5 Types of SQL Commands You Must Know

It is very important for a user embedded with SQL in database management to have a full-fledged interaction with the database so that the actual work gets done smoothly. Knowing the 5 Types of SQL Commands You Must Know ensures effective data handling, whether you are an amateur developer or an expert. TCCI-Tririd Computer Coaching Institute is one of the leading institutes where expert training and guidance are provided in SQL and Database Management.

These are the five types of SQL commands that one needs to know:

1. Data Definition Language (DDL)- Definition of Database Structure

DDL commands are concerned with defining and changing the structure of the database. Applying these commands has a direct impact on the schema of a database.

CREATE - Used to create tables, databases, index, or views.

ALTER - Modification of an existing database object, which may include the addition of new columns to a table.

DROP- Deletes tables, databases, or other database objects permanently.

TRUNCATE- Deletes all records from a table but keeps the structure for future use.

2. Data Manipulation Language (DML)- Manipulating Data

DML commands allow users to act on the data stored in a database. Retrieval and modification of the data are the primary operations performed by these commands.

INSERT - Inserts new records into a table.

UPDATE - Updates existing records in a table.

DELETE - Deletes a few records from a table.

3. Data Query Language (DQL)- Retrieving Data

The main purpose of DQL is to fetch data from the database.

SELECT - Feeds data from one or many tables based on the stipulated conditions.

4. Data Control Language (DCL)- Controlling Access To Data

DCL commands are meant for the control of users accessing the database.

GRANT - A specific privilege is assigned to users or roles.

REVOKE - Removes previously granted privileges.

5. Transaction Control Language (TCL)- Controlling Transaction

TCL commands are used for the efficient and secure execution of database transactions.

COMMIT- Saves all transaction changes.

ROLLBACK- Undo changes if an error occurs.

SAVEPOINT- Creates intermediate points in a transaction.

Conclusion

If you are someone looking to work with databases, then mastering these five sorts of SQL commands is necessary. To help you understand database management comprehensively, TCCI-Tririd Computer Coaching Institute offers an elaborative SQL training program. Our well-trained instructors guide both beginners and advanced students through practical and real-life applications.
