[sql-server] sql server #region

can i create regions in sql server editor (like #region and #endregion in C#) ?

It is just a matter of using text indentation in the query editor.

Expanded View:

Collapsed View:

(I am developer of SSMSBoost add-in for SSMS)

We have recently added support for this syntax into our SSMSBoost add-in.

--#region [Optional Name]
--#endregion

It has also an option to automatically "recognize" regions when opening scripts.

I've used a technique similar to McVitie's, and only in stored procedures or scripts that are pretty long. I will break down certain functional portions like this:

BEGIN /** delete queries **/

DELETE FROM blah_blah

END /** delete queries **/

BEGIN /** update queries **/

UPDATE sometable SET something = 1

END /** update queries **/

This method shows up fairly nice in management studio and is really helpful in reviewing code. The collapsed piece looks sort of like:

BEGIN /** delete queries **/ ... /** delete queries **/

I actually prefer it this way because I know that my BEGIN matches with the END this way.

Not out of the box in Sql Server Management Studio, but it is a feature of the very good SSMS Tools Pack

No, #region does not exist in the T-SQL language.

You can get code-folding using begin-end blocks:

-- my region
begin
    -- code goes here
end

I'm not sure I'd recommend using them for this unless the code cannot be acceptably refactored by other means though!

BEGIN...END works, you just have to add a commented section. The easiest way to do this is to add a section name! Another route is to add a comment block. See below:

BEGIN  -- Section Name
/* 
Comment block some stuff  --end comment should be on next line
*/

 --Very long query
SELECT * FROM FOO
SELECT * FROM BAR
END

Another option is

if your purpose is analyse your query, Notepad+ has useful automatic wrapper for Sql.
