I have a stored procedure on a SQL Server 2005 database which has a statement like this:

  IF @Condition = 0
    BEGIN
        RAISERROR(\'some error message         


        

Answer 1

From the Books online

Specify a severity of 10 or lower to use RAISERROR to return a message from a TRY block without invoking the CATCH block.
