3   Eraser   Quantity   200

但我想要显示如下

ID    Name     Amount     Quantity

2     Pencil   5/-        280
3     Eraser   7/-        200

Answer 1

在sql-server中::试试这个

select * from [dbo].[2]
pivot
(
max(value)
for condition in([amount],[quantity]) 
)as piv order by id

Answer 2

你可以这样做。

SELECT A.ID, A.Name, A.Value AS 'Amount', B.Value AS 'Quantity'
FROM (SELECT * FROM NewDemo WHERE Condition = 'Amount') AS A
    JOIN (SELECT * FROM NewDemo WHERE Condition = 'Quantity') AS B
    ON A.ID = B.ID

Answer 3

SELECT a.ID, a.Name, a.Value as Amount, b.Value as Quantity FROM 
(SELECT ID, Name, Value FROM NewDemo WHERE Condition = 'Amount') a 
LEFT JOIN (SELECT ID, Name, Value FROM NewDemo WHERE Condition = 'Quantity') b 
on a.ID = b.ID

Answer 4

嗨，我认为这会对你有所帮助

SELECT     ID, Name, MAX(DISTINCT CASE WHEN Condition = 'Amount' THEN Value END) AS   Amount, MAX(DISTINCT CASE WHEN Condition = 'Quantity' THEN Value END) 
           AS Quantity
FROM       dbo.TESTTABLE
GROUP BY   ID, Name

将sql表行显示为列
