This interface, used only for custom mapping, is used by the driver, and its methods are never directly invoked by a programmer. <p>When an object of a class implementing the interface <code>SQLData</code> is passed as an argument to an SQL statement, the JDBC driver calls the method <code>SQLData.getSQLType</code> to determine the kind of SQL datum being passed to the database. The driver then creates an instance of <code>SQLOutput</code> and passes it to the method <code>SQLData.writeSQL</code>. The method <code>writeSQL</code> in turn calls the appropriate <code>SQLOutput.writeXXX</code> methods to write data from the <code>SQLData</code> object to the <code>SQLOutput</code> output stream as the representation of an SQL user-defined type.<P><DL><DT><B>Since: </B><DD>1.2</DD><DT><B>See Also: </B><DD><a href="package-summary.html#2.0 API">What Is in the JDBC 2.0 API</a></DL><HR><P><!--
