[/color]select distinct userid,username,password
[color=red]from t_user
where registDate is like '%2012%'
order by registDate
报：ORA-01791：不是SELECTed 表达式 错误
改为：
select userid,username,password
from (
select distinct userid,username,password
from t_user
)
where rigistDate is like '%2012%'
order by[color=red][/color] rigistDate
报 ORA-00904：'RIGISTDATE' 无效的标示符
原因：查出的列中没有：rigistDate
加入后即可
如下
select userid ,username,password,rigistDate
from(
select userid,username,password,rigistDAte
from t_user
)
where rigistDate like '%2012%'
order by rigistDate
不是SELECTed表达式
