Question

我有一个查询

SELECT clientcode, 
       branchcode, 
       maincode, 
       name, 
       actype, 
       cycode 
FROM   Master 
WHERE  name IN (SELECT name 
                FROM   Master 
                GROUP  BY name 
                HAVING Count(name) > 1) 
       AND isblocked <> 'C' 
       AND actype < '4E' 
ORDER  BY branchcode, 
          name, 
          actype, 
          cycode

现在我需要从上面查询的输出中选择名称相同但ClientCode不同的行。

对于例如，两行具有相同的名称，假设'BISHNU BHANDARI'但是它们应该具有不同的clinetCode，例如'123'用于一个，'444'用于另一个。

您可以在having部分添加一个附加条款：

SELECT clientcode, 
       branchcode, 
       maincode, 
       name, 
       actype, 
       cycode 
FROM   Master 
WHERE  name IN (SELECT name 
                FROM   Master 
                GROUP  BY name 
                HAVING Count(name) > 1
                and min (clientcode) != max (clientcode)) 
       AND isblocked <> 'C' 
       AND actype < '4E' 
ORDER  BY branchcode, 
          name, 
          actype, 
          cycode

如果客户端代码可以为空并且您希望null满足不等式条件，则这可能不起作用，但这很容易添加。

尝试

SELECT min(clientcode), max(clientcode), count(distinct clientcode), 
       branchcode, 
       maincode, 
       name, 
       actype, 
       cycode 
FROM   master 
WHERE  name IN (SELECT name 
                FROM   master 
                GROUP  BY name 
                HAVING Count(name) > 1) 
       AND isblocked <> 'C' 
       AND actype < '4E' 
group by        branchcode, 
       maincode, 
       name, 
       actype, 
       cycode 
having 1 < count(distinct clientcode)
order by        branchcode, 
       maincode, 
       name, 
       actype, 
       cycode

如果名称属于不同的分支代码等你必须从“分组依据”中删除这些字段并选择它们像我上面的客户端代码一样进行聚合

SELECT行在一个Field中具有相同值但在另一个相应字段中具有不同值
