mysql and regular expressions

The first time I needed to have some kind of complex select statement, I started to pray about the ability to use regular expressions with mysql.

Easy as it may be: use REGEXP!

For example:

SELECT * FROM db.ip_addresses WHERE ip_address REGEXP '^192\.168\.0\.(133|135)$';

See the official documentation and details here.

Now save and quit... doh!

If you like me are annoyed by the "recording" feature on vim (or better, by the way you can accidentally start it), then you may find at least useful to learn how it can be actually used.

This post explains it.
