　　涉及到的数据库代码

class JobPositionDao(BaseDao):

    def __init__(self):
        super().__init__()
    #   查询python所有岗位的描述
    def findPythonDetail(self):
        sql = "SELECT jd.detail_desciption FROM `job_position_detail` as jd,`job_position` as jp,`job_collect_task` as jc WHERE jd.detail_positionid=jp.job_id and jp.job_taskid=5;"
        result = self.execute(sql, params=None)
        self.commit()
        return self.fetch()
        pass
