Yes. It is also possible for it the two to have different execution plans depending on the actual values of the literals. There is more to it than that, bind variable peeking, etc. but I don't know all the details beyond that.

Subject: Sanity check

Is there any reason why an INSERT using binds and the same INSERT using literals should differ in performance of the execution phase? (I'm aware of the difference with respect to parse phase.)
