Title: Average standard
Review: I feel the book should contain the working examples. some of examples in this book challenges the reader's debugging power. For the first time reader this kind of interaction is not welcome. for eg; in the page 818 , eg. relating to LOB variables, the sql is not working. particularly for the clob declaration . the error says "default character set is of varying width". Please give the intial reader with some working examples.
