the error tells what the issue is, but it might be a little new to you for debugging these kinds of issues.

to really help; we'd have to see the code for the stored procedure; anything else we did would just be syntax guessing, which might just confuse everyone even more.

Try using dynamic SQL to concatinate the variable into your view. I assume you do not want the variable to be created as part of the view rather whatever the variables value is to be created in the view.

As Lowell said, providing the code will allow us to help you refactor it or tell you a better way to go... but barring that:

You can't use variables in a view. Instead of putting the 'create view' inside of a stored procedure, just use the variables in the stored procedure and do the select and don't create the view at all.

Consistency is only a virtue if you're not a screwup. 😉

I would try creating a table function instead of a view since you want to pass parameters; there are some limitations on what can be done in a function: http://msdn.microsoft.com/en-us/library/ms186755.aspx

Ummm.... why don't you just do a SELECT from the view with the correct WHERE clause? You don't need to add a variable to a view...

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.
