Question

我有这两个选择陈述

SELECT SizeName,SUM(DESIGNSIZERELEASE.Quantity) as [Release]
FROM DESIGNRELEASE JOIN
     DESIGNSIZERELEASE
     ON DESIGNRELEASE.DesignReleaseID = DESIGNSIZERELEASE.DesignReleaseID JOIN
     SIZESET
     ON SIZESET.SizeSetID = DESIGNSIZERELEASE.SizeSetID AND
        DESIGNRELEASE.RevisionNo = SIZESET.RevisionNo
WHERE DESIGNRELEASE.RevisionNo = 2 AND DESIGNRELEASE.DesignID='SD00000'
GROUP BY DESIGNRELEASE.DesignID,Towhom,SizeName
ORDER BY case SizeName when 'XS' then 1 when 'S' then 2 when 'M' then 3 when 'L' then 4 when 'XL' then 5 end

AND

SELECT SUM(DESIGNRECEIVEDETAILS.Quantity) as [Receive]
FROM DESIGNRELEASE JOIN
     DESIGNSIZERELEASE
     ON DESIGNRELEASE.DesignReleaseID = DESIGNSIZERELEASE.DesignReleaseID JOIN
     SIZESET
     ON SIZESET.SizeSetID = DESIGNSIZERELEASE.SizeSetID AND
        DESIGNRELEASE.RevisionNo = SIZESET.RevisionNo JOIN
     DESIGNRECEIVE
     ON DESIGNRECEIVE.DesignReleaseID = DESIGNRELEASE.DesignReleaseID JOIN
     DESIGNRECEIVEDETAILS
     ON DESIGNRECEIVE.ReceiptID = DESIGNRECEIVEDETAILS.ReceiptID AND
        DESIGNRECEIVEDETAILS.SizeSetID = SIZESET.SizeSetID
WHERE DESIGNRELEASE.RevisionNo = 2 AND DESIGNRELEASE.DesignID='SD00000'
GROUP BY DESIGNRELEASE.DesignID,Towhom,SizeName
ORDER BY case SizeName when 'XS' then 1 when 'S' then 2 when 'M' then 3 when 'L' then 4 when 'XL' then 5 end

有这两个结果

+----------+-------------+    
|Size NAME |RELEASE      |
+----------+-------------+
|S         |20           |
+----------+-------------+
|M         |20           |
+----------+-------------+   

+----------+
|Receive   |
+----------+
|10        |
+----------+
|10        |
+----------+

我需要获得Release和Receive的区别我该怎么做？谢谢顺便说一下，我将它们分开了，因为当我把它们放在一个选择语句中时，我没有得到正确的结果

我不确定你是否可以在mysql中这样做，但这是你可以在Oracle中做的事情......

SELECT TABLE1.SizeName, TABLE1.Release, TABLE2.Receive, (TABLE1.Release - TABLE2.Receive) Difference
    FROM
    (SELECT SizeName, SUM(DESIGNSIZERELEASE.Quantity) as [Release] 
    FROM DESIGNRELEASE JOIN DESIGNSIZERELEASE ON DESIGNRELEASE.DesignReleaseID = DESIGNSIZERELEASE.DesignReleaseID 
    JOIN SIZESET ON SIZESET.SizeSetID = DESIGNSIZERELEASE.SizeSetID AND DESIGNRELEASE.RevisionNo = SIZESET.RevisionNo 
    WHERE DESIGNRELEASE.RevisionNo = 2 AND DESIGNRELEASE.DesignID='SD00000' 
    GROUP BY DESIGNRELEASE.DesignID,Towhom,SizeName 
    ORDER BY case SizeName when 'XS' then 1 when 'S' then 2 when 'M' then 3 when 'L' then 4 when 'XL' then 5 end) TABLE1
    ,
    (SELECT SizeName, SUM(DESIGNRECEIVEDETAILS.Quantity) as [Receive] 
    FROM DESIGNRELEASE JOIN DESIGNSIZERELEASE ON DESIGNRELEASE.DesignReleaseID = DESIGNSIZERELEASE.DesignReleaseID 
    JOIN SIZESET ON SIZESET.SizeSetID = DESIGNSIZERELEASE.SizeSetID AND DESIGNRELEASE.RevisionNo = SIZESET.RevisionNo 
    JOIN DESIGNRECEIVE ON DESIGNRECEIVE.DesignReleaseID = DESIGNRELEASE.DesignReleaseID 
    JOIN DESIGNRECEIVEDETAILS ON DESIGNRECEIVE.ReceiptID = DESIGNRECEIVEDETAILS.ReceiptID 
    AND DESIGNRECEIVEDETAILS.SizeSetID = SIZESET.SizeSetID WHERE DESIGNRELEASE.RevisionNo = 2 
    AND DESIGNRELEASE.DesignID='SD00000' GROUP BY DESIGNRELEASE.DesignID,Towhom,SizeName 
    ORDER BY case SizeName when 'XS' then 1 when 'S' then 2 when 'M' then 3 when 'L' then 4 when 'XL' then 5 end) TABLE2
    WHERE TABLE1.SizeName = Table2.SizeName

从2个返回多行的select语句中获得差异
