5 rows selected.

今天我在测试机器上建立视图，参照ixora的命令生成脚本

select
'create or replace view X_$' || substr(name, 3) ||
' as select * from ' || name || ';'
from
sys.v_$fixed_table
where
name like 'X$%'

我发现有两个无法建立：
create or replace view X_$KMGSCT as select * from X$KMGSCT;

create or replace view X_$KQRFP as select * from X$KQRFP;

报ora-00957 duplicate column name

我执行select * from X$KMGSCT;
发现最后三个字段为lasttime，startime，lasttime_1 ,我猜测lasttime，lasttime_1一定是同一个字段。


X$KQRFP也是遇到相同的问题，这种现象如何解析呢？
