Question

Is it possible to construct a dynamic query to for a linked server (and if so how)?

For example:

@linkedServer varchar(50)
@var1 varchar(10)
@var2 varchar(10)

select * 
  from openquery(@linkedServer, 
                 'select c1,c2 
                    from t1 
                   where p1 = @var1 
                     and p2= @var2')

Answer 1

example

exec ('select * from openquery(' + @linkedServer + 
', ''select c1,c2 from t1 where p1 = '' + @var1 + ''and p2= '' + @var2 + ''')
