Extended Data Types
HCL Informix® enables
you to create extended data types to characterize data that
cannot easily be represented with the built-in data types. (You cannot,
however, use extended data types in distributed transactions that
query external tables.) You can create these categories of extended
data types:
- Complex data types
- Distinct data types
- Opaque data types
Sections that follow provide an overview of each of these data types.
For more information about extended data types, see the IBM® Informix Database Design and Implementation Guide and HCL Informix User-Defined Routines and Data Types Developer's Guide.
