嘿，你为什么不喜欢我的问题？你可以添加一个“月”表，然后在表上留下join（顺便说一下，不是downvoter）。无法理解要求。是否需要进行年度比较？您能看到我的查询吗？我已经加入了该专栏，但如果没有该月份的数据，则不会打印四月-月号。维卡斯先生，我有显示税收和价格的表格。如果我在四月份没有销售任何产品，那么我如何才能获得零销售和零税的四月份coulmn。所以我也可以显示那个月的数据。嘿，我不知道怎么把我的问题放到SQL Fiddle上。这是一个测试平台。就像我创建了一个模式并添加了一些查询一样，那样的话“”意味着我必须创建所有表，并且必须在其中插入值来放入一些测试值，并且只放入那些是此查询基本要求的列。因此可以理解依赖关系。我的cte表达式工作正常，但只有您已更正的条件不工作。。。我的解决方案对你有用吗？我试图解释我的想法，但你似乎不明白。如我向你建议的那样，尝试在年月日加入，如果不起作用，请尝试向我解释你的问题。如果你愿意，我们可以打开聊天室吗？我们可以发送聊天室的链接吗？我花了2个小时搜索如何创建聊天室，我失败了。如果您需要更多帮助，只需解释（上下文、问题、示例）。非常感谢您宝贵的时间，我也不知道如何开始聊天，但我们确实可以在堆栈溢出上彼此聊天，但我不知道如何开始聊天，先生。
