首先需要

import pymysql

1.連線資料庫

#獲取資料庫連線
def getDBConn():
	conn = pymysql.connect(
		host = 'localhost',
		port = 3306,
		user = 'root',
		password = '123',
		db = 'insurancedata',
		charset = 'utf8'
    )
	return conn

2.關閉資料庫連線

def closeConn(cursor,conn):
	if cursor:
		cursor.close()
	if conn:
		conn.close()
 

3.插入資料

#插入資料
def inset_To_url_table():
	try:
		conn = getDBConn()
		cursor = conn.cursor()
		sql = "INSERT INTO url_table(url,url_state)VALUES(%s,%s)"
		url = "http://baidu.com/item/123"
		status = "0"
		params = (url,status)
		cursor.execute(sql,params)
		conn.commit()
	except:
		conn.rollback()
		print('insert error')
	finally:
		closeConn(cursor,conn)
 

4.查詢資料

def select_url_table(URL):
	try:
		conn = getDBConn()
		cursor = conn.cursor()
		sql = "SELECT url_state from url_table WHERE url = URL"
		cursor.execute(sql)
		url_state = cursor.fetchall()[0][0]
		return url_state
	except:
		print('select error')
		return None
	finally:
		closeConn(cursor,conn)
