Michael, It seemed to replicate just fine. At least in test. (5.1.22RC). I believe that we are using statement level replication which might be triggering the trigger on the slave node. I noticed that the triggers themselves also replicatated to the slaves, which is something I didn't expect. Gary

I seem to recall that several approaches to logically replicate triggers have been tried, where are we at these days? -- - michael dykman - [EMAIL PROTECTED] - All models are wrong.
