更正以下:还是错,运行不错,显示不出???begin
with ADODataSet1 do begin
close;
CommandType:=cmdText;
commandText:='select productToFactory from productlist where productToFactory<1';open;
while not ADODataSet1.eof do begin
mych:=ADODataSet1.FieldByName('productToFactory').asstring;
mych1:=copy(mych,1,1);
if mych1='0' then begin QRDBText5.Caption :=format('0%s',[mych]);exit;end//next;
end;
end;
