I'm fairly new to Oracle database. I have installed Oracle Database 11g R2
on Oracle Linux 6
. I have successfully created a new database with dbca
and connected to the database using:
$ sqlplus "/ as sysdba"
I successfully created a table and inserted some data and performed some selects:
SQL> CREATE TABLE Instructors (
tid NUMBER(7) PRIMARY KEY,
fname VARCHAR2(32),
lname VARCHAR2(32),
tel NUMBER(16),
adrs VARCHAR2(128) );
Table created.
SQL> INSERT INTO Instructors (tid, fname, lname, tel, adrs)
VALUES (8431001, 'John', 'Smith', 654321, 'London');
1 row created.
SQL> SELECT count(*) FROM Instructors;
COUNT(*)
----------
1
Then I created a new user with the CONNECT privilege:
SQL> CREATE USER teacher1 IDENTIFIED BY pass1;
User created.
SQL> GRANT CONNECT TO teacher1;
Grant succeeded.
Then I created a new role with appropriate object privileges:
SQL> CREATE ROLE instructor;
Role created.
SQL> GRANT SELECT, UPDATE ON Instructors TO instructor;
Grant succeeded.
And granted the role to the user:
SQL> GRANT instructor TO teacher1;
Grant succeeded.
Next I exited sqlplus with exit;
and connected as the new user to test it. I logged in successfully to the database with:
$ sqlplus teacher1

But when I try to select from the table it says:
SQL> SELECT * FROM Instructors;
SELECT * FROM Instructors
*
ERROR at line 1:
ORA-00942: table or view does not exist
What I'm missing here ?!
