Python 创建数据表

其实跟 Python 执行 MySQL 事务的操作差不多：

[[email protected] ~]# cat 1.py
#!/usr/bin/env python
import MySQLdb

def connect_mysql():
    db_config = {
        ‘host‘: ‘127.0.0.1‘,
        ‘port‘: 3306,
        ‘user‘: ‘root‘,
        ‘passwd‘: ‘pzk123‘,
        ‘db‘: ‘test‘
    }
    c = MySQLdb.connect(**db_config)
    return c

if __name__ == ‘__main__‘:
    c = connect_mysql()                             # 先连接数据库
    cus = c.cursor()
    sql = ‘‘‘                                       # 定义建表语句
        create table t1(
            id int primary key not null,
            name varchar(10) not null,
            age int not null
        );
    ‘‘‘
    try:
        cus.execute(sql)                            # 创建数据表
        c.commit()
    except Exception as e:
        c.rollback()
        raise e
    finally:
        c.close()

结果如下：

[[email protected] ~]# mysql -uroot -ppzk123 -e "use test; desc t1;"
