Database object security

Question

Hi all,
Am trying to work on a table in my database which was created by user "xyz". this however implies that the table would exist in the schema belonging to user"xyz".
From the SQLPLUS> prompt, I can not use any DML or DDL syntax on the objects created by this user "xyz". Not even a "desc table_name" would give the desired result. however it gives an error: "object does not exist".
If you log into the enterprise manager as user "sys", you can view the description of the tables belonging to the user"xyz" but you can not have access to the content of the tables belong to the user"xyz".
How do I veiw the content of the tables belonging to user"xyz" and how do i sent such security on database objects I wish to have that characteristic.
Thank you in advance.

Hi,
Please take a look at example below :
--- USER : "DB_USER01"
SQL> create table xyz(id number(5));
Tabela criada.
SQL> insert into xyz values(1);
1 linha criada.
SQL> insert into xyz values(2);
1 linha criada.
SQL> select * from xyz;
ID
1
2
SQL>
--- USER : "DB_USER02" - (other sqlplus session).
SQL> select * from db_user01.xyz;
select * from db_user01.xyz
ERRO na linha 1:
ORA-00942: a tabela ou view não existe
--- Back to USER : "DB_USER01" and grant SELECT ANY TABLE TO db_user02;
SQL> GRANT SELECT ANY TABLE TO "DB_USER02";
Concessão bem-sucedida.
--- back to USER : "DB_USER02" to try the select statement again;
SQL> select * from db_user01.xyz;
ID
1
2
SQL>
I hope this can help you a little.
