Python中返回SQL字段名

    def ReturnInfo(self, avalue, akey):
        cursor = connection.cursor()
        if type(avalue) == int:
            Sql = "select * from %s where %s=%s" % (self.table, akey, avalue)
        else:
            Sql = "select * from %s where %s = '%s'" % (self.table, akey, avalue)
        cursor.execute(Sql)
        SqlDomain = cursor.description            ####
        DomainNum = len(SqlDomain)
        SqlDomainName = [None]*DomainNum
        for i in range(DomainNum):
            SqlDomainName[i] = SqlDomain[i][0]
        SqlResult = cursor.fetchall()             ####
        cursor.close()
        result = [None]*2
        result[0] = SqlDomainName
        result[1] = SqlResult
        return result

cursor.description 方法，列出table中每个字段的属性。返回一个二元元祖，（(.., .., .., ..), (), (), )
cursor.fetchall 方法， 按字段顺序，列出每一行的值。返回一个二元元组,（(.., .., .., ..), (), (), )
