我尝试遵循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，但出现以下错误：

ORDER BY siz.SKU;
任何帮助将不胜感激。
谢谢。
【问题讨论】：
-
将别名
max更改为其他名称，因为max是保留字。) AS max USING可能是) AS max_val USING -
如错误消息所述，问题出在
.SKU。去掉表名（siz2），改成USING (SKU, maxdate)。 -
@Abhik Chakraborty 我改变了它，但我面临同样的错误。
-
@axiac 我删除了别名，现在出现了一个新错误：SQL 错误 (1054): Unknown column 'maxdate' in 'from clause'
-
请注意，
siz2.SKU是派生查询的一部分，因此您需要使用用于派生查询的别名GROUP siz2.SKU ) AS max_val USING (max_val.SKU, max_val.maxdate)
