Може би нещо подобно:
Първо данните от теста:
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)
Ако знаете, че колоните са статични. Тогава можете да направите следното:
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
В противен случай трябва да направите динамичен пивот като този:
Първо уникалните имена на колони:
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
След това динамичната опорна точка като тази:
DECLARE @query NVARCHAR(4000)=
N'SELECT
AccountManager,
'[email protected]+'
FROM
(
SELECT
tbl.AccountManager,
tbl.Action,
tbl.Count
FROM
#tbl AS tbl
) AS p
PIVOT
(
SUM([Count])
FOR [Action] IN('[email protected]+')
) AS pvt'
EXECUTE(@query)
Тогава в моя случай ще премахна временната таблица:
DROP TABLE #tbl
