创建HASH-HASH二级分区

模板化用法

CREATE TABLE tb_h_h_tp(
 id bigint not null auto_increment, 
 bid int, 
 name varchar(30),
 birthday datetime not null,
 primary key(id)
) 
PARTITION BY HASH(bid) 
PARTITIONS 2
SUBPARTITION BY HASH(id) 
SUBPARTITIONS 4

非模板化用法

CREATE TABLE tb_h_h_ntp(
 id bigint not null auto_increment, 
 bid int, 
 name varchar(30),
 birthday datetime not null,
 primary key(id)
) 
PARTITION BY HASH(bid) 
PARTITIONS 2
SUBPARTITION BY HASH(id) 
(
  PARTITION p1 SUBPARTITIONS 2,
  PARTITION p2 SUBPARTITIONS 4
)

创建HASH-KEY二级分区

 bid int, 
 name varchar(30),
 birthday datetime not null,
 primary key(id)
) 
PARTITION BY HASH(bid) 
PARTITIONS 4
SUBPARTITION BY KEY(id) 
SUBPARTITIONS 2
