statement stmt = sqlhelper.initializedb(); string query = "select status " +                  "from books " +                  "where bookid = '" + bookid + "'"; resultset rs = stmt.executequery(query); result = rs.getstring(1); rs.close(); sqlhelper.closeconnection();

a resultset object maintains cursor pointing current row of data. cursor positioned before first row...
