Question

嗨，我的 DOMP_LOG_EVENT table

上有这些数据

DOCID                        DOC_VERSION    CN_NO   SEQ USERID  EVENT_DESC  DATE_LOG    REMARKS UPLOAD_DATE

我想得到这样的查询结果

Document Submitted for Deployment 应该在 Document Deployed

之前先走

这是我当前的查询

Select doc_version, date_log, event_desc, userid, nvl(fullname,userid) as fullname from domp_log_event A, dom_appusers b
 where a.userid = b.username(+) and round(doc_version) = '0' and docid ='7a32bf6024264a109ce32d05c52d70f8' order by docid, date_log,userid DESC, seq  ,doc_version

如何在不更改 table

上的数据的情况下实现它

Answer 1

我再次查看了示例数据，我认为以下 ORDER BY 会起作用：

 ORDER BY DOCID,
          DOC_VERSION DESC,
          DATE_LOG,
          DECODE(EVENT_DESC,'Document Submitted for Deployment',1,
                            'Document Deployed',2,
                 3) -- added this
