如何編寫預編譯查詢？

Question

有人可以幫助編寫以下代碼的預編譯查詢嗎？

Modal.StaffNo def = Staff.StaffNo.Where(a => 
a.Number1 == number1 && a.Number2 == number2 
).FirstOrDefault(); 

謝謝！

Answer 1

你可以寫上面linq的查詢，就像這樣。

SELECT TOP 1 * FROM StaffNo Where number1=@number1 and number2=@number2 

Answer 2

試試這個，希望我可以幫助你：

Modal.StaffNo def = (from o in Staff.StaffNo where o.Number1 == number1 && o.Number2 == number2 select o).FirstOrDefault();
