Tell me why DBAs don’t like cursors?


I like to phrase this interview question this way because I’m not saying the DBA is right – I’m just asking the developer to explain the DBA’s point of view. I don’t have a problem with the developer rolling their eyes as they explain the answer, but I have a problem with the developer being surprised by the question.

The candidate gets bonus points if they seem even vaguely aware of the terms “set-based processing” and “row-based processing”, but that’s purely a bonus. (I wish I could say that these concepts are requirements, but in today’s economic market, companies don’t always want to pay top dollar to get the best candidates.)
