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 NOT EXISTS (SELECT * FROM sys.objects WHERE type = 'P' AND name = 'sp_1')
BEGIN
CREATE PROCEDURE sp_1
AS
.................
END
GO
IF NOT EXISTS (SELECT * FROM sys.objects WHERE type = 'P' AND name = 'sp_2')
BEGIN
CREATE PROCEDURE sp_2
AS
.................
END
GO
and so on. However, I'm getting the following error:
Incorrect syntax near the keyword 'Procedure'.
Why isn't what I'm doing working correctly?
CREATE PROCEDURE
must be the first statement in the batch. I usually do something like this:
IF EXISTS (
SELECT type_desc, type
FROM sys.procedures WITH(NOLOCK)
WHERE NAME = 'myProc'
AND type = 'P'
)
DROP PROCEDURE dbo.myProc
GO
CREATE PROC dbo.myProc
AS
....
GO
GRANT EXECUTE ON dbo.myProc TO MyUser
(don't forget grant statements since they'll be lost if you recreate your proc)
One other thing to consider when you are deploying stored procedures is that a drop can succeed and a create fail. I always write my SQL scripts with a rollback in the event of a problem. Just make sure you don't accidentally delete the commit/rollback code at the end, otherwise your DBA might crane-kick you in the trachea :)
BEGIN TRAN
IF EXISTS (
SELECT type_desc, type
FROM sys.procedures WITH(NOLOCK)
WHERE NAME = 'myProc'
AND type = 'P'
)
DROP PROCEDURE myProc GO
CREATE PROCEDURE myProc
AS
--proc logic here
GO
-- BEGIN DO NOT REMOVE THIS CODE (it commits or rolls back the stored procedure drop)
IF EXISTS(
SELECT 1
FROM sys.procedures WITH(NOLOCK)
WHERE NAME = 'myProc'
AND type = 'P'
)
COMMIT TRAN
ELSE
ROLLBACK TRAN
-- END DO NOT REMOVE THIS CODE
