Thank you. This page makes it clear why the last search started a
transaction, which at the end is pending due to a missing COMMIT.
On the other hand, when we would set EXEC SQL SET AUTOCOMMIT TO ON, when does
the transaction block starts exactly (which could be rolled back), as
there is no EXEC SQL BEGIN?
Thanks again
