Overview of CLOB (Character Large Object)

This section describes what are CLOB (Character Large Object) data types and how to work with them.

CLOB (Character Large Object) is a large collection of character data stored in a database table. Different database servers handles CLOB differently. But there are some common characteristics like:

JDBC offers an interface, java.sql.Clob, to allow JDBC driver to provide generic functionalities to handle CLOB data in the database.

CLOB data can also be handled as character strings with the java.lang.String class.

CLOB data can also be handled as character streams with the java.io.Reader class.
