Results are filtered in a SQL statement using the evaluates to True.

In the next screen (the one shown above) you will see the parameters for the stored procedure and be able to define how their values are obtained.

Regardless of what approach you use, once you specify the parameter values and complete the Sql Data Source wizard, the Sql Data Source will have updated its properties.

This article is one in a series of articles on ASP. However, in Part 2 we only looked at how to retrieve all of the records from a table, view, stored procedure, or ad-hoc SQL query.
