Displaying Queries at the Instances Tab

All queries are instances of the class PAL-QUERY. This means you can easily view the list of all queries in a knowledge base at the Instances tab. 

Note: The PAL-QUERY class is part of the pal-query project, which must be included in your project for PAL queries to work. See Enabling PAL Queries and Enabling the PAL Constraints and PAL Queries Tabs for more information.

To view queries at the Instances tab:

1. Click on the Instances tab to select it.
2. If the direct subclasses of :SYSTEM-CLASS are not displayed, click on the icon immediately to the left.
3. If the direct subclasses of :QUERY are not displayed, click on the into immediately to the left.
4. Click on PAL-QUERY.
   The direct instances of PAL-QUERY, which are the queries created in the knowledge base, are displayed in the Direct Instances pane. Clicking on a query displays the PAL Expression Editor for the query in the Instance Form to the right.
