The DBMS_LOB package provides subprograms to operate on, or access and manipulate specific parts of a LOB or complete LOBs.

The DBMS_LOB package applies to both SecureFiles LOB and BasicFiles LOB.

DBMS_LOB Constants Used with SecureFiles LOBs and DBFS and DBMS_LOB Subprograms Used with SecureFiles LOBs and DBFS describe modifications made to the DBMS_LOB constants and subprograms with the addition of SecureFiles LOB and Database File System (DBFS).
