Daft newbie question: active_record vs standard mysql query

[eluser]mi6crazyheart[/eluser]
I exactly can't say whether using active record generate some delay in query executing(may be yes little bit) but using active record is really kill u'r lot of tensions which u could probably get if u make plain sql query to mysql. Like.. it has make query safe from sql injection, u can use multiple RDBMS easily, easy to memories, Error tracking much more easy etc.

In fact, such things(ORM, Active record pattern) really popular when it needed to work with different kind of DB.
