IBM® Informix® 12.10

Choosing operator classes for indexes

For most situations, use the default operators that are defined for a secondary-access method. However, when you want to order the data in a different sequence or provide index support for a user-defined data type, you must extend an operator class.

For more information about how to extend an operator class, see IBM® Informix® User-Defined Routines and Data Types Developer's Guide.
