Ssrs 2008 r2 report dataset call a stored procedure

Question

I am modifying an existing SSRS 2008 r2 report. In a dataset that already exists within the ssrs 2008 r2 report I need execute
a stored procedure called StudentData and pass 3 parameter values to the stored procedure. The stored procedure will then return 5 values that are now needed for the modified ssrs report. My problem is I do not know how to have the dataset call the stored procedure
with the 3 parameter values and pass back the 5 different unique data values that I am looking for.
The basic dataset is the following:
SELECT  SchoolNumber,
        SchoolName,
        StudentNumber,      
 from [Trans].[dbo].[Student]
 order by SchoolNumber,
          SchoolName,
          StudentNumber
I basically want to pass the 3 parameters of SchoolNumber, SchoolName, and StudentNumber to the
stored procedure called StudentData from the data I obtain from the [Trans].[dbo].[Student]. The 3 parameter values will be obtained from the sql listed above.
The  columns that I need from the stored procedure called  StudentData will return the following data columns
that I need for the report: StudnentName, StudentAddress, Studentbirthdate, StudentPhoneNumber, GuardianName.
Thus can you show me how to setup the sql to meet this requirement I have?

Hi wendy,
After testing the issue in my local environment, we can refer to the following steps to achieve your requirement:
Create three multiple parameters named SchoolNumber, SchoolName and StudentNumber in the report. Those available values from the basic dataset SchoolNumber, SchoolName and StudentNumber fields.
If you want to pass multiple values parameter to stored procedure, we should create a function as below to the database:
CREATE FUNCTION SplitParameterValues (@InputString NVARCHAR(max), @SplitChar VARCHAR(5))
RETURNS @ValuesList TABLE
param NVARCHAR(255)
AS
BEGIN
DECLARE @ListValue NVARCHAR(max)
SET @InputString = @InputString + @SplitChar
WHILE @InputString!= @SplitChar
BEGIN
SELECT @ListValue = SUBSTRING(@InputString , 1, (CHARINDEX(@SplitChar, @InputString)-1))
IF (CHARINDEX(@SplitChar, @InputString) + len(@SplitChar))>(LEN(@InputString))
BEGIN
SET @InputString=@SplitChar
END
ELSE
BEGIN
SELECT @InputString = SUBSTRING(@InputString, (CHARINDEX(@SplitChar, @InputString) + len(@SplitChar)) , LEN(@InputString)-(CHARINDEX(@SplitChar, @InputString)+ len(@SplitChar)-1) )
END
INSERT INTO @ValuesList VALUES( @ListValue)
END
RETURN
END
Use the query below to create a stored procedure, then use it to create a dataset to return 5 values:
create proc proc_test(@SchoolNumber nvarchar(50),@SchoolName nvarchar(50),@StudentNumber nvarchar(50))
as
begin
select StudnentName, StudentAddress, Studentbirthdate, StudentPhoneNumber, GuardianName
from table7 where SchoolNumber in (SELECT * FROM SplitParameterValues (@SchoolNumber,','))  and SchoolName in(SELECT * FROM SplitParameterValues (@SchoolName,','))  and StudentNumber in (SELECT * FROM SplitParameterValues (@StudentNumber,','))
end
Right-click the new dataset to modify the parameter value in the Parameters pane as below:
=join(Parameters!SchoolNumber.Value,",")
=join(Parameters!SchoolName.Value,",")
=join(Parameters!StudentNumber.Value,",")
