Remove duplicate rows displayed in pivot - sql

Question

Basically, I have created a pivot query wherein it will display the total_work_hours per each costcode for each employee.
This is my desired output:
employeeno 8322.170 10184.2648 8321.169 10184.2649 <- costcodes
--------------------------------------------------------------------------
080418 10.00 1.50 NULL NULL
080441 6.50 NULL 1.00 3.00
but this is the result of my query:
employeeno 8322.170 10184.2648 8321.169 10184.2649 <- costcodes
--------------------------------------------------------------------------
080418 10.00 NULL NULL NULL
080418 NULL 1.50 NULL NULL
080441 NULL NULL 1.00 NULL
080441 6.50 NULL NULL NULL
080441 NULL NULL NULL 3.00
This is the result of my inner query:
employeeno costcoding hour_per_costcode
--------------------------------------------------
PH080418 8322.170 10.00
PH080418 10184.2648 1.50
PH080441 8321.169 1.00
PH080441 8322.170 6.50
PH080441 10184.2649 3.00
This is my query:
WITH PivotData AS
(SELECT wa.id,wa.sitecode, wa.companycode, wa.startdate, wa.enddate,
wa.description, wa.ratetypeid, wa_details.employeeno,
CAST(wa_details.costcode AS NVARCHAR(MAX)) + '.' +
CAST(wa_details.subcostcode AS NVARCHAR(MAX)) costcoding ,
wa_details.subcostcode, wa_details.hrswork [hour_per_costcode],
view_ttl_hours.ttl_work_hrs
FROM workallocation wa
INNER JOIN workallocation_details wa_details
ON wa.id = wa_details.workallocationid
INNER JOIN
(SELECT SUM(ttl_work_hrs) ttl_work_hrs, employee_id
FROM vwu_SUM_TIMESHEET_DAILY
WHERE TKSDATE BETWEEN '02-09-2012' AND '02-09-2012'
GROUP BY employee_id
) view_ttl_hours
ON wa_details.employeeno=view_ttl_hours.employee_id WHERE wa.id=99
)
SELECT employeeno, [8322.170], [10184.2648], [8321.169], [10184.2649]
FROM PivotData
PIVOT (MAX([hour_per_costcode])
FOR costcoding
IN ([8322.170], [10184.2648], [8321.169], [10184.2649])
) AS PivotResult
ORDER BY employeeno;
My question is how will I be able to unite the value for my multiple rows so that my desire output will be achieve? I also try the cross tab query but the result is also the same.
I need some guidance on how to solve this; can you help?

Remove the columns you don't need from the CTE. Something like this should work for you.
WITH PivotData AS
(SELECT wa_details.employeeno,
CAST(wa_details.costcode AS NVARCHAR(MAX)) + '.' +
CAST(wa_details.subcostcode AS NVARCHAR(MAX)) costcoding ,
wa_details.subcostcode, wa_details.hrswork [hour_per_costcode]
FROM workallocation wa
INNER JOIN workallocation_details wa_details
ON wa.id = wa_details.workallocationid
INNER JOIN
(SELECT SUM(ttl_work_hrs) ttl_work_hrs, employee_id
FROM vwu_SUM_TIMESHEET_DAILY
WHERE TKSDATE BETWEEN '02-09-2012' AND '02-09-2012'
GROUP BY employee_id
) view_ttl_hours
ON wa_details.employeeno=view_ttl_hours.employee_id WHERE wa.id=99
)
SELECT employeeno, [8322.170], [10184.2648], [8321.169], [10184.2649]
FROM PivotData
PIVOT (MAX([hour_per_costcode])
FOR costcoding
IN ([8322.170], [10184.2648], [8321.169], [10184.2649])
) AS PivotResult
ORDER BY employeeno;
Above query with your data:
WITH PivotData AS
(select 'PH080418' as employeeno, 8322.170 as costcoding, 10.00 as hour_per_costcode union all
select 'PH080418', 10184.2648, 1.50 union all
select 'PH080441', 8321.169, 1.00 union all
select 'PH080441', 8322.170, 6.50 union all
select 'PH080441', 10184.2649, 3.00
)
SELECT employeeno, [8322.170], [10184.2648], [8321.169], [10184.2649]
FROM PivotData
PIVOT (MAX([hour_per_costcode])
FOR costcoding
IN ([8322.170], [10184.2648], [8321.169], [10184.2649])
) AS PivotResult
ORDER BY employeeno;
Result:
employeeno 8322.170 10184.2648 8321.169 10184.2649
---------- ---------- ------------ ---------- -----------
PH080418 10.00 1.50 NULL NULL
PH080441 6.50 NULL 1.00 3.00
