I really like Microsoft philosophy nowadays, they are putting a lot of time developing good open source tools like SQLCLI, SQLOps and Visual Studio Code, those tools has something in common “a built-in terminal” a multi-platform and code geek like me really appreciate those details. It is pretty neat to use the built-int terminal to do stuff without leaving your development environment. This functionality is also available on SSMS (in some way), it is called SQLCMD mode.
This feature allows you to interact directly with Windows command line without leaving your SSMS environment, for example long time ago I had the need to generate a SQL file from an output of a query, I knew I can use SQLCMD for such thing but I didn’t want to create an external script to be call from command … so I did my research and figure out SQLCMD mode in SSMS can do such thing without having to run outside SSMS.
Here is how you can enable SQLCMD mode in SSMS:
Alright! so, now let’s do a quick example. Imagine you don’t want to lose the list of roles assigned to all your database users for a specific database, in order to script out the roles we will run a query and generate an output directly to Windows having the T-SQL script ready to run when needed.
Here is the T-SQL code:
BEGIN SET NOCOUNT ON :OUT F:\MyDB_Roles.sql DECLARE @Role varchar(255) SET @Role= '%' -- Add Users to roles SELECT 'EXEC sp_addrolemember ''' + RTrim(r.name) + ''',''' + RTrim(Coalesce(l.name,u.name)) + '''' as '-- Add Role Users' FROM dbo.sysusers u INNER JOIN sysmembers m ON u.uid = m.memberuid INNER JOIN sysusers r ON m.groupuid = r.uid LEFT OUTER JOIN master.dbo.syslogins l ON u.sid = l.sid WHERE r.issqlrole = 1 AND u.name &amp;amp;amp;amp;amp;amp;amp;lt;&amp;amp;amp;amp;amp;amp;amp;gt; 'dbo' AND r.name LIKE '%' ORDER BY r.name,u.name PRINT '-- End of script' END
Note the third line, I’m using the
:OUT command which will take care of redirecting the query result into a SQL file within Windows:
Once the query is executed, here is how the SQL File output file looks from Visual Studio code:
As you can see this is a normal T-SQL script generated from SSMS, it contains the roles we wanted to script out from our database. As you may realize by now this is a very handy option in SSMS, and to be fair with SQLCMD mode this is just a simple use case there is more scenarios where this SSMS functionality can help you to achieve very neat things.
