需要帮助SQL Server游标
我有这张桌子：
我想要这个输出：
我正在使用此代码
DECLARE @InvoiceNo Varchar(100)
SET @InvoiceNo = '17-18/1003'
DECLARE @srNO Varchar(100)
PRINT @InvoiceNo
BEGIN
CREATE TABLE #tempTableNew
(
SrNO Varchar(100),
Description Varchar(100),
Qnty Varchar(100),
Unit Varchar(100),
Rate Varchar(100),
Amount Varchar(100)
)
DECLARE CREATFINALTABLE CURSOR FOR
SELECT
ROW_NUMBER() OVER(ORDER BY B.InvoiceNo ASC) AS 'SrNo'
FROM
Billing B
INNER JOIN
Furniture F on F.FurnitureID = B.ProductID
WHERE
B.InvoiceNo = @InvoiceNo
OPEN CREATFINALTABLE
FETCH NEXT FROM CREATFINALTABLE INTO @srNO
WHILE @@FETCH_STATUS = 0
BEGIN
SELECT
CONVERT(varchar, @srNO) AS 'SrNo',
F.FurnitureName AS 'Description',
CONVERT(varchar, B.Quantity) AS 'Qnty',
CONVERT(varchar, U.UnitName) AS 'Unit',
CONVERT(varchar, B.Rate) AS 'Rate',
CONVERT(varchar, B.Amount) AS 'Amount'
INTO
#tempTable
FROM
Billing B
INNER JOIN
Furniture F on F.FurnitureID = B.ProductID
INNER JOIN
UnitMaster U ON U.UnitID = B.UnitID
WHERE
B.BillingID = @srNO
INSERT INTO #tempTableNew
SELECT *
FROM #tempTable
WHERE SrNo = @srNO
UNION ALL
SELECT
(@srNO) AS 'srNo',
('SIZE: ' + CONVERT(varchar, Length) + ' X' +
CONVERT(varchar, Breadth) + ' X' + CONVERT(varchar, Height)) AS '[Description]',
' ' AS 'Qnty', ' ' AS 'Unit', ' ' AS 'Rate', ' ' AS 'Amount'
FROM Billing
WHERE BillingID = @srNO
UNION ALL
SELECT
(@srNO) AS 'srNo',
'SPECS:' AS '[Description]',
' ' AS 'Qnty', ' ' AS 'Unit', ' ' AS 'Rate', ' ' AS 'Amount'
FROM #tempTable
WHERE SrNo = @srNO
FETCH NEXT FROM CREATFINALTABLE INTO @srNO
DROP TABLE #tempTable
END
SELECT *
INTO #formated
FROM #tempTableNew
SELECT * FROM #formated
DROP TABLE #tempTableNew
DROP Table #formated
CLOSE CREATFINALTABLE
DEALLOCATE CREATFINALTABLE
END
我得到了这个输出。请帮我获得所需的输出。我想根据AreaOfUsage组显示记录。帮我修改这个光标，以便我可以获得所需的输出。提前谢谢..

答案 0 :(得分：1)
这种程度的数据操作并不适合SQL，并且通常会在表示层中执行＆＃34;但是这里有一种方法，你可能会觉得有用，根本不需要使用光标。它使用CROSS APPLY和VALUES代替，它为每个输入行创建多行输出。 VALUES区域的视觉布局易于控制。
已修订的答案
以SQL Fiddle作为演示提供。
MS SQL Server 2014架构设置：
CREATE TABLE Product
([SrNo] int, [Description] varchar(100), [Size] varchar(100)
, [Specs] varchar(100), [Qnty] int, [Unit] varchar(5)
, [Rate] int, [Amount] int, [AreaOfUsage] varchar(100))
;
INSERT INTO Product
([SrNo], [Description],[Size], [Specs], [Qnty], [Unit], [Rate], [Amount], [AreaOfUsage])
VALUES
(1, 'Bed as per design and detail', 'test iu','7.00x4.00x2.00', 1, 'P.RFT', 35000, 35000, 'Bedroom'),
(2, 'Coffee Table as per design and detail', 'shdjh test','7.00x3.00x2.00', 1, 'P.RFT', 12500, 12500, 'Hall'),
(3, 'Day Bed as per design in white', 'day bed test','7.00x5.00x3.00', 1, 'P.RFT', 19630, 19630, 'Bedroom')

原始回复
请注意，由于您没有提供示例数据，因此我的列不是所有varchar所以我已经使用CONCAT（...，＆＃39;＆＃39;）来转换每个非varchar列到varchar。请参阅此处的演示：SQL Fiddle
<强>设置：
CREATE TABLE Ihavethistable
([SrNo] int, [Description] varchar(17), [Specs] varchar(12), [Qnty] int, [Unit] varchar(5), [Rate] int, [Amount] int, [AreaOfUsage] varchar(7))
;
INSERT INTO Ihavethistable
([SrNo], [Description], [Specs], [Qnty], [Unit], [Rate], [Amount], [AreaOfUsage])
VALUES
(1, 'bed as per...', 'test iu', 1, 'P.RFT', 35000, 35000, 'Bedroom'),
(2, 'coffee table...', 'shdjh test', 1, 'P.RFT', 12500, 12500, 'Hall'),
(3, 'day bed as per...', 'day bed test', 1, 'P.RFT', 19630, 19630, 'Bedroom')
