我有两个表ResourceAssign存储员工工作班。另一个表是存储项目处理日期时间。下面是创建表和示例数据的脚本。

在我的系统中，用户允许选择开始日期时间和结束日期时间以获得结果。用户可以从系统中选择开始日期2015-04-01 16:31:00和结束日期2015-04-01 19:30:00，以找出在此日期时间范围内处理的项目。使用相同的日期时间范围，用户需要知道分配谁来处理此项目。资源（员工）根据班次（每班8小时）进行分配。因此，如果用户选择开始日期2015-04-01 16:31:00和结束日期2015-04-01 19:30:00来查询项目流程，他们还需要知道谁在那个负责期间来处理选择时间范围的项目。如何获得日期时间用户选择的结果是在哪个班次？

预期的结果是

另一种情况是，如果用户选择日期范围是开始日期2015-04-01 00:00:01和结束日期2015-04-01 23:59:59，结果预期如下。即使只有1-4-2015 16:30:19 - 1-4-2015 18:40:36有项目处理，但是在用户选择的时间范围内有很少的班次或员工。它还需要作为资源分配表的结果进行查询。

1 个答案:

答案 0 :(得分：0)

您可以获取资源满足以下其中一项的Resources列表

  1. 在开始和结束范围内的整个转变
  2. 班次在范围之前开始，在范围开始之后结束

  3. 在范围开始后开始转换，在范围结束后结束

    DECLARE @Startdate DATETIME = '2015-04-01 16:31:00'
DECLARE @Enddate DATETIME = '2015-04-01 19:30:00'
--SELECT @Startdate  = '2015-04-01 00:00:01',@Enddate = '2015-04-01 23:59:59'
SELECT * FROM ResourceAssign
    WHERE (StartDate <= @Startdate AND EndDate >= @Enddate)
    OR (StartDate <=@Startdate AND Enddate >= @Startdate )
    OR (StartDate <=@Enddate AND EndDate >=@Enddate)

SELECT * FROM QuantityProcess
WHERE (StartProcessTime >=@Startdate AND EndProcessTime <= @Enddate)

    4. 您可以取消注释SELECT以获取第二个示例的输出。
