OK, sorry, it needed to be
with TIBODataset(Dataset) do begin...

What is the SQL Monitor telling you?

Also, have you tried placing the parameter assignment code into the AfterPrepare event instead of BeforeOpen?

It shouldn't be a problem if you a using TIBODatabase - as long as the queries are properly connected to it...if not, and the datasets are forming their own connections, it's a guess that the transaction might not actually be started at the time the BeforeOpen event runs.

The monitor should indicate what is going on.

Please would you trim your messages. Thanks.
