SQLite データベースを使用して Web ページを作成しようとしています。テーブルがホストサーバーではなくローカルマシンに保存されていることを除いて、すべてが機能します。そのため、各ユーザーは自分が入力したデータしか見ることができず、まったく役に立ちません! SQLite をサーバーに向けるにはどうすればよいですか?
ここで変更が行われると思います。
var createStatement = "CREATE TABLE IF NOT EXISTS Contacts (id INTEGER PRIMARY KEY AUTOINCREMENT, firstName TEXT, lastName TEXT, phone TEXT)";
var selectAllStatement = "SELECT * FROM Contacts";
var insertStatement = "INSERT INTO Contacts (firstName, lastName, phone) VALUES (?, ?, ?)";
var updateStatement = "UPDATE Contacts SET firstName = ?, lastName = ?, phone = ? WHERE id = ?";
var deleteStatement = "DELETE FROM Contacts WHERE id=?";
var dropStatement = "DROP TABLE Contacts";
しかし、すべてのコードは以下のとおりです........
