我有个问题。。
假设我有这张桌子。。。
waktu | tglTransaksiJual | nominal | ongkir | STATUS | idUser
---------------------------------------------------------------------------------------
2013-02-01 00:00:00 | 2013-01-29 15:00:00 | 10000 | 10000 | APPROVED | 1
0000-00-00 00:00:00 | 2013-02-02 15:00:00 | 20000 | 0 | DONE | 2
0000-00-00 00:00:00 | 2013-02-02 15:00:00 | 10000 | 5000 | DONE | 2
2013-02-03 00:00:00 | 2013-02-01 15:00:00 | 20000 | 0 | APPROVED | 3
我用这个查询
SELECT DISTINCT(date(IF(waktu = '0000-00-00 00:00:00', tglTransaksiJual, waktu))) AS thedate, SUM( nominal+ongkir ) AS total
FROM transaksijual
WHERE IF(waktu = '0000-00-00 00:00:00', tglTransaksiJual, waktu) BETWEEN '2013-02-01' AND '2013-02-05' AND status LIKE 'DONE%' AND idUser LIKE '2%'
GROUP BY thedate
ORDER BY thedate ASC
但我得到的结果是
thedate | total
-------------------
2013-02-01 | 30000
我想要的就是这样
thedate | total
------------------
2013-02-01 | 0
2013-02-02 | 35000
2013-02-03 | 0
我该怎么做?有可能吗??
所以结论是。。当没有数据时,我想得到0个值并得到行。。。
最佳答案
删除WHERE
条件并将SUM
列更新为仅在满足条件时求和:
SUM(IF(status = 'DONE' AND idUser = '2', nominal + ongkir, 0))
