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
XResultSet
,
and
XPreparedStatement
, such as
getClob
and
setClob
allow a programmer to
access the SQL
CLOB
.
