我试图显示一个付款表的结果，该表包含按天计算的特定列的总和；
payment id | payment_actual_timestamp | payment type | amount
1 | 2015-11-23 13:01:20 | AUTH | 0.16
2 | 2015-11-23 13:07:20 | AUTH | 23.65
3 | 2015-11-24 08:07:20 | VOID | 19.24
4 | 2015-11-24 13:45:20 | AUTH | 0.65
5 | 2015-11-24 16:34:10 | REFUND | 1.20
6 | 2015-11-25 13:07:20 | SETTLE | 4.40
我想展示的是以下内容；
Date | SETTLE | AUTH | VOID | REFUND
2015-11-23 | 0.00 | 23.81| 0.00 | 0.00
2015-11-24 | 0.00 | 0.65 | 19.24| 1.20
2015-11-25 | 4.40 | 0.00 | 0.00 | 0.00
有办法做到这一点吗？
非常感谢。
一个选项是将conditional aggregation与sum和case:一起使用
select date(payment_actual_timestamp),
sum(case when payment_type = 'SETTLE' then amount end) settleamt,
sum(case when payment_type = 'AUTH' then amount end) authamt,
sum(case when payment_type = 'VOID' then amount end) voidamt,
sum(case when payment_type = 'REFUND' then amount end) refundamt
from yourtable
group by date(payment_actual_timestamp)
