Description:
Many databases have a regexp replace function that you can use to do something like strip out bad characters. i,e, remove spaces, brackets, and dashes from a phone number.

It would be very handy is this was within MySQL so you can do translations during a Update or a Insert

Many mny thanks

Dave

How to repeat:

select regexp(client_ref,'[/W]') from orders

This would be a possible use

A workaround: https://github.com/hholzgra/mysql-udf-regexp/tree/master/regexp

Another workaround that doesn't depend on any extensions would be to use REPLACE() with individual characters:

But it's rather tedious and not suitable for non-trivial regular expressions.

Would be great if this simple but powerful feature was available in MySQL as well.
