Support for regular expressions in SQL and PL/SQL is one of the most
exciting features of Oracle Database 10G. Oracle has long supported the
ANSI-standard LIKE predicate for rudimentary pattern matching, but
regular expressions take pattern matching to a new level. They provide a
powerful way to select data that matches a pattern, as well as to
manipulate, rearrange, and change that data.This concise pocket guide is
part tutorial and part quick-reference. It's suitable for those who have
never used regular expressions before, as well as those who have
experience with Perl and other languages supporting regular expressions.
The book describes Oracle Database 10G's support for regular
expressions, including globalization support and differences between
Perl's syntax and the POSIX syntax supported by Oracle 10G. It also
provides a comprehensive reference, including examples, to all supported
regular expression operators, functions, and error messages.O'Reilly's

expressions for the first time or applying your skills from other

Expressions Pocket Reference is the book to have close by.
