Python Insert Into Table

插入表

如需填充 MySQL 中的表，请使用 "INSERT INTO" 语句。

在表 "customers" 中插入记录：

import mysql.connector
mydb = mysql.connector.connect(
  host="localhost",
  user="yourusername",
  passwd="yourpassword",
  database="mydatabase"
)
mycursor = mydb.cursor()
sql = "INSERT INTO customers (name, address) VALUES (%s, %s)"
val = ("John", "Highway 21")
mycursor.execute(sql, val)
mydb.commit()
print(mycursor.rowcount, "record inserted.")

重要：请注意语句 mydb.commit()。需要进行更改，否则表不会有任何改变。

插入多行

要在表中插入多行，请使用 executemany() 方法。

executemany() 方法的第二个参数是元组列表，包含要插入的数据：
