What if you wanted to continue with another statement if the user existed. IF NOT EXISTS(SELECT name FROM sys.server_principals WHERE name = 'test_user') BEGIN CREATE LOGIN test_user WITH PASSWORD = 'Password123' END If it does exist how can we carry on executing other statements or can we just exit. I'm doing this within my Delphi application and it crashes. I run 3 procedures from the one button click and the ckeck for user is the first. If user exists it halts the program. Is there not and IF THEN ELSE in SQL? This is great!!!! but…..

BEGIN
CREATE LOGIN test_user WITH PASSWORD = ‘Password123′
