SELECT * FROM (SELECT e.*,ROWNUM row_num FROM (SELECT emp_no,emp_name,dob from emp) outr WHERE ROWNUM < ( (pagenum * row_size) + 1)) WHERE row_num >= ( ( (pagenum - 1) * row_size) + 1)
我想在同一个查询中得到行数,为此我尝试过运用
COUNT(*) OVER ()
但是当我分页到下一组页面和行时,我得不到准确的结果.
如何有效地使用COUNT(*)OVER()？
SELECT * FROM (SELECT outr.*,dob,count(*) over () total_nb FROM emp ORDER BY ...) outr WHERE ROWNUM < ((pagenum * row_size) + 1)) WHERE row_num >= (((pagenum - 1) * row_size) + 1)
不要忘记ORDER BY.
