我的要求是这样的：

对于在查询中传递的 PROJECTNAME，我必须从表 PSPROJECTITEM 中找出重复项。目的是找出在创建备份或迁移期间出现的重复项目。必须在两个项目之间检查行的重复性，如果它们具有相似的对象，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提取额外的重复项。

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

匹配必须在对象的基础上进行，重复是具有相同对象的对象，并且对象的数量也匹配。

记录 PSPROJECTITEM 中项目名称的副本是

意思是，这些是附加值，除此之外，附加值是这样的。

请帮助我完善此查询，以便获取查询中传递的项目的副本。

使用的数据库是oracle。

这是结果

提前感谢您的帮助，如果我错过了任何信息，请告诉我。

这是用于测试重复性的查询：

(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，它返回空白行。

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'
);

这返回：

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，我没有想法。

如果我理解正确，该项目算作重复，那么它的行数与另一个项目相同。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，因为您在项目“AZ_ASH_DASHBOARD”的名称末尾有空格：

(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'
);
