Question

Hi, I’m working on a java project where I have to retrieve the last customer added id i.e Max(c_id). But in my database c_id is in text (varchar) format, so how do I retrieve the max?

    Connection conn;
    Statement st;
    Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
    conn=DriverManager.getConnection("jdbc:odbc:rrr");
    st=conn.createStatement();

 String query[] ={"SELECT Max(cid) FROM client"};
  for(String q : query){
     ResultSet rs = st.executeQuery(q);        
     while (rs.next()) {
        String name = rs.getString("cid");
        Text1.setText(name);

Answer 1

Check with the following:

select * from client order by cid desc limit 1,1;
