Regarding Creating Stored Procedures If One Does Not Exist

Hello,
Very quick question (I hope) regarding SQL Server:
I want to create a query that basically says that if a stored procedure (say
sproc_foo) does not exist, then create the stored procedure. I know that
there are easy ways to do this with creating tables/databases if they don't
exist, but how is this possible with stored procedures?
Regards,
James Simpson
Straightway Technologies Inc.Hi James,
You can try something like this
IF NOT EXISTS (SELECT * FROM sys.objects
WHERE object_id = OBJECT_ID(N'[dbo].[uspGetBillOfMaterials]')
AND type in (N'P', N'PC'))
BEGIN
CREATE PROCEDURE [dbo].[uspGetBillOfMaterials]
...
Hope this helps,

Alas, that will not work as is, since CREATE PROCEDURE must be the first
statement in a batch. Scripting from SQL Server 2005 with the If Not Exists
check turned on produces:
IF NOT EXISTS (SELECT * FROM sys.objects WHERE object_id =
OBJECT_ID(N'[dbo].[MyProc]') AND type in (N'P', N'PC'))
BEGIN
EXEC dbo.sp_executesql @.statement = N'
CREATE PROC [dbo].[MyProc]
@.Parm1 char(6)
AS
-- Do Something'
So, as you can see it is a 'dynamic SQL' implementation. (I believe that
there is a CONNECT request for something better than this.)

Ben - I tried the solution you gave and for whatever reason it does not
appear to work. I have also seen this type of example online and this query
fails miserably on SQL Server 2005 Express. Russel, the solution you gave
works perfectly, and hopefully Microsoft resolves this issue.

I agree with your note but that was not intended to be a final and complete
solution and my primary purpose was to show the IF NOT EXISTS part.
Perhaps it is like saying that your code does not work as is either, because
you have BEGIN but END is missing :-)

I also got the code using the SQL Server Scripts Wizard and the 'Include if
NOT EXISTS' option turned on. The problem was that I replaced EXEC
dbo.sp_executesql with CREATE PROCEDURE to make the code easier to read and
understand.
