Extensions to Dynamic Server

The IBM Informix Large Object Locator DataBlade module provides new data types and functions to extend your database server.

The lld_locator data type is a row data type that contains the access protocol for a smart large object and a pointer to its location. The lld_lob data type is an opaque data type that is identical to the BLOB and CLOB data types, except that in addition to pointing to the data, it tracks whether the underlying smart large object contains binary or character data. It is contained in the lld_locator data type as a field in the row.

The IBM Informix Large Object Locator DataBlade module provides basic functions for creating, opening, closing, deleting, reading from, and writing to smart large objects; client functions to process client files; utility functions for raising errors; and functions for copying smart large objects.

Most of the IBM Informix Large Object Locator DataBlade module functions are implemented in an API library, an ESQL/C library, and an SQL interface for maximum programming flexibility.
