- * 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.
- *
- * {?= call <procedure-name>[<arg1>,<arg2>, ...]}
- * {call <procedure-name>[<arg1>,<arg2>, ...]}
- *
- *
- * <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

- * CallableStatement is used to execute SQL stored procedures.

- * 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
