Does a MySQL multi-row insert grab sequential autoincrement IDs?

Question

I think this is true, but I haven\'t found anything on the web to confirm it. I can get the first id generated for the autoincrement field using last_insert_id(), but can I

Answer 1

A multi-row insert is just a bulk-operation that performs the same operation over and over again. When an insert statement is fired, it fires a trigger that generates the ID.

So if the database engine used, performs all of its work in a sequential way (queue like - first-in first-out) then yes, sequential id's will be one increment higher than the previous id; if the data is inserted in a multi-threaded way where statements are fired in parallel, then no, id's will be given at "random".

I am not aware of any mysql engine that guarantees this, but then again I haven't made much research in this specific subject.
