Question

我的要求是：

我必须从表PSPROJECTITEM中找到在查询中传递的PROJECTNAME的重复项。目标是找出在创建备份或迁移期间出现的重复项目。行的重复必须在两个项目之间进行检查，如果它们有类似的对象，如objecttype，objectid1等，并且这些对象的计数匹配，则它们是重复的。

我的问题是我写的查询会获得额外的副本。

SELECT a.PROJECTNAME 
 , a.OBJECTTYPE 
 , a.OBJECTID1 
 , a.OBJECTVALUE1 
 , a.OBJECTID2 
 , a.OBJECTVALUE2 
 , a.OBJECTID3 
 , a.OBJECTVALUE3 
 , a.OBJECTID4 
 , a.OBJECTVALUE4,
 COUNT(*) as duplicate
  FROM PSPROJECTITEM a 
 WHERE a.projectname <> 'AZ_11' and
       exists ( 
 SELECT *
  FROM PSPROJECTITEM c 
 WHERE c.projectname  = 'AZ_11' 
   and a.objecttype = c.objecttype 
   AND a.objectid1 =c.objectid1 
   AND a.objectvalue1 = c.objectvalue1 
   AND a.objectid2 = c.objectid2 
   AND a.objectvalue2 = c.objectvalue2 
   AND a.objectid3 = c.objectid3 
   AND a.objectvalue3 = c.objectvalue3 
   AND a.objectid4 = c.objectid4 
   AND a.objectvalue4 = c.objectvalue4) 
   group by a.PROJECTNAME 
 , a.OBJECTTYPE 
 , a.OBJECTID1 
 , a.OBJECTVALUE1 
 , a.OBJECTID2 
 , a.OBJECTVALUE2 
 , a.OBJECTID3 
 , a.OBJECTVALUE3 
 , a.OBJECTID4 
 , a.OBJECTVALUE4
  ORDER BY a.projectname

必须在对象的基础上进行匹配，并且复制是具有相同对象的对象，并且对象的计数也匹配。

记录PSPROJECTITEM中projectname的副本是

A_RP    7   10  AZ_EP_DASHBOARD 39  GBL 0       0    
A_RP    46  10  AZ_EP_DASHBOARD 39  GBL 12  PostBuild   0

查询还会获取这些值：

意思是，这些是附加值，除此之外，额外的值是这样的。

请帮助我完成此查询，以便获取正在查询中传递的项目的副本。

正在使用的数据库是oracle。

这是

的结果

如果我提前得到了帮助，请告诉我是否遗漏了任何信息。

这是用于测试重复项的查询：

(SELECT COUNT(*) FROM PSPROJECTITEM
WHERE PROJECTNAME='AZ_11'
minus
SELECT COUNT(*) FROM PSPROJECTITEM
WHERE PROJECTNAME='A_RP') 
union all
( 
 SELECT COUNT(*) FROM PSPROJECTITEM
WHERE PROJECTNAME='A_RP'
minus
SELECT COUNT(*) FROM PSPROJECTITEM
WHERE PROJECTNAME='AZ_11'
);

为此，它返回空行。

当我使用这些值运行时：

(SELECT COUNT(*) FROM PSPROJECTITEM
WHERE PROJECTNAME='AZ_11'
minus
SELECT COUNT(*) FROM PSPROJECTITEM
WHERE PROJECTNAME='AZ_ASH_DASHBOARD ') 
union all
( 
 SELECT COUNT(*) FROM PSPROJECTITEM
WHERE PROJECTNAME='AZ_ASH_DASHBOARD '
minus
SELECT COUNT(*) FROM PSPROJECTITEM
WHERE PROJECTNAME='AZ_11'
);

这种影响：

65
0

这意味着，这些不是重复的项目，因为对象不匹配。

只是帮助我解决这个问题，这非常复杂，而且我的想法不合理。

Answer 1

如果我理解正确，项目计为重复，那么它与另一个项目具有相同的行数。尝试在子查询中添加此条件，例如：

SELECT a.PROJECTNAME 
 , a.OBJECTTYPE 
 , a.OBJECTID1 
 , a.OBJECTVALUE1 
 , a.OBJECTID2 
 , a.OBJECTVALUE2 
 , a.OBJECTID3 
 , a.OBJECTVALUE3 
 , a.OBJECTID4 
 , a.OBJECTVALUE4,
 COUNT(*) as duplicate
  FROM PSPROJECTITEM a 
 WHERE a.projectname <> 'AZ_11' and
       exists ( 
 SELECT *
  FROM PSPROJECTITEM c 
 WHERE c.projectname  = 'AZ_11' 
   and a.objecttype = c.objecttype 
   AND a.objectid1 =c.objectid1 
   AND a.objectvalue1 = c.objectvalue1 
   AND a.objectid2 = c.objectid2 
   AND a.objectvalue2 = c.objectvalue2 
   AND a.objectid3 = c.objectid3 
   AND a.objectvalue3 = c.objectvalue3 
   AND a.objectid4 = c.objectid4 
   AND a.objectvalue4 = c.objectvalue4) 
   AND (SELECT COUNT(*) FROM PSPROJECTITEM d
   WHERE d.projectname = a.projectname) = 
   (SELECT COUNT(*) FROM PSPROJECTITEM e
   WHERE e.projectname = 'AZ_11')
   group by a.PROJECTNAME 
 , a.OBJECTTYPE 
 , a.OBJECTID1 
 , a.OBJECTVALUE1 
 , a.OBJECTID2 
 , a.OBJECTVALUE2 
 , a.OBJECTID3 
 , a.OBJECTVALUE3 
 , a.OBJECTID4 
 , a.OBJECTVALUE4
  ORDER BY a.projectname

另外，我认为，此查询会返回此结果，因为项目名称末尾有空格“AZ_ASH_DASHBOARD”：

(SELECT COUNT(*) FROM PSPROJECTITEM
WHERE PROJECTNAME='AZ_11'
minus
SELECT COUNT(*) FROM PSPROJECTITEM
WHERE PROJECTNAME='AZ_ASH_DASHBOARD ') 
union all
( 
 SELECT COUNT(*) FROM PSPROJECTITEM
WHERE PROJECTNAME='AZ_ASH_DASHBOARD '
minus
SELECT COUNT(*) FROM PSPROJECTITEM
WHERE PROJECTNAME='AZ_11'
);

获得额外的重复值
