A SQL CLOB is a built-in type that stores a Character Large Object as a column value in a row of a database table. The driver implements a Clob object using a SQL locator(CLOB) , which means that a Clob object contains a logical pointer to the SQL CLOB data rather than the data itself. A Clob object is valid for the duration of the transaction in which it was created.

The Clob interface provides methods for getting the length of a SQL CLOB (Character Large Object) value, for materializing a CLOB value on the client, and for searching for a substring or CLOB object within a CLOB value.

Methods in the interfaces com::sun::star::sdbc::XResultSet , and com::sun::star::sdbc::XPreparedStatement , such as getClob and setClob allow a programmer to access the SQL CLOB .
