積分獲取和消費的存儲過程學習示例

 　　這篇文章主要介紹了積分獲取和消費的存儲過程學習示例，這個只是學習一下存儲過程的使用方法,需要的朋友可以參考下

　　1.GM_JF客戶賬戶積分表

　　2. GM_JF_DETAIL客戶賬戶積分消費記錄

　　3. GM_JF_ACTION _RULES積分動作規則表

　　4.GM_JF_GOODS _RULES積分商品規則表

 

-- ===============測試=======================================================

/*

declare @StatusCode int = 1;

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

print @StatusCode

*/

/*

* 判斷是否重復獲取積分(首次完善個人資料,首次修改密碼等等不能重復獲取積分)

* 判斷是根據 從GM_JF_DETAIL(詳情表)查詢周期內的數據條數與GM_JF_ACTION_RULES(動作規則表)內的周期重復次數對比

* 如果大於等於周期重復次數,則為重復獲取積分

* 接下來

*     1.詳情表的數據入庫

*     2.判斷總積分表是否存在對應客戶的總積分 沒有則插入一條新的,有 則讀取其數據,並更新
