Python連接mysql和操作

軟件：pycharm

開始在pycharm下面的Terminal中安裝mysql時提醒pip版本不夠，所以需要先升級一下pip

python -m pip install --upgrade pip

升級完pip之后就可以下載mysql

pip install mysql

下載完成后在setting中查看

進行代碼測試

#!/usr/bin/python

#-*- coding: UTF-8 -*-

importMySQLdb

db=MySQLdb.connect("localhost","root","liu123","test",charset=‘utf8‘)

cursor=db.cursor()

cursor.execute("SELECT VERSION()")

data=cursor.fetchone()

print ("Database version : %s" %data)

db.colse()

Database version : 5.7.10-log

插入

#!/usr/bin/python

#-*- coding: UTF-8 -*-

importMySQLdb

db=MySQLdb.connect("localhost","root","liu123","test",charset=‘utf8‘)

cursor=db.cursor()

sql="insert into admin(account,passwd) values (‘abc‘,‘123456789‘)"

try:

cursor.execute(sql)

db.commit()

except:

db.rollback()

db.close()

查找

#!/usr/bin/python

#-*- coding: UTF-8 -*-

importMySQLdb

db=MySQLdb.connect("localhost","root","liu123","test",charset=‘utf8‘)

cursor=db.cursor()

sql="select * from admin"

try:

cursor.execute(sql)

results=cursor.fetchall()forrow in results:

account=row[0]

password=row[1]

print("account=%s,password=%s" %(account,password))

except:

print("Error:unable to fetch data")

db.close()

更新

try:

cursor.execute(sql)

db.commit()
