How to make a request and immediately display it on the screen?

Question

MySQL

I make a request connection.query("INSERT INTO ... It creates a new line, how can I immediately pick up a column from this line?
At the time of creation, one of the columns is automatically affixed (id), I immediately display this id after creation.
You can, of course, do immediately another request that will take the last added BUT, it is not clear how this will behave if 2 people simultaneously create

Answer 1

When using INSERT, and set to autoincrement, you can get the id of the newly added column like this: result.insertId

Answer 2

php mysql how to get id of added record
mysql_insert_id
