存储过程返回 int 值而不是实体框架中的结果集

Question

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,
         [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 
from ActivityPlan ap
left outer join Location l on ap.ActivityLocationID =l.ID left join Activity_Clients ac on ap.ActivityRecurrence_ID=ac.ActivityRecurrence_ID 
left outer join Client c on ac.Client_ID=c.ID
left outer join LeisureActivity orgla on ap.ActivityType=orgla.ID 
where ap.ActivityLeaderID in(0,@ActivityLeaderID) and c.[Status]=1

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


declare @Activities nvarchar(max)

--print 'before updation'
update @TempLeisureActivites
set Activity=@Activities,Location=@Locations

--print 'after updation'

FETCH NEXT
FROM @RecurIDsCursor INTO @TempAPID,@TempRecurID

SET @RecurIDsRowsCount=@RecurIDsRowsCount-1
END
CLOSE @RecurIDsCursor
DEALLOCATE @RecurIDsCursor


end
select * from @TempLeisureActivites
end

它在 SQL Server Management Studio 中执行时返回结果集，但在使用实体框架的 Asp.net MVC 中它返回一个整数而不是如下所示的结果集。

  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，但它对我没有帮助 (Stored procedure returns int instead of result set)。 我该如何解决我的问题？

Answer 1

ExecuteFunction() 方法以整数形式返回受影响的行数。

如果您希望它返回ObjectResult<YourEntityType>。 改成：

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

但我认为现在更好的做法是：

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