Then the best may be to have a stored procedure in the other database
to retreive that data. You still need to construct the procedure name
dynamically, but since EXEC accepts a variable for the procedure name,
you don't have to use dynamic SQL.
That is you can say:
SELECT @sp_name = @dbname + '..that_sp'
EXEC @sp_name
