Email address columns in SQL Server

user553 Published in June 23, 2018, 9:20 pm

What's the correct way to add a check constraint for columns that should only contain email addresses?

We've had buggy software in the past that's added garbage to email columns and I would like to prevent that from happening again.

Please note that "perfect" solutions are not expected. While full RFC compliance would be great, I think most of us can agree just catching obvious mistakes such as "domain/username" and "2017-12-3" would be enough.

And of course it cannot reject any valid email address.
