我有这个存储过程

create procedure [dbo].[sp_GetAllLesiureActivitiesNew]
    (@ActivityLeaderID int = null)
as 
begin
    declare @TempLeisureActivites TABLE
        ([ActivityPlan_ID] [int]  NULL,

它在SQL Server Management Studio中执行时返回Result set，但在使用Entity Framework的Asp.net MVC中，它返回一个整数而不是结果集，如下所示。

  public virtual int sp_GetAllLesiureActivitiesNew(Nullable<int> activityLeaderID)
        {
            var activityLeaderIDParameter = activityLeaderID.HasValue ?
                new ObjectParameter("ActivityLeaderID", activityLeaderID) :
                new ObjectParameter("ActivityLeaderID", typeof(int));

            return ((IObjectContextAdapter)this).ObjectContext.ExecuteFunction("sp_GetAllLesiureActivitiesNew", activityLeaderIDParameter);
        }

我发现了一篇文章，但它对我没有帮助（Stored procedure returns int instead of result set）。我怎么能解决我的问题？

Answer 1

ExecuteFunction（）方法返回受整数影响的行数。

如果您希望它返回ObjectResult<YourEntityType>。将其更改为：

return ((IObjectContextAdapter)this).ObjectContext.ExecuteFunction<YourEntityType>("sp_GetAllLesiureActivitiesNew", activityLeaderIDParameter);

但我认为现在更好的方法是：

Dbcontext.Database.SqlQuery<YourEntityType>("storedProcedureName",params);

Here是一篇展示示例的文章。

存储过程返回int值而不是Entity Framework中的结果集
