Grant Select on all tables in a schema

We can use a PL/SQL and write a simple loop statement to automatically execute the GRANT SELECT.

Example:

BEGIN
   FOR R IN (SELECT owner, table_name FROM all_tables WHERE owner='FINANCE') LOOP
      EXECUTE IMMEDIATE 'grant select on '||R.owner||'.'||R.table_name||' to MEREBA';
   END LOOP;
END;
/
 where 'FINANCE'  is the owner schema and 'MEREBA'  is the grantee.
