Using Reg Ex in a mySQL update statement

Question

I'm trying to change a number of domain names in email addresses in a mySQL table such as

name@old.domain.co.uk to something like name@newdomain.com

Can I use a Regular Expression to do this in an update statement and if so how would I go about this?

Answer 1

There's no regex replace in MySQL but you can use an UDF (User defined function) like these:

No, sorry MySQL regex functionality is limited to just searching, you can't directly replace with it.

Using a UDF to give regex functionality works though, if you want to go that route -
