Since you have specified no WHERE clause in your query, MySQL will return
a result set with one row per row in your table.  The value of last_insert_id()
will be 0 if you have not inserted a record into a table with an AUTO_INCREMENT
column at some point in the same server session.

What exactly are you trying to do?
