SQLクエリから重複レコードを取得する

Question

SQL Serverでそのクエリを実行中に誰かが私を助けてもらえますか重複レコードがあります。私は& BILL_DETAILIDの両方のシナリオで内部結合を残してみましたが、私は重複レコード&も使用していますが、 "別個"を使用しても同じ問題に直面しています。私はこれを取り除きたい。

SELECT 
    BILL_DETAIL.id AS BILLDETAILID, 
    BILL_HEADER.id AS BILLHEADERID, 
    adjustment.id adjustmentID 
FROM 
    BILLHEADER 
INNER JOIN 
    BILL_DETAIL ON BILL_DETAIL.billdetail2billhdr = BILLHEADER.id 
LEFT JOIN 
    adjustment ON adjustment.adjustment2bill_detail = BILLDETAIL.id 
INNER JOIN 
    incident ON incident.case2billhdr = BILLHEADER.id 

Answer 1

のための最初のadjustment.idを返します。この

WITH CTE 
AS 
(
    select 
    SeqNo = ROW_NUMBER() OVER(PARTITON BY BILL_DETAIL.id,BILL_HEADER.id ORDER BY adjustment.id DESC), 
    BILL_DETAIL.id as BILLDETAILID, 
    BILL_HEADER.id as BILLHEADERID, 
    adjustment.id adjustmentID 
    from BILLHEADER 
    Inner JOIN BILL_DETAIL ON BILL_DETAIL.billdetail2billhdr=BILLHEADER.id 
    left join adjustment on adjustment.adjustment2bill_detail=BILLDETAIL.id 
    inner join incident on incident.case2billhdr=BILLHEADER.id 
) 
SELECT 
    * 
    FROM CTE 
    WHERE SeqNo = 1 

をお試しくださいもう一度試してみてください：

select 
    BILL_DETAIL.id as BILLDETAILID, 
    BILL_HEADER.id as BILLHEADERID, 
    MAX(adjustment.id) as adjustmentID 
from BILLHEADER 
Inner JOIN BILL_DETAIL ON BILL_DETAIL.billdetail2billhdr=BILLHEADER.id 
left join adjustment on adjustment.adjustment2bill_detail=BILLDETAIL.id 
inner join incident on incident.case2billhdr=BILLHEADER.id 
group by BILL_DETAIL.id,BILL_HEADER.id 

select billdetailid, 
     billheadid, 
     adjustmentid 
from 
(SELECT 
    BILL_DETAIL.id AS BILLDETAILID, 
    BILL_HEADER.id AS BILLHEADERID, 
    adjustment.id adjustmentID, 
    row_number() over(partition by bill_detail.id, bill_header.id order by adjustment.id desc) rn 
FROM 
    BILLHEADER 
INNER JOIN 
    BILL_DETAIL ON BILL_DETAIL.billdetail2billhdr = BILLHEADER.id 
LEFT JOIN 
    adjustment ON adjustment.adjustment2bill_detail = BILLDETAIL.id 
INNER JOIN 
    incident ON incident.case2billhdr = BILLHEADER.id) t1 
where t1.rn = 1 

Answer 2

これは私が何を」理解だと思う各BILL_DETAIL.id + BILL_HEADER.idの組み合わせ

Answer 3

このスクリプトを試してください。

SELECT 
    BILL_DETAIL.id AS BILLDETAILID, 
    BILL_HEADER.id AS BILLHEADERID, 
    adjustment.id adjustmentID 
FROM 
    BILLHEADER 
INNER JOIN 
    incident ON incident.case2billhdr = BILLHEADER.id 
INNER JOIN 
    BILL_DETAIL ON BILL_DETAIL.billdetail2billhdr = BILLHEADER.id 
LEFT JOIN 
    adjustment ON adjustment.adjustment2bill_detail = BILLDETAIL.id 
INNER JOIN (
    SELECT MAX(adjustment.id) AS maxAdjustmentId, BILLDETAIL.id as BILLDETAIL_id FROM BILLDETAIL 
    INNER JOIN adjustment ON adjustment.adjustment2bill_detail = BILLDETAIL.id 
    GROUP BY BILLDETAIL.id 
) AS maxAdjusment on maxAdjusment.BILLDETAIL_id = BILLDETAIL.id AND maxAdjusment.maxAdjustmentId = adjustment.id
