* CallableStatement is used to execute SQL stored procedures.
*
* <p>JDBC provides a stored procedure SQL escape that allows stored

* 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 may be used for input, output or both.
* Parameters are refered to sequentially, by number. The first parameter
* is 1.
*

*
*
* <p>IN parameter values are set using the set methods inherited from
* PreparedStatement. The type of all OUT parameters must be registered
* prior to executing the stored procedure; their values are retrieved
* after execution via the get methods provided here.
*
* <p>A Callable statement may return a ResultSet or multiple ResultSets.
* Multiple ResultSets are handled using operations inherited from
* Statement.
*
* <p>For maximum portability, a call's ResultSets and update counts should
