问题描述
我在SqlServer中有两个简单的存储过程:
I have two simple stored procedures in SqlServer:
-
SetData(@id int, @data varchar(10)) -
GetData(@id int).
SetData(@id int, @data varchar(10))GetData(@id int).
GetData当前返回单行，单列结果集，但是如果需要，我可以将其更改为适当的函数.
GetData currently returns a single-row, single-column result set, but I could change it to be a proper function if needed.
从DbContext实例执行这些操作的最佳方法是什么?
What would be the best way to execute these from a DbContext instance?
如果可能的话，我想避免做自己的连接状态管理和/或公开EF特定类型.我首先检索了ObjectContext并查看了Execute*函数，但是文档非常糟糕，并且缺少涉及存储过程的示例.
If possible, I'd like to avoid having to do my own connection state management and/or exposing EF-specific types. I started by retrieving the ObjectContext and looking at the Execute* functions, but the documentation is pretty bad and lacking examples involving stored procedures.
理想情况下，我希望能够做到这一点:
Ideally, I'd like to be able to do this:
myContext.ExecuteNonQuery("SetData", id, data);
var data = myContext.ExecuteScalar<string>("GetData", id);
推荐答案
DbContext提供了这些功能.使用:
DbContext offers these functions. Use:
IEumerable<...> result = myContext.Database.SqlQuery<...>(...)
执行检索存储过程和
int result = myContext.Database.ExecuteSqlCommand(...)
执行数据修改存储过程.
to execute data modification stored procedure.
