/**
 * The interface used to execute SQL stored procedures.  The JDBC API 
 * provides a stored procedure SQL escape syntax 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, with the first parameter being 1.
 * <PRE>

 *   {call &lt;procedure-name&gt;[(&lt;arg1&gt;,&lt;arg2&gt;, ...)]}
 * </PRE>
 * <P>
 * IN parameter values are set using the <code>set</code> methods inherited from
 * {@link PreparedStatement}.  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 here.
 * <P>
 * A <code>CallableStatement</code> can return one {@link ResultSet} object or 
 * multiple <code>ResultSet</code> objects.  Multiple 
 * <code>ResultSet</code> objects are handled using operations
 * inherited from {@link Statement}.
 * <P>
 * For maximum portability, a call's <code>ResultSet</code> objects and 
 * update counts should be processed prior to getting the values of output
 * parameters.
