Oracle PL/SQL Language Pocket Reference, Second Edition

The 'Oracle PL/SQL Language Pocket Reference' is a good pocket reference for Oracle 11g but I feel that this subject matter is tough to condense in size. I feel that this isn't a niche book that really accomplishes much. I'll still give it 4 stars because it's handy but I think you would be more apt to pick up one of the bigger Oracle PL/SQL books by O'Reilly instead.****
