Creating a stored procedure if it does not already exist

Question

I want to check if a list of stored procedures exist. I want this all to be done in 1 script, one by one. So far I have this format:

USE [myDatabase]
GO

IF NO         


        

Answer 1

USE [myDatabase]
GO

IF EXISTS (SELECT * FROM sys.objects WHERE type = 'P' AND name = 'sp_1')
BEGIN
  DROP PROCEDURE sp_1
END
GO   --<-- Add a Batch Separator here



CREATE PROCEDURE sp_1
AS

END
GO
