KEY-* 组合分区

创建KEY-HASH二级分区

模板化用法

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

非模板化用法

  PARTITION p2 SUBPARTITIONS 4
)
