/** is the representation (mapping) of an SQL

<p>
A SQL
<i>
BLOB
</i>
is a built-in type that stores a
Binary Large Object as a column value in a row of a database table.
The driver implements
<i>
BLOB
</i>
using a
SQL
<code>locator(BLOB)</code>
, which means that a
<code>Blob</code>
object contains a logical pointer to the SQL
<i>
BLOB
</i>
data rather than the data itself.
<br/>
A
<code>Blob</code>
object is valid for the duration of the transaction in which is was created.
</p>
<p>
Methods in the interfaces
<type scope="com::sun::star::sdbc">XResultSet</type>
,
and
<type scope="com::sun::star::sdbc">XPreparedStatement</type>
, such as
<code>getBlob</code>
and
<code>setBlob</code>
allow a programmer to access the SQL
<i>
BLOB
</i>
.
<br/>
The
<code>Blob</code>
interface provides methods for getting the length of a SQL
<i>
BLOB
</i>
(Binary Large Object) value, for materializing a

</i>
value on the client and for determining the position of a pattern of bytes within a
