Question

I have the following code which inserts 1 row into the database:

public function fixed($fieldDay, $fieldNight) {

    $pdo = new SQL();
    $dbh = $pdo->connect(Database::$serverIP, Database::$serverPort, Database::$dbName, Database::$user, Database::$pass);

    $this->sql = "INSERT INTO tblfixedfare (SELECT NULL, MAX(FixedFareID)+1, '1', '$fieldDay' FROM tblfixedfare)";

try {
        // Query
        $stmt = $dbh->prepare($this->sql);

        $stmt->execute();

        $count = $stmt->rowCount();

        echo $count.' row(s) inserted by SQL: '.$stmt->queryString;

        $stmt->closeCursor();

    }

    catch (PDOException $pe) {
        echo 'Error: ' .$pe->getMessage(). 'SQL: '.$stmt->queryString;
        die();
    }

    // Close connection
    $dbh = null;
}

}

At the same time this is being executed, I want to insert another row into the same table:

$this->sql = "INSERT INTO tblfixedfare (SELECT NULL, MAX(FixedFareID)+1, '2', '$fieldNight' FROM tblfixedfare)";

How would I go about doing this?

EDIT

Also, for both inserts the value for MAX(FixedFareID)+1 needs to be the same value.

Answer 1

Change the SQL query definition to this:

$this->sql = "
    INSERT INTO tblfixedfare 
        SELECT NULL, MAX(FixedFareID) + 1, '1', :fieldDay
        FROM tblfixedfare
        UNION
        SELECT NULL, MAX(FixedFareID) + 1, '2', :fieldNight
        FROM tblfixedfare
";

…and change the execute() call to this:

$stmt->execute(array(
    'fieldDay' => $fieldDay,
    'fieldNight' => $fieldNight
));
