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?

gently pointed me in the right direction without spelling it out for me
But you wanted the answer spelled out for you. Otherwise you would have found it yourself. Why are you so angry?
