Answer 1

Did you try dynamic SQL?

Something like this.... (UnTested)
DECLARE
v_user VARCHAR2(50);
BEGIN
EXECUTE IMMEDIATE 'select * from emp@' || v_user || 'llink';
END;In your case, the link name is based on the user, you can simplify it like this
DECLARE
v_user VARCHAR2(50);
BEGIN
EXECUTE IMMEDIATE 'select * from emp@' || LOWER(user) || 'llink';
END;You might need to use INTO clause for the select statements.
