重複顧客與我想顯示結果的30天(V_Date)顯示在30天后
所以週期內重複3個或更多相同的客戶,表看起來像

當前能夠使用HAVING COUNT(name)> = 3選擇重複的3個或更多客戶,但無法在30天內檢查V_Date。 ?如何獲得預期的輸出...基於以下條件: -
Arun Kumar (V_Date 31-01-2015 to 12-02-2015)
visit (3 or more time) within 30 days
Vijay (V_Date 01-01-2015 to 15-02-2015)
Not visit (3 or more time) within 30 days
Vinoth (V_Date 01-02-2015 to 08-02-2015)
visit (3 or more time) within 30 days
Anand (V_Date 01-01-2015 to 03-03-2015)
Not visit (3 or more time) within 30 days
