Session Summary for Attendees:  It has been possible to get regular expression support with its own set of functions since Oracle database release 10, but getting started with regular expressions is not easy. Most database developers would avoid them if at all possible.

With the current release of the Oracle database, regular expression syntax becomes more important. You can use it to redact data with DBMS_REDACT and to search for patterns using the Match_Recognize clause. This session covers the basic syntax and gives you an easy introduction to regular expressions with plenty of code samples.
