检索多个但不是所有字段但同一列
Retrieving multiple but not all fields but same column
我需要从存储行程 ID 号的 excel 文档中为 driver 填充 Rota table。
在上传到应用程序时，我需要它通过 SP
从 运行s table 获取每天 运行 的开始时间
这部分不是问题，一切正常当某些日子为“0”（休息日）时问题就开始了，所以除非 driver 是一周中的每一天，否则数据不会return.
我知道这不是很吸引人 SQL 但它只是一个快速 mock-up 来解释问题。
这里是T-SQL

好吧，联合枢轴的想法我无法工作，但我确实找到了另一种方法，它可以帮助那些枢轴对他们也不起作用的其他人。
只需声明每天的变量和 运行 每个变量的单一查询，将它们转储到临时 table 和 select * table.
它会比组合查询更有效吗，可能不会。
这是最干净/最简洁的方法吗，绝对不是。
它能完成工作吗？
如果有人希望post更好的版本，显然请这样做。
