With CTE's:
WITH CTE_Count1 (ProjectId, Counter)
AS (SELECT ProjectId, COUNT(1)
         FROM Table1Name
         GROUP BY ProjectId),
CTE_Count2 (ProjectId, Counter)
AS (SELECT ProjectId, COUNT(1)
         FROM Table2Name
         GROUP BY ProjectId)

SELECT P.ProjectId, P.ProjectName
FROM ProjectTable P
    INNER JOIN CTE_Count1 C1 ON P.ProjectId = C1.ProjectId
    INNER JOIN CTE_Count1 C2 ON P.ProjectId = C2.ProjectId
WHERE C1.Counter > C2.Counter

an easy way would be:

select *
from (
   SELECT ProjectId,ProjectName, CntP1=(select count(*) from ....), CntP2=(SELECT count(*) from...)
   From ProjectTable
) AS A
where CntP1 > CntP2

hELLO,

You can use Having clause to compare the aggregated columns

SELECT ProjectId,ProjectName, CntP1=(select count(*) from ....), CntP2=(SELECT count(*) from...)
From ProjectTable 
group by ProjectId,ProjectName
having (select count(*) from ....t1) > (select count(*) from ....t2)
