在建表时创建主键

import mysql.connector
 
mydb = mysql.connector.connect(
  host="localhost",
  user="yourusername",
  passwd="yourpassword",
  database="mydatabase"
)
 
mycursor = mydb.cursor()
 
mycursor.execute("CREATE TABLE customers (id INT AUTO_INCREMENT PRIMARY KEY, name VARCHAR(255), address VARCHAR(255))")
 
#If this page is executed with no error, the table "customers" now has a primary key
