lignes SQL à colonnes

Question

I ont au-dessous structure de table dans MS SQL

AirQuoteID  Name  SalesValue 
7     M   49.50 
7     N   23.10 
7     +45   233.20 
7     +100  233.20 
7     +250  2333.10 

Je veux une requête qui peut retourner

AirQuoteID  M  N  +45  +100 +250 
7    49.50 23.10 233.20  233.20 2333.10 

Quelle sera la solution optimale. Les valeurs sont dynamiques

Answer 1

Vous devez consulter l'opérateur PIVOT.

;With T As 
(
SELECT 7 AirQuoteID,'M' Name,49.50 SalesValue UNION ALL 
SELECT 7 AirQuoteID,'N', 23.10 UNION ALL 
SELECT 7 AirQuoteID,'+45',233.20 UNION ALL 
SELECT 7 AirQuoteID,'+100',233.20 UNION ALL 
SELECT 7 AirQuoteID,'+250',2333.10 
) 
SELECT AirQuoteID, [M], [N], [+45], [+100], [+250] 
FROM T 
PIVOT 
(
MAX(SalesValue) 
FOR Name IN ([M], [N], [+45], [+100], [+250]) 
) AS pvt; 

Toutefois, si les valeurs des colonnes ne sont pas fixes, vous aurez besoin d'utiliser dynamic SQL.

Answer 2

Comme les données est dynamique, pivot aidera pas

http://www.sqlteam.com/article/dynamic-cross-tabs-pivot-tables lien posté par @ Martin vraiment aidé.

d'abord créer la procédure ci-dessous

CREATE PROCEDURE [dbo].[crosstab] 
@select varchar(8000), 
@sumfunc varchar(100), 
@pivot varchar(100), 
@table varchar(100) 
AS 

DECLARE @sql varchar(8000), @delim varchar(1) 
SET NOCOUNT ON 
SET ANSI_WARNINGS OFF 

print ('SELECT ' + @pivot + ' AS [pivot] INTO ##pivot FROM ' + @table + ' WHERE 1=2') 
EXEC ('SELECT ' + @pivot + ' AS [pivot] INTO ##pivot FROM ' + @table + ' WHERE 1=2') 
EXEC ('INSERT INTO ##pivot SELECT DISTINCT ' + @pivot + ' FROM ' + @table + ' WHERE ' 
+ @pivot + ' Is Not Null') 

SELECT @sql='', @sumfunc=stuff(@sumfunc, len(@sumfunc), 1, ' END)') 

SELECT @delim=CASE Sign(CharIndex('char', data_type)+CharIndex('date', data_type)) 
WHEN 0 THEN '' ELSE '''' END 
FROM tempdb.information_schema.columns 
WHERE table_name='##pivot' AND column_name='pivot' 

SELECT @sql=@sql + '''' + convert(varchar(100), [pivot]) + ''' = ' + 
stuff(@sumfunc,charindex('(', @sumfunc)+1, 0, ' CASE ' + @pivot + ' WHEN ' 
+ @delim + convert(varchar(100), [pivot]) + @delim + ' THEN ') + ', ' FROM ##pivot 

DROP TABLE ##pivot 

SELECT @sql=left(@sql, len(@sql)-1) 
SELECT @select=stuff(@select, charindex(' FROM ', @select)+1, 0, ', ' + @sql + ' ') 

EXEC (@select) 
SET ANSI_WARNINGS ON 
GO 

La mention article na pas pour récupérer des données à partir d'une même table, donc ci-dessous comment vous le faites

EXECUTE crosstab 'select titles.AirQuoteID from AirSaleQuoteRateSlab titles 
        inner join 
        (select distinct AirQuoteID,[Name] from AirSaleQuoteRateSlab) sales 
        on (sales.AirQuoteID=titles.AirQuoteID) 
        group by titles.AirQuoteID', 'AVG(titles.SalesValue)','titles.Name','AirSaleQuoteRateSlab titles' 

Answer 3

select AirQuoteID, 
sum(case Name when 'M' then SalesValue else 0 end) 'M', 
sum(case Name when 'N' then SalesValue else 0 end) 'N', 
sum(case Name when '+45' then SalesValue else 0 end) '+45', 
sum(case Name when '+100' then SalesValue else 0 end) '+100', 
sum(case Name when '+250' then SalesValue else 0 end) '+250' 
from Table1 
group by AirQuoteID
