Oracle創建按時間戳分區表

1 建分區表

-- Create table
create table PARTITION_TABLE
(
  field1   INTEGER,
  field2   VARCHAR2(32),
  field3   INTEGER,
)
partition by range(field3)
interval (86400)
(partition p1 values less than (1431964800) ) nologging
tablespace user;
);

2 增加存儲過程對擴展的分區改名

CREATE OR REPLACE PROCEDURE PRO_RENAME_PARTITION AS
  SQLSTR VARCHAR2(4000);
  val2 int;
  newpart varchar2(32);
BEGIN
  for REC in (select table_name
                from user_tables
               where table_name like 'PARTITION_%') loop
    for x in (select high_value, partition_name
                from user_tab_partitions
               where table_name = REC.TABLE_NAME
                 and partition_name not like 'PART_201%') loop
      val2    := to_number(x.high_value);
      newpart := 'PART_' ||
                 to_char(to_date('19700101080000', 'yyyymmddhh24miss') +
                         (val2 - 3600) / 86400,
                         'yyyymmdd');
      sqlstr  := 'alter table ' || REC.TABLE_NAME || ' rename partition ' ||
                 x.partition_name || ' to ' || newpart;
      begin
        execute immediate sqlStr;
      exception
        when others then
          null;
      end;
    end loop;
  end loop;
END PRO_RENAME_PARTITION;

3 增加job定時調用存儲過程

/
begin 
dbms_scheduler.create_job 
( 
job_name => 'job_pro_rename_partition', 
job_type => 'PLSQL_BLOCK', 
job_action => 'begin PRO_RENAME_PARTITION ; end;',
repeat_interval => 'FREQ=DAILY;BYHOUR=1;byminute=0', 
enabled => true
); 
end; 
/
