The mapping in the JavaTM programming language
for the SQL CLOB type.
An SQL CLOB is a built-in type
that stores a Character Large Object as a column value in a row of
a database table.
By default drivers implement a Clob object using an 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 an 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 ResultSet ,
CallableStatement , and PreparedStatement , such as
getClob and setClob allow a programmer to
access an SQL CLOB value. In addition, this interface
has methods for updating a CLOB value.
All methods on the Clob interface must be fully implemented if the
JDBC driver supports the data type.
