python-mysql-爲數據庫生成測試數據

測試表

create table single_table (
    id int not null auto_increment,
    key1 varchar(100),
    key2 int,
    key3 varchar(100),
    key_part1 varchar(100),
    key_part2 varchar(100),
    key_part3 varchar(100),
    common_field varchar(100),
    primary key(id),
    key idx_key1 (key1),
    unique key idx_key2 (key2),
    key idx_key3 (key3),
    key idx_key_part(key_part1,key_part2,idx_key3)
) engine=Innodb charset=utf8;
