    Default SQL Query

    I have Paradox database
    for connecting to db i use this class

    package sqlClasses;
     
    import java.sql.*;
     
    public class Paradox {
     
        public static Connection createConnection() {
            try {
                Class.forName("sun.jdbc.odbc.JdbcOdbcDriver").newInstance();
                Connection conn = DriverManager.getConnection("jdbc:odbc:Odds-Database", "user", "pass");
                return conn;
            } catch (Exception e) {
                System.out.println(e);
                System.exit(0);
                return null;
            }
        }
    }

    i want to fill table with data from database, and i use this method:

    public void roundTable() {
            TableModles tm = new TableModles();
            tm.roundTable();
            try {
                Connection con = Paradox.createConnection();
                Statement s = con.createStatement();
                s.executeQuery("SELECT Kolo, Od_datuma, Do_datuma FROM Kola");
                ResultSet rset = s.getResultSet();
                if (rset != null) {
                    tables.CreateTables.roundTable((DefaultTableModel) oddsmaker.OddsMakerView.roundTable.getModel(), rset);
                    con.close();
                }
            } catch (Exception e) {
                System.out.println(e);
            }
        }

    Its working fine but in the table where I put the columns "Od_datuma" and "Do_datuma" i need to fill table only with date , but with this code is filled with date and time.
    Db column is type DATE, how to edit the query to get only the DATE from db?

    in your executeQuery method you're selecting 3 columns from the table when u only need 1... change the statement to select whichever column holds the date information (im guessing "Od_datuma") and it should work

    a) Do this on the database side - I am not familiar with Paradox, but many databases have ways of converting one date data type to another (for instance, in MySQL you can use the DATE function). b) Do this after you pull the timestamp, use the Date object to format this however you wish.

    I have read on microsoft site that Paradox Data type can't be converted with operation cast or convert, so im looking for another solution

    Then use option b. Perform the query, use the getDate function of ResultSet(presuming the driver supports this operation), and use the returned Date object as needed.

    Default Re: SQL Query

    Sorry, I don't know what TableModles is, nor exactly where you are stuck. I recommend breaking the problem down as small as possible, being explicit about the problem, post an SSCCE, and ask a specific question regarding your code.

    I feel like we are going in circles. Don't expect anyone to have any clue what you are talking about unless you provide all the details, better yet post code that is succinct and which clearly demonstrates what you are talking about (in other words, an SSCCE). I recommend reading what an SSCCE is, and reading the link in my signature entitled 'Getting Help'. There's not much more help I can provide at the moment.
