Selection using CQL

You can define a selection using Common Query Langague (similar to an SQL where statement):

Select a layer with feature content in the Layer View
Open the Table View
From the list of available attributes go to the bottom of the list and choose: CQL
Type in a filer:
- COLOR_MAP=3 OR COLOR_MAP=2
- NAME like '%Gulch%' AND DESIG = 'valley'

population > 30000	population attribute greater than 30000
age BETWEEN 20 AND 30	age between 20 and thirty
