VS SR Report joining data from multiple Data sets? - sql

Question

Wondering if anyone can help me, I am currently learning, SRSS Reports and have been tasked with a Pay & Display vehicle registration report, for staff and student carparks, to show if they are registered for P&D. I have the report laid out as a 3 table column; Name, Vehicle Number and Vehicle Registration. I have from the below code set out in my datasets the Vehicle Number and Vehicle Registrations pulling through, with a parameter to filter out if is staff or student pay and display. However I am having difficulty with pulling the Staff and Student names into one name column as they are through two different datasets. Can anyone be of help at all please? TIA
**-- Pay & Display Carpark Details Dataset**
SELECT * FROM Carpark_Vehicles
WHERE VehicleCustNo IN (SELECT CustID FROM [dbo].[Carpark_Customer]
WHERE CarParkID IN (SELECT CarParkID FROM [dbo].[Carpark_CarPark]
WHERE CTypeID IN ('PD', 'SPD')))
--and CTypeID IN (#Carpark_type))
**--Vehicle Details Dataset**
SELECT
Carpark_Vehicles.VehicleID
,Carpark_Vehicles.RegNo
,VehicleCustNo
FROM
Carpark_Vehicles
WHERE CarPark_Vehicles.RegNo = #RegNo
**--Staff details dataset**
SELECT
StaffDetails_StaffandLeaverDetails.StaffNumber
,StaffDetails_StaffandLeaverDetails.LastName
,StaffDetails_StaffandLeaverDetails.Name1
FROM
StaffDetails_StaffandLeaverDetails
**--Student details dataset**
SELECT
Student_CurrentStudentDetails.StudentNumber
,Student_CurrentStudentDetails.StudentID
,Student_CurrentStudentDetails.LastName
,Student_CurrentStudentDetails.FirstName
FROM
Student_CurrentStudentDetails
**--Carpark permit type (Pay & Display) parameter**
SELECT DISTINCT
CTypeID, CASE CTypeID WHEN 'abc' THEN 'Students' WHEN 'abc' THEN 'Staff' END AS Label
FROM
Carpark_Customer
WHERE CTypeID IN ('abc', 'Abc')

For your req I just took some sample data. This entire example will give you Idea how to achieve your final result.
Note: this is just showing you way how to achieve it, you have to modify as per your req.
Student and Staff Info from 2 different Tables
Registration Info from another separate Table
Your Final Result when Student as parameter is selected
Your Final Result when Staff as parameter is selected
Now how did I achieved this?
My Design for Final Result
Row visibilty expression for your final result Table in SSRS
Expressiion as below
=IIF(Parameters!ReportParameter1.Value=1,
IIF(Isnothing(Lookup(Fields!PersonId.Value,Fields!PersonId.Value,Fields!Name.Value, "DSStudentInfo")),true,false),
IIF(Isnothing(Lookup(Fields!PersonId.Value,Fields!PersonId.Value,Fields!Name.Value, "DSStaffInfo")),true,
false)
)
first Name column visibility
second column name visibility
First Name data value expression
=Lookup(Fields!PersonId.Value,Fields!PersonId.Value,Fields!Name.Value, "DSStudentInfo")
second name data value expression
=Lookup(Fields!PersonId.Value,Fields!PersonId.Value,Fields!Name.Value, "DSStaffInfo")
