Question

我知道这个问题在论坛上已经被问过很多次了，我已经尝试了多种方法来获取始终需要一些错误消息的内容，因此我失去了尝试调试它的意愿。我正在用Oracle Fusion 13C编写SQL

我收到的消息是“太多值”，我很确定它来自我的最终where子句。没有最后一行的代码会带回两行正确的数据，我只想带回一行，但要基于哪一行具有“ ACTION_DATE”列中的最新日期，或者，如果失败则是“ SEQUENCE_NUM”中的最高数字柱。

到目前为止，我得到的代码是：

                    PERSON_ID AS PPNPERSONID,

感谢您提供的任何帮助。我已将其调试到最后一个SELECT的最后一个WHERE子句。如果我将其删除/注释掉最后一行，它将恢复两行。到目前为止，我带回来的数据是：

REQ_Number|FULL_NAME|SEQUENCE_NUM|REQ_TOTAL_AMOUNT|ACTION_DATE
702387     Sam Jones    3          £19,000         2017-08-23T12:08:39.000+00:00
702387     Bill Baggins  4         £19,000         2017-08-23T13:55:55.000+00:00

我只想带回Bill Baggins的那一行，因为它是两行中最近执行的那一行，但是如果无法在Action_Date上完成，那么SEQUENCE_NUM也会把它带回4> 3等

任何帮助将不胜感激。再次抱歉，这个问题无疑已经被问了很多遍了

此致

是的，这是您的问题：

AND ACTION_DATE = (SELECT MAX(PAH.ACTION_DATE), PAH.PERFORMER_ID 
                     FROM FUSION.PO_ACTION_HISTORY PAH, PER_PERSON_NAMES_F PPN 
                    WHERE PAH.PERFORMER_ID = PPN.PERSON_ID)

您的子查询返回两列MAX(PAH.ACTION_DATE)和PAH.PERFORMER_ID，但您仅通过=和ACTION_DATE来进行检查。因此，您正在将一列与两列进行比较，这是行不通的。

您可以使用(ACTION_DATE, <some other column>) = ...做类似的事情，但是我很确定这甚至不会解析，因为子查询中没有GROUP BY子句。无论如何，该子查询必须仅返回单行，否则您将获得“ ORA-01427：子查询返回多行”。

我怀疑您的子查询不是您想要的，您想删除pah.performer_id并添加一个将其与主查询相关联的子句，也许是AND PAH.PERFORMER_ID = REQ_TOTAL_AMOUNT.PPNPERSONID，也许是这样？
