                ORDER BY MAX (ID) ASC, STAUS_YEAR_MONTH DESC)
ORDER BY EQUIPMENT_ID

Answer 1

ORDER BYinIN子句查询不是必需的，而且它没有任何作用并引发错误。

您的查询应如下所示：

SELECT EQUIPMENT_ID
    FROM IRRI_EQUIPMENT_STATUS_CHANGE
   WHERE ID IN(SELECT MAX (ID)
                    FROM IRRI_EQUIPMENT_STATUS_CHANGE
                   WHERE STAUS_YEAR_MONTH <= 105
                GROUP BY EQUIPMENT_ID, STAUS_YEAR_MONTH)
ORDER BY EQUIPMENT_ID

干杯！！
