Class ClobImpl
java.lang.Object
org.jpox.store.rdbms.datatype.ClobImpl
- All Implemented Interfaces:
- java.sql.Clob
- public class ClobImpl
- extends java.lang.Object
- implements java.sql.Clob
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.
This class is new in the JDBC 2.0 API.
