You can use SQL command "select * from yourTable order by id desc limit 1", which returns the newest
record in table. It should works if your application doesn't have so many request for inserting new
line at one time.When your application will generate more lines between inserting and selecting new
ID, you should use transaction in mysql and lock table for inserting.
