SQL & PL/SQL

Hi,

i have requirement, to create a dblink, then i have to create a synonym on it.

Ex:

CREATE DATABASE LINK "xyz.abc.COM@asdf"
   CONNECT TO "user1" IDENTIFIED BY VALUES ':1'
   USING 'xyz.abc.COM';

I can get the data from using above db link.

select * from table1@xyz.abc.COM@asdf;

But after creating dblink, how to create a synonym on it, and how to select data from that synonym.
