혹 Commit 했나요?

Database1.StartTransaction;

   with query5 do
    begin
    sql.clear;
   sql.add(' insert into T00_04M                                           ');
    sql.add(' (N_OWNER, YY_GWASE, A_BASE, D_ACCT_SETT,R_RATE,  AREA_BUD,    ');

이렇게 해줘도 그래염.. ㅠ.ㅜ 모가 잘못된건가염???

Try
    ExecSQL;
     Database1.Commit;
Except
    Database1.RollBack;
    ShowMessage('INSERT 실패');
End;

이런식으로 해보세요...

즐프하세요...

저....죄송해염..
아래와 같이 하니까...
ExecSQL;     <-------- 이부분에서
멈춰서 돌생각을 안해염...
ㅡㅡ;

먼저 Database1.StartTransaction을 하신후에 하시기바랍니다.

Try
    Database1.StartTransaction;
    ExecSQL;
    Database1.Commit;
Except
    Database1.RollBack;
    ShowMessage('INSERT 실패');
End;
