use
outer/cross apply
:select *
from Employee as E
cross apply dbo.[StateFixedTaxesCalculation](3020, E.EmployeeId, 1, 1006) as TC
se você ainda precisar filtrar por
TC.EmployeeId =E.EmployeeId
, você pode fazer isso com a subconsulta:select *
from Employee as E
cross apply (
select TT.*
from dbo.[StateFixedTaxesCalculation](3020, E.EmployeeId, 1, 1006) as TT
where TT.EmployeeId = E.EmployeeId
) as TC
