Question

方案：：我有一个用于薪金头的主表，即Basic，HRA，Cnveyance ...等。[Columns are : ID, SalaryHeadName]

和1个交易表，用于保存每个候选人的薪水记录。 [Columns are : CandidateID, SalaryHeadID, Amount]

现在，我想在候选人的个人资料页面上列出所有薪水头，用户将在其中看到“所有头”以及在这些头前面的可编辑文本框。

如果交易表中包含该特定候选人的特定薪金总额，我将填写该金额，否则文本框将为空白。

直到现在我的查询：

WITH cte as
(
Select ID,SalaryHeadName, Amount, DENSE_RANK () over (order by SalaryHeadName desc) as DenseRank 
from VW_GetSalaryStructureData 
where CandidateID = 145 or CandidateID is null 
GROUP BY  ID,SalaryHeadName,Amount

)

SELECT
    ID,SalaryHeadName, Amount, COUNT(Amount) as cnt
FROM
    cte
GROUP BY
    ID,SalaryHeadName, Amount

从两个表中采样数据：

现在，我要删除具有NULL值的重复行，并且仅列出所有SalaryHeads一次。

所需结果： I want to remove red highlighted rows from result if Candidate is having amount in transaction table, otherwise all heads with null amount, Please click here to see

Desired result on HTML page, I am developing in MVC 5

Answer 1

以下查询应返回预期结果。

BEGIN

WITH cte as ( Select ID,SalaryHeadName, Amount, DENSE_RANK () over (order by SalaryHeadName desc) as DenseRank  from VW_GetSalaryStructureData  where CandidateID = 145 or CandidateID is null  GROUP BY  ID,SalaryHeadName,Amount

)

SELECT
    ID,SalaryHeadName, Amount, COUNT(Amount) as cnt INTO #RESULT_TABLE FROM
    cte GROUP BY
    ID,SalaryHeadName, Amount;

WITH RM_DUPL AS 
(SELECT ROW_NUMBER OVER(PARTITION BY ID ORDER BY AMOUNT NULLS LAST) AS RN,  ID,SalaryHeadName, Amount, cnt FROM #RESULT_TABLE) SELECT  FROM RM_DUPL  WHERE RN = 1 or AMOUNT IS NOT NULL; END;

Answer 2

并非所有人都知道UNION运算符删除了重复项。当您想删除重复数据时，这很方便。如下：

 SELECT ColA, ColB, ColC
 FROM TableWithDuplicates
 UNION
 SELECT ColA, ColB, ColC
 FROM TableWithDuplicates

Result是TableWithDuplicates的重复数据删除结果集。

Answer 3

我希望以下查询能够满足您在“期望的输出图像”中提到的需求。

SELECT SH.Id SalaryHeadId, SH.SalaryHeadName, ISNULL(Tr.Amount, 0.00) PerMonth, 
ISNULL(Tr.Amount, 0.00)*12 PerAnnum
FROM Sal_Head SH
LEFT JOIN Transaction_Table Tr ON SH.Id = Tr.SalaryHeadId
WHERE Tr.CandidateId = 145

从左表获取所有行，并根据其他列的值删除重复的行
