Group By Rollup(A.IS_QUITWORK)
Order By Decode(A.IS_QUITWORK, Null, 0)
GROUPTYPE PSNCOUNT
1 合计 0
2 在职 1658
3 退休 6012
其中合计行为0，应为7669，怎么修改SQL语句，谢谢！！！
------解决方案--------------------
提供一个思路
----------------------------------------------
with tmp as (
select '1' IS_QUITWORK, 1 ID_CARD from dual
union all
select '2',1 from dual
union all
select '1',2 from dual
union all
select '1',3 from dual
union all
select '1',1 from dual
)
select Decode(IS_QUITWORK, '1', '在职', '2', '退休', '合计') As GROUPTYPE,
count(distinct IS_QUITWORK||to_char(ID_CARD))
from tmp
group by
cube(IS_QUITWORK)
order by grouping_id(IS_QUITWORK) asc
GROUPTYPE PSNCOUNT
--------- ----------
在职 3
退休 1
合计 4
3 rows selected.
------解决方案--------------------
SELECT DECODE (A.IS_QUITWORK, '1', '在职', '2', '退休', '合计') GROUPTYPE,
COUNT (1) PSNCOUNT
FROM M_ZF_COMBINATION_STAT_SUMMARY a, V_M_ZF_COMBINATION_STAT c
WHERE A.IS_QUITWORK = C.IS_QUITWORK
AND C.ST_DATE >= '20040901'
AND C.ST_DATE <= '20040902'
AND A.ST_DATE >= '20040901'
AND A.ST_DATE <= '20040902'
GROUP BY ROLLUP (A.IS_QUITWORK)
关联没错的话，就没有问题
