ALTER? to alter a table, it would only need to occur once, ever, in the database; doesn't really belong in the procedure.

otherwise you end up having to test every time whether to do it or not, which, since it will occur once, wastes a little bit of time checking to see if it needs to be done.

so my advice is to rethink where to put the alter statement...i don't think it belongs in a procedure.

regardless, you'd have to do something like this:

CREATE PROCEDURE MyProc(@paramters int)

AS

BEGIN

IF NOT EXISTS (SELECT 1

from sys.objects objz

left outer join sys.columns colz

on objz.object_id = colz.objectid

where objz.name = 'MyTable'

and colz. name = 'MyColumn')

BEGIN --IF

ALTER TABLE MyTable ADD MyColumn sqlvariant

END --IF

UPDATE MyTable

SET SomeColumn = SomeValue

WHere AnotherColumn = @paramters

END --PROC

Could you please post your stored procedure code?

Without seeing what you can see it's hard to provide relevant help. Please read an article from the link at the bottom of my signature about this forum etiquette.

From your very vague description, I can only guess that you have to choices:

1. Create a separate stored proc which only performs UPDATE

2. Amend the existing one to have input parameter as a flag which will determine its behaviour.

Instead of including the code here, OP just duplicated the post:
