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.
SQL Packages ExtensionThe SQL packages extension provides SPL routines that you can use in an application that is compatible with database servers other than HCL OneDB™.
DBMS_LOB packageThe DBMS_LOB package provides the capability to operate on large objects.
WRITE procedures The WRITE procedures provide the capability to write data into a large object.

WRITE procedures

The WRITE procedures provide the capability to write data into a large object.

Any existing data in the large object at the specified offset for the given length is overwritten by data given in the buffer.

Syntax

lob_loc: An input or output argument of type BLOB(10M) or CLOB(10M) that specifies the large object locator of the large object to be written.
amount: An input argument of type INTEGER that specifies the number of bytes or characters in buffer to be written to the large object.
offset: An input argument of type INTEGER that specifies the offset in bytes or characters from the beginning of the large object for the write operation to begin. The start value of the large object is 1.
buffer: An input argument of type BLOB(32767) or VARCHAR(32672) that contains the data to be written to the large object. If lob_loc is a BLOB, then buffer must be BLOB. If lob_loc is a CLOB, then buffer must be VARCHAR.
