Hi Master,

How do I pass a table column value into string variable. See my code below:

import java.sql.*;
public class Waheed {
    public Waheed() {
    }
     public static void main (String args [])
  {
   String s = "9 23 45.4 56.7";

      System.out.println ("going for connection");
       // DriverManager.registerDriver (new oracle.jdbc.driver.OracleDriver());
        
      try{ 
      Class.forName("oracle.jdbc.driver.OracleDriver");
       Connection conn = 

DriverManager.getConnection("jdbc:oracle:thin:@fahim:1521:aamir","muhammad","mfa786");
        Statement stmt = conn.createStatement();
        ResultSet rset = stmt.executeQuery("select accid from accbal");
         System.out.println ("going for connection");
        while (rset.next())

            s= rset.getString("accid");  this line give me error

            System.out.println (rset.getString("accid"));
         System.out.println (s);
      }
      catch(Exception e){
          e.printStackTrace();
      }
  }
}



This line give me an error:

s= rset.getString("accid");
s is string variable

Plese give me an idea how I can pass accid in s variable.

Thanks.

Aamir

You have missed putting braces around the while-loop block, so only the statement
s= rset.getString("accid");
is executed in the loop. The print statements gets executed after the result set is exhausted - therefore the error.

Place the print statements (and any other processing you want to do with the result set) within the while-loop - it'll work fine!
