问题描述
我有一个包含三个参数的存储过程,我一直在尝试使用以下方法返回结果:
I have a stored procedure that has three parameters and I've been trying to use the following to return the results:
context.Database.SqlQuery<myEntityType>("mySpName", param1, param2, param3);
起初我尝试使用 SqlParameter
对象作为参数,但这不起作用并抛出了 SqlException
并显示以下消息:
At first I tried using SqlParameter
objects as the params but this didn't work and threw a SqlException
with the following message:
过程或函数mySpName"需要参数@param1",但未提供.
Procedure or function 'mySpName' expects parameter '@param1', which was not supplied.
所以我的问题是如何将此方法与需要参数的存储过程一起使用?
So my question is how you can use this method with a stored procedure that expects parameters?
谢谢.
推荐答案
您应该通过以下方式提供 SqlParameter 实例:
You should supply the SqlParameter instances in the following way:
context.Database.SqlQuery<myEntityType>(
"mySpName @param1, @param2, @param3",
new SqlParameter("param1", param1),
new SqlParameter("param2", param2),
new SqlParameter("param3", param3)
);
