Sql server 我如何为店铺的时间表和店主的可用性创建时间段？

如何为店铺的时间表创建时间段，并将其映射到店主时间表，并使用SQL Server创建店主可用的时间段列表

我有两张桌子；第一张是开店时间和关门时间，第二张是店主时间表

我想创建15分钟的时间段，并标记店主是否有空

如果店主刚好按计划工作，即从9:00到17:00一班工作，我可以做到这一点

问题是当店主两班倒工作时。i、 e.从上午9点到下午12点，然后是下午2点到4点

提前谢谢

车间时间表：

店主时间表：

非常感谢你。节省了我很多时间。如果一个插槽可以有多个预订，您建议如何更改此设置。假设我的店主是一名医生，在30分钟的时间里最多可以看3个病人？那么我们如何调整它来找到一个位置呢？谢谢，非常感谢。节省了我很多时间。如果一个插槽可以有多个预订，您建议如何更改此设置。假设我的店主是一名医生，在30分钟的时间里最多可以看3个病人？那么我们如何调整它来找到一个位置呢？谢谢
