|
<div><p>When using Java™ to write stored procedures, you can
|
|
use two possible parameter passing styles.</p>
|
|
<p>The recommended style is the <a href="javaparm.htm">JAVA parameter
|
|
style</a>, which matches the parameter style specified in the SQLj: SQL
|
|
routines standard. The second style, <a href="db2genpm.htm">DB2GENERAL</a>,
|
|
is a parameter style defined by DB2<sup>®</sup> UDB. The parameter style also determines
|
|
the conventions that you must use when coding a Java stored procedure.</p>
|
|
<p>Additionally, you should also be aware of some <a href="javarest.htm">restrictions</a>
|
|
that are placed on Java stored procedures.</p>
