======================================
CD->srvdb->StartTransaction();
CD->EQuery->Close();
CD->EQuery->SQL->Clear();
sprintf (str, "begin");
CD->EQuery->SQL->Add(str);
CD->EQuery->ExecSQL();
CD->EQuery->Close();
CD->EQuery->SQL->Clear();
sprintf (str, "lock mytable");
CD->EQuery->SQL->Add(str);
CD->EQuery->ExecSQL();
sprintf (str,"update mytable set \
active=1 where st = '2020201'" );
CD->EQuery->Close();
CD->EQuery->SQL->Clear();
CD->EQuery->SQL->Add(str);
CD->EQuery->ExecSQL();
CD->EQuery->SQL->Clear();
sprintf (str, "abort");
CD->EQuery->SQL->Add(str);
CD->EQuery->ExecSQL();
CD->srvdb->Rollback();
==============================
the field "active" save new value = 1 after
'abort' command.
