mysqliで2つのエラーが発生します。

警告：mysqli_stmt :: execute（）：（HY000 / 2014）：コマンドが同期していません。235240行目の/.../でこのコマンドを実行することはできません。

コマンドが同期していません。現在、このコマンドを実行できません。致命的なエラー：241行目の/.../で2つのレベルを中断/続行できません

以下のクエリと挿入の順序が原因でエラーが表示されることを知りたいです。

これは、適切なタイミングでステートメントを閉じているためです。

$insertanswer->close();適切な場所または別のクエリの前にステートメントを閉じます
