我有一个选择一些行的SQL,我希望它也选择我选择的每一行之后的行,我不知道如何编写这样的查询...
简单选择:
SELECT myIndex, scr, date from history where x.state = "Move to Test"
我最近的尝试:
SELECT myIndex, scr, date
from history as x cross join history as y on y.myIndex + 1 = x.myIndex
where state = "Move to Test"
给出:“模糊列名称:myIndex”
如果我要像这样指定列表;
SELECT x.myIndex, x.scr, x.date
from history as x cross join history as y on y.myIndex + 1 = x.myIndex
where x.state = "Move to Test"
我从“ y”表中一无所获...
这是我的输出应如下所示的示例:
391 200024 2006-11-27 16:03:43 Move to Test < I am selecting this row
392 200024 2006-11-27 16:21:02 Dev < I want to also select the *next* row, regardless of what's in it
395 200024 2006-11-29 10:58:17 Move to Test < selected
396 200024 2006-11-29 12:10:29 Peer Review < next
402 200024 2006-11-30 07:27:51 Move to Test < selected
403 200024 2006-11-30 08:26:13 TQA < next
408 200024 2007-05-03 08:35:40 Move to Test < selected
409 200024 2007-05-03 08:52:53 Dev < next
最佳答案
在SQLite 3.8.3或更高版本中:
WITH indexes AS (SELECT myIndex
FROM history
WHERE state = 'Move to Test')
SELECT myIndex,
scr,
date
FROM history
WHERE myIndex IN indexes
OR myIndex - 1 IN indexes
在早期版本中,不能使用CTE:
SELECT myIndex,
scr,
date
FROM history
WHERE myIndex IN (SELECT myIndex FROM history WHERE state = 'Move to Test')
OR myIndex - 1 IN (SELECT myIndex FROM history WHERE state = 'Move to Test')
关于sql - SQLite连接不起作用,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/24091843/
