Extending HCL OneDB™Beyond standard relational database objects, HCL OneDB™ can be extended to handle specialized data types, access methods, routines, and other objects. HCL OneDB™ includes many built-in extensions that are fully integrated in the database server. HCL OneDB™ also provides DataBlade® modules, which are packages of extended database objects for a particular purpose and that are installed separately from the database server. Alternatively, you can create your own user-defined objects for HCL OneDB™.
HCL OneDB™ extensions and DataBlade® modulesThese topics describe how to use built-in database extensions and separately installed DataBlade® modules.
Database Extensions User's GuideThe HCL OneDB™ Database Extensions User's Guide explains how to use the database extensions that come with HCL OneDB™: Large Object Locator, MQ messaging, binary data types, basic text search, node data type, HCL OneDB™ web feature service for Geospatial Data, and SQL packages.
Large object managementThe Large Object Locator extension enables you to create a single consistent interface to large objects. It extends the concept of large objects to include data stored outside the database.

ESQL/C library

ESQL/C library

All Large Object Locator functions except lld_error_raise() and the smart large object functions are implemented as ESQL/C functions, defined in header and library files (lldesql.h and lldesql.so).

Wherever possible, the ESQL/C versions of the Large Object Locator functions avoid server interaction by directly accessing the underlying large object.

See the HCL OneDB™ ESQL/C Programmer's Manual for more information about using the ESQL/C interface to execute Large Object Locator functions.
