So I consider the transaction made and closed. > but if I looked in the db I still see the row/entry for 'loki' > Nope - you have only run the BEGIN part of the transaction. prepare() prepares only one single statement, not multiples (you have 4 statements in your SQL). Thus when you try to run another transaction, that BEGIN is still open. -- ----- stephan beal http://wanderinghorse.net/home/stephan/ http://gplus.to/sgbeal "Freedom is sloppy.
