mysql 爲現有表建立範圍分區

爲某列進行分區。範圍這邊自己定義

ALTER TABLE ts partition by RANGE(id)
(

 PARTITION p9 VALUES LESS THAN (10000) ,
 PARTITION p10 VALUES LESS THAN (20000) ,
 PARTITION p11 VALUES LESS THAN MAXVALUE 
)

查看建立的分區

 

SELECT
  partition_name part, 
  partition_expression expr, 
  partition_description descr, 
  table_rows 
FROM
  INFORMATION_SCHEMA.partitions 
WHERE
  TABLE_SCHEMA = SCHEMA() 
  AND TABLE_NAME='ts'

 

 

 

查詢某一分區下的數據

select * from ts partition(p10);
