Delphi Xe2根据另一个表中的值将记录插入表中

Question

我有以下代码用于更新数据库中的表，此代码用于使用 zeosdblib 查询组件在 bds 2006 中工作，但现在它在 delphi xe2 中不起作用。谁能告诉我我哪里出错了。谢谢你

procedure TGoodsReceivedForm.btnCategorizeClick(Sender: TObject);
var
  TempCatTotal : Extended;
  nCatogory : string;
begin
TempCatTotal := 0;
zroqryExpcat.Open;
with zroqryExpcat do
begin
 first;
while not Eof do
begin
 zqrySumCategory.Close;
 zqrySumCategory.SQL.Clear;
 zqrySumCategory.SQL.Add('select costcategory,packcost,sum(qty)*packcost as pamount');
 zqrySumCategory.SQL.Add('from pitems');
 zqrySumCategory.SQL.Add('where costcategory=:costcategory and orderno=:orderno');
 zqrySumCategory.SQL.Add('group by costcategory,packcost');
 zqrySumCategory.Params[0].AsString := zroqryExpcat.FieldByName('Description').Value;
 zqrySumCategory.Params[1].AsString := NewPurchaseOrderForm.OrderNumber.Caption ;
 zqrySumCategory.Open;
 zqrySumCategory.First;
 TempCatTotal := 0;
 while not zqrySumCategory.eof do
 begin
  TempCatTotal := TempCatTotal+zqrySumCategory.FieldByName('pamount').AsFloat;
  zqrySumCategory.Next;
 end;
 if TempCatTotal > 0 then
 begin
  zqryInsertExpense.Close;
  zqryInsertExpense.Params[0].AsString := NewPurchaseOrderForm.OrderNumber.Caption ;
  zqryInsertExpense.Params[1].AsString := zqrySumCategory.Params[0].AsString ;
  zqryInsertExpense.Params[2].AsCurrency := TempCatTotal;
  zqryInsertExpense.Params[3].Asinteger := zroqryExpcat.FieldByName('gl_account_no').Value;
  zqryInsertExpense.Params[4].AsDate := ReceivedDate.Date;
  zqryInsertExpense.ExecSQL;
  zqryInsertExpense.Close;
end;
next;
end;
end;
  zqryListExpenseCat.Close;
  zqryListExpenseCat.Params[0].Value := NewPurchaseOrderForm.OrderNumber.Caption;
  zqryListExpenseCat.Open;
end;

您在该行中缺少'：

zqryInsertExpense.Params[3].Asinteger := zroqryExpcat.FieldByName  (gl_account_no').Value;

在 FieldByName( 附近。你确定你正确粘贴了这段代码吗？
