------解决方案-------------------- 那不是
select* from tablename
order by bbsanswerbatchid ,bbs…***time ------解决方案-------------------- select *
from tb
order by bbsanswerbatchid ,bbsanswersendtime ------解决方案-------------------- 你这个数据列bbsanswerbatchid就象NEWID()一样,应该是没有相同的数据吧?看你的要求好象没有什么特殊的呢 ------解决方案-------------------- 第一行跟第三个就是重复的,倒数第二个跟倒数第四个也是一样的
应该是个字表,有对应的主表的ID是唯一的吧 ------解决方案--------------------
select bbsanswerbatchid,bbsanswersendtime
from
(
SELECT *,
case when (count(*) over(partition by bbsanswerbatchid)) > 1
then 1
else 0
end as bbsanswerbatchid_flag
FROM tabl
)t
ORDER BY bbsanswerbatchid_flag desc,bbsanswersendtime
------解决方案-------------------- 我试了一下,应该是可以的:
;with tabl(bbsanswerbatchid,bbsanswersendtime)
as
(
select 'abc','2013-01-09' union all
select 'abc','2013-01-10' union all
select 'def','2013-09-01' union all
select 'fgh','2013-09-10'
)
select bbsanswerbatchid,bbsanswersendtime
from
(
SELECT *,
