Set up dynamic queries

You can use a dynamic query to define the data in the database to which a field security policy applies.

You can link a dynamic query to a condition that is applied to a field security policy.

To define a query range, you can use a function.

Create dynamic query with the Wizard

System administrator

You can use a dynamic query to define the data in the database to which a field security policy applies.

You can link a dynamic query to a condition that is applied to a field security policy.

This topic explains how to set up a dynamic query with the Query wizard.
