哪位高手能告诉小弟我这两个SQL语句有什么区别

SELECT *  FROM (SELECT T.*, ROWNUM ROWNUM_          FROM (SELECT *                  FROM T_LOG_INFO                 WHERE 1 = 1) T         WHERE ROWNUM <= 15510) WHERE ROWNUM_ > 15500?SELECT *  FROM (SELECT T.*, ROWNUM RN          FROM T_LOG_INFO_BUSI T         WHERE ROWNUM < 15510) WHERE RN >= 15500;网上写分页包括hibernate自动分页都是采用上面的语句分页，这两句SQL区别在哪里？
