As stated in the manual:

LAST_INSERT_ID() (with no argument) returns a BIGINT (64-bit) value representing the first automatically generated value that was set for an AUTO_INCREMENT column by the most recently executed INSERT statement to affect such a column. For example, after inserting a row that generates an AUTO_INCREMENT value, you can get the value like this:

mysql> SELECT LAST_INSERT_ID();
        -> 195
