<dd>is used to execute SQL stored procedures.
</dd>
<dd><p>
SDBC provides a stored procedure SQL escape that allows stored procedures
to be called in a standard way for all RDBMSs. This escape syntax has one
form that includes a result parameter and one that does not. If used, the
result parameter must be registered as an OUT parameter. The other parameters
can be used for input, output, or both. Parameters are referred to sequentially,
by number. The first parameter is 1.
</p>
<p>
<code>{?=call&lt;procedure-name&gt;[&lt;arg1&gt;,&lt;arg2&gt;,...]}<br/>{call&lt;procedure-name&gt;[&lt;arg1&gt;,&lt;arg2&gt;,...]}
</code>
</p>
<p>
IN parameter values are set using the set methods inherited from
<a href="PreparedStatement.html">PreparedStatement</a>
. The type of all
OUT parameters must be registered prior to executing the stored procedure;
their values are retrieved after execution via the
<code>get</code>
methods
provided by the
<a href="XRow.html">XRow</a>
.
</p>
<p>
A
<code>CallableStatement</code>
can return one
<a href="XResultSet.html">XResultSet</a>
or multiple
<a href="ResultSet.html">ResultSet</a>
objects. Multiple
<code>ResultSet</code>
objects are
handled using operations inherited from
<a href="XPreparedStatement.html">XPreparedStatement</a>
.
</p>
<p>
For maximum portability, a call's
<a href="ResultSet.html">ResultSet</a>
objects and
update counts should be processed prior to getting the values of output
parameters.
