I can't remember the odbc driver insides well enough, but I'll check
tomorrow. Maybe Byron is listening? Anyway, I use ODBCExpress with Delphi
in both forms and grids without trouble. But I don't use COMMITs or ABORTs
directly. The OE api handles all the low end stuff quite well when using
grids and such. I'll use exception handling when executing hstmt sql
statements. I only need to close/reopen datasets when keeping detail
datasets current with their master. OE is (was?) sometimes not reliable
with automatic master/detail grids. But I've never had to close/reopen with
each insert/update/delete in a dataset.
