SSRS中存储过程中的多个数据集

Question

I have a SP that returns four different result sets, but for it to be used in SSRS report i need to have it configured in a proper way.

USE LearnShare
GO

IF OBJECT_ID (N'dbo.JH_LearnShare_ActiveUsers', N'P') IS NOT NULL 
DROP PROCEDURE dbo.JH_LearnShare_ActiveUsers
GO
    CREATE PROCEDURE dbo.JH_LearnShare_ActiveUsers
        @enddate as date
    AS
    Begin
--Declare @enddate as date
--set @enddate = '6/30/2014'
    Select COUNT (distinct p.PersonID) as [Total Active Users] --50621
    FROM Enrollment E inner join 
    Person p on p.PersonID = e.[Person ID]
    WHERE p.active = 1
    and FirstLaunch between DATEADD(m,-11,DATEADD(mm, DATEDIFF(m,0,@enddate), 0)) AND @enddate
--DATEADD(m,-11,DATEADD(mm, DATEDIFF(m,0,GETDATE()), 0)) AND GETDATE()
    and [Completion Date] between  DATEADD(m,-11,DATEADD(mm, DATEDIFF(m,0,@enddate), 0))   AND @enddate
--and convert(varchar(10),[Enrollment Date] , 120) < convert(varchar(10),FirstLaunch , 120) --118669
--and FirstLaunch <> '1900-01-01 00:00:00.000' -- this doesn't matter when adding [completion date] in where clause


    Select COUNT (distinct p.PersonID) as [Total Active Online Users] --49269
    FROM Enrollment E inner join 
    Person p on p.PersonID = e.[Person ID]
    left join class c
    on e.[resource id] = c.[resource id] 
    WHERE p.active = 1
    and FirstLaunch between DATEADD(m,-11,DATEADD(mm, DATEDIFF(m,0,@enddate), 0)) AND @enddate
--DATEADD(m,-11,DATEADD(mm, DATEDIFF(m,0,GETDATE()), 0)) AND GETDATE()
    and [Completion Date] between  DATEADD(m,-11,DATEADD(mm, DATEDIFF(m,0,@enddate), 0)) AND @enddate
    and c.[Resource ID] is null 


    select COUNT (distinct p.personID) as [User with ILT courses] --22656
    from Person p 
    inner join Enrollment e on p.PersonID = e.[Person ID]
    inner join Resources r on e.[Resource ID] = r.[Resource ID]
    inner join Class c on r.[Resource ID] = c.[Resource ID]
    where p.Active = 1
    and c.[Class Date] between DATEADD(m,-11,DATEADD(mm, DATEDIFF(m,0,@enddate), 0)) AND @enddate
    and e.FirstLaunch between DATEADD(m,-11,DATEADD(mm, DATEDIFF(m,0,@enddate), 0)) AND @enddate
--DATEADD(m,-11,DATEADD(mm, DATEDIFF(m,0,GETDATE()), 0)) AND GETDATE()
    and e.[Completion Date] between  DATEADD(m,-11,DATEADD(mm, DATEDIFF(m,0,@enddate), 0)) AND @enddate


    SELECT DateName(yyyy, FirstLaunch) EnrollmentYear, DATENAME(month, FirstLaunch) AS EnrollmentMonth , Count(distinct p.PersonID) as ActiveUsers --190312
    FROM Enrollment E inner join 
    Person p on p.PersonID = e.[Person ID]
    WHERE p.active = 1
    and FirstLaunch between DATEADD(m,-11,DATEADD(mm, DATEDIFF(m,0,@enddate), 0)) AND @enddate
    and [Completion Date] between DATEADD(m,-11,DATEADD(mm, DATEDIFF(m,0,@enddate), 0)) AND @enddate
--and convert(varchar(10),[Enrollment Date] , 120) < convert(varchar(10),FirstLaunch , 120) --118669
--and FirstLaunch <> '1900-01-01 00:00:00.000' -- this doesn't matter when adding [completion date] in where clause 
    AND [Completion Date] <> '1900-01-01 00:00:00.000'
    GROUP BY DateName(yyyy,FirstLaunch) , DATENAME(month,FirstLaunch), DATEPART(MONTH,FirstLaunch)
    ORDER BY DateName(yyyy,FirstLaunch) desc , DATEPART(MONTH,FirstLaunch) DESC

    End

I tried following

Create StoredProcedure sp_MultipleDataSets(@Param nvarchar(10))
as
begin
   if(@Param == "first")
      begin
         SELECT EMPID, ENAME, JOB, SAL, DEPTID FROM EMP -- first result set
      end
   if(@Param == "second")
      begin
        SELECT DEPTID, DNAME, LOC FROM DEPT --second result set
      end
end

Example adding if (@enddate == "first") begin select..... end but its giving me an error Msg 102, Level 15, State 1, Procedure JH_LearnShare_ActiveUsers, Line 15 Incorrect syntax near '='.

any help, please. Thanks!

I know this is late but maybe this response will help someone finding this later on.

You could write the SP in that way, however it seems unnecessarily complicated. There should be no reason you can't just write 4 different stored procedures. However, if you want to go down that route, that will work. EX:

IF @datasets = 1
begin
  select 1
end
IF @datasets = 2
begin
  select 2
end
