How to pass a multi-value parameter to a query

This example illustrates a workaround to use multi-value parameters in a query string.

At present, query parameters cannot be directly mapped to multi-value report parameters, and this task is solved by adding a WHERE clause to the SQL string in the following way.

[SQL]
SELECT [Categories].[CategoryID], [Categories].[CategoryName] FROM [Categories] [Categories]
WHERE [Categories].[CategoryID] IN (1,2,3)

This example illustrates how to dynamically update the query string using values assigned to a report parameter.
