如何使用FluentPDO检测错误

Question

I am using FluentPDO to build my queries.

When I execute an insert statement, it returns False if it is unable to do so. However, I am unable to figure out how to retrieve the error behind the failure.

Does anyone know how to handle errors while using this library?

This is my current code...

function doInsert() {
    $pdo = new PDO("mysql:dbname=blog", "root", "password");
    $fpdo = new FluentPDO($pdo);

    $values = [
        'field1' => 'value 1',
        'field2' => 'value 2',
        'field3' => 'value 3',
    ];

    $query = $fpdo->insertInto('my_table', $values)->execute();
    if (!$query) {
        // what to type here to determine error
    }
}

This is NOT the answer, but the explanation from author (FluentPDO/BaseQuery.php Line: 98):

    // At this point, $result is a PDOStatement instance, or false.
    // PDO::prepare() does not reliably return errors. Some database drivers
    // do not support prepared statements, and PHP emulates them.  Postgres
    // does support prepared statements, but PHP does not call Postgres's
    // prepare function until we call PDOStatement::execute() (below).
    // If PDO::prepare() worked properly, this is where we would check
    // for prepare errors, such as invalid SQL.
