If all registered BLOB or BINARY^* data must be updated when new data is added, or if all BLOB or BINARY^* data must be fetched when data is retrieved, both the server and client must secure large amounts of memory that match the enormous data size. Consequently, the memory resources become used up. The addition update and partial extraction facility for BLOB and BINARY data is used for solving this problem.

^* This refers to BINARY data that has a minimum defined length of 32,001 bytes.

Organization of this subsection

(1) Addition update of BLOB or BINARY data

(2) Partial extraction of BLOB or BINARY data
