1 創建一個標準的range分區表:
  SQL>  create table t_partition_range (id number,name varchar2(50))
  2   partition by range(id)(
  3   partition t_range_p1 values less than (10) tablespace tbspart01,
  4   partition t_range_p2 values less than (20) tablespace tbspart02,
  5   partition t_range_p3 values less than (30) tablespace tbspart03,
  6   partition t_range_pmax values less than (maxvalue) tablespace tbspart04
  7   );
Table created
查詢分區表的信息,可以通過查詢user_part_tables,user_tab_partitions 兩個數據字典
user_part_tables:記錄分區表的信息;
user_tab_partitions:記錄表的分區的信息。
例如:
查看分區表的信息:
SQL> select table_name,partitioning_type,partition_count from user_part_tables where
table_name='T_PARTITION_RANGE';
 
TABLE_NAME                     PARTITIONING_TYPE PARTITION_COUNT
------------------------------ ----------------- ---------------
T_PARTITION_RANGE              RANGE                           4
查看表分區的信息:
SQL> select TABLE_NAME,PARTITION_NAME ,HIGH_VALUE ,TABLESPACE_NAME  from user_tab_partitions where 
  2  table_name='T_PARTITION_RANGE';
 
TABLE_NAME                     PARTITION_NAME                 HIGH_VALUE                                    
                                 TABLESPACE_NAME
------------------------------ ------------------------------ ----------------------------------------------
---------------------------------- ------------------------------
T_PARTITION_RANGE              T_RANGE_P1                     10                                            
                                 TBSPART01
T_PARTITION_RANGE              T_RANGE_P2                     20                                            
                                 TBSPART02
T_PARTITION_RANGE              T_RANGE_P3                     30                                            
                                 TBSPART03
T_PARTITION_RANGE              T_RANGE_PMAX                   MAXVALUE
創建global索引range分區:
SQL> create index indx_parti_range_id on t_partition_range(id) global partition by range(id)
  2  (partition i_range_p1 values less than(10) tablespace tbspart01,
  3   partition i_range_p2 values less than(40) tablespace tbspart02,
  4   partition i_range_pmax values less than (maxvalue) tablespace tbspart03
  5  );
Index created
創建global 索引的分區和創建表的分區語句格式完全相同,而且其分區形式與索引所在表的分區形式沒有關聯關係。
查詢索引的分區信息可以通過user_part_indexes,user_ind_partitions 兩個數據字典:
例如:
    SQL> select INDEX_NAME ,table_name,PARTITIONING_TYPE  ,PARTITION_COUNT   from user_part_indexes 
  2  where table_name='T_PARTITION_RANGE' and index_name='INDX_PARTI_RANGE_ID';
 
INDEX_NAME                     TABLE_NAME                     PARTITIONING_TYPE PARTITION_COUNT
------------------------------ ------------------------------ ----------------- ---------------
INDX_PARTI_RANGE_ID            T_PARTITION_RANGE              RANGE                           3
SQL> select INDEX_NAME  ,PARTITION_NAME ,HIGH_VALUE ,TABLESPACE_NAME  from user_ind_partitions
  2  where index_name='INDX_PARTI_RANGE_ID';
 
INDEX_NAME                     PARTITION_NAME                 HIGH_VALUE                                    
                                 TABLESPACE_NAME
------------------------------ ------------------------------ ----------------------------------------------
---------------------------------- ------------------------------
INDX_PARTI_RANGE_ID            I_RANGE_P1                     10                                            
                                 TBSPART01
INDX_PARTI_RANGE_ID            I_RANGE_P2                     40                                            
                                 TBSPART02
INDX_PARTI_RANGE_ID            I_RANGE_PMAX                   MAXVALUE
創建local 分區:
SQL> drop index INDX_PARTI_RANGE_ID;
 
Index dropped
 
SQL> create index INDX_PARTI_RANGE_ID on t_partition_range(id) local;
 
Index created
local索引的分區完全繼承表的分區的屬性,包括分區的類型,分區的範圍值即不需要指定也不能更改,就是前面說的:
local 索引的分區維護完全依賴與其索引所在的表。但是表空間可以不同。測試按照上面的進行。
