Multiple data sets in stored procedure in SSRS - sql

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
