What is the name of this anti-pattern?

Of course, some of you figured this out. This usually happens when programmers get too much OO and forget about performance and have a database.

As an example, let's say that we have an email table and they must be sent by this program. At startup, it searches for everything that needs to be sent as follows:

Emails = find_every_damn_email_in_the_database();
FOR Email in Emails
  IF !Email.IsSent() THEN Email.Send()

This is good in terms of do-not-repeat-yourself, but sometimes it is inevitable, and it should be:

Emails = find_unsent_emails();
FOR Email in Emails
  Email.Send()

Is there a name for this?

Partially inspired by the 1800's “lazy filter (anti) pattern”, how about “dysfunctional programming” (ie the opposite of functional programming)?
