Techopedia explains Character Large Object (CLOB)
A character large object, also known as a CLOB, is similar
to a binary large object (BLOB) in that they are both large amounts of data.
The key difference is that a CLOB is stored using a text encoding method such
as ASCII or Unicode. CLOBs are supported in Oracle and IBM DB2, though some
databases cannot use certain commands such as “LIKE” on CLOBs. Other databases
support text, memo or long character fields. CLOBs can encompass long documents
such as books. They can range up to two gigabytes in size or even more. Some
databases store CLOBs by referencing out-of-table data.
