Tutorial: Using a Dynamic Query in a Report
This advanced tutorial is designed to help you understand how you can use dynamic queries in report design. In this tutorial, you will create a project, create two datasets, add a table and parameters, and alter one of the queries to use a dynamic query.
The report in this tutorial contains a table that lists all employees for a particular department, or all employees in the company, depending on a parameter value. The query used by the table will change dynamically through an expression. Although a static query can filter employees through a query parameter, it cannot alter the structure of the query (in this case, remove the WHERE clause in order to display all employees). A dynamic, expression-based query can.
This tutorial requires that you use the generic query designer to create the queries. The generic query designer is the default query design tool for SQL Server data sources. The generic query designer is enabled when you toggle the generic query designer button on the Report Designer toolbar:
