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

If you use LOCK TABLES, the batches should grab sequential id's.

Example:

LOCK TABLES users WRITE;

UNLOCK TABLES;

This will prevent multiple threads from writing to the table at the same time.
