If your action of sending email to the users is not very often, you can select email from comment into a tmp table, then make the users data table joining the temp one, and this should be more efficacious.

Very basic. Looping over 2 tables - an email table, and a data-table. I'm using * just for ease for the time being: SELECT * FROM f_c_users,f_comments WHERE fcEmail=cemail GROUP by fcEmail If there are more than one records in the data table *per* email, then I want to group them into one email per user. Instead of sending 10/20/100 emails per person for each record in the data-table. So I just want to collate everyone's data into one email. Any thoughts welcome!
