Sql server 他的。非常感谢你。加雷斯工作得很好。值得一提的是，这将它限制在最近一周，你知道我在过去12周内如何做到吗？@Taz它显示了最后一周，因为这是你的where谓词限制它的范围。更改where子句以适合您想要返回的内容。谢谢@SeanLange，但这不仅仅会扩大

他的。非常感谢你。加雷斯工作得很好。值得一提的是，这将它限制在最近一周，你知道我在过去12周内如何做到吗？@Taz它显示了最后一周，因为这是你的where谓词限制它的范围。更改where子句以适合您想要返回的内容。谢谢@SeanLange，但这不仅仅会扩大范围吗？我想要两行中的每一行有12个不同的日期，所以24行？当然这会扩大范围，这就是你想要的，对吗？但似乎你想按周分组，所以你需要相应地调整你的分组。有意义吗？是的，这就是我想要的，但我有点困惑我该怎么做。
