这个怎么取时间最晚的那一个id,真是越学越回去了！



[解决办法]

SQL code

select top 1 id from tablename order by date desc
[解决办法]

select top 1 id from 表 order by date desc

[解决办法]
select *
from tb
where rowid = 1
order by date desc

？？？ ORACLE不是很懂，建议去ORACLE板块。
[解决办法]
select top 1 id from tablename order by date desc

还有其他列的话还可以使用row_number（）over()实现
[解决办法]
select id from tablename a,(select max(dateT) dateT from tablename) c where a.dateT=c.dateT
