SSRS Tutorial Part 89- CasCading Parameters with Dynamic SQL in Stored Procedures in SSRS Report

In this video of SSRS Series, we are going to work on Cascade Parameter. I got this question from one of the visitor.

here is the scenario
He would like to provide facility to his users to choose the Column name from the Drop down( Parameter). Once the Column name is chosen then Next parameter should show values available in the table for that column ( Cascaded Parameter). The user should be able to choose multiple values if he/she like. Once user choose the values for parameter, He/She should be able to see the results as per values provided in the parameters.

Let's create the Main Query with two Parameters

-- Main Query 
CREATEPROCEDURE dbo.MainQuery
  @ColumnName VARCHAR(100),
  @ValuesVARCHAR(MAX)
AS
BEGIN
IF OBJECT_ID('tempdb..##Temp') ISNOTNULL
DROPTABLE ##Temp
DECLARE @Val VARCHAR(MAX)
SET @Val=Replace(@Values,',',''',''')

DECLARE @SQL NVARCHAR(MAX)
SET @SQL='Select SalepersonFName,City,State,Country,Region into ##Temp from  dbo.TotalSale where '+@ColumnName+'
  in ('''+@Val+''')'
PRINT @SQL
EXECUTE (@SQL)
SELECT * FROM ##Temp
END

--Test your SP for Main Query
EXEC dbo.MainQuery 'Country','Pakistan,India'

Stored Procedure for the Values Parameter ( Cascaded Parameter)

-- Multi Value Parameter 
CreatePROCEDURE dbo.ColValues
  @ColumnName VARCHAR(100)
AS
BEGIN

IF OBJECT_ID('tempdb..##TempValues') ISNOTNULL
DROPTABLE ##TempValues
DECLARE @SQL NVARCHAR(100)
SET @SQL='Select '+@ColumnName+' As val into ##TempValues from dbo.TotalSale'
EXECUTE (@SQL)
SELECTDISTINCT * FROM ##TempValues
END

--Test your SP for Multiple values
EXEC dbo.ColValues 'Country'

Query for ColumnName parameter

--Column Name Parameter Query
SELECT COLUMN_NAME FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_Name='TotalSale'
