Question

我有一段时间生成一份报告，其中包含我的门票创建日期。

这是我的sqlite查询（我直接查询数据库）

.header on
.mode csv
.output opentickets.csv
SELECT DISTINCT
   id AS ticket, summary, status, priority, t.type AS type, 
   owner, time as created

  FROM ticket t, ticket_custom q
  LEFT JOIN enum p ON p.name = t.priority AND p.type = 'priority'
  WHERE t.id = q.ticket AND status <> 'closed'
 ORDER BY  priority, time;

但是我在创作时获得的价值是垃圾：我得到1341324096360000 什么时候得到 2012-07-03

我尝试过unix epoch时间转换... 查询：

.header on
.mode csv
.output opentickets.csv
SELECT DISTINCT
   id AS ticket, summary, status, priority, t.type AS type, 
   owner, datetime(time, 'unixepoch') as created

  FROM ticket t, ticket_custom q
  LEFT JOIN enum p ON p.name = t.priority AND p.type = 'priority'
  WHERE t.id = q.ticket AND status <> 'closed'
 ORDER BY  priority, time;

我得到：-1413-03-01 13:07:12

我错过了什么？

Answer 1

CL是正确的，时间以微秒为单位存储。您可以在schema中看到时间字段为int64，而release notes为.12，表示他们已将时间从“自纪元以来的秒数”更改为“自纪元以来的微秒”

至于我在Trac查询中显示时间的经验，我没有必要进行任何转换。这是一个查询，用于显示过去7天内所有已更改的票证。如您所见，我将票证更改时间显示为select和Trac正确格式化的一部分。 Trac会自动将创建，修改，日期，时间字段格式化为日期和/或时间。有关详细信息，请参阅此Trac wiki page。

    SELECT 
tc.Ticket AS ticket, 
tc.Time as time, 
c.value as  __group__,
ifnull(tc.Newvalue,0) as total,
tc.Author  AS author,         
tc.Field as field     
from ticket_change tc 
LEFT JOIN ticket t on t.id = tc.ticket
LEFT JOIN ticket_custom c on c.ticket = tc.ticket and c.name= 'customer'
LEFT JOIN ticket_custom tt on tt.ticket = tc.ticket and tt.name = 'totalhours'
where field = 'hours' and c.Value is not null
and tc.Time > strftime('%s',CURRENT_DATE-7) +0
and tc.Time < strftime('%s',CURRENT_DATE) +0
and tc.Author = $USER
and tt.value is not null

如果您想要做一些特殊的装饰，请按时SQLite docs查看，但这是一个简单的例子

strftime('%m/%d/%Y', time / 1000000, 'unixepoch', 'localtime')

我希望这会有所帮助。

Answer 2

Unix时间戳以秒为单位，但看起来这些值是微秒：

> SELECT datetime(1341324096360000 / 1000000, 'unixepoch');
2012-07-03 14:01:36
