【交流帖】个人中心积分兑换功能报错

虽然这个功能并不是特别重要，但是这个bug如果不修补的话，说不好有点利用价值呢~~~
个人中心，点击积分，然后点开积分兑换
或者直接打开http://bbs.robomasters.com/home. ... credit&op=widthdraw
(1146) Table 'robomasters_newbbs.common_member_exchange' doesn't exist
select sum(amount) as sum from common_member_exchange where uid = '80' and status = '1'
