Hi I want to "barge" in on this question, as it has bothered me in the past as well. The reason being: I did the last write to the table maybe a day ago, but I want to write a script that can give me some "stats" on the table at any time, so it also makes sense to me to be able to have a get_last_entry() function, or a total_rows_in table() (well, I guess you can do that with a select * from table), but I think where the problem comes in with last_insert_id(), is that you actually have to insert something into the table to get the last id, and I don't always want to insert something in the table? Is there a way to do that?
