Hi,

Let us assume a table with 2 coloumns name and slno

name varchar(20)
slno varchar(5)

and go thru this code,i think your problem will get solved.

------------------------------------***--------------------------
import java.sql.*;
import java.util.*;
public class Test{
String name=null;
String slno=null;
public static void main (String a[])throws Exception{
Connection conn=null;
try{
Class.forName("oracle.jdbc.driver.OracleDriver");
conn = DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:xe","system","root");
System.out.println ("Database Connected.");
String sql="select * from test ";
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery(sql);
if(!(rs.next())){
Collection colc = new ArrayList();
colc.add("null");
System.out.println(colc);
}
else{
stmt.executeUpdate("INSERT INTO test " + "VALUES ('siva','649')");
System.out.println ("query");
}


}
catch (Exception exc){
System.out.println(exc + "<br>");
}
conn.close();
System.out.println ("Database closed.");
}
}
----------------------------------***---------------------------------
<H3>To check weather there are any contents in the ResultSet
this is done at</H3> if(!(rs.next()))

Thank u
All the best!!
