How do I use a parameter that consist a string in a where statement within a with clause which is bold in the codes. I tried doing that method but its does not work.

I have added a parameter called @param nvarchar(max) already.

SQL

WITH Sales_CTE (SalesPersonID, SalesOrderID, SalesYear)
AS
(
    SELECT SalesPersonID, SalesOrderID, YEAR(OrderDate) AS SalesYear
    FROM Sales.SalesOrderHeader
    WHERE SalesPersonID IN ('+ @param +')
)
SELECT SalesPersonID, COUNT(SalesOrderID) AS TotalSales, SalesYear
FROM Sales_CTE
GROUP BY SalesYear, SalesPersonID

Solution 1

You can use parameters in a WITH clause just like in a traditional statement. The problem in the example is the IN operator which requires a list of values.

Have a look at this tip how you can use a parameter with IN: Using comma separated value parameter strings in SQL IN clauses[^]

Solution 2

you can use dynamic sql and execute it

SQL

DECLARE @SQLQuery AS NVARCHAR(MAX)
SET @SQLQuery = 'SELECT * FROM table1 WHERE EmployeeID in(' + @param +')'
EXECUTE(@SQLQuery)
