How to manipulate data over two tables in same database.

Question

hi, i am not a profficient java programmer, i was trying to copy filtered data from one table to another table.
i was trying to use
public static Connection getConnection() throws Exception {
     Driver d = (Driver)Class.forName
         ("sun.jdbc.odbc.JdbcOdbcDriver").newInstance();
     Connection c = DriverManager.getConnection
         ("jdbc:odbc:Driver={Microsoft Access Driver (*.mdb)};DBQ=stuff.mdb");
     return c;
and then
    theConn = myConnection.getConnection();
      ResultSet rs;
      Statement stmt;
      String sql;
      stmt = theConn.createStatement();
      sql =  "SELECT * FROM shisab, myhisab WHERE shisab.Who_Bought ='ron'";
           rs = stmt.executeQuery(sql);
           while (rs.next()) {
            System.out.println("date:"+rs.getString("shisab.Date"));                 
      rs.close();--------------------------------------
it does not show anything! in the output! i tried many things but i thing it is not supporting my multiple table syntax , i.e.: table1,table2 in teh from clause.
please help!
i just need to filter stuff from the shisab table and write the filtered data into
the myhisab table.

Your problem isn't in the Java code, it's your SQL code...
Your statement, as submitted, is an improperly formed multi-table select, where you never joined the second table. That won't work.
You need to look into the INSERT INTO statement. The exact syntax of your statement will depend on whether or not both tables contain the exact same column names, etc. A generic example based on what you have might look like:
INSERT INTO myhisab SELECT * FROM shisab WHERE Who_Bought = 'ron'HTH
