从 C# 连接到 ms 访问时出现语法错误

Question

I am able to read from a MS Access database so I know I have set up my connection string correctly, but I keep getting "syntax error" when I try to insert into that MS Access database. I tried running the same query in Access directly and it works with no errors. Your help will be much appreciated.

public void connect()
{
    conn = new OleDbConnection(conn_string);
    conn.Open();
}

public void closeConnection()
{
    conn.Close();
}  

{
    connect();

    // submitQuery = "INSERT INTO TaskSchedular(Grade, Month, Day, Subject, DueDate, AssignmentLink, OrigScore, FinalScore, Task, Priority)  VALUES('8', '17', '10', 'test', '12', 'test', '12', '34', 'test', '2');";

    OleDbCommand cmdInsert = new OleDbCommand();
    cmdInsert.Connection = conn;
    cmdInsert.CommandText = "INSERT INTO TaskSchedular(Grade, Month, Day, Subject, DueDate, AssignmentLink, OrigScore, FinalScore, Task, Priority)  VALUES('8', '17', '10', 'test', '12', 'test', '12', '34', 'test', '2');";

    cmdInsert.ExecuteNonQuery();
                
    closeConnection();
}
catch (Exception ex)
{
    error_msg = ex.Message;
    //MessageBox.Show(error_msg);
}

Answer 1

Day and Month are reserved words in Access, so they need to be enclosed in square brackets. So this part

INSERT INTO TaskSchedular(Grade, Month, Day, Subject

should be:

INSERT INTO TaskSchedular(Grade, [Month], [Day], Subject

(There are potentially other issues here, such as specifying numeric values in quotes which probably shouldn't be in quotes, and ideally using parameters instead of putting the values directly in the SQL, but that's slightly separate from this direct question.)
