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

Just in case if you are using SQL server 2016, then there is a shorter version to check if the proc exist and then drop and recreate it

USE [DATABASENAME]
GO
DROP PROCEDURE IF EXISTS 
GO
CREATE PROCEDURE 
AS
-- your script here
END
GO
GRANT EXECUTE ON  TO
