Hi all,

select u_emp,(select name from [@emp] where code=u_emp) name1
from ovpm
This query gives me the output having employee code and name.
I want to further filter the employee name by giving a where clause as
where name1='Carell'

Is it possible?
Please Help

Yes and I would rather prefer JOIN over Subquery:

select o.u_emp, e.name 
from ovpm o JOIN [@emp] e on e.code = o.u_emp
where e.name = 'Carell'

You should use JOIN as suggested. Otherwise your query will lead to error if subquery returns more than one value
