积分获取和消费的存储过程学习示例

1.gm_jf客户账户积分表

2. gm_jf_detail客户账户积分消费记录

3. gm_jf_action _rules积分动作规则表

4.gm_jf_goods _rules积分商品规则表

/*
* 判断是否重复获取积分(首次完善个人资料,首次修改密码等等不能重复获取积分)
* 判断是根据 从gm_jf_detail(详情表)查询周期内的数据条数与gm_jf_action_rules(动作规则表)内的周期重复次数对比
* 如果大于等于周期重复次数,则为重复获取积分
* 接下来
*     1.详情表的数据入库
*     2.判断总积分表是否存在对应客户的总积分 没有则插入一条新的,有 则读取其数据,并更新
