查詢顯示錯誤結果

Question

我下面查詢獲取記錄從表penilaian_header & penilaian_detail

select *  
from 
( 
    select 
     row, a.tanggal,b.OutletCode,c.Nilai,a.Nip,b.Fullname,a.KodePenilaian, 
     f.Description as posisilama, d.ShortDesc as posisibaru 
    from penilaian_header a 
     left join Employee b on a.Nip = b.Nip 
     left join Position f on b.PositionCode = f.PositionCode 
     left join Position d on a.PositionCode = d.PositionCode 
     left join Penilaian_Detail e on a.KodePenilaian = e.KodePenilaianH 
     left join arealeader g on g.OutletCode = b.OutletCode 
     left join (
        select 
         ROW_NUMBER() OVER(PARTITION BY KodePenilaianH ORDER BY idPenilaiand DESC) AS Row, 
         Nilai, 
         KodePenilaianH 
        from penilaian_Detail 
        ) c on a.KodePenilaian = e.KodePenilaianH 
    where a.Outlet like '%%' and Periode like '%%' 
) nilai 
pivot 
( 
    sum(nilai) for row in ([1],[2],[3],[4],[5]) 
) piv; 

我在penilaian_header

記錄我的紀錄penilaian_detail

WHE ñ我運行我的查詢，我得到了這個結果。

結果應該與penilaian_detail相同。請告訴我如何解決它。

感謝@dhruvjoshi的說明。現在的結果是像什麼，我預計

首先，我刪除此 left join Penilaian_Detail e on a.KodePenilaian = e.KodePenilaianH

然後我在結果改變這種 on a.KodePenilaian = e.KodePenilaianH到on a.KodePenilaian = c.KodePenilaianH

的問題是，由於JOINs你有重複的行設置爲內部查詢。 See inner query fiddle evaluation

更正查詢低於

select *  
from 
(
    select 
     distinct ---added distinct here to avoid repetition 
     row, a.tanggal,b.OutletCode,c.Nilai,a.Nip,b.Fullname,a.KodePenilaian,f.Description as posisilama,d.ShortDesc as posisibaru 
    from penilaian_header a 
     left join Employee b on a.Nip = b.Nip 
     left join Position f on b.PositionCode = f.PositionCode 
     left join Position d on a.PositionCode = d.PositionCode 
     left join Penilaian_Detail e on a.KodePenilaian = e.KodePenilaianH 
     left join arealeader g on g.OutletCode = b.OutletCode 
     left join (
        select 
         ROW_NUMBER() OVER(PARTITION BY KodePenilaianH ORDER BY idPenilaiand DESC) AS Row, 
         Nilai,KodePenilaianH 
        from penilaian_Detail 
        ) c on a.KodePenilaian = e.KodePenilaianH 
) nilai 
pivot 
(
    sum(nilai) 
    for row in ([1],[2],[3],[4],[5]) 
) piv;
