Data query using pivot encountered in SQL Server - sql-server

Question

I have a table with 3 nvarchar columns, 1 time column, and 2 columns Pass and Fail. I need to display the data by time column. On each milestone, there will be the number of Pass and Fail. I use Pivot and its only output Pass result without Fail. I tried everything. Please help
This is the input data:
Col1 Col2 Col3 Time Pass Fail
------------------------------------
A B C 08:30 80 0
A B C 09:30 60 2
A B C 10:30 80 0
A B C 11:30 70 0
I'm using this code:
DECLARE #cols AS NVARCHAR(MAX),
#query AS NVARCHAR(MAX)
SELECT
#cols = STUFF((SELECT ',' + QUOTENAME(Time)
FROM Your_Table
GROUP BY Time
ORDER BY Time
FOR XML PATH(''), TYPE).value('.', 'NVARCHAR(MAX)'), 1, 1, '')
SET #query = 'SELECT Col1,Col2,Col3,' + #cols + ' from
(
SELECT Col1,Col2,Col3,Time,Pass,Fail
from TD_SanLuong_CN
) x
pivot
(
sum(Pass)
for Time in (' + #cols + ')
) p1
pivot
(
sum(Fail)
for Time in (' + #cols + ')
) p2'
execute(#query);
Can I not use pivot to Fail?
I need output result:
Col1 Col2 Col3 08:30_Pass 08:30_Fail 09:30_Pass 09:30_Fail ...
A B C 80 0 60 2
Please help. Thank you!

Hi have a look at this code, i think this what you exactly needed as you expected Output
IF OBJECT_ID('tempdb..#Temp') IS NOT NULL
Drop table #Temp
CREATE TABLE #Temp (
Col1 CHAR(1),
Col2 CHAR(1),
Col3 CHAR(1),
[Time] TIME(0),
Pass INT,
Fail INT
);
INSERT #Temp (Col1, Col2, Col3, [Time], Pass, Fail) VALUES
('A', 'B', 'C', '08:30', 80, 0),
('A', 'B', 'C', '09:30', 60, 2),
('A', 'B', 'C', '10:30', 80, 0),
('A', 'B', 'C', '11:30', 70, 0);
DECLARE #cols AS NVARCHAR(MAX),
#query AS NVARCHAR(MAX),
#cols2 AS NVARCHAR(MAX),
#cols3 AS NVARCHAR(MAX),
#Dyncols AS NVARCHAR(MAX)
SELECT
#cols = STUFF((SELECT ',' + QUOTENAME(Time)
FROM #Temp
GROUP BY [Time]
ORDER BY [Time]
FOR XML PATH(''), TYPE).value('.', 'NVARCHAR(MAX)'), 1, 1, '')
SELECT
#cols2 = STUFF((SELECT ',' + 'MAX('+QUOTENAME(Time)+')' +' As '+ '['+CAST((Time) AS VARCHAR)+'_Pass'+']'
FROM #Temp
GROUP BY [Time]
ORDER BY [Time]
FOR XML PATH(''), TYPE).value('.', 'NVARCHAR(MAX)'), 1, 1, '')
SELECT
#cols3 = STUFF((SELECT ',' + 'MAX('+QUOTENAME(Time)+')' +' As '+ '['+CAST((Time) AS VARCHAR)+'_Fail'+']'
FROM #Temp
GROUP BY [Time]
ORDER BY [Time]
FOR XML PATH(''), TYPE).value('.', 'NVARCHAR(MAX)'), 1, 1, '')
SELECT
#Dyncols = STUFF((SELECT ',' + '['+CAST((Time) AS VARCHAR)+'_Pass'+']'+','+'['+CAST((Time) AS VARCHAR)+'_Fail'+']'
FROM #Temp
GROUP BY [Time]
ORDER BY [Time]
FOR XML PATH(''), TYPE).value('.', 'NVARCHAR(MAX)'), 1, 1, '')
SET #query=';with cte
AS
(
SELECT Col1,Col2,Col3,'+#cols2+' From
(
SELECT Col1,Col2,Col3,Time,Pass,Fail
FROM #Temp
) AS X
PIVOT
(
SUM(Pass)
FOR [Time] IN ('+#cols+' )
) p1
Group by Col1,Col2,Col3
),Cte2
AS
(
SELECT '+#cols3+' From
(
SELECT Col1,Col2,Col3,Time,Pass,Fail
from #Temp
) x
PIVOT
(
SUM(Fail)
FOR Time IN ('+#cols+')
)p1
Group by Col1,Col2,Col3
)
SELECT Col1,Col2,Col3,'+#Dyncols+' FROM cte ,Cte2'
PRINT #query
EXEC(#query)
Result
Col1 Col2 Col3 08:30:00_Pass 08:30:00_Fail 09:30:00_Pass 09:30:00_Fail 10:30:00_Pass 10:30:00_Fail 11:30:00_Pass 11:30:00_Fail
A B C 80 0 60 2 80 0 70 0
