Anyone know about Parsing an email?

Hello everyone

Heres what it looks like:

I have a large file of over 40k email records. The emails are all mixed up and come in various formats but i noticed that most of them are in this format:

firstname.lastname@.email.com
firstname.middlename.lastname@.email.com

For all those emails with the period (.) in between, the (.) actually separates an individuals first and last name.

My task is this, to separate all the emails that are in this format into first and last name fields. I'm stimped folks and I'll really appreciate any pointers or ideas on how to go about solving this task.

Thanksuse substring and charindexsql
