Extended Data Types

HCL OneDB™ 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 HCL OneDB Database Design and Implementation Guide and HCL OneDB User-Defined Routines and Data Types Developer's Guide.
