python mysql 查询返回字典结构

cur = self.conn.cursor(MySQLdb.cursors.DictCursor)加上MySQLdb.cursors.DictCursor可以返回字典结构

{列名:值}

class MYSQL():
def __init__(self,host,user,pwd,db):
self.host = host
self.user = user
self.pwd = pwd
self.db = db
def __GetConnect(self):
"""
得到连接信息
返回: conn.cursor()
"""
if not self.db:
raise(NameError,"没有设置数据库信息")
self.conn = MySQLdb.connect(self.host,self.user,self.pwd,self.db,charset='utf8')
cur = self.conn.cursor(MySQLdb.cursors.DictCursor)#返回字典结构
if not cur:
raise(NameError,"连接数据库失败")
else:
return cur
def ExecQuery(self,sql):

cur = self.__GetConnect()
cur.execute(sql)
resList = cur.fetchall()

#查询完毕后必须关闭连接
self.conn.close()
return resList
