create global temporary table on commit preserve rows 用于會話相關(guān),也就在事務(wù)結(jié)束后truncate data in the temporary table,但如果在會話未結(jié)束時(shí)要修改temporary table就會出現(xiàn)錯(cuò)誤：

ORA-14452: attempt to create, alter or drop an index on temporary table already in use
經(jīng)查，該錯(cuò)誤的解釋為：
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.

處理步驟：
1、先從user_objects中查詢到該表的object_id:
select object_id from user_objects where object_name=upper('TMP_365100930');

2、根據(jù)查到的object_id知道使用該表的session：
select * from v$lock where id1=&object_id;

3、在從v$session視圖中查到該session的SID和SERIAL#：
select * from v$session where sid=181;

4、殺掉這些進(jìn)程:
alter system kill session SID,SERIAL#;

總結(jié)
