I answered this question yesterday. Why are you asking it again?

@jagjitsingh,

When I run into problems like the one's you're having, I go back to the basics.

The first step is to get out of the dynamic SQL world and get some regular code to work properly first. Then, you can work on making it dynamic and you'll be much more successful.

In fact... I lied a bit. I don't run into problems like the one's you're having because I always start with working code first. Then I convert it to dynamic SQL one parameter at a time.

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.
