Multiple insert locking question

do you need to lock table to ensure concurrent inserts

[proper_bo]

I am doing a MySQL insert that involves putting 4 new lines into a table.

My questions is simple.

To ensure the lines get concurrent id's (eg. 123,124,125,126) do I need to lock the table during insert or will this happen as standard?

Thank you.

It should happen automatically, I believe. You shouldn't need to lock it.
