Re: tables with no synonyms

Another type of improvement would be to have the query build your CREATE
PUBLIC SYNONYM statements for you instead of just selecting the names of the
objects... something like this (this is a quick answer so please forgive any
typos or minor syntax errors...):

SELECT 'CREATE PUBLIC SYNONYM ' || a.object_name || ' FOR ' || a.owner ||
'.' || a.object_name || ';'
FROM...

Then you could look over the results, mouse-copy them, and be done.

 Along with the several good answers to this thread, I'll point out a
couple of "gotchas":
The subject of the e-mail says "tables" but the original query was linking
to DBA objects.
The first question is: you are looking for missing synonyms for which
object types? Synonyms for views, tables, sequences, procedures, functions,
packages, materialized views?
Second question is: are the synonyms supposed to have the same names as
the objects they are pointing to?

See the comment lines in this query:

column object_name format a30
select
   a.owner, a.object_name, a.object_type
 from
   dba_objects a
 where
   a.owner = '&BASE_OBJECT_SCHEMA'
   -- choose the appropriate object types for the "base object"
   and a.object_type in
      ('FUNCTION', 'MATERIALIZED VIEW', 'PACKAGE', 'PROCEDURE',
       'SEQUENCE', 'TABLE', 'VIEW')
   and not exists
     (select null from dba_synonyms b
       where
         b.owner = '&SYNONYM_SCHEMA'
         and a.owner = b.table_owner
         and a.object_name = b.table_name
         -- include this line if the synonym must have the same name as
the
         -- "base object"
         and b.table_name = b.synonym_name
     )
 order by a.owner, a.object_type, a.object_name ;

Assuming I've understood the question correctly, you can just take the
objects (including program units) that are owned by user A, and subtract
(MINUS) the synonyms owned by B that reference those objects in A.

select object_name, owner from dba_objects where owner = 'A'
minus
select table_name,table_owner from dba_synonyms where owner = 'B'
/
