下面的脚本为新建2014年一年的分区。可根据不同的需求修改下。

sql：

select 'alter table ' || b.table_name || ' add partition PA_' ||
       TO_CHAR(a - 1, 'YYYYMM') ||
       
       ' values less than (TO_DATE( ''' ||
       TO_CHAR(a, 'YYYY-MM-DD HH24:MI:SS') || ''',''YYYY-MM-DD HH24:MI:SS'');'

  from (select add_months(trunc(DATE '2014-01-01', 'month'), level) a
          from dual
        connect by level < 13),
       (select owner || '.' || table_name table_name
          from dba_tables
         where table_name in ('T_WCP_FRZ_CREDENTIAL', 'T_WCP_ACCT_QUERY_CREDENTIAL')) b
union all
select 'alter table ' || c.owner||'.'||c.table_name
        ||
       ' add partition PA_MAX values less than (MAXVALUE);'
       
  from dual,(select owner, table_name
          from dba_tables
         where table_name in ('T_WCP_FRZ_CREDENTIAL','T_WCP_ACCT_QUERY_CREDENTIAL')) c

 order by 1

 

执行的结果：

附件一个查找数据库中range分区的分区表（我们系统基本是时间的range分区，查找出来的表还需仔细核对，防止出现误执行）：

select OWNER, TABLE_NAME
  from dba_part_tables c
 where c.partitioning_type = 'RANGE'
   and table_name not like 'BIN$%'
   and owner not in ('SYS',
                     'SYSTEM',
                     'DBSNMP',
                     'SYSMAN',
                     'OUTLN',
                     'MDSYS',
