如何编写预编译查询？

Question

有人可以帮助为以下代码编写预编译查询吗？

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

感谢!!!

Answer 1

您可以编写上面这样的linq查询。

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

Answer 2

试试这个，希望我能帮到你：

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