Question

我的select查询中有一个时间/日期字段，我想将条件设置为仅输出最近90分钟的记录。请给我正确的SQL来复制/粘贴非常感谢Nathaniel

SELECT SYSADM_CUSTOMER_ORDER.PRINTED_DATE
FROM SYSADM_CUSTOMER_ORDER;

Answer 1

对于MS Access，您正在寻找类似

的内容

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

查看Now Function和DateAdd Function

Answer 2

我假设您正在使用MS Access和MS Access后端。因为这是VBA代码，所以它在查询屏幕中不起作用。

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

查询标准，输出最近90分钟的记录
