GROUP BY + MAX（date）

-1

我尝试遵循提供的解决方案here，但它在我的情况下不起作用。GROUP BY + MAX（date）

1）在此是我尝试，但提出下面的错误的第一解决方案：

2）在此是第二溶液我尝试，但没有按结果的数量” t匹配结果的数量如果我做一个简单的GROUP BY

任何hel p会很感激。

由于'max'是保留字，所以将别名'max'更改为别的。 '）AS max USING'可能是''AS max_val USING' –

如错误信息所示，问题出现在'.SKU'上。删除表名（'siz2'），使它成为'USING（SKU，maxdate）'。 – axiac

@Abhik Chakraborty我改变了它，但我面临着同样的错误。 – seeusoon

这里是“几乎”工作解决方案，我至今：
不会引发错误，但我得到13分的结果，而不是17
我得到17分的结果，如果我删除最后一个INNER JOIN并添加只是一个GROUP BY siz.SKU

谢谢。
