Large object data types (LOB) are used to store large and unstructured data, such as text, images, video, and spatial data. LOB data types include BLOB and CLOB.
Applicability
This topic applies only to OceanBase Database Enterprise Edition. OceanBase Database Community Edition provides only MySQL-compatible mode.
BLOB
Used to store large binary objects in the database. It can be considered as a bit stream without character set semantics, such as images and video.
CLOB
Used to store single-byte and multibyte character data. It supports both fixed-width and variable-width character sets, and both use the database character set.
