嗨，大家好。当我从数据库中选择时，它会返回这样的结果。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;

怎么写。感谢你

我希望检索此结果：

如果没有更多信息，我想这段代码可以帮助你。它获取按STATECHANGEDATE, STATECHANGETIME降序排序的集合，然后通过使用

WHERE ROWNUM <= 1

希望能帮助到你。
