如何使用Python Mysql向sql中新插入的列添加值？

Question

我在向新添加的列插入值时遇到错误。

import mysql.connector
mydb = mysql.connector.connect(
    host = 'localhost',
    username = 'rt',
    password = 'rt',
    database = 'demo'
)
mycursor = mydb.cursor()
sql = "INSERT INTO customers_1 (Address) VALUES(%s)"
val = ("Karthik")
mycursor.execute(sql,val)
mydb.commit()
print(mycursor.rowcount, "record inserted.")

Answer 1

您是否正在尝试更新所有条目的列？

UPDATE customers_1
SET Address = %s
WHERE condition;
