statement. In the preceding example, two INSERT statements are followed by an ALTER TABLE statement, so the database commits the two INSERT statements. INSERT INTO plants VALUES (2, 'Amaryllis') # DML statementĪn implicit COMMIT occurs immediately before the database executes a DDL statement and a COMMIT or ROLLBACK occurs immediately afterward. INSERT INTO plants VALUES (1, 'African Violet') # DML statement The example then uses DDL to alter the table structure, grant and revoke read privileges on this table to a user, and then drop the table. The following example uses DDL statements to create the plants table and then uses DML to insert two rows in the table. Oracle Database also supports techniques that you can use to make the optimizer perform its job better. The application does not need to process the rows one by one, nor does the developer need to know how the rows are physically stored or retrieved.Īll SQL statements use the optimizer, a component of the database that determines the most efficient means of accessing the requested data. The database can pass these rows as a unit to the user, to another SQL statement, or to an application. The database retrieves all rows satisfying the WHERE condition, also called the predicate, in a single step. For example, the following statement queries records for employees whose last name begins with K: SELECT last_name, first_name You need be concerned with implementation details only when you manipulate the data. SQL enables you to work with data at the logical level. The SQL language compiler performs the work of generating a procedure to navigate the database and perform the desired task.

Oracle sqleditor how to#

SQL is declarative in the sense that users specify the result that they want, not how to derive it. There are two broad families of computer languages: declarative languages that are nonprocedural and describe what should be done, and procedural languages such as C++ and Java that describe how things should be done.

MariaDB is a commonly used OpenSource database mainly known for being robust and scalable with new storage engines. MariaDB is a development of MySQL which puts focus on stability and performance and to make it free to users. It is the default database in most Linux distribution. With a variety of tools and plugins, MariaDB is widely applicable. In this guide, we are going to look at how to install MariaDB 10.6 on CentOS 7 | CentOS 8 Features of MariaDB 10.6 MariaDB 10.6 is the current stable version of MariaDB and comes with a number of new features as discussed below: Ignored Indexes – These are indexes that are visible and maintained but not used by the optimizer sys schema supported- This is a “system” database containing views and procedures for investigating performance problems. SKIP LOCKED – Locked tables are skipped from being updated or selected. JSON_TABLE() – can create a JSON table that can be used as a subquery from a JSON document. OFFSET…FETCH…[WITH TIES] – WITH TIES is an optional clause that adds extra functionality. Example as used Oracle compatibility – There are ongoing works in making MariaDB compatible with OracleDB with some Oracle Syntaxes and functions already added. The Improvements in MariaDB 10.6 from MariaDB 10.5 include: Atomic DDL – CREATE, ALTER, DROP and RENAME are atomic and crash safe. If MariaDB server crashes while processing any of these operations, the change will either e done completely or not done at all. InnoDB improvements – First insert to an empty table is faster. Also writes to temporary tables are avoided.Faster implicit and explicit temporary tables. Improvements in Galera. Ability to enable encrypted connections between two nodes without downtime. Also added flags to specify if galera controversial compatible features should be enabled. Clean up to remove unsupported features such as TukoDB Engine, Cassandra Engine, some InnoDB variables and some innodb_checksum_algorithm. Step 1: Update System Packages Ensure that you are running the latest system packages before installation to avoid possible inconveniences with dependencies. sudo dnf upgrade Step 2: Add MariaDB Repository We need to create a MariaDB repo file and add the content for MariaDB installation curl -LsS -O https://downloads.mariadb.com/MariaDB/mariadb_repo_setup sudo bash mariadb_repo_setup --mariadb-server-version=10.6 Command execution output: [info] Checking for script prerequisites.

Using Ora2Pg to Migrate Data from Oracle to openGauss

Introduction to Ora2Pg

Ora2Pg is an open-source tool for migrating data from Oracle to PostgreSQL. By connecting to Oracle, Ora2Pg automatically scans and extracts object structures and data, generates SQL scripts, and applies the scripts to PostgreSQL manually or automatically.

Official website: https://ora2pg.darold.net/

Advantages of Ora2Pg

Supports exporting most types of database objects, including tables, views, sequences, indexes, foreign keys, constraints, functions, stored procedures, and others.

Automatically converts the PL/SQL syntax to the PL/pgSQL syntax, avoiding manual modification to some extent.

Generates migration reports, containing migration difficulty evaluation and person-day estimation.

Compresses exported data to reduce disk overhead as required.

Provides various configuration items, allowing you to customize migration operations.

Application of Ora2Pg in openGauss

The main language of Ora2Pg is Perl. It uses the Perl DBI module and connects to the target PostgreSQL database by using DBD: Pg. openGauss is compatible with PostgreSQL communication protocols and most syntaxes. As such, you only need to modify some names. Ora2Pg can also be used in openGauss.

Usage Example of Ora2Pg

Ora2Pg exports DDL statements of object structures to SQL files. Table data can be exported to files by running the INSERT or COPY statement or be directly imported to the target database without generating intermediate SQL files.

Ora2Pg provides the ora2pg command to complete these processes. Generally, multiple commands need to be executed for one migration. Ora2Pg provides a more convenient method to obtain the export and import scripts and the migration directory template by creating a migration project. The scripts integrate several ora2pg commands and the psql command (gsql for openGauss) required for importing SQL files. You only need to run the two scripts to complete the migration. The demonstration in this document uses the scripts.

Installing Dependencies

The language of Ora2Pg is Perl. Therefore, you need to install the required Perl module.

# Perform the following operations as the root user: yum install -y perl-ExtUtils-CBuilder perl-ExtUtils-MakeMaker yum install perl-CPAN

Install DBI, DBD:Pg, DBD:Oracle on which Ora2Pg depends to connect to the database.

perl -MCPAN -e 'install DBI' perl -MCPAN -e 'install DBD:Pg'

Install Oracle Instant Client or Oracle on the local host before installing DBD:Oracle.

# Download Oracle Instant Client from the Oracle official website and install it. rpm -ivh oracle-instantclient12.2-basic-12.2.0.1.0-1.x86_64.rpm rpm -ivh oracle-instantclient12.2-devel-12.2.0.1.0-1.x86_64.rpm rpm -ivh oracle-instantclient12.2-jdbc-12.2.0.1.0-1.x86_64.rpm rpm -ivh oracle-instantclient12.2-sqlplus-12.2.0.1.0-1.x86_64.rpm # Set the environment variable ORACLE_HOME. export ORACLE_HOME=/usr/lib/oracle/11.2/client64 # Set ORACLE_HOME as follows if Oracle has been installed on the local host: export ORACLE_HOME=/opt/oracle/product/19c/dbhome_1 export LD_LIBRARY_PATH=$ORACLE_HOME/lib # Install DBD:Oracle. perl -MCPAN -e 'install DBD:Oracle'

Installing Ora2Pg and Creating a Migration Project

# Go to the code directory. <you_install_dir> is the target installation path. perl Makefile.PL PREFIX=<your_install_dir> make && make install # Set environment variables and check whether the installation is successful. <source_code_dir> is the path for downloading the code. export PERL5LIB=<source_code_dir>/lib export PATH=$PATH:<your_install_dir>/usr/local/bin ora2pg –help # Create a migration project. ora2pg --init_project oramig

After a migration project is created, the oramig directory template is generated in the current directory, as shown in the following figure. The directory template contains the export_schema.sh and import_all.sh scripts, which are used for subsequent data export and import. The schema and sources directories store DDL statements of each object. The schema directory stores statements after the PL/SQL syntax is converted into the PL/pgSQL syntax, while the sources directory stores PL/SQL statements before conversion. The data directory stores table data files, the config directory contains the ora2pg.conf configuration file, and the reports directory stores migration reports.

./oramig/ schema/ dblinks/ directories/ functions/ grants/ mviews/ packages/ partitions/ procedures/ sequences/ synonyms/ tables/ tablespaces/ triggers/ types/ views/ sources/ functions/ mviews/ packages/ partitions/ procedures/ triggers/ types/ views/ data/ config/ reports/

Now, you can run the ora2pg command. The following lists some command-line parameters that can be specified when you run the ora2pg command. These parameters can be set in the ora2pg.conf file. When you specify a configuration file, the values of the command-line parameters overwrite the corresponding values in the configuration file.

Usage: ora2pg [-dhpqv --estimate_cost --dump_as_html] [--option value] -a | --allow str: Specifies the list of objects that can be exported. The objects are separated by commas (,). -b | --basedir dir: Specifies the default export directory for storing exported SQL files. -c | --conf file: Specifies the path of the configuration file. -e | --exclude str: Specifies the list of objects that are excluded from the export. The objects are separated by commas (,). -i | --input file: Specifies the SQL file to be imported. You do not need to connect to Oracle when importing the file. -o | --out file: Specifies the path for storing the exported SQL file. The default value is the output.sql file in the current directory. -p | --plsql: Enables the conversion from PL/SQL code to PL/pgSQL code. -s | --source DSN: Specifies the data source of Oracle DBI. -t | --type export: Specifies the export type. This parameter will overwrite the export type (specified by TYPE) in the configuration file. -u | --user name: Specifies the username for connecting to Oracle. You can also use the ORA2PG_USER environment variable. -w | --password pwd: Specifies the user password for connecting to Oracle. You can also use the ORA2PG_PASSWD environment variable. --init_project NAME: Initializes a typical Ora2Pg project and generates a directory template. --view_as_table str: Exports views as tables. Use commas (,) to separate multiple views.

Configuring Ora2Pg

The ora2pg.conf file contains all configuration items, which can be used to customize migration operations. The following describes some common configuration items.

ORACLE_HOME: Specifies the environment variable ORACLE_HOME. The DBD:Oracle module uses this variable to search for the required Oracle database. The setting method is involved in dependency installation.

ORACLE_DSN: Specifies the data source name in the standard DBI DSN form. For example:

ORACLE_DSN dbi:Oracle:host=oradb_host.myhost.com;sid=DB_SID;port=1521

or

ORACLE_DSN dbi:Oracle:DB_SID

For the second method, you need to declare the system identifier (SID) in the $ORACLE_HOME/network/admin/tnsnames.ora file or the tnsnames.ora file in the directory specified by the environment variable TNS_ADMIN.

ORACLE_USER and ORACLE_PWD: Define the username and password for connecting to Oracle, respectively. Note that if possible, log in as the Oracle super administrator to avoid permission issues and ensure that nothing is missing.

PG_DSN: Specifies the name of the target database. The following uses openGauss as an example. The database to be connected is mydb with the IP address localhost and the port number 5432.

PG_DSN dbi:Pg:dbname=mydb;host=localhost;port=5432

PG_USER and PG_PWD: Specify the username and password for connecting to the target database, respectively. Note that the user must have the permission to remotely connect to openGauss as well as read and write permissions on the corresponding database. Specifically, the host where Ora2Pg runs and the user must be in the remote access whitelist of openGauss.

SCHEMA: Specifies the schema to be exported. As shown in the following, the objects associated to the APPS schema are extracted.

SCHEMA APPS

ORA_INITIAL_COMMAND: Sends an initial command to Oracle after the connection. For example, disable an access control policy before reading an object or set some session parameters.

TYPE: Specifies the type of the objects to be exported, including tables, views, sequences, indexes, foreign keys, constraints, functions, stored procedures, and others. The default value is TABLE. As shown in the following, ordinary tables and views are exported.

TYPE TABLE VIEW

For more details about the configuration items, visit the official website at the following link:

https://ora2pg.darold.net/documentation.html

Test the connection. After configuring the DSN of Oracle, run the following command to test the database connection:

ora2pg -t SHOW_VERSION -c config/ora2pg.conf

The version of Oracle will be displayed by running the preceding command.

Running Migration Scripts

The configuration is as follows. Connect to the target database as the system user.

ORACLE_HOME /opt/oracle/product/19c/dbhome_1 ORACLE_DSN dbi:Oracle:host=127.0.0.1;sid=ORCLCDB;port=1521 ORACLE_USER system ORACLE_PWD manager SCHEMA testuser PG_DSN dbi:Pg:dbname=mydb;host=127.0.0.1;port=5432 PG_USER testuser PG_PWD openGauss123

Modify the export type of export_schema.sh. In this migration, tables and functions are exported.

Run the export script and wait until the migration is complete. A DDL file of the corresponding type is generated in the schema and source subdirectories, and the command for exporting table data is provided at the end.

sh export_schema.sh

In addition, a migration report in HTML format is generated in the reports directory.

Before running the import script, perform the following operations:

Create a database in openGauss, create a user in the database, and set the owner of mydb to the user. (In import_all.sh, createuser and createdb of PostgreSQL are used to create users and databases.)

Create the environment variable in the bin directory of openGauss, so that the client tool gsql can be used.

Change psql in import_all.sh to gsql.

Add an option for executing the script when data is imported by a common user, and specify the user password to avoid frequent password input.

Run the import script. In the script, the testuser user is used to log in to the mydb database with the IP address 127.0.0.1 and the port number 5432. The -f option indicates that the check on whether the user and database need to be created is skipped.

sh import_all.sh -d mydb -o testuser –h 127.0.0.1 -p 5432 –f 1

After the script is executed, the system prompts you whether to import the object structures and data, as shown in the following figure. (In the preceding information, the -w option is added by manually modifying the import_all.sh script.)

For table indexes and constraints, you can import them after data is imported.

Log in to openGauss to view the migration result.

Disadvantages of Ora2Pg

Ora2Pg uses regular expressions and adopts text replacement to convert the PL/SQL syntax to the PL/pgSQL syntax. However, for design reasons, Ora2Pg supports only conversion of some syntaxes.

DDL statements are generated by concatenating character strings. However, this method does not fully support some syntaxes, such as the syntax for creating partitioned tables.

Migrate Your SQL Server Database to Amazon RDS

Amazon RDS is a web service that provides cloud database functionality for developers looking for a cost-effective and simple way to manage databases. If you’re looking to migrate your existing SQL database to RDS, this is the guide for you. RDS offers six database engines: 1. Amazon Aurora 2. Microsoft SQL Server 3. Oracle 4. PostgreSQL 5. MYSQL 6. MariaDB With RDS, there is no need for you to buy any other rack and stack hardware or install any software.The complexity of moving your existing Microsoft SQL Server to Amazon RDS is mostly determined by the size of your database and the types of database objects which you are transferring. For example, migrating a database which has data sets on the order of gigabytes along with stored triggers and procedures is going to be more complex than migrating a modest database with only few megabytes of test data and no stored procedures or triggers. Why You Might Consider Migrating Your SQL Database to Amazon RDS RDS allows developers to set up database instances in the cloud. Developers are relieved of the complexity of managing and maintenance of the database. Instead, they can focus on developing successful products. There’s one issue, however: There is no file system access. Though this is usually not a huge problem, it becomes a concern if you are trying to restore or create an SQL Server backup (.bak) file. This may sound like a daunting task, but it is in fact quite easy. In this post, we have tried to provide you with some easy steps to migrate your SQL Server database to Amazon RDS: 1. The first step would be to take a snapshot of the source RDS instance. 2. Secondly, you will have to disable automatic backups on the origin RDS instance. 3. Now, create your target database by disabling all foreign key constraints and triggers. 4. Import all the logins into the destination database. 5. The next step is creating the schema DDL with the help of the Generate and Publish Scripts Wizard in SSMS. 6. Next, execute the SQL commands on your target DBA to create your schema. 7. You can use either the bulk copy command (cp) or the Import/Export Wizard in SSMS to migrate your data from the origin database to your target database. Migrate Your SQL Server Database to Amazon RDS 8. Clean up the target database by re-enabling the foreign key constraints and triggers. 9. Again re-enable the automatic backups on the source RDS instance. Thankfully, after experimenting with this process many times, we found a better solution not documented in the AWS documentation. SQL Azure Migration Wizard To save time and avoid errors, we have discovered a new and better solution called the SQL Azure Migration Wizard. With SQL Azure Migration Wizard, the process of migrating databases (or anything including views/tablse/stored procedures) in, out, or between RDS instances is much easier and faster. To migrate your SQL database to Amazon RDS using SQL Azure Migration Wizard, follow these easy steps. Step1: Download the SQLAzureMW Tool Download SQL Azure Migration Wizard on CodePlex. Next, you need to extract the SQLAzureMW.exe file. You can utilize SQL Server Management Studio for connecting your local SQL server and Amazon Web Service RDS instance. But, before doing all this, make sure that you have a good connection to these two servers. Step 2: Begin the Migration Double click on the SQLAzureMW.exe file. A page will appear on your screen and what you now need to do is to select Database as an option under the Analyze/Migrate category. Once you do this, click on the Next button. Step 3: Source Database Tasks Now enter your Source SQL Server Database connection details and click on the Connect button. Choose the source database and click on the button that says ‘Next.’ Then select an option named as ‘Script all database objects’.This option can enable to do the complete migration of the database. But if you don’t want to migrate entire database then you select an option that says ‘Select specific database objects.’ Step 4: Create Scripts Create scripts for all selected SQL server objects. You should save the script on local hard drive and the move ahead by hitting a click on a button ‘Next’. Step 5: Destination Database Process Now you have created a script of your database. You will now be required to enter your RDS SQL Server connection credentials and then connect it. Step 6: Select the Target Database Choose the target database that you would like to migrate. If you have not created any database earlier, then create a new one using Create Database option and go next. Be sure to do a quick check to confirm if there are any errors. Step 7: The Grand Finale You can now verify your SQL Server Management Studio and check all the migrated data. As you can see, SQL Azure Migration Wizard saves a lot of time. You will have to modify settings in your corporate firewall if your database is on-premises. In case your database is already hosted on Amazon Web Services, you can also add an entry to your instance’s security group. Next, what you have to do is simple: launch and prepare an Amazon RDS instance running SQL. Then restore the database from the SQL dump and take note of the current log file name. Now you will use the database dump to start the RDS instance. Once the RDS instance is initialized, you will be required to run the replication stored procedures that are supplied as part of the release to configure the RDS instance. Once your RDS instance matches any changes that have taken place, the application configuration can be modified to use it in preference to the existing version. Summary Thus sums up the process on how to migrate a SQL Server database to Amazon RDS. The process of data migration is not a very complicated process but a very easy one indeed. We hope that this post was useful enough in helping all those who want to migrate their SQL Server Database to Amazon RDS.

Dbeaver Mysql Client

DBeaver Overview

DBeaver is a free, open source multiplatform database management tool and SQL client for developers and database administrators. DBeaver can be used to access any database or cloud application that has an ODBC or JDBC driver, such as Oracle, SQL Server, MySQl, Salesforce, or MailChimp. Devart DBeaver provides you with the most important features you'd need when working with a database in a GUI tool, such as:

SQL queries execution

Metadata browsing and editing

SQL scripts management

Data export/import

Data backup

DDL generation

ER diagrams rendering

Test data generation

BLOB/CLOB support

Database objects browsing

Scrollable resultsets

The tool comes in two editions — Community and Enterprise. Enterprise Edition supports NoSQL databases, such as MongoDB or Cassandra, persistent query manager database, SSH tunneling, vector graphics (SVG) and a few other enterprise-level features. Note though that you can access a MongoDB database from DBeaver Community Edition using the respective Devart ODBC driver. For the purposes of this guide, we'll use the Community Edition of DBeaver to retrieve data from Oracle via the Open Database Connectivity driver.

Creating an ODBC Data Source to Use Oracle Data in DBeaver

Click the Start menu and select Control Panel.

Select Administrative Tools, then click ODBC Data Sources.

Click on the System DSN tab if you want to set up a DSN name for all users of the system or select User DSN to configure DSN only for your account.

Click the Add button and double-click Devart ODBC Driver for Oracle in the list.

Give a name to your data source and set up the connection parameters.

Click the Test Connection button to verify that you have properly configured the DSN.

When using ODBC driver for Oracle with DBeaver, SQL_WVARCHAR data types may be displayed incorrectly in DBeaver. To prevent this, you need to set the string data types to Ansi either in the Advanced Settings tab of the driver configuration dialog or directly in the connection string (String Types=Ansi) — all string types will be returned as SQL_CHAR, SQL_VARCHAR and SQL_LONGVARCHAR.

Connecting to Oracle Data from DBeaver via ODBC Driver for Oracle

Follow the steps below to establish a connection to Oracle in DBeaver.

DBeaver SQL Client for OpenEdge. Progress does not have a SQL Client like Microsoft has SQL Server Management Studio or MySQL has Workbench. DBeaver is an excellent SQL Client for OpenEdge using JDBC. This article discusses how to configure DBeaver to connect to OpenEdge using JDBC and execute SQL statements. Install DBeaver. DBeaver is a free, universal SQL client that can connect to numerous types of databases—one of which is MySQL. I want to show you how to install and use DBeaver to connect to your remote MySQL server. First copy mysql.exe and mysqldump.exe into the dbeaver folder. Or you change the Local Client the location in the c0onnection wizard. Improve this answer. Follow edited Sep 7 '20 at 16:54. Answered Sep 7 '20 at 16:36. 19.1k 4 4 gold badges 19 19 silver badges 34 34 bronze badges.

In the Database menu, select New Database Connection.

In the Connect to database wizard, select ODBC and click Next.

Enter the previously configured DSN in the Database/Schema field.

Click Test Connection. If everything goes well, you'll see the Success message.

This article shows how to connect to MySQL data with wizards in DBeaver and browse data in the DBeaver GUI. Create a JDBC Data Source for MySQL Data. Follow the steps below to load the driver JAR in DBeaver. Open the DBeaver application and, in the Databases menu, select the Driver Manager option. Click New to open the Create New Driver form.

Serge-rider commented on Feb 28, 2017 Some MySQL UI clients may have builtin mysqldump, mysqlrestore, mysql.exe + set of libraries of some particular MySQL client version. But DBeaver definitely not one of such clients. On Windows you can install MySQL Workbench (it includes all command line tools).

Viewing Oracle Database Objects and Querying Data

Dbeaver Mysql Client_plugin_auth Is Required

You can expand out the database structure in DBeaver's Database Navigator to visualize all the tables in Oracle database. To view and edit the data in a table, you need to right-click on the target table name and select View data.The content of the table will be displayed in the main workspace.

Dbeaver Mysql Native Client

If you want to write a custom SQL query that will include only the necessary columns from the table, you can select New SQL Editor in the SQL Editor main menu. Create your query and run it by clicking Execute SQL Statement to view the results in the same window.

How to migrate your data from the MySQL Database Service (MDS) to MDS High Availability

On March 31st, 2021, MySQL introduced a new MySQL Database Service (MDS) option named MDS High Availability (MDS H/A). “The High Availability option enables applications to meet higher uptime requirements and zero data loss tolerance. When you select the High Availability option, a MySQL DB System with three instances is provisioned across different availability or fault domains. The data is replicated among the instances using a Paxos-based consensus protocol implemented by the MySQL Group Replication technology. Your application connects to a single endpoint to read and write data to the database. In case of failure, the MySQL Database Service will automatically failover within minutes to a secondary instance without data loss and without requiring to reconfigure the application. See the documentation to learn more about MySQL Database Service High Availability.” From: MySQL Database Service with High Availability If you already have data in a MDS instance and you want to use the new MDS H/A option, you will need to move your data from your MDS instance to a new MDS H/A instance. This is a fairly easy process, but it will take some time depending upon the size of your data. First, connect to the MDS instance via an OCI (Oracle Cloud Infrastructure) compute instance. Login to your compute instance: ssh -i opc@Public_IP_Address If you don’t have MySQL Shell installed, here are the instructions. Execute these commands from your compute instance: (answer “y” or “yes” to each prompt) Note: I am not going to show the entire output from each command. sudo yum install –y mysql80-community-release-el7-3.noarch.rpm sudo yum install –y mysql-shell Connect to the MySQL Shell, using the IP address of your MDS instance. You will need to enter the user name and password for the MDS instance user. mysqlsh -uadmin -p -h Change to the JavaScript mode with /js (if you aren’t already in JavaScript mode): shell-sql>/js You can dump individual tables, or the entire instance at once. Check the manual for importing data into MDS for more information. The online manual page – Instance Dump Utility, Schema Dump Utility, and Table Dump Utility – will provide you with more details on the various options. For this example, I am going to dump the entire instance at once, into a file named “database.dump“. Note: The suffix of the file doesn’t matter. shell-js>util.dumpInstance("database.dump", { }) You will see output similar to this (which has been truncated): Acquiring global read lock Global read lock acquired Gathering information - done All transactions have been started Locking instance for backup Global read lock has been released Checking for compatibility with MySQL Database Service 8.0.23 ... Schemas dumped: 28 Tables dumped: 264 Uncompressed data size: 456.56 MB Compressed data size: 365.24 MB Compression ratio: 5.4 Rows written: 47273 Bytes written: 557.10 KB Average uncompressed throughput: 3.03 MB/s Average compressed throughput: 557.10 KB/s Quit the MySQL Shell with the “q” command. I can check the dump file: [opc@mds-client ~]$ ls -l total 760 drwxr-x---. 2 opc opc 365562813 Mar 31 19:07 database.dump Connect to the new MDS H/A instance. ssh -i opc@Public_IP_Address Start MySQL Shell again: mysqlsh -uadmin -p -h You will use the MySQL Shell Dump Loading Utility to load the data. For more information – see the Dump Loading Utility manual page. You can do a dry run is to check that there will be no issues when the dump files are loaded from a local directory into the connected MySQL instance: (Note: the output is truncated) util.loadDump("database.dump", {dryRun: true}) Loading DDL and Data from 'database.dump' using 4 threads. Opening dump... dryRun enabled, no changes will be made. .... No data loaded. 0 warnings were reported during the load. There are many options for loading your data. Here, I am going to just load the entire dump file. If you have problems, you can use the Table Export Utility and export individual tables. You might want to export and import larger tables on their own. I only need to specify my dump file, and the number of threads I want to use. (Note: the output is truncated) util.loadDump("database.dump", { threads: 8 }) Loading DDL and Data from 'database.dump' using 8 threads. Opening dump... Target is MySQL 8.0.23-u2-cloud (MySQL Database Service). Dump was produced from MySQL 8.0.23-u2-cloud Checking for pre-existing objects... Executing common preamble SQL ... 0 warnings were reported during the load. After the data has been loaded, you will want to double-check the databases and tables in the MDS H/A instance, as well as their sizes, by comparing them to the MDS instance. That’s it. Moving your data from a MDS instance to a MDS H/A instance is fairly easy. Note: You will need to change the IP address of your application to point to the new MDS H/A instance.
