你想要什么样的发货日期？这是一个很好的起点。看起来你想要一个动态轴心。。。三次。。。这是不可能的sense@SeanLange我的坏毛病是我修好的。感谢您的奇怪输出，但您可以通过动态交叉表轻松解决此问题。由于您试图将[ship date]和[customer]保留为一列，因此我认为如果没有某种循环（光标、while等），您无法实现这一点，或者是否仍可以包括[customer1][customer2]和[ship date1][ship date2]，然后使用view或cte过滤掉它们？非常感谢Chris！！如何将该值插入另一个表记录在##Results_2017_06_28表中。您可以使用“insert into”，但由于我们不知道执行时的列是什么，因此必须使用“*”。我试图找出一种方法，至少能让它们按正确的顺序排列，但现在证明这是不可能的。这会被应用程序使用吗？谢谢Chris，工作很好。当

ship date

=getdate（）时，我可以在此基础上创建触发器吗？`为什么要创建触发器？我是DBA新手，但有一件事我听说过，也看到过，触发器可能非常糟糕（隐藏复杂性，因为它会造成复杂性），而且在大多数情况下，创建更好的解决方案可以轻松避免。每天或每小时触发插入
