Question

I want to quickly update a table to get rid of any real data that got pulled down to a test server.

UPDATE users SET email = CONCAT ("fake", users.id, "@mycompany.org")

Is anything like that possible or will I need to write a script?

Answer 1

Yes, the query you are using will work. That is, for a row like:

id = 21
name = 'sth'
email = NULL

It’ll update and set the email to:

'[e-mail]'

And similarly for all the rows in the entire table.
