41/** is the mapping for the SQL
42	<code>CLOB</code>
43	type.
44
45
46	<p>
47	A SQL
48	<code>CLOB</code>
49	is a built-in type
50	that stores a Character Large Object as a column value in a row of
51	a database table.
52	The driver implements a
53	<code>Clob</code>
54	object using a SQL
55	<code>locator(CLOB)</code>
56	, which means that a
57	<code>Clob</code>
58	object
59	contains a logical pointer to the SQL
60	<code>CLOB</code>
61	data rather than
62	the data itself. A
63	<code>Clob</code>
64	object is valid for the duration
65	of the transaction in which it was created.
66	</p>
67	<p>
68	The
69	<code>Clob</code>
70	interface provides methods for getting the
71	length of a SQL
72	<code>CLOB</code>
73	(Character Large Object) value,
74	for materializing a
75	<code>CLOB</code>
76	value on the client, and for
77	searching for a substring or
78	<code>CLOB</code>
79	object within a
80	<code>CLOB</code>
81	value.
82	</p>
83	<p>
84	Methods in the interfaces
85	<type scope="com::sun::star::sdbc">XResultSet</type>
86	,
87	and
88	<type scope="com::sun::star::sdbc">XPreparedStatement</type>
89	, such as
90	<code>getClob</code>
91	and
92	<code>setClob</code>
93	allow a programmer to
94	access the SQL
95	<code>CLOB</code>
96	.
