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.
