积分获取和消费的存储过程学习示例
2014-05-12来源:

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

代码如下:

-- ===============测试=======================================================

/*

declare @StatusCode int = 1;

exec sp_GM_JF_AddScore 'admin','AN_JF_001_001',1,5,0,'',@StatusCode output

print @StatusCode

*/

-- ===========================================================================

/*

* 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

*
