Python：mysql-connector-Python模塊對MySQL數(shù)據(jù)庫進行增刪改查

Mysql文檔：https://dev.Mysql.com/doc/connector-python/en/

PYPI： https://pypi.org/project/mysql-connector-python/

mysql-connector-python 是MySQL官方的Python語言MySQL連接模塊

安裝

$ pip install mysql-connector-python

代碼示例

連接管理

# -*- coding: utf-8 -*- import mysql.connector db_config = { "database": "mydata", "user": "root", "password": "123456", "host": "127.0.0.1", "port": 3306, } # 連接數(shù)據(jù)庫獲取游標，可以設(shè)置返回數(shù)據(jù)的格式，元組，命令元組，字典等... connect = mysql.connector.Connect(**db_config) cursor = connect.cursor(dictionary=True) # 關(guān)閉游標和連接 cursor.close() connect.close()

寫操作

數(shù)據(jù) 寫入 和 更新 都可以使用 execute 和 executemany

刪除就使用execute

寫操作都需要 commit 才會生效

# 插入元組數(shù)據(jù) insert_tuple_sql = "insert into student(name, age) values(%s, %s)" data = ("Tom", 23) cursor.execute(insert_tuple_sql, data) connect.commit() print(cursor.lastrowid) # 一般插入一條時使用，獲取插入id # 插入多條元組數(shù)據(jù) insert_tuple_sql = "insert into student(name, age) values(%s, %s)" data = [ ("Tom", 23), ("Jack", 25), ] cursor.executemany(insert_tuple_sql, data) connect.commit() # 插入字典數(shù)據(jù) insert_dict_sql = "insert into student(name, age) values(%(name)s, %(age)s)" data = { "name": "Tom", "age": 25 } cursor.execute(insert_dict_sql, data) connect.commit() # 插入多條字典數(shù)據(jù) insert_dict_sql = "insert into student(name, age) values(%(name)s, %(age)s)" data = [ { "name": "Tom", "age": 26 }, { "name": "Jack", "age": 27 } ] cursor.executemany(insert_dict_sql, data) connect.commit()

讀操作

cursor.execute("select * from student where name=%s limit 3", ("Tom",)) rows = cursor.fetchall() print(rows) # 因為開始設(shè)置的返回數(shù)據(jù)格式是字典 dictionary ，所以直接返回字典數(shù)據(jù) # [ # {'id': 1, 'name': 'Tom', 'age': 23}, # {'id': 2, 'name': 'Tom', 'age': 23}, # {'id': 3, 'name': 'Tom', 'age': 25} #] # 獲取一些元數(shù)據(jù)信息 print(cursor.column_names) # ('id', 'name', 'age') print(cursor.description) # [ # ('id', 3, None, None, None, None, 0, 16899), # ('name', 253, None, None, None, None, 1, 0), # ('age', 3, None, None, None, None, 1, 0) #] print(cursor.rowcount) # 3 print(cursor.statement) # select * from student where name='Tom' limit 3 print(cursor.with_rows) # True
