Python访问MySQL封装的常用类实例
本文实例讲述了Python访问MySQL封装的常用类。分享给大家供大家参考。具体如下:
python访问mysql比较简单,下面整理的就是一个很简单的Python访问MySQL数据库类。
自己平时也就用到两个mysql函数:查询和更新,下面是自己常用的函数的封装,大家拷贝过去直接可以使用。
文件名:DBUtil.py

封装的mysql常用函数
'''
import MySQLdb
class DB():
def __init__(self, DB_HOST, DB_PORT, DB_USER, DB_PWD, DB_NAME):
self.DB_HOST = DB_HOST
self.DB_PORT = DB_PORT
self.DB_USER = DB_USER
self.DB_PWD = DB_PWD
self.DB_NAME = DB_NAME
self.conn = self.getConnection()
def getConnection(self):
return MySQLdb.Connect(
host=self.DB_HOST, #设置MYSQL地址
port=self.DB_PORT, #设置端口号
user=self.DB_USER, #设置用户名
passwd=self.DB_PWD, #设置密码
db=self.DB_NAME, #数据库名
charset='utf8' #设置编码
)
def query(self, sqlString):
cursor=self.conn.cursor()
cursor.execute(sqlString)
returnData=cursor.fetchall()
cursor.close()
self.conn.close()
return returnData
def update(self, sqlString):
cursor=self.conn.cursor()
cursor.execute(sqlString)
self.conn.commit()
cursor.close()
self.conn.close()
if __name__=="__main__":
db=DB('127.0.0.1',3306,'root','','wordpress')
print db.query("show tables;")
使用方法为文件下面的main函数,使用query执行select语句并获取结果;或者使用update进行insert、delete等操作。
希望本文所述对大家的Python程序设计有所帮助。

MySQL and phpMyAdmin are powerful database management tools. 1) MySQL is used to create databases and tables, and to execute DML and SQL queries. 2) phpMyAdmin provides an intuitive interface for database management, table structure management, data operations and user permission management.

In MySQL, the function of foreign keys is to establish the relationship between tables and ensure the consistency and integrity of the data. Foreign keys maintain the effectiveness of data through reference integrity checks and cascading operations. Pay attention to performance optimization and avoid common errors when using them.

Both Python and JavaScript's choices in development environments are important. 1) Python's development environment includes PyCharm, JupyterNotebook and Anaconda, which are suitable for data science and rapid prototyping. 2) The development environment of JavaScript includes Node.js, VSCode and Webpack, which are suitable for front-end and back-end development. Choosing the right tools according to project needs can improve development efficiency and project success rate.

Python and C each have their own advantages, and the choice should be based on project requirements. 1) Python is suitable for rapid development and data processing due to its concise syntax and dynamic typing. 2)C is suitable for high performance and system programming due to its static typing and manual memory management.

Laravel is suitable for projects that teams are familiar with PHP and require rich features, while Python frameworks depend on project requirements. 1.Laravel provides elegant syntax and rich features, suitable for projects that require rapid development and flexibility. 2. Django is suitable for complex applications because of its "battery inclusion" concept. 3.Flask is suitable for fast prototypes and small projects, providing great flexibility.

The main difference between MySQL and MariaDB is performance, functionality and license: 1. MySQL is developed by Oracle, and MariaDB is its fork. 2. MariaDB may perform better in high load environments. 3.MariaDB provides more storage engines and functions. 4.MySQL adopts a dual license, and MariaDB is completely open source. The existing infrastructure, performance requirements, functional requirements and license costs should be taken into account when choosing.

Choosing Python or C depends on project requirements: 1) If you need rapid development, data processing and prototype design, choose Python; 2) If you need high performance, low latency and close hardware control, choose C.
