Building and Using Queries
Learn how to use queries to
manipulate your project materials (raster, vector, CAD, TIN, or databases)
according to the geoattributes attached to their elements. Queries control
which elements in a geodata layer are selected, and how they are
displayed, printed in maps, or used in other analytical procedures. Begin
with simple one-line expressions and progress towards longer, complex
queries that evaluate geoattributes from multiple related tables and
objects.
