Question

I’m working on versioning our database and am now searching for a way to drop all stored procedures and functions from a C# Console Application. I’d rather not create a stored procedure that drops all stored procedures and functions. It has to be some sql executed from C#.

I tried to drop the stored procedure before creating it, but I got this message:

System.Data.SqlClient.SqlException:
‘CREATE/ALTER PROCEDURE’ must be the
first statement in a query batch.

Script for one SP for example:

DROP PROCEDURE [dbo].[sp_Economatic_LoadJournalEntryFeedbackByData]
SET ANSI_NULLS ON
SET QUOTED_IDENTIFIER ON
CREATE PROCEDURE [dbo].[sp_Economatic_LoadJournalEntryFeedbackByData]
    @Data VARCHAR(MAX)
AS
BEGIN
    ...
END

So I guess before creating all SP’s and functions I’ll need to drop all SP’s and functions first with one sql script.

You can check for existence before dropping:

IF EXISTS (SELECT * FROM [dbo].[sysobjects]
           WHERE ID = object_id(N'[dbo].[YourProcName]') AND 
                 OBJECTPROPERTY(id, N'IsProcedure') = 1)
    DROP PROCEDURE [dbo].[YourProcName]
GO

… then create it…

I would add this for each stored procedure you want to create.
