Procedure created with CREATE PROCEDURE Defaults with ALTER PROCEDURE - sql

Question

I have a SQL Script that creates a procedure that looks like this:
IF OBJECT_ID('dbo.InitMyTable') IS NOT NULL
DROP PROCEDURE [dbo].[InitMyTable]
GO
CREATE PROCEDURE [dbo].[InitMyTable] AS
BEGIN
CREATE TABLE MyTable (
ID int,
Name varchar(16),
Data text
);
END
And it creates a procedure that looks like this:
GO
/****** Object: StoredProcedure [dbo].[InitMyTable] Script Date: 5/19/2017 12:30:45 PM ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER PROCEDURE [dbo].[InitMyTable] AS
BEGIN
CREATE TABLE myTable (
ID int,
Name varchar(16),
Data text
);
END
My issue is that the created procedure does not create the table, but when I remove the line
ALTER PROCEDURE [dbo].[InitMyTable] AS
It obviously works fine.
How can I create a script that produces a procedure without that line?

Answer 1

It looks like you scripted out the stored procedure somehow-- possibly in SQL Server Management Studio (SSMS) by right-clicking the proc in the Object Explorer window and clicking "Modify". When you do this, SSMS generates a script for you that will alter the existing stored procedure.
The DDL statements below create the procedure, but they are not part of the procedure:
IF OBJECT_ID('dbo.InitMyTable') IS NOT NULL
DROP PROCEDURE [dbo].[InitMyTable]
GO
CREATE PROCEDURE [dbo].[InitMyTable] AS
The same thing applies to the code generated by SSMS. SSMS has generated code that can alter an existing stored procedure, but the DDL below is not actually part of the proc itself:
/****** Object: StoredProcedure [dbo].[InitMyTable] Script Date: 5/19/2017 12:30:45 PM ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER PROCEDURE [dbo].[InitMyTable] AS
The stored procedure code itself is still there:
CREATE TABLE MyTable (
ID int,
Name varchar(16),
Data text
);
Note that if this stored procedure is run twice, it will fail, because the table MyTable will already exist. To avoid this error, the procedure could first check to see if the table exists:
if not exists (select 1 from sys.tables where name = 'MyTable')
begin
create table MyTable...
end
