GROUP BY + MAX（date）

-1

我嘗試遵循提供的解決方案here，但它在我的情況下不起作用。GROUP BY + MAX（date）

1）在此是我嘗試，但提出下面的錯誤的第一解決方案：

任何hel p會很感激。

Thx。

由於'max'是保留字，所以將別名'max'更改爲別的。 '）AS max USING'可能是''AS max_val USING' –

如錯誤信息所示，問題出現在'.SKU'上。刪除表名（'siz2'），使它成爲'USING（SKU，maxdate）'。 – axiac

@Abhik Chakraborty我改變了它，但我面臨着同樣的錯誤。 – seeusoon

這裏是「幾乎」工作解決方案，我至今：
不會引發錯誤，但我得到13分的結果，而不是17
我得到17分的結果，如果我刪除最後一個INNER JOIN並添加只是一個GROUP BY siz.SKU

謝謝。
