executeBatch方法详解3

 * A driver is not required to implement this method.
     * The possible implementations and return values have been modified in
     * the Java 2 SDK, Standard Edition, version 1.3 to
     * accommodate the option of continuing to proccess commands in a batch
     * update after a <code>BatchUpdateException</code> obejct has been thrown.
       驱动不实现此方法，可能会出现的实现和返回值在Java 2 SDK，Standard Edition,
       version 1.3 ，以适应批处理时抛出BatchUpdateException 异常后是继续执行还是
       终止执行的选项。
      
     * @return an array of update counts containing one element for each
     * command in the batch.  The elements of the array are ordered according
     * to the order in which commands were added to the batch.
       返回一个和添加命令时的顺序一样的数组结果
     * @exception SQLException if a database access error occurs or the
     * driver does not support batch statements. Throws {@link BatchUpdateException}
     * (a subclass of <code>SQLException</code>) if one of the commands sent to the
     * database fails to execute properly or attempts to return a result set.
     * @since 1.3

       如果数据库访问异常或驱动不支持批处理命令，或者如果一个命令发送到数据库时失败或尝试取得结果集
       时失败，都会抛一个异常BatchUpdateException 它是SQLException的子类。
