Database cache problem

  • Hi,
    Found one issue with the database cache. Sample:

    $wpdb->query("TRUNCATE TABLE xyz");
$wpdb->get_var("SELECT * FROM xyz WHERE fieldId = 1"); // return 0 --> correct
$wpdb->insert("xyz", ['fieldId' => 1]); // insert record
$wpdb->get_var("SELECT * FROM xyz WHERE fieldId = 1"); // return 0 --> wrong!

    Result stays cached even after insert/update.
