sqlwithas排序

1. sql多条件分组查询，求sql语句。

分组是用来聚集汇总的，如求平均、求总和、求最大等
你这个不需要分组，直接排序就可以了

selectname,datefromtableorderbynameasc,datedesc

如果每组要按date的降序排列，也挺简单

with t1 as (select name, max(date) md from table group by name,

t2 as (select table.name name, table.date date, t1.md from table join t1 on table.name=t1.name

order by t1.md)

select name,date from t2
