ORA-14452: 试图创建, 更改或删除正在使用的临时表中的索引
因为表KOL_XX_FIN050_TEMP 为临时表，而且有其他session正在使用。
处理步骤：
1、先从 dba_objects / user_objects中查询到该表的object_id:
select object_id from dba_objects where object_name=upper('KOL_XX_FIN050_TEMP');
2、根据查到的object_id知道使用该表的session：
select * from v$lock where id1=&object_id;
3、在从v$session视图中查到该session的SID和SERIAL#：
select * from v$session where sid=331;
4、杀掉这些进程:
alter system kill session ‘SID,SERIAL#’;
SELECT vs.*
FROM v$session vs
, v$lock vl
, dba_objects obj
WHERE 1 = 1
AND obj.object_id = vl.id1
AND vl.sid = vs.sid
AND obj.object_name = 'KOL_XX_FIN050_TEMP';
