在pivot聚合函数中使用CONCAT函数时发生SQL Server错误

我想做的是添加一个 CONCAT 作用于 pivot

“CONCAT”不是可识别的聚合函数。

SELECT * FROM (
SELECT dateadd(minute,(datediff(minute,0,Time)/15)*15,0) Time,  AREA, COUNT(BLOB) BLOBs, CARS
FROM 
(SELECT BLOB, Time, CARS, DRIVER, [MK], AREA, Tier FROM (
SELECT [BLOB Nbr] BLOB, Time, CARS, [From PT], [To PT], [From PN], [To PN], DRIVER, [MK],
CASE AREA
WHEN '01' THEN '02' WHEN '03' THEN '02'
WHEN '05' THEN '06' WHEN '07' THEN '06'
WHEN '09' THEN '10' WHEN '11' THEN '10'
ELSE AREA END AREA, 
Position, Tier
FROM (
SELECT [BLOB Nbr], T_IME Time, [C NAME] CARS, [From PT], [To PT], [From PN], [To PN], [C V] DRIVER, [MK],
CASE WHEN [From PT] = 'DRIVER' THEN LEFT(RIGHT([From PN],6),2) ELSE LEFT(RIGHT([To PN],6),2) END AREA,
CASE WHEN [From PT] = 'DRIVER' THEN LEFT(RIGHT([From PN],4),2) ELSE LEFT(RIGHT([To PN],4),2) END Position,
CASE WHEN [From PT] = 'DRIVER' THEN RIGHT([From PN],2) ELSE RIGHT([To PN],2) END Tier
FROM mytable c
WHERE ([From PT] = 'DRIVER' OR [To PT] = 'DRIVER')
) a ) b ) c
GROUP BY dateadd(minute,(datediff(minute,0,Time)/15)*15,0),  AREA, CARS) src pivot(CONCAT(sum(BLOBs),CARs) for AREA in ([02],[06],[10])) piv;

如果我将第二行更改为(删除 CARs ):

SELECT dateadd(minute,(datediff(minute,0,Time)/15)*15,0) Time,  AREA, COUNT(BLOB) BLOBs

如果我改变主意 GROUP BY 汽车 海螺 功能):

GROUP BY dateadd(minute,(datediff(minute,0,Time)/15)*15,0),  AREA) src pivot(sum(BLOBs) for AREA in ([02],[06],[10])) piv;

它可以工作,但我希望在结果中连接。

试试这个,

CREATE TABLE #PIVOT (Time  DATETIME, AREA INT, BLOBs INT, CARs VARChar (10))

insert into #PIVOT values 
 ('2018-05-07 16:00:00.000', 02, 11     ,'BMW')
,('2018-05-07 16:15:00.000', 02, 2      ,'BMW')
,('2018-05-07 16:15:00.000', 06, 7      ,'KIA')
,('2018-05-07 16:30:00.000', 06, 8      ,'KIA')
,('2018-05-07 16:45:00.000', 02, 9      ,'BMW')
,('2018-05-07 17:00:00.000', 02, 9      ,'BMW')
,('2018-05-07 17:00:00.000', 10, 8      ,'FIA')


select
 Time, CARs + convert (varchar (10), [02]) [02]
 , CARs + convert (varchar (10), [06]) [06], CARs + convert (varchar (10), [10]) [10]
from (
 select
 *
 from #PIVOT
) p
pivot
(
max (BLOBs) for area in ([02],[06], [10])
) t

Time                        02      06      10

您可以在下面尝试—您需要在pivot中使用聚合函数,以便在您的情况下可以使用 max(CONCAT(sum(BLOBs),CARs))

    SELECT * FROM (
SELECT dateadd(minute,(datediff(minute,0,Time)/15)*15,0) Time,  AREA, COUNT(BLOB) BLOBs, CARS
FROM 
(SELECT BLOB, Time, CARS, DRIVER, [MK], AREA, Tier FROM (
SELECT [BLOB Nbr] BLOB, Time, CARS, [From PT], [To PT], [From PN], [To PN], DRIVER, [MK],
CASE AREA
WHEN '01' THEN '02' WHEN '03' THEN '02'
WHEN '05' THEN '06' WHEN '07' THEN '06'
WHEN '09' THEN '10' WHEN '11' THEN '10'
ELSE AREA END AREA, 
Position, Tier
FROM (
SELECT [BLOB Nbr], T_IME Time, [C NAME] CARS, [From PT], [To PT], [From PN], [To PN], [C V] DRIVER, [MK],
CASE WHEN [From PT] = 'DRIVER' THEN LEFT(RIGHT([From PN],6),2) ELSE LEFT(RIGHT([To PN],6),2) END AREA,
CASE WHEN [From PT] = 'DRIVER' THEN LEFT(RIGHT([From PN],4),2) ELSE LEFT(RIGHT([To PN],4),2) END Position,
CASE WHEN [From PT] = 'DRIVER' THEN RIGHT([From PN],2) ELSE RIGHT([To PN],2) END Tier
FROM mytable c
WHERE ([From PT] = 'DRIVER' OR [To PT] = 'DRIVER')
) a ) b ) c
GROUP BY dateadd(minute,(datediff(minute,0,Time)/15)*15,0),  AREA, CARS) src pivot(max(CONCAT(sum(BLOBs),CARs)) for AREA in ([02],[06],[10])) piv;
