实战：利用Python脚本生成MySQL测试数据

新建一个用户表

drop table if exists tb_user;

create table tb_user(
    id int primary key auto_increment comment '主键',
    name varchar(20) comment '姓名',
    phone varchar(11) comment '手机号',
    profession varchar(50) comment '专业',
    age int comment '年龄',
    status int comment '状态',
    email varchar(50) comment '邮箱'
);

利用Python脚本生成10万条测试数据

# Python >= 3.7.0
# 安装依赖 pip install faker records mysqlclient
from faker import Faker
import records

# 简体中文：zh_CN
faker = Faker(locale="zh_CN")
# 指定随机种子，确保每次生成的数据都是一致的
faker.seed(1)

# 生成数据插入 insert sql
def get_insert_sql(table_name, fields):
    keys = ', '.join([f'`{key}`'.format(key) for key in fields])
    values = ', '.join([f':{key}'.format(key) for key in fields])
    return f'INSERT INTO `{table_name}` ({keys}) VALUES ({values})'

# 获取数据
def get_row():
    return {
        'name': faker.name(),
        'phone': faker.phone_number(),
        'email': faker.email(),
        'age': faker.random_int(20, 30),
        'status': faker.random_int(0, 1),
        'profession': faker.job(),
    }


def main():
    db = records.Database('mysql://root:123456@localhost/data?charset=utf8')

    # 10 * 10000 = 10万条数据
    for i in range(10):
        data = [get_row() for _ in range(1000)]
        sql = get_insert_sql('tb_user', data[0].keys())
        db.bulk_query(sql, data)

if __name__ == '__main__':
    main()
