Question

我尝试按照here提供的解决方案，但在我的情况下不起作用。

1）这是我尝试的第一个解决方案，但引发了以下错误：

SQL错误（1064）：您的SQL语法中有错误;检查手册，对应右边的MySQL服务器版本在'.SKU，maxdate'附近使用的语法WHERE inv.outbound_date IS NOT NULL AND co.system ='Magent'在第26行

任何帮助都会受到赞赏。

Answer 1

这是我到目前为止的“几乎”工作解决方案：
没有错误，但我得到13个结果，而不是17 如果我删除最后一个INNER JOIN并仅添加GROUP BY siz.SKU

，我会得到17个结果
