存儲過程返回int值，而不是在實體結果集框架

Question

我有這個存儲過程

create procedure [dbo].[sp_GetAllLesiureActivitiesNew] 
    (@ActivityLeaderID int = null) 
as 
begin 
    declare @TempLeisureActivites TABLE 
     ([ActivityPlan_ID] [int] NULL, 
     [ActivityRecurrence_ID] [int] NULL, 
     [ActivityName] [nvarchar](50) NULL, 
     [Activity] [nvarchar](max) NULL, 
     [IsResponse] [bit] NULL, 
     [IsLOI] [bit] NULL, 
     [clientcount] [int] NULL, 
     [Location] [nvarchar](max) NULL, 
     [StartDateTime] [datetime] NULL, 
     [EndDatetime] [datetime] NULL) 

    insert into @TempLeisureActivites 
     select distinct 
      ap.ActivityPlan_ID, ap.ActivityRecurrence_ID, 
      ap.ActivityName, orgla.Activity, orgla.IsResponse, 
      orgla.IsLOI, 
      (select count(distinct cc.ID) from Client cc join Activity_Clients acc on cc.ID=acc.Client_ID join ActivityPlan app on acc.ActivityRecurrence_ID=app.ActivityRecurrence_ID where app.ActivityRecurrence_ID=ap.ActivityRecurrence_ID and cc.Status=1) as clientcount,l.Location,ap.StartDateTime,ap.EndDatetime

    if(@ActivityLeaderID is not null and @ActivityLeaderID>0) 
    begin

select * from @TempLeisureActivites

它返回結果，而使用實體框架，它返回一個在SQL Server Management Studio，但在Asp.net MVC執行設置整數而不是如下所示的結果集。

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); 
     } 

我找到了一篇文章，但它不幫我（Stored procedure returns int instead of result set）。 我如何解決我的問題？

Answer 1

ExecuteFunction（）方法返回作爲整數受到影響的行數。

如果你想要它返回ObjectResult<YourEntityType>來代替。 將其更改爲：

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

但我認爲，這樣做的更好的方法是現在：

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

Here的一篇文章，給出了一個例子。
