/**
 * <P>CallableStatement is used to execute SQL stored procedures.
 *
 * <P>JDBC provides a stored procedure SQL escape that allows stored
 * procedures to be called in a standard way for all RDBMS's. 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 may be used for input,
 * output or both. Parameters are refered to sequentially, by
 * number. The first parameter is 1.
 *
 * <P><CODE>
 * {?= call <procedure-name>[<arg1>,<arg2>, ...]}<BR>
 * {call <procedure-name>[<arg1>,<arg2>, ...]}
 * </CODE>
 *    
 * <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 be processed prior to getting the values of output
 * parameters.
