1、儲存過程中動態建立表失敗，提示許可權問題，execute immediate 'create global temporary t1 as select * from table1';
 解決：
 1-授權 create any table
 2-儲存過程中加AUTHID CURRENT_USER

2、建立完全域性臨時表資料查詢為空，需要用到臨時表的型別知識，加關鍵字on commit preserve rows即可
   
3、刪除時候遇到問題

失敗：
14452, 00000, "attempt to create, alter or drop an index on temporary table already in use"
// *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.
解決：
truncate後drop
