pysql用类进行封装

pyMySQL用类进行封装

class SqlHelper(object):

	def __init__(self):
		self.connect()

	def connect(self):
		self.conn = pymysql.connect(host="localhost", user="root", password="密码", db="studentmanage",
                                    charset='utf8')
        self.cursor = self.conn.cursor(cursor=pymysql.cursors.DictCursors)

    def get_list(self,sql,args):
    	self.cursor.execute(sql,args)
    	result = self.cursor.fetchall()
    	return result
    def get_one(self,args):
    	self.cursor.execute(sql,args)  
    	result = self.cursor.fetchone()
    	return result
    def modify(self,sql):
    	self.cursor.execute(sql,args)
    	self.conn.commit()
    def create(self,sql):
    	self.cursor.execute(sql,sql)
    	self.conn.commit()
    	return self.cursor.lastrowid
    def close(self):
    	self.cursor.close()
    	self.conn.close()
