（SQL Server 2008）我正在尝试从工厂计时系统中过滤出人工记录。这是下面的数据示例。TCODE列具有“ O”（接通时间）或具有“ OF”（断开时间）。例如，CHAVEZ处理序列50（即kitpull）的时间为1.06小时。
问题：当一个工人完成两次以上的刷卡作业后，系统会自动添加一对我需要删除的记录（0小时）。如果是顺序50拉力套件和顺序400沉孔，则只有两次滑动（先打开再关闭），因此没有多余的记录。但是，每个其他序列都有两个尾随的额外行。在序列100的情况下，TTIME = 93724（09:37:24 AM）的最后两行是多余的行。您可以看到最后一行的完整代码为1，正式标志着作业序列已完成。

我最初开始在最里面的子查询中添加一个行号，以便稍后可以像这样引用MAX（rn）：
SELECT
*,
ROW_NUMBER() OVER (ORDER by TTIME) rn
FROM
MySmallData
从上面的子查询中，我希望从原始数据中选择所有记录，以除去“ CompleteCode中带有1的行和右上方的行”。
这更多是策略问题，而不是语法问题。我希望有一些建议。
谢谢， 约翰

我认为您可以使用exists来做到这一点：
select msd.*
from mysmalldata msd
where not ((msd.completecode is null and
exists (select 1
from mysmalldata msd2
where msd2.MFGORDNO = msd.MFGORDNO and
msd2.sequence = msd.sequence and
msd2.badge = msd.badge and
msd2.ttime = msd.ttime and
msd2.completecode = 1
)
) or
(coalesce(msd.completecode, -1) = 1 and
exists (select 1
from mysmalldata msd2
where msd2.MFGORDNO = msd.MFGORDNO and
msd2.sequence = msd.sequence and
msd2.badge = msd.badge and
msd2.ttime = msd.ttime and
msd2.completecode is null
)
)
);

开始处理我自己的版本，想到“不，请与@ Gordon's一起去，他怎么做的”，遇到了一些问题，因此选择了（+1）并对其进行了一些修改：
SELECT msd.*
from mysmalldata msd
where msd.completecode = 0 -- All "completeCode=0" rows are accepted
or (-- All "NULL" rows for which there is no matching "completeCode=1" row are accepted
msd.completecode is null
and not exists (select 1
from mysmalldata msd2
where msd2.MFGORDNO = msd.MFGORDNO
and msd2.sequence = msd.sequence
and msd2.badge = msd.badge
and msd2.ttime = msd.ttime
and msd2.completecode = 1
)
)
-- Note that no "completeCode=1" rows are accepted
