plsql查询中补入空行做报表分页挺有用

/*这行把查询的结果中和10的倍数差查出来*/
with cnt as (select 10-mod(count(*),10) from scott.emp)
select scott.emp.empno,scott.emp.ename
from scott.emp
union all
select null,null
from all_objects where rownum<=(select * from cnt);
/*引用with子句中需要补的空行数目 */

 

结果：

1 7369 SMITH
2 7499 ALLEN
3 7521 WARD
4 7566 JONES
5 7654 MARTIN
6 7698 BLAKE
