Retrieve id of each INSERT statement in multi query

Question

Is it possible to retrieve id (ua_id is in my case) for each INSERT statement in following SQL request

INSERT INTO users_addresses (ua_user_id, ua_address_id         


        

Answer 1

Yes. Use $mysqli->insert_id - see working example below.

$mysqli = new mysqli(host, user, pass, db);

$query  = "INSERT INTO users_addresses (ua_user_id, ua_address_id) VALUES (1,1); ";
$query .= "INSERT INTO users_addresses (ua_user_id, ua_address_id) VALUES (1,2); ";
$query .= "INSERT INTO users_addresses (ua_user_id, ua_address_id) VALUES (1,3); ";

if ($mysqli->multi_query($query)) {
    do {
        /* Returns the auto generated id used in the last query */
        printf("%d\n", $mysqli->insert_id);
        /* Check if loop should continue */
        if ($mysqli->more_results() === FALSE) break;
    } while ($mysqli->next_result());
}

Use built in mysqli::$insert_id - documentation: http://php.net/manual/en/mysqli.insert-id.php
