Granting select, insert to an user

Question

Hello,
i have a user, 'roger', with dba privileges. i created a view(named 'vw_absente'), and then a user, 'user1', to which i granted connect, resource, and then select, insert on vw_absente. but when i log off, and i log in with that user, i wanna select * from vw_absence, but i got that 'Table or view does not exist'.
However, i wanna in Forms, if that user logs on, when creating a new data block, to show only the tables and views the current user has privileges to. in my case i don't see any table or view when i log in with the 'user1' user.
What i did wrong?
so i wanna that user to update only some columns from a table (that's why i created the view and granted the select and insert privileges on that view, to 'user1' user).
Please help me
Thanks

The public synonym doesn't belong to your schema. You only see the objects which belongs to your schema. You didn't see the dual table in the selection as the public synonym doesn't belong to your schema. There's a public synonym for the dual table. The synonym belongs to the public schema. You can access the dual table via sys.dual or simply use the public synonym dual for sys.dual as there's a synonym which belongs to the public schma where your user belongs to...
just a test:
SQL> conn sys/oracle as sysdba
Connected.
SQL> create user testsyn identified by testsyn;
User created.
SQL> create table test (id number);
Table created.
SQL> grant all on test to public;
Grant succeeded.
SQL> create public synonym test for sys.test;
Synonym created.
SQL> grant connect, resource to testsyn;
Grant succeeded.
SQL> conn testsyn/testsyn
Connected.
SQL> select * from user_objects where object_name = 'TEST';
no rows selected
SQL> select * from test;
no rows selectedI can select on test altough in my schema there's no test object...
Also look at the dual table (user testsyn):
SQL> select * from dual;
D
X
SQL> select * from user_objects where object_name = 'DUAL';
no rows selected
SQL>  select * from all_synonyms where synonym_name = 'DUAL';
OWNER                      SYNONYM_NAME                TABLE_OWNER          TABLE_NAME               DB_LINK
PUBLIC                      DUAL                     SYS               DUALand the next:
SQL> conn sys/oracle as sysdba   
Connected.
SQL> insert into test(id) values (1);
1 row created.
SQL> insert into test(id) values (2);       
1 row created.
SQL> insert into test(id) values (3);
1 row created.
SQL> commit;
Commit complete.
SQL> select * from test;
     ID
      1
      2
      3
SQL> grant create table to testsyn;
Grant succeeded.
SQL> conn testsyn/testsyn
Connected.
SQL> select * from test;
     ID
      1
      2
      3
SQL> create table test (id number);
Table created.
SQL> select * from test;
no rows selectedThe first, I insert into the table, and as it is granted to the public schema the user testsyn can see te records in the test table where public test synonym points to. then, I created a test table in the testsyn schema, and as there is a more specific test table this one is used...
and one last sample:
SQL> conn sys/oracle as sysdba
Connected.
SQL> create user testsyn2 identified by testsyn2;
User created.
SQL> grant connect, resource to testsyn2;
Grant succeeded.
SQL> conn testsyn2/testsyn2
Connected.
SQL> select * from test;
     ID
      1
      2
      3
SQL> conn sys/oracle as sysdba
Connected.
SQL> create synonym testsyn2.test for testsyn.test;
Synonym created.
SQL> conn testsyn/testsyn
Connected.
SQL> grant select on test to testsyn2;
Grant succeeded.
SQL> conn testsyn2/testsyn2
Connected.
SQL> select * from test;
no rows selected
SQL> So, quick answer to your question: you only see objects in your own schema, that's why you didn't see your object although you created a public synonym ;).
