Question

我有以下SQL。问题是它只在以下输出中显示结果：wp.gtid，wp.first_name等我也想显示来自wpe.gtid，wpe.first_name等的结果。这样我就可以轻松地并排比较各个字段。

with dups as (
    select 
          wp.GtId
        from CORE.WeccoParty wp
    where exists (select 1
                  from CORE.WeccoParty wpe
                -- where wp.Tin = wpe.Tin
                where wp.FirstName = wpe.LastName
                  and   wp.GtId     <> wpe.GtId    
              )
      )
       select distinct
      wp.GtId, 
      wp.CrmPartyId, 
      wp.LegalName, 
      wp.BusinessClass, 
      wp.RmFullName, 
      wp.PbeFullName, 
      wp.OverallClientStatus, 
     wp.OverallRpStatus, 
       wp.FirstName,
      wp.LastName,
      wp.Tin


from CORE.WeccoParty wp
join dups d on d.GtId = wp.GtId
order by 1,2

K1205，当我检查您的代码时，似乎发现duplicate entries具有相同的名字但GtId值不同

所以也许您可以对Row by Number子句使用Row_Number（）函数

能否请您检查以下SQL？

select 
    ROW_NUMBER() over (Partition By wp.FirstName Order By wp.GtId) as rn,
    wp.GtId, 
    wp.CrmPartyId, 
    wp.LegalName, 
    wp.BusinessClass, 
    wp.RmFullName, 
    wp.PbeFullName, 
    wp.OverallClientStatus, 
    wp.OverallRpStatus, 
    wp.FirstName,
    wp.LastName,
    wp.Tin
from CORE.WeccoParty wp
order by wp.FirstName, rn

我希望以下CTE查询可以为您提供解决方案重复的数据（名字和gtid）的数据在相同名字的第一个条目之后添加为新列

with rawdata as (
    select 
        ROW_NUMBER() over (Partition By wp.FirstName Order By wp.GtId) as rn,
        wp.GtId, 
        wp.CrmPartyId, 
        wp.LegalName, 
        wp.BusinessClass, 
        wp.RmFullName, 
        wp.PbeFullName, 
        wp.OverallClientStatus, 
        wp.OverallRpStatus, 
        wp.FirstName,
        wp.LastName,
        wp.Tin
    from WeccoParty wp
)
select t1.*, t2.GtId, t2.FirstName 
from rawdata as t1
inner join rawdata as t2
    on t1.FirstName = t2.FirstName and
       t1.rn <> t2.rn
where t1.rn = 1
order by t1.FirstName, t2.rn

在选择中显示临时表中的字段
