我在表格中有两列代表start和end的员工工作时间（It Stores HH：MM：SS）。我有另一个表作为堆栈，我存储繁忙的时间。假设我将此存储为start为8:00:00且end为17:00:00
startColumn endColumn
08:15:00.0000000 08:45:00.0000000
11:00:00.0000000 12:00:00.0000000
12:00:00.0000000 13:00:00.0000000
考虑到上面的数据在表中，我希望得到以下结果：
8:00 A.M
8:45 A.M
10:00 A.M
1:00 P.M
2:00 P.M
3:00 P.M
4:00 P.M
提前致谢！

如果我理解你的话，你只处理整个小时：
这将挑选员工的工作时间：
简短说明：在声明的表变量中填写测试数据后，我从CTE开始创建一个从06:00到20:00的所有小时的列表。最终SELECT检查表中是否存在条目＆＃34;工作＆＃34;当前小时是否在intervall内。如果包含EndHour，您可以自行决定。从这个角度来看，您自己的样本数据不一致。
如果您真的只想要非工作时间，可以将CASE WHEN - 逻辑转换为WHERE ...
请注意，您需要进一步的逻辑来区分不同的员工，工作日以及每个工作日的不同时间标准（星期五以外的星期五......）
