Question

I’m trying to create a table in my database through C# using the following method:

    private static void CreateTables()
    {
        _commandtext = "CREATE TABLE Users(" +
                        "ID Integer PRIMARY KEY, " +
                        "Username Text(20), " +
                        "Password Text(25), " +
                        "IBAN Text(18)" +
                        ");";
        _command = new OleDbCommand(_commandtext, _connection);

        _connection.Open();

        int number = _command.ExecuteNonQuery();  <<< Error

        _connection.Close();
    }

Somehow it returns an error: “Syntaxerror in fielddefinition”
What am I doing wrong?

Edit: Solved but nevertheless: I’m using this for Access

Have you tried adding square brackets around your names?

private static void CreateTables()
{
    _commandtext = "CREATE TABLE [Users](" +
                    "[ID] Integer PRIMARY KEY, " +
                    "[Username] Text(20), " +
                    "[Password] Text(25), " +
                    "[IBAN] Text(18)" +
                    ");";
    _command = new OleDbCommand(_commandtext, _connection);

    _connection.Open();

    int number = _command.ExecuteNonQuery();  <<< Error

    _connection.Close();
}

Maybe your DB thinks you’re referencing other fields instead of creating new ones with the names you put in.
