我需要你的帮助。我想在列中对值进行排序,然后保存更改。但我不知道该怎么做。 表看起来像这样:
Date | DocNumber
-----------------------------
2018-15-04 | 1
2018-15-07 | 2
2018-15-08 | 3
2018-15-06 | 4
2018-15-05 | 5
我希望得到类似的东西:
Date | DocNumber
-----------------------------
2018-15-04 | 1
2018-15-05 | 2
2018-15-06 | 3
2018-15-07 | 4
2018-15-08 | 5
所以我需要对“DocNumber”和“Date”列进行排序。 请帮忙。

不建议在每列中单独对值进行排序。但是,它可以做到。这是一种方法:
select max(date) as date, max(docnumber) as docnumber
from ((select row_number() over (order by date) as seqnum, date, NULL as docnumber
from t
) union all
(select row_number() over (order by docnumber) as seqnum, NULL, docnumber
from t
)
) dd
group by seqnum
order by seqnum;
