If you haven't read up on the MERGE operation in TSQL, be sure to do so. It allows you to insert and update (and d elete if need be) in a single query. Look at the sample queries HERE and try to adapt them to your issue.
Hint: Example A is just what you're trying to do: Update where a row exists, and insert where a row doesn't exist.
If you have any questions, post your code up here and we'll have a look at it.

I prefer the individual commands rather than Merge. There have been too many problems with it for me to trust it.

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.
