DLookup在分配给控制源之前执行

Question

以下是我的代码：

Forms![OrderForm]![Sku].ControlSource = 
"=DLookUp(""[Sku]"",""OrderTable"",
""ItemNumber = '" & Forms![OrderForm]![ItemNumber] & "')"

我运行上面的代码，控制源现在是：

=DLookUp("[Sku]","OrderTable",
"ItemNumber = '1234-BA')

如何更改我的代码，以便在控制源中看到以下内容：

=DLookUp("[Sku]","OrderTable",
"ItemNumber = '" & Forms![OrderForm]![ItemNumber] & "')

Answer 1

试试这个：

"=DLookUp(""Sku"",""OrderTable"",""ItemNumber='"" & "Forms![OrderForm]![ItemNumber]" & ""'"")"
