How to implement a conditional Upsert stored procedure?

Question

I\'m trying to implement your basic UPSERT functionality, but with a twist: sometimes I don\'t want to actually update an existing row.

Essentially I\'m trying to synchr

Answer 1

I'd drop the transaction.

Plus the @@rowcount probably would work, but using global variables as a conditional check will lead to bugs.

Just do an Exists() check. You have to make a pass through the table anyhow, so speed is not the issue.

No need for the transaction as far as I can see.
