mysql> create table employee (id int not null primary key,name varchar(100),sharding_id int not null);
mysql>insert into employee(id,name,sharding_id) values(1,'leader us',10000);
mysql>insert into employee(id,name,sharding_id) values(2, 'me',10010);
mysql>insert into employee(id,name,sharding_id) values(3, 'mycat',10000);
mysql>insert into employee(id,name,sharding_id) values(4, 'mydog',10010);

分别到数据DB1,DB2查看，可以看到在DB1中有： 1 leader us 10000 3 mycat 10000 DB2中有： 2 me 10010 4 mydog 10010

这说明分片成功了
