早上好,
我遇到了查询问题。我试图在UTC时间范围内对列进行求和。当我仅使用确切的UTC值查询源表时,它正在按预期工作。一旦我添加了一个连接,一个调度表添加了一些结果不正确的详细信息。下面是我正在使用的查询和表结构。任何帮助将不胜感激。
查询1:
select logid,SUM(ti_availtime) as "Total Avail TIme"
from status
where logid = 12345
and status.starttime_utc
between 1528070400 and 1528102800
group by logid
logid Total Avail Time
12345 20106
状态表的表结构:
Date Logid Starttime_utc Ti_availtime Interval
2018-06-04 12345 1528070400 106 30
2018-06-04 12345 1528070401 5000 30
2018-06-04 12345 1528070402 5000 30
2018-06-04 12345 1528102800 10000 30
注意:UTC值(1528070401,1528070402)只是示例*
时间表的表格结构:
Date Logid Name Starttime_utc Stoptime_utc
2018-06-04 12345 John Smith 1528070400 1528102800
查询2:
select schedule.Analyst, SUM(status.ti_availtime)
from status
join schedule on status.logid = schedule.logid
where schedule.logid = 30120 and status.starttime_utc between schedule.starttime_utc and schedule.starttime_utc
group by vqschedule.row_date
结果:
Analyst Total Avail Time
John Smith 1351027
答案 0 :(得分:2)
完全同意@jspcal,在第一个查询中还有一件事是你在第二个项目进度计划中运行status.logid。分析,我只是写完整的查询
select status.logid, SUM(status.ti_availtime)
from status
join schedule on status.logid = schedule.logid
where schedule.logid = 30120 and status.starttime_utc between schedule.starttime_utc and schedule.stoptime_utc
group by status.logid
答案 1 :(得分:0)
第一个查询按status.logid
分组,而第二个分组按schedule.row_date
分组。如果在结束时引用schedule.stoptime_utc
:
status.starttime_utc between schedule.starttime_utc and schedule.starttime_utc
