SQL & PL/SQL :: Copy Into Same Table / Recursive Rename Of Duplicates

In MS Windows, if I copy a file and paste it into the same folder, I get a copy with the text 'Copy of' in front of the file name. If I paste it again, I get another copy with a different version number.

E.g.
sqlnet.log
Copy of sqlnet.log
Copy (1) of sqlnet.log
Copy (2) of sqlnet.log

I was wondering if I could copy existing rows into a table and do the same thing?

So, for example if I had this table:

create table tst_srch (srch_is varchar(100), user_name varchar(100), srch_name varchar(100));

insert into tst_srch values (1,'USER1','SRCHA');
insert into tst_srch values (2,'USER1','SRCHB');
insert into tst_srch values (3,'USER1','SRCHC');
insert into tst_srch values (4,'USER1','SRCHD');
insert into tst_srch values (5,'USER2','SRCHC');
insert into tst_srch values (6,'USER2','SRCHD');
insert into tst_srch values (7,'USER2','SRCHD_1');

Could I write a procedure like copy_searches('USER1','USER2') that would copy all USER1's searches to USER2 - including renaming any duplicates.

So it would create these new rows:

8,USER2,SRCHA
9,USER2,SRCHB
10,USER2,SRCHC_1
11,USER2,SRCHD_2

I've looked at various insert statements, merge and match statements and exception handling in procedures .
