1. 我的脚本

import pymysql


sql = """
update BaseInfo_dailyinfo_temp set open=26.88,close=32.86,high=32.86,low=26.88,exchange_rate=21.83,data_date='2021-07-05',exchange_amount=715182688.0,
exchange_quantity=231947,price_change_amount=5.48,price_change_rate=20.01,update_time='2021-07-05 15:37:34' where code_id=1234;
update BaseInfo_dailyinfo_temp set open=19.11,close=21.6,high=21.6,low=18.51,exchange_rate=26.22,data_date='2021-07-05',exchange_amount=1309556816.0,
exchange_quantity=655858,price_change_amount=3.6,price_change_rate=20.0,update_time='2021-07-05 15:37:34' where code_id=352;
"""


conn = pymysql.Connect(user='root', password='123', host='127.0.0.1', db='stockAnalysis', port=3306)
cur = conn.cursor()

cur.execute(sql)
conn.commit()

2. 报错截图

1. 

 

 

 

3. 原因及解决方法

1. pymysql在0.8版本以前（不包含0.8）是默认可以同时执行多条sql语句的，但是在0.8之后不再设置为默认，需要手动配置
2. 配置方法是在获取数据连接时，配置参数
client_flag=CLIENT.MULTI_STATEMENTS

4. 更改后的代码

import pymysql
-- 导入模块
from pymysql.constants import CLIENT


sql = """

update BaseInfo_dailyinfo_temp set open=26.88,close=32.86,high=32.86,low=26.88,exchange_rate=21.83,data_date='2021-07-05',exchange_amount=715182688.0,
exchange_quantity=231947,price_change_amount=5.48,price_change_rate=20.01,update_time='2021-07-05 15:37:34' where code_id=1234;

conn = pymysql.Connect(user='root', password='123', host='127.0.0.1', db='stockAnalysis', port=3306, client_flag=CLIENT.MULTI_STATEMENTS)  # 添加client_flag参数

cur = conn.cursor() cur.execute(sql) conn.commit()
