Jdbc database access

Question

The following is not running and it got compiled . I want to know whether it is possible to open a recordset
for processing based on a value from another recordset .
I need to get values from a recordset based on a value from previous recordset.. Nesting of loops is done for that purpose...
Please clarify in this issue..
The code is enclosed:
import java.sql.*;
import java.math.*;
import java.io.*;
import java.awt.*;
public class Test {
public static void main (String args []) throws Exception {
DriverManager.registerDriver (new sun.jdbc.odbc.JdbcOdbcDriver());
Connection conn = DriverManager.getConnection ("jdbc:odbc:eash","sa","sa");
Statement stmt = conn.createStatement ();
stmt.executeUpdate("use pubs");
ResultSet rset = stmt.executeQuery ("SELECT * FROM publishers");
while (rset.next ()){
System.out.println (rset.getString (1));
ResultSet rs = stmt.executeQuery ("SELECT title FROM titles where pub_id = " + rset.getString (1));
while(rs.next())
System.out.println (rs.getString (1));

Answer 1

hi,
the problem i think is in the fact that when u query that resultset twice, it seems to work the first time but not the second. you could do the following changes and give it a try.
System.out.println (rset.getString (1));
ResultSet rs = stmt.executeQuery ("SELECT title FROM titles where pub_id = " + rset.getString (1));to correct the problem, first store the result of rset.getString(1) into a String variable and then use that. for eg
String value = rset.getString(1);
System.out.println (value);
ResultSet rs = stmt.executeQuery ("SELECT title FROM titles where pub_id = " + value);hope that helpz
cheerz
