如何在SQL Server中交叉表查询以列显示月份

因此，我想要的结果是保留当前列，但不是将月份全部放在一列中，而是将月份放在标题行中。如何在扩展的drop表中实现这一点。

只需在一个select查询中为每个月添加条件CASE/WHEN即可输出月份列。顺便说一下，你没有在那些月份专栏中提到你想要什么。下面我使用计数，但考虑任何其他聚集体。

这就是我得到的结果。尽管我希望包含一个case语句，该语句与where子句日期是动态的，在该范围内只输出了几个月。我可以接受这个结果。谢谢大家的意见。

您能告诉我们您想要的结果会是什么样子吗？另外，请阅读并感谢您的帮助两个问题：我还需要声明开始日期和停止日期吗？我想是的，因为我在where子句中有它。第二个问题一旦我声明了开始和停止日期，我就得到了一个语法错误，在As子句测试查询之前有一个带括号的case语句，没有那些似乎可以过滤特定记录集的日期。至于语法问题…嗯…尝试在ELSE子句中使用零而不是空。另外，我刚刚意识到，时间列先减去，然后再加上零个月，参数在DateAdd函数中被反转。只需使用dttdat字段的月份。请参见编辑。
