Hi, Ryan,
I followed your advice and removed XTransaction and all references to
it from TestButtonClick. But now I get an exception with the message
"Transaction not set". Any hint?

I'm sorry, the previous problem was SQLite-related, which I'm
initimately familiar with, but this one seems to be a Lazarus DB
component requirement which I'm not so much familiar with, but probably
has an easy solution someone here might know about.
The question becomes: How to execute a query, without a transaction
being set, using SQLdb in Lazarus?
I use zeos instead of sqldb. Most probably it's my fault and it could be
solved by doing what Michael said (use stoUseImplicit), but when I tried
to use sqldb with sqlite, as long as I kept the dataset open (to show
the data in a dbgrid) the table was locked and couldn't be modified by a
different thread/process.
Probably just a matter of different defaults (zeos doesn't need a
separate transaction component and the default TransactionIsolationLevel
is tiNone).
Bye
