 Suresh      100     cccc            Yes

重复的名字不会第二次出现在这里＆＃39; UserName＆＃39;和＆＃39;费用＆＃39;列是重复的列..

Answer 1

请尝试：

select 
    case when RNum=1 then UserName else '' end UserName,
    case when RNum=1 then Fee else '' end Fee,
    ReferenceName,
    Billed 
from(
    select 
        *, 
        ROW_NUMBER() over (partition by UserName order by UserName) RNum 
    from tbl
)x

Answer 2

可能你可以试试这个

select 
    case when RANKK=1 then USERNAME else '' end USERNAME,
    case when RANKK=1 then FEE else '' end FEE,
    REFERENCENAME,
    BILLED 
from(
    select 
        A.*, 
        RANK over (partition by USERNAME,FEE order by USERNAME) AS RANKK 
    from MY_TABLE A
)x

在Sql中隐藏重复的行值
