My 2 cents on this regardless of platform is to take the low road. Sure you can set up tricky DATA/EXECUTE statements that you hope will work but somewhere along the way they will get out of sync.
I test things like consecutive selects, ie First Select for the majority and the second to fine tune (there are effeciency reasons). But if the first one fails, I don't want the second to process 'alone' and get far more (or zero) items than expected. Proc had the IF E = 401 blah, blah intermediate tests. There is a lot of status, Returning and, Capturing clauses to consider. Assume the worst and program around unvalidated data and the good stuff will prevail.
