我正在做报告换班报告我有3个班次：
shift1 starts at 7am and ends at 3pm
shift2 starts at 3pm and ends at 11pm
shift3 starts at 11pm and ends at 7am
我必须根据班次生成报告。例如，如果用户从下拉列表中选择shift1，则报告应显示从早上7点到下午3点的所有数据。
我能够获取shift1和shift2的数据，但我无法获取shift3数据，因为 在shift3之后的12点，日期将会改变。
那么如何获取shift3的数据并根据这4个表中的日期获取数据
我的第一张表包含以下数据（shift3（11-7））：

压力和pH相同，只有压力柱和ph柱值会改变。
我在数据库中存储数据，有4个表，日期是我的主要关键。 我必须根据日期链接这些数据。
我在gridview中显示数据。
我希望我的输出像这样：

有人可以帮我吗？
答案 0 :(得分：0)
你需要找出要求 - 当有人选择第3班和日期时，他们可能意味着3件不同的事情：
报告从该日开始的班次3。
关于在该日期结束的班次3的报告。
报告该日从午夜到早上7点和11点到午夜3点班次。
如果人们真的按日期收到报告，那么我希望他们会想要最后一份报告。
