你好。当我从数据库中选择时，它返回我这样的结果。第7列是“STATECHANGETIME”我想编写只返回最后一次更改的sql（第7列的最大值）

我的sql是：

SELECT ORG.DESCRIPTION, ORG.EXTERNALKEY, P.VALUE AS VOEN, AGR.STATECODE, AGR.STATECHANGEDATE, AGR.STATECHANGETIME
FROM organization org, AGREEMENT AGR, PROPERTY P, PMTSVCAGREEMENT PSA
WHERE     AGR.RECEIVERID = ORG.ID AND P.ID = ORG.ID AND PSA.ID=AGR.ID
    AND P.IDX = 4 AND (org.ownerid = (SELECT id 
                                      FROM organization
                                      WHERE externalkey = '960000') 
    OR ORG.EXTERNALKEY = '960000')
ORDER BY CASE WHEN ORG.EXTERNALKEY = '960000' THEN 0 ELSE 1 END, ORG.DESCRIPTION;

如何写它。谢谢你

我想要检索此结果：

如果没有更多信息，我猜this code可以帮助您。它按降序排列STATECHANGEDATE, STATECHANGETIME排序，然后使用

获取第一组返回值

WHERE ROWNUM <= 1

希望它有所帮助。
