Question

我有一个查询，该查询从GLTable返回当前和将来的收入。我需要返回两种发布类型。如果Postingtype A不存在，则返回Postingtype B，如果Postingtype A仅存在，则返回postingtypeA。DB为MSSQL 2014。

我尝试了以下几种变体，

WHERE (EXISTS (SELECT 1 FROM GLAccountPosting WHERE PostingType = 10) 
        )
        OR
        NOT EXISTS (SELECT 1 FROM GLAccountPosting WHERE PostingType = 14) 

        (;

WHERE 
postingtype in (14, 10)
AND
    (StartDateTime > '2019/07/01' AND postingtype = 10)
    OR
     (StartDateTime < '2019/07/01' AND postingtype = 14);

WHERE
    (StartDateTime > '2019/07/01' AND postingtype = 10 ) OR
    (StartDateTime < '2019/07/01' OR postingtype = 14);

以下查询（由于很大而被截断）：

SELECT 

prepay.Prepay,
Case When GAP.postingtype = 14 then isnull(sum(GAP.CreditValue),0) ELSE 0 end as CreditTodate,
Case When GAP.postingtype = 14 then prepay.Prepay -  isnull(sum(GAP.CreditValue),0) ELSE prepay.Prepay   end AS Balance,

GAP.PostingType

GLAccountPosting AS GAP

    JOIN (SELECT 

                        SalesTransactions.BranchID,
                        Departments.DepartmentGUID,
                        SalesTransactions.SalesTransactionGUID,
                        SalesTransactionDetails.SalesTransactionLineGUID,

                 WHERE  
                      (
                            SalesTransactionDetails.AccrualStatus = 1 OR SalesTransactionDetails.AccrualStatus=2 -- 1 = reversed, 2 = deferred
                      ) AND

                        SalesTransactionDetails.PrepayValue <> 0 AND
                        isnull(SalesTransactionLines.CreditSalesTransactionLineGUID,0x0) = 0x0  and -- remove credited lines      
                        SalesTransactions.status = 1 and -- remove not finalised and cancelled invoices
                        BookingLinesDetails.ItemType = 1 and  
                      (BookingLinesDetails.BookingDetailProgress not in (2,4) or 
                        (
                            BookingLinesDetails.BookingDetailProgress in (2,4) and SalesTransactionDetails.AccrualStatus <> 1)
                        ) 
                        and
                        (   
                            BookingLinesDetails.CalendarLinkGUID is null or 
                            (BookingLinesDetails.CalendarLinkGUID is not null and BookingLinesDetails.StartDateTime >= '2019/01/01'
                            )
                        ) 

                         -- include all sales tran details that are for bookings in the future
                         -- whether they have been completed or not and whether they have 

                        GROUP BY 
                            SalesTransactions.BranchID,
                            SalesTransactions.SalesTransactionGUID,
                            SalesTransactionDetails.SalesTransactionLineGUID,
                            Departments.DepartmentGUID,
                            BookingLinesDetails.StartDateTime) As prepay on prepay.SalesTransactionLineGUID = GAP.SalesTransactionLineGUID
                        JOIN salestransactionlines stl on stl.salestransactionlineguid = gap.salestransactionlineguid

                        LEFT JOIN salestransactiondetails sd on sd.SalesTransactiondetailGUID = GAP.SalesTransactiondetailGUID


where 
        GAP.ItemType = 1



group by


GAP.GLPostingDescription,
GAP.postingtype,
GAP.FormattedGLAccountCode,
prepay.Prepay,
GAP.PostingType

我需要的结果是：

Prepaid   Current Future  postingtype
26.90     0.00    26.90   10
215.20  215.20     0.00   14

每行都可能同时具有Postingtype 10和14，但我只想一次看到一个。如果两者都出现在同一笔交易中，则会使总计不正确。

Answer 1

这是你的意思吗？

DECLARE @t TABLE (TransactionID INT)
DECLARE @p TABLE (PostingType CHAR(1), TransactionID INT)

INSERT INTO @t
(TransactionID)
VALUES
(1),
(2),
(3)

INSERT INTO @p
(PostingType, TransactionID)
VALUES
('A', 1),
('B', 1),
('A', 2),
('B', 3)

SELECT t.TransactionID FROM @t t
WHERE
	EXISTS
		(
			SELECT 1 FROM @p p
			PIVOT  
			(  
			COUNT(p.PostingType)  
			FOR p.PostingType IN ([A], [B])  
			) sq
			WHERE
				(
					([A] = 0 AND [B] > 0) --Postingtype A does not exist then return postingtype B
					OR ([A] > 0 AND [B] = 0) --If postingtype A exists only return postingtype A
				)
				AND sq.TransactionID = t.TransactionID
		)

“如果查询返回B中不存在A，但是如果存在A仅返回A”的SQL语法
