記一次Oracle的分區表建立

--查看分區記錄
select * from dba_tab_partitions where table_name='TB_LOAN_ACCOUNT_CON';

--查看分區表下有多少個分區
select table_name,count(*) from dba_tab_partitions group by table_name order by 2 desc;

--我的業務創建分區表 -- 在線重定義
--查看該表是否可以進行在線重定義
execute dbms_redefinition.can_redef_table('SCMS_CON','TB_LOAN_ACCOUNT_CON');
--grant all on SYS.DBMS_REDEFINITION to SCMS_CON;
--grant create any table,alter any table,drop any table,lock any table,select any table to scms_con;
-- Create table
create table TB_LOAN_ACCOUNT_CON_BAK

--在見表後緊接着應該是建立需要的索引?  暫不確定  建立完成之後也可進行建立索引的操作吧?!
