Good day Oracle Experts:

I have a Schema called SAPDEV which has about 2000 tables in it.

I would like to create a new user called GMASTERS  that has SELECT only on all the SAPDEV schema with connect privliges only.  Can you give me a good example on how I would do this?

Thank you for your time today

I would create a role say readonly.

Grant select on the tables to readonly, then grant that role to gmasters.

I would also suggest creating synonyms so gmasters doesn't need to fully qualify the tables.

create role READ_SAPDEV_ROLE;

create user GMASTERS identified by pa55w0rd;

grant connect to READ_SAPDEV_ROLE;

DECLARE
    v_grantee VARCHAR2(30) := 'READ_SAPDEV_ROLE';
    v_owner   VARCHAR2(30) := 'SAPDEV';
BEGIN
    FOR x
    IN (SELECT    'grant select on "'              
               || owner
               || '"."'
               || object_name
               || '" to '
               || v_grantee
                   grant_sql
          FROM dba_objects
         WHERE owner = v_owner
           AND object_type IN ('TABLE', 'VIEW'))   -- remove VIEW if you want tables only
    LOOP
        EXECUTE IMMEDIATE x.grant_sql;
    END LOOP;
END;


grant READ_SAPDEV_ROLE to GMASTERS;

Just be aware with these approaches that if a new table is added to the SAPDEV schema privileges need to be granted on the new table to the user or role.
