oracle ORA-14452错误处理

create global temporary table on commit preserve rows 用于会话相关,也就在事务结束后truncate data in the temporary table,但如果在会话未结束时要修改temporary table就会出现错误：

ORA-14452: attempt to create, alter or drop an index on temporary table already in use

经查，该错误的解释为：

Cause: An attempt was made to create, alter or drop an index on temporary table which is already in use.

Action: All the sessions using the session-specific temporary table have to truncate table and all the transactions using transaction specific temporary table have to end their transactions.

处理步骤：

1、先从user_objects中查询到该表的object_id:

select object_id from user_objects where object_name=upper('TMP_365100930');

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=181;

4、杀掉这些进程:

alter system kill session SID,SERIAL#;
