在動態數據透視表中計數小計和總數

Question

我試圖在動態數據透視表中創建總計和小計的查詢。

我有3列的表格：

如何獲得導致這樣？

這是查詢我有，但我不能創建和總量小計：

DECLARE @Columns as VARCHAR(MAX) 

SELECT @Columns = 
COALESCE(@Columns + ', ','') + QUOTENAME(item) 
from @mytable 

DECLARE @SQL as VARCHAR(MAX) 
SET @SQL = 
'SELECT name, location, ' + @Columns + ' 
FROM 
(
    SELECT name, location, item 
    FROM @mytable 

) as PivotData 
PIVOT 
(
    count(item) 
    for item IN (' + @Columns + ') 
) AS PivotResult 
' 

EXEC(@SQL) 

我感謝您的幫助，謝謝。

另一種方式來做到這一點使用ROLLUP和GROUPING

DECLARE @Pivot_Columns AS VARCHAR(MAX), 
     @select_Columns VARCHAR(max) 

SELECT @Pivot_Columns = Stuff((SELECT DISTINCT ',' + Quotename(item) FROM #SampleData FOR xml path('')), 1, 1, '') 
SELECT @select_Columns = Stuff((SELECT DISTINCT ',Sum(' + Quotename(item) + ') as '+Quotename(item) FROM #SampleData FOR xml path('')), 1, 1, '') 

DECLARE @SQL AS VARCHAR(MAX) 

SET @SQL = 'SELECT case when grouping(location) = 1 and grouping(name) = 0 then ''Total''+ '' '' + name 
when grouping(location) = 1 and grouping(name) = 1 then ''Total'' 
else name end Name, location, ' 
      + @select_Columns + ' 
FROM 
(
    SELECT name, location, item 
    FROM #SampleData 

) as PivotData 
PIVOT 
(
    count(item) 
    for item IN (' 
      + @Pivot_Columns + ') 
) AS PivotResult 
group by name,location with rollup 
' 

EXEC(@SQL)

注：我已在你是如何串聯行到逗號分隔值的變化。您當前的字符串連接方法不能保證一直工作。我已經使用For Xml Path('')方法進行串接。

你可以使用GROUP BY GROUPING SETS計算Total item前Pivot

CREATE TABLE #SampleData 
(
    Name varchar(10), 
    Location varchar(20), 
    Item varchar(10) 
) 

INSERT INTO #SampleData 
VALUES 
('Ron', 'Loc A', 'Pencil'), 
('Ron', 'Loc A', 'Pencil'), 
('Ron', 'Loc B', 'Pen'), 
('Ron', 'Loc B', 'Laptop'), 
('Tom', 'Loc A', 'Pencil'), 
('Tom', 'Loc B', 'Pencil'), 
('Tom', 'Loc B', 'Pen'), 
('Tom', 'Loc A', 'Pencil'), 
('Tom', 'Loc A', 'Laptop'), 
('Tom', 'Loc A', 'Pencil') 


DECLARE @Columns as VARCHAR(MAX) 

SELECT @Columns = 
COALESCE(@Columns + ', ','') + QUOTENAME(sd.item) 
from (select DISTINCT item from #SampleData) sd 

DECLARE @SQL as VARCHAR(MAX) 
SET @SQL = 
'SELECT name, location, ' + @Columns + ' 
FROM 
(
    SELECT CASE WHEN sd.Location is null then ''Total '' + sd.Name 
      ELSE sd.Name 
      END as Name, 
      sd.Name as GroupName, 
      sd.Location, sd.item, count(item) AS CountValue 
    FROM #SampleData sd 
    GROUP BY GROUPING SETS ((sd.Name, sd.Location, sd.item),(sd.Name, sd.item)) 

) as PivotData 
PIVOT 
(
    sum(CountValue) 
    for item IN (' + @Columns + ') 
) AS PivotResult 
Order by GroupName, name 
' 

EXEC(@SQL) 

DROP TABLE #SampleData
