Yesterday's Question of the Day (by Steve Jones - SSC Editor)

Using SQLCMD Variables

I am writing a SQLCMD script in SSMS with SQLCMD mode. I set a variable with this script (ignore the double backslashes for now):

:setvar DirectoryRootPath "Log.txt"

Now I want to use this variable in another part of the script. What would I put in the place of XXX in this code to use the variable value here:

SELECT 'XXX', myid, myname, mychar FROM dbo.MyTable;

Answer: '$(DirectoryRootPath)'

Explanation: The proper way to use this path in the SELECT is to use quotes and then surround the variable with $(). Ref: Edit SQLCMD Scripts with Query Editor - https://docs.microsoft.com/en-us/sql/ssms/scripting/edit-sqlcmd-scripts-with-query-editor?view=sql-server-ver15

Featured Script

Select Group Members from Logins

slesicki from SQLServerCentral

Know who all the individual group members are for a given WINDOWS_GROUP login. This script uses the sys.xp_logininfo procedure to find group members for each login on an instance. This is useful when attempting to remove orphaned WINDOWS_LOGINS. May have issues working across your logged in domain.
