Would like to return a fake row if there is no match to my pair (for a year) - sql

Question

I would like to clean up some data returned from a query. This query :
select seriesId,
startDate,
reportingCountyId,
countyId,
countyName,
pocId,
pocValue
from someTable
where seriesId = 147
and pocid = 2
and countyId in (2033,2040)
order by startDate
usually returns 2 county matches for all years:
seriesId startDate reportingCountyId countyId countyName pocId pocValue
147 2004-01-01 00:00:00.000 6910 2040 CountyOne 2 828
147 2005-01-01 00:00:00.000 2998 2033 CountyTwo 2 4514
147 2005-01-01 00:00:00.000 3000 2040 CountyOne 2 2446
147 2006-01-01 00:00:00.000 3018 2033 CountyTwo 2 5675
147 2006-01-01 00:00:00.000 4754 2040 CountyOne 2 2265
147 2007-01-01 00:00:00.000 3894 2033 CountyTwo 2 6250
147 2007-01-01 00:00:00.000 3895 2040 CountyOne 2 2127
147 2008-01-01 00:00:00.000 4842 2033 CountyTwo 2 5696
147 2008-01-01 00:00:00.000 4846 2040 CountyOne 2 2013
147 2009-01-01 00:00:00.000 6786 2033 CountyTwo 2 2578
147 2009-01-01 00:00:00.000 6817 2040 CountyTwo 2 1933
147 2010-01-01 00:00:00.000 6871 2040 CountyOne 2 1799
147 2010-01-01 00:00:00.000 6872 2033 CountyTwo 2 4223
147 2011-01-01 00:00:00.000 8314 2033 CountyTwo 2 3596
147 2011-01-01 00:00:00.000 8315 2040 CountyOne 2 1559
But note please that the first entry has only CountyOne for 2004. I would like to return a fake row for CountyTwo for a graph I am doing. It would be sufficient to fill it like CountyOne only with pocValue = 0.
thanks!!!!!!!!

Answer 1

Try this (if you need blank row for that countryid)
; with CTE AS
(SELECT 2033 As CountryID UNION SELECT 2040),
CTE2 AS
(
seriesId, startDate, reportingCountyId,
countyId, countyName, pocId, pocValue
from someTable where
seriesId = 147 and pocid = 2 and countyId in (2033,2040)
order by startDate
)
SELECT x1.CountyId, x2.*, IsNull(pocValue,0) NewpocValue FROM CTE x
LEFT OUTER JOIN CTE2 x2 ON x1.CountyId = x2.reportingCountyId
