Large object (LOB) data types have the capacity to store large amounts of data. The maximum length of a Teradata LOB is approximately 2GB.

A character large object (CLOB) column can store character data, such as simple text, HTML, or XML documents. A binary large object (BLOB) column can store binary objects, such as graphics, audio and video clips, files, and documents.

You can use UDFs to extend the set of SQL functions that operate on LOBs.
