Java ODBC

public class hw3_2 {

    public static void main(String args[])
    {
       
        //Variables for database insert set by JOptionpane data input
        String course = JOptionPane.showInputDialog(null, "Course ID:");
        String desc = JOptionPane.showInputDialog(null, "Description:");
        String cred = JOptionPane.showInputDialog(null, "Credits:");
        int credits = Integer.parseInt(cred);     
       
        //DB Connection
        String url = "jdbc:odbc:registrar";
        Connection con;
        Statement stat;
       
        String insert;
        insert = "INSERT INTO courses VALUES ('" + course + "','" + desc + "','" + credits + "');";
       
        try
        {
            Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
        }
        catch(java.lang.ClassNotFoundException e)
        {
            System.err.print("ClassNotFoundException: ");
            System.err.println(e.getMessage());
        }
       
        try
        {
            con = DriverManager.getConnection(url, "", "");
            stat = con.createStatement();
            ResultSet rs = stat.executeQuery(insert);
            
            System.out.println("Data successfully added to Courses table.");
           
            stat.close();
            con.close();
        }
           
        catch (SQLException ex)
        {
            System.err.println("SQLException: " + ex.getMessage());
        }
    }
}

The insert query works as intended, however I'm getting "SQLException: General error" from the 2nd catch - what error is it catching?

More baseless assumptions on your part. Your mistake here is that you assume that anyone who desires the help of others needs to have everything spelled out for them. Somehow you believe that by not learning myself, that I expect you to simply hand me the answer, no questions asked. You should be careful about making such uninformed assumptions; your ignorance is showing.
