Say you have:

  <input type="checkbox" name="query" value="1"> User1 His house
  <input type="checkbox" name="query" value="2"> User2 Her house

Then you can do:

    String sids = "" ;
    String select = "SELECT * FROM USERTABLE WHERE
    String[] ids = request.getParameters( "query" ) ;
    for( int i = 0 ; i < ( ids == null ? 0 : ids.length ) ; i++ )
        if( i > 0 )
            sids += " OR " ;
        sids += "( ID = " + ids[ i ] + " ) " ;
    if( sids.length() > 0 )
         out.println( "EXECUTE QUERY " + select + sids ) ;
