SQL Server ':setvar' Error

Question

I am trying to create some script variables in T-SQL as follows:

    /*
    Deployment script for MesProduction_Preloaded_KLM_MesSap
    */

    GO
    SET A         


        

Answer 1

The :setvar only works in SQL command mode, so you are possibly within normal SQL execution in the management studio and have not swapped to command mode.

This can be done through the user interface in SQL Server Management Studio by going to the "Query" menu, and selecting "SQLCMD mode."
