Large Object Locator Support

A LOB locator contains a logical pointer to LOB data in Adaptive Server rather than the data itself, thereby reducing the amount of data that passes through the network between Adaptive Server and its clients.

Adaptive Server 15.7 includes Transact-SQL commands and functions that operate on LOB data using LOB locators. You can invoke these commands and functions as language commands from the Client-Library. See Chapter 21, "In-Row Off-Row LOB" in the Adaptive Server Enterprise Transact-SQL Users Guide.

• Client-Library Changes
  The CS_LOCATOR datatype supports LOB locator. The cs_locator_alloc() and cs_locator_drop() APIs allocate and deallocate memory for CS_LOCATOR variables. cs_locator() has been added to retrieve information from a CS_LOCATOR variable.
• Open Server Support for Large Object Locators
  LOB locator functionality has been added to Server-Library, allowing Open Server applications to pass LOB locator language commands from the client to back-end servers.
• Large Object Locator Support
  These connection capabilities indicate support for sending and receiving LOB locators.
