Question : Deadly Script?

Experts,

Every time I run the attached script, I can no longer query the Agents table, as if its index is fried or something. Is there anything you can see in this script that you think would cause this problem?

Answer : Deadly Script?

There are 2 BEGIN TRANSACTION statements. You need to commit both of them if you want to query any table modified by your script via a second query window.
