Firstly, I should say that I am new to the ADO. And I try to use ADOQuery do some SQL selections for me, it goes like the following: ... ADOQuery1->Close(); ADOQuery1->SQL->Text = "select * from extbl where field0 = ''" ADOQuery1->Open(); ADOQuery1->Close();// the error occurs here. ADOQuery1->SQL->Text = "select * from extble where field1 = ''" ADOQuery1->Open(); ... ---------------------------------------------------------------- And when there was no record matched the first SQL sentence, an exception occured with message like "BOF or EOF is true, or current record has been deleted..." Please give me a hand, thanks.
