Grant Select on all Tables Owned By Specific User

Question

I need to grant select permission for all tables owned by a specific user to another user. Can I do this with a single command along the lines of:

Grant Select on OwningUser.* to ReceivingUser

Or do I have to generate the sql for each table with something along the lines of:

 Select 'GRANT SELECT ON OwningUser.'||Table_Name||'TO ReceivingUser' 
 From All_Tables Where Owner='OWNINGUSER'

Answer 1

Only via the second option AFAIK.

Answer 2

Well, it's not a single statement, but it's about as close as you can get with oracle:

BEGIN
   FOR R IN (SELECT owner, table_name FROM all_tables WHERE owner='TheOwner') LOOP
      EXECUTE IMMEDIATE 'grant select on '||R.owner||'.'||R.table_name||' to TheUser';
   END LOOP;
END;
