pymysql 操作數據庫 (含使用socket連接數據庫的方法)

db = pymysql.connect(host="127.0.0.1", user="root",password="root", db="mysql", port=3306, charset='utf8',unix_socket="/Applications/MAMP/tmp/mysql/mysql.sock")

connect里面的參數參考: https://www.jianshu.com/p/4850afe7098f

unix_socket為使用socket登錄，我用mamp中的phpmyadmin 有給的

 

正常鏈接

db = pymysql.connect("數據庫地址","賬號","密碼","庫名")

例子:

一:

#連接測試數據庫數據庫
db = pymysql.connect("數據庫地址","賬號","密碼","訪問的數據庫")      ##這里這樣默認填可能會說傳入參數過多的解決方法 https://www.cnblogs.com/kaibindirver/p/14425482.html

二: 使用socket連接

db = pymysql.connect(host="127.0.0.1", user="root",password="root", db="訪問的數據庫", port=3306, charset='utf8',unix_socket="/Applications/MAMP/tmp/mysql/mysql.sock")
