how can check there record , value database using single resultset in java...

i'm using code check there record in database or not..

then i'm record set values it's not fetch second row values... display 1 row values... give me solution....

try {     class.forname("sun.jdbc.odbc.jdbcodbcdriver");     connection conn = drivermanager.getconnection("jdbc:odbc:mobile","","");     string qry = "select * login";     resultset rs = stmt.executequery(qry);      if (rs.next()) {         while(rs.next()) {              system.out.println(rs.getstring("value1");             system.out.println(rs.getstring("value2");         }          } else {         system.out.println("no records");     } } catch(exception e) {       system.out.println(e); }

try this:

if want trigger whether there records exist in database or not:

if (!rs.next())  {     system.out.println("no records found"); } else {     while(rs.next())     {          system.out.println(rs.getstring("value1");         system.out.println(rs.getstring("value2");     } }

if don't want trigger whether there records exist in database or not following enough:

while(rs.next()) {      system.out.println(rs.getstring("value1");     system.out.println(rs.getstring("value2"); }

update1 try this: 

try {     pstmt = con.preparestatement("select * login", resultset.type_scroll_insensitive,resultset.concur_updatable);     rs = pstmt.executequery();     if (!rs.next())      {         system.out.println("no records found");     }     else     {         rs.beforefirst();         while(rs.next())         {              system.out.println(rs.getstring("value1");             system.out.println(rs.getstring("value2");         }     } }
