This book covers one of the most exciting features of Oralce 10G, i.e Regular Expressions. Till Oracle 10G, Oracle was supporting only LIKE predicate for pattern matching. This Book covers all 4 functions (REGEXP_INSTR, REGEXP_LIKE, REGEXP_REPLACE, REGEXP_SUBSTR) of Regular expression supported by Oracle. It is for both novice users who didn't use Regular expressions till now and for the users who used other languages like Perl, UNIX grep command etc.,

We can use this book as quick reference or regular expression tutorial also. It not only explains what oracle supports as far as Regular Expressions is concerned, it also covers the difference between Perl and Oracle.

Finally it covers a list of error messages you may encounter and explanation and how to resolve them. This book is almost like a complete reference for Regular expression (hope I should write this sentence after getting experience on Oracle 10G).
