These days I am looking for a web developer in Lithuania. It is not very easy because it’s a small country… but on Linkedin you can find quite many profiles.
The problem is, sometimes you can’t connect to these people because they are too far out of your network.
Usually you would get the first name of the person and some skills in his profile.

When building a web application it can seem a bit tricky to get the value of the id (primary key) of the latest row inserted in a mysql table.
It is not that complicated.
The function LAST_INSERT_ID() can help you finding that. This function will return the latest auto-incremented value. No need to specify the table, it just takes the latest one.
SELECT LAST_INSERT_ID() ;
The next question is: what happens when I have many concurrent sessions on the same server? Will I get the latest inserted id from another user?
