Utilization and Performance Evaluation of HierarchyId in SQL Server

In the intricate world of database management, navigating through hierarchical data like organizational charts or product categories poses a significant challenge. SQL Server steps up with the HierarchyId data type, a nifty CLR (Common Language Runtime) feature, tailor-made for those looking to streamline the storage and querying of hierarchical information. We’re about to take a deep dive into…

As far as the other functions are concerned, it is worth mentioning that the library supports a vast array of SQL-specific features, including but not limited to transparent application failover, tabled-valued parameters, file stream, notification. Moreover, it supports queuing and reliable messaging or user-defined types, such as geography, geometry or HierarchyID,…

SQL Server Compact Toolbox 3.7.2–Visual Guide of new features

After more than 260.000 downloads, version 3.7.2 of my SQL Server Compact Toolbox extension for Visual Studio 2013, 2012 and 2010 is now available for download. This blog post is a visual guide to the new features included in this release, many suggested by users of the tool via the CodePlex issue tracker. The focus for this release is a number of features that help improve the experience when using the new support for SQL Server Compact 3.5 (supplied by yours truly) in Entity Framework 6.1 and the related Entity Framework 6.1 Tools. Run “Generate from Model” script without errors When using the “Generate Database from Model” option in the Entity Data Model Tools, the tool generates a script to DROP and CREATE the generated objects in the database. If you have tried to run the script until now in the SQL Server Compact Toolbox, the script would fail. A new option “Ignore DDL errors” in the Toolbox SQL Editor will allow you to run the script without any errors: DDEX install requires VS restart The simple DDEX providers supplied by the Toolbox for VS 2012 and VS 2013 are installed when the Toolbox is activated, and therefore require VS to be restarted to be used. A notification is now available to notify you of this. You can read more about the DDEX providers in my previous blog post here and here. (Also, notice the new, “modern” icons in the toolbar of the Toolbox.) Preserve SQL Server date types A new option is now available to control scripting of the SQL Server date, datetime2 and datetimeoffset data types. The default behaviour is to always convert these column types to datetime (SQL Server Compact does not have these datatypes). But this can cause data loss (as datetime has limited precision) or overflow errors, as datetime only supports dates from 1753 to 9999, unlike date, datetime2 and datetimeoffset, that all support dates from 0001 to 9999. Improved About dialog The About dialog has been improved for readability, and contains a counter for the current number of Toolbox downloads: Bug fixes EDMX generation feature failed if only VS 2012 and not VS 2013 was installed. "Refresh" of tables, including refresh after schema changes, was broken Scripting API improvements - improved SQLCE runtime check - datetimeoffset columns scripted as datetime by default now, not nvarchar() - sql_variant and hierarchyid handling improved, to avoid getting wrong ordinal for identity and timestamp - sqlite indexes are now always given unique names The scripting API improvements are also included in the latest version of my SQL Compact command line export tool and Scripting API, available here. Feedback As usual, please provide feedback if you have any feature requests, ideas or encounter any issues (or even bugs!!) by using the CodePlex Issue tracker.

SQL Server Compact & SQLite Toolbox 4.4 & 4.5 – Visual Guide of new features

After more than 470.000 downloads, version 4.5 of my SQL Server Compact & SQLite Toolbox extension for Visual Studio 2010 and later is now available for download and available via Tools/Extensions and Updates in Visual Studio. This blog post is a visual guide to the new features, improvements and bug fixes included in this release, many suggested by users of the tool via the GitHub issue tracker I have moved the source code and issue tracker to GitHub, and I am planning to move the remaining CodePlex content “soon”. I have also moved the source of the scripting API that the Toolbox uses extensively to the same GitHub repository. As always, and suggestion, bug reports and pull requests are welcome!

New icons

The icons of the extension have all been overhauled, and updated to use the latest VS 2015 icons/images. From users already trying out the latest bits, I have received positive feedback on this visual change.

Query editor toolbar redesign and more

I have also started using Azure AppInsights to track (anonymously) feature usage etc. This revealed (maybe not surprisingly) that the most use feature is the query editor. So for this release, the query editor has received a lot of attention. In addtion to the changes below, the general layout of the editor has been streamlined (no more rounded corners). The first button is new, and will open a “New Qery” window against the same database file. An options dropdown have been added to expose some of the (maybe overlooked) options that are available for the query editor. Setting these only affects the current query window, use the general settings (which you can reach via the Setting button in the query editor now) to change the “default��� value for a setting. Lets have a quick look at each of the options: “Show result in Grid”: By default, the query results (from a SELECT statement) will be displayed as text for performance reasons, but you can opt-in to have the results displayed in an Excel like grid instead. “Show Binary Values in Result”: By default, binary values (from for example “image” or “rowversion” columns) will be displayed a “System.Byte”. Enabling this will instead display the actual value as a hexadecimal string – but may affect performance. “Show null values as NULL”: Until recently, NULL values were displayed as an empty string, not as “NULL”. Disabling this reverts to the old behaviour. “Ignore DDL errors”: Enabling this (per query window only) feature, allows you to run the database creation scripts generated by the Entity Framework “Generate Database from Model” feature, and ignore errors caused by for example pre-existing tables. “Use classic (plain) grid”: This will revert to using the “old” grid for grid results – about the “new” grid, see below!

New result grid in query editor

A new grid that allows you to further drill into the results of a query without writing any SQL is now the “default” result grid in the query editor. The grid uses http://wpfextendeddatagrid.codeplex.com/ “Autofilter” :The grid has built in filters, in the example above to filter on invoices for a particular customer (or even set of customers). “Grouping”: Add columns you want to group by to the surface above the grid. In the example above, Invoices are grouped by Customer Id.

Options now part of Visual Studio options dialog

The options for the Toolbox have finally been integrated in the standard Visual Studio Tools/Options pages.

Improved SQL Server support

SQL Server Connections defined in Server Explorer now appear in the Toolbox, in order to better expose the SQL Server releated features of the Toolbox: And scripting of a SQLite schema (only) based on a SQL Server database is now possible: Improvements A number of smaller improvements are also included in this release: Improve format of INSERT statements generated by CSV import (to make the more readable) Added latest System.Data.SQLite version (1.0.99) Added link to blog post to DataAccess.cs to better explain how to use it. Support for row-returning SQLite statements beginning with "WITH" Added "Feedback" button Using Azure Application Insights for metrics and crash reports Ability to remove password from password protected SQL Compact file (by leaving password box blank) Progress messages during export now displayed in Output window Enable scripting of hierarchyid as varbinary(892) Now able to script Adventureworks2014 schema and data to both SQL Compact and SQLite without errors Table Data script (INSERTs) now have "RESEED" command at end always Option to Opt out of Telemetry added Bug fixes In addition to the above improvements and features, and number of bug fixes are included in this release: API: Fix bug in SQLMetal.exe detection (on some configurations) SQLite CREATE TABLE datetime default should be current_timestamp, not GETDATE() Improved SQLite datetime handling in SELECT and Edit in Grid User Interface: CSV export from the SQL editor included one separator too many in the heading Editor keyboard bugs fixed Scroll issues in treeview fixed Autohide of Toolbox bug fixed Table builder: Table builder was not scripting default values Table builder should not script default value for IDENTITY columns

SQL Server hierarchyid

In SQL Server 2008, Microsoft introduced the hierarchyid data type.  While an application is responsible for populating this field (i.e. it does not automatically generate a tree), the built-in functions provided with this data type make it a much better option than simply storing an objects parent ID and performing recursive joins to find its parent, grandparent, etc...  Many folks are not familiar with this data type so I thought I'd write a quick example.

In the example below, I've created a fake medical institution with a couple divisions and departments.  Navigating through the organization is a snap using the built-in hierarchyid functions.

-- First setup some example data: begin try drop table #structure end try begin catch end catch create table #structure ( structure_id hierarchyid, organization_nm varchar(100), organization_abbr varchar(10) ) insert into #structure(structure_id, organization_nm, organization_abbr) values ('/0/','Tavernier Medical Sciences','TMS'), ('/0/1/','Preventative Care','PC'), ('/0/1/1/','Snakeoil Group','SO'), ('/0/1/2/','Blood-Letting','BL'), ('/0/1/2/1/','Hall 1','H1'), ('/0/1/2/1/1/','Bed A','BA'), ('/0/1/2/2/','Hall 2','H2'), ('/0/2/','Surgery','SG'), ('/0/2/1/','Transplants','TR'), ('/0/2/1/1/','Brain','BR'), ('/0/2/1/2/','Wings','WN'), ('/0/2/2/','Elective','EL'), ('/0/2/2/1/','Cyclops Creation','CC'), ('/0/2/2/2/','Centaur Addition','CA') -- Example queries: -- Get everything related under our Surgery division: select *, s.structure_id.GetLevel() as lvl, s.structure_id.ToString() as readable from #structure s where s.structure_id.IsDescendantOf('/0/2/') = 1 order by s.structure_id; -- Get everything that has the Blood-Letting department as its parent: select *, s.structure_id.GetLevel() as lvl, s.structure_id.ToString() as readable from #structure s where s.structure_id.GetAncestor('1') = cast('/0/1/2/' as hierarchyid) order by s.structure_id; -- List everything and it's parent: select s.*, s2.organization_nm as parent from #structure s left outer join #structure s2 on s.structure_id.GetAncestor(1) = s2.structure_id order by s.structure_id; -- List everything and it's grandparent: select s.*, s2.organization_nm as two_levels_up from #structure s left outer join #structure s2 on s.structure_id.GetAncestor(2) = s2.structure_id order by s.structure_id; -- Divisions in TMS: select * from #structure s where s.structure_id.GetLevel() = 2 order by s.structure_id;

Example result set for first query:
