-在使用rownum对结果集编号的查询过程中不要使用rownum做>1以上数字的判断,否则查询不到任何数据.先编号再查询. -SELECT * FROM(SELECT rownum rn, ename,job FROM EMP_XWBING) WHERE rn BETWEEN 6 AND 10; - -若对查询内容有排序需求时,要先进行排序操作. -取公司工资排名的6-10? -SELECT * -FROM(SELECT rownum rn,t.* - FROM(SELECT ename,sal,job - FROM emp_xwbing - ORDER BY sal DESC)t - WHERE rownum<=10) -WHERE rn >5;
