Check if Function EXISTS before adding Posted: 08 Jul 2013 04:43 AM PDT I'm trying to write of script that checks if a certain Function exists, and if it does not, create it. If the Function does exist, then the script should end without touching the function.I've tried writing it these ways[code="sql"]If NOT EXISTS (select * from sysobjects where name = 'FunctionName')CREATE FUNCTION --....-- andIF OBJECT_ID('FunctionName','IF') is nullCREATE FUNCTION --....[/code]I have read that CREATE FUINCTION cannot be combined with other statements in the batch and that the CREATE statement must start the batch. I've tried puting the CREATE inside BEGIN/END and parantheses. But I'm still getting syntax errors.Is the only option to use the syntax that drops the function when it already exists and create it every time?
