Answer 2

이것은 사용중인보고 도구에서 가장 잘 처리됩니다. '피벗 테이블'을 찾습니다.

첫 번째 테스트 데이터 :

Answer 3

select [AccountManager], ISNULL([Email],0) as [Email], ISNULL([Closing],0) as [Closing], ISNULL([Preparing Contact],0) as [Preparing Contact], ISNULL([Client Negotiation],0) as [Client Negotiation] from 
    (SELECT * FROM TestPivot) as SourceTable 

Pivot 
(
    SUM([Count]) 
    For [Action] in ([Email], [Closing], [Preparing Contact], [Client Negotiation]) 
) as PivotedColumns 
order by [Email] desc, [Closing] desc, [Preparing Contact] desc, [Client Negotiation] desc 

Answer 4

어쩌면 무언가를 따라

CREATE TABLE #tbl (AccountManager VARCHAR(100), Action VARCHAR(100),Count INT) 

INSERT INTO #tbl 
VALUES 
    ('Joe','Client Negotiation',10), 
    ('Bloggs','Closing',1), 
    ('Aunty','Email',12), 
    ('Marie','Preparing Contract',32) 

당신이 열 정적 인 것을 알고 있다면. 그럼 당신은이 작업을 수행 할 수 있습니다

먼저 고유 열 이름 : 동적 피벗과 같은 그런

DECLARE @cols VARCHAR(MAX), 
     @colsWithIsNull VARCHAR(MAX) 
;WITH CTE 
AS 
(
    SELECT 
     ROW_Number() OVER(PARTITION BY tbl.Action ORDER BY tbl.Action) AS iRank, 
     tbl.Action 
    FROM 
     #tbl AS tbl 
) 
SELECT @cols = COALESCE(@cols + ','+QUOTENAME(Action), 
        QUOTENAME(Action)), 
     @colsWithIsNull=COALESCE(@colsWithIsNull + ',ISNULL('+QUOTENAME(Action)+',0) AS '+QUOTENAME(Action), 
        'ISNULL('+QUOTENAME(Action)+',0) AS '+QUOTENAME(Action)) 
FROM 
    CTE 
WHERE 
    iRank=1 

:

SELECT 
    AccountManager, 
    ISNULL([Client Negotiation],0) AS [Client Negotiation], 
    ISNULL([Closing],0) AS [Closing], 
    ISNULL([Email],0) AS [Email], 
    ISNULL([Preparing Contract],0) AS [Preparing Contract] 
FROM 
(
SELECT 
    tbl.AccountManager, 
    tbl.Action, 
    tbl.Count 
FROM 
    #tbl AS tbl 
) AS p 
PIVOT 
(
    SUM([Count]) 
    FOR [Action] IN([Client Negotiation],[Closing],[Email],[Preparing Contract]) 
) AS pvt 

그렇지 않으면이 같은 동적 피벗을 할 필요가

DECLARE @query NVARCHAR(4000)= 
N'SELECT 
    AccountManager, 
    '+@colsWithIsNull+' 
FROM 
(
SELECT 
    tbl.AccountManager, 
    tbl.Action, 
    tbl.Count 
FROM 
    #tbl AS tbl 
) AS p 
PIVOT 
(
    SUM([Count]) 
    FOR [Action] IN('+@cols+') 
) AS pvt' 

EXECUTE(@query) 

내 경우에는 임시 테이블을 삭제합니다.

DROP TABLE #tbl
