SQL:进行求和查询

Question

有了这个要求:

SELECT c.date, c.temps
FROM portail_cra c
WHERE c.date >=  '2013-06-01'
AND c.date <=  '2013-06-30'
AND c.id_user =  '147'

我有以下结果:

我想把所有领域的"临时"汇总到同一天

例如 :

date         temps
2013-06-03   08:30:00
2013-06-04   03:00:00
etc...

在此先感谢您的帮助!

Answer 1

SELECT c.date, sum(c.temps)
FROM portail_cra c
WHERE c.date >=  '2013-06-01'
AND c.date <=  '2013-06-30'
AND c.id_user =  '147'
GROUP BY c.date
