Jim,

You can stack up multiple SQL commands inside a single SPT call. You should be careful because all these SQL statements can be interpretted as a single monolithic transaction on the server and there is a possibility that it may cause significant blocking issues. That would not be the case if you just did this as a SP which it really should be.
