Hi!
I have a database where several users can connect and input data.
I managed to have my insert queries as atomic, but I was wondering about one special case: I make one insert, and retrieve the last id inserted by mysql because I need to update an other table with that id.
- if one user inserts and retrieves the id, but between both one other has inserted something the id returned will be the right one?
Last_insert_id() is consistent on a per-connection basis, meaning you don't need to use lock (hopefullly !)

btw, what do you mean by : "I managed to have my insert queries as atomic". Because if you do : INSERT .... it's already suppose to be atomic.
