mysql中,升序为asc,降序为desc。例如:
升序:select * from 表名 order by 表中的字段 asc(mysql中默认是升序排列,可不写)
select * from test order by name asc
select * from test order by name
降序:select * from 表名 order by 表中的字段 desc
select * from test order by name desc
若要进行同时一个升序,一个降序,则如下:
order by 升序字段 asc,降序字段 desc。
select * from test order by name asc,id desc
