Sql 如何返回过去90天内没有活动日期的记录？

我有一个查询，可以返回过去90天内没有活动的所有记录，但它似乎也在返回过去90天内活动的记录。我怎样才能解决这个问题

检查它们是否处于活动状态的逻辑-

tm.timeslip\u date
。。。。。。。。。。。。。。。
左连接dbo.timeslips tm
关于cases.case_sk=tm.case_sk
--和tm.timeslip_date DATEADD（day，-90，GETDATE（））
.........................
和tm.timeslip\u日期请在代码问题中给出一个--cut&paste&runnable代码，包括作为代码输入的最小代表性示例；期望和实际输出（包括逐字记录错误消息）；标签和版本；清晰的说明和解释。尽可能少地给出代码，即显示为OK的代码，并通过显示为not OK的代码进行扩展。（调试基础。）用于包含DBMS和DDL（包括约束和索引）的SQL，并将其作为格式化为表的代码输入。暂停总体目标的工作，在第一个表达中删去代码，不要给出你的期望，说出你的期望以及为什么。请。仅将图像用于不能表示为文本或扩充文本的内容。包括图例/图例和说明以及图像。@谢谢您的帮助info@philipxy谢谢你提供的信息。下次我会关注这些。非常感谢。我请求你的帮助。它起作用了。
