Python開發【筆記】：pymsyql 插入一條數據同時獲取新插數據的自增id的兩種方式

一、通過cursor.lastrowid

import pymysql.cursors

# Connect to the database

connection = pymysql.connect(host='192.168.90.10',
                             port=3306,
                             user='remote',
                             password='123456',
                             db='Jefrey',
                             charset='utf8mb4',
                             cursorclass=pymysql.cursors.DictCursor,
                             autocommit = True)

try:

    with connection.cursor() as cursor:  # 增加
        sql = "INSERT INTO `users` (`email`, `password`) VALUES (%s, %s)"
        cursor.execute(sql, ('[e-mail]', 'very-secret'))
        print(cursor.lastrowid)
finally:
    connection.close()

# 87

 

二、通過sql語句SELECT LAST_INSERT_ID()

import pymysql.cursors

# Connect to the database

connection = pymysql.connect(host='192.168.90.10',
                             port=3306,
                             user='remote',
                             password='123456',
                             db='Jefrey',
                             charset='utf8mb4',
                             cursorclass=pymysql.cursors.DictCursor,
                             autocommit = True)

try:

    with connection.cursor() as cursor:  # 增加
        sql = "INSERT INTO `users` (`email`, `password`) VALUES (%s, %s)"
        cursor.execute(sql, ('[e-mail]', 'very-secret'))
        sql = 'SELECT LAST_INSERT_ID() AS id;'
        cursor.execute(sql)
        database = cursor.fetchone()
        print(database)
finally:
    connection.close()

# {'id': 88}
