Large Object Locator Data Types

Large Object Locator defines two data types, lld_locator and lld_lob.

You use the lld_locator type to identify the access protocol for a large object and to point to its location. This type is a row type, stored as a row in the database. You can insert, select, delete, and update instances of lld_locator rows in the database using standard SQL INSERT, SELECT, DELETE, and UPDATE statements.

You can also pass an lld_locator row to various Large Object Locator functions. For example, to create, delete, or copy a large object, and to open a large object for reading or writing, you pass an lld_locator row to the appropriate Large Object Locator function. See lld_locator for a detailed description of this data type.

The lld_lob type enables Large Object Locator to reference smart large objects, which are stored as BLOB or CLOB data in the database. The lld_lob type is identical to the BLOB and CLOB types except that, in addition to pointing to the data, it tracks whether the underlying smart large object contains binary or character data.

See lld_lob for a complete description of this data type.
