It is a threaded query, so you've to mention the callback where it stores data of the query which was sent.

mysql_tquery(connectionHandle, "INSERT INTO...", "OnVehicleInsert", "i", entry); //You don't have to fill up entry if not needed.
forward OnVehicleInsert(entry_id);
public OnVehicleInsert(entry_id)
{
    printf("insert id : %d", cache_insert_id(connectionHandle));
    return 1;
}
