Large objects (LOBs) store large unstructured data such as literals, images, videos, and spatial data. LOB types are categorized into binary large objects (BLOBs) and character large objects (CLOBs).
BLOB
You can store large binary objects such as images and videos in a database as BLOBs and consider them as large bit streams without character set syntax.
For more information, see "LOB data types" in the Developer Guide on the official website of OceanBase Database.
CLOB
You can store single-byte and multi-byte character data as CLOBs. Fixed-width and variable-width character sets are supported and they both use the database character set.
