pymysql中如何将动态的插入数据库中

Posted 2021-01-09 zengsf

data = {
    ‘id‘: ‘1‘,
    ‘name‘: ‘zengsf‘,
    ‘age‘: 20
}
table = ‘students‘
#获取到一个以键且为逗号分隔的字符串，返回一个字符串
keys = ‘, ‘.join(data.keys())
values = ‘, ‘.join([‘%s‘] * len(data))
sql = ‘INSERT INTO {table}({keys}) VALUES ({values})‘.format(table=table, keys=keys, values=values)
try:
    #这里的第二个参数传入的要是一个元组
   if cursor.execute(sql, tuple(data.values())):
       print(‘Successful‘)
       db.commit()
except:
    print(‘Failed‘)
    db.rollback()
db.close()
