Answer 1

的MS Access你正在尋找的東西像

SELECT SYSADM_CUSTOMER_ORDER.PRINTED_DATE 
FROM SYSADM_CUSTOMER_ORDER 
WHERE (((SYSADM_CUSTOMER_ORDER.PRINTED_DATE) Between DateAdd("n",-90,Now()) And Now())); 

看一看Now Function和DateAdd Function

Answer 2

我假設你正在使用與MS Access和MS訪問後端。因爲這是VBA代碼，它不會在查詢屏幕中工作。

Dim dteBeginTime as Date 
dteBeginTime = DateAdd("n", -90, Now()) 
SELECT SYSADM_CUSTOMER_ORDER.PRINTED_DATE 
FROM SYSADM_CUSTOMER_ORDER 
WHERE PRINTED_DATE > #" & dteBeginTime & "#;"
