如何为商店的日程安排和店主的空闲时间创建时间段？

Question

如何使用 SQL 服务器为 Shop 的时间表创建时间段并将其映射到 Shopkeepers 时间表，并获得店主可用的时间段列表。

我有2个table；首先是商店开始时间和商店关闭时间，第二个 table 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。

如果店主正好按时工作，即从 9:00 到 17:00 轮班工作，我可以做到这一点。

问题出在店主两班倒的时候。即从上午 9 点到中午 12 点，然后是下午 2 点到 4 点。

提前致谢。

商店时间表:

id | Shop Open  | Shop Close    | ShopId    |
---+------------+---------------+-----------+
1  | 900        | 1800          |  1        |
2  | 900        | 1730          |  2        |
3  | 830        | 1600          |  3        |
4  | 845        | 1630          |  4        |

店主时间表:

ShopkeeperId | Shopkeeper Start     | Shopkeeper End    | ShopId    |
-------------+----------------------+-------------------+-----------+
1            | 900                  | 1800              |  1        |
2            | 900                  | 1200              |  1        |
2            | 1400                 | 1700              |  1        |
3            | 830                  | 1600              |  2        |
4            | 845                  | 1630              |  2        | 
4            | 845                  | 1630              |  2        |

日程安排:

ShopkeeperId    | ShopId  | ShopSlot Start  | ShopSlot Start    | Shopkeeper Avialable  |

这是一种使用各种临时表生成计划的方法：

-- ================================================
-- GIVEN DATA - Table of ShopKeeper Schedule 
CREATE TABLE #SKSchedule (
    ShopKeeperId int
    , ShopKeeperStart int
    , ShopKeeperEnd int
    , ShopID int
    );

INSERT INTO #SKSchedule VALUES
(1            , 900                  , 1800              ,  1        )
,(2            , 900                  , 1200              ,  1        )
