DateDiff每3天一次

Question

我想知道你是否知道如何在做调度程序时每3天做一次差异.

SELECT DISTINCT 
    CLAIM_NO,
    ModifiedBy,
    ClaimType,
    ClaimStatus,
    EmailAddress,
FROM EP_ADMIN_ITEM_REMINDER
WHERE Status = 1 AND DATEDIFF(Day,DateAdded,getdate()) = 3

这是我在DATEDIFF中的代码我放入WHERE子句我有2列为date 1st DateAdded 2nd DateSent.我需要每3天安排一次我的事情,所以它会先更新datesent,它会检查datesent是否为Greterthan dateadded为3.我只想知道我的WHERE条款是否正确.谢谢

CLAIM_NO,
ModifiedBy,
ClaimType,
ClaimStatus,
EmailAddress,
FROM EP_ADMIN_ITEM_REMINDER
