DROP PROCEDURE IF EXISTS getrolln;

DELIMITER //

CREATE PROCEDURE getrolln(in inrl varchar(30), in inrol int(10) )
begin
DECLARE done INT DEFAULT 0;
DECLARE xtroll int(10) default 2000;
DECLARE xformno int(10) default 0;
DECLARE a varchar(100) default 0;
DECLARE stroll int(10) default 0;
DECLARE xtable varchar(100) default 0;
set @xtable = inrl;

set @a=concat("select FORMNO from ", @xtable ," order by ATTEMPT,NAME,FNAME,MNAME");
DECLARE hs CURSOR FOR @a;

DECLARE CONTINUE HANDLER FOR SQLSTATE '02000' SET done = 1;



open hs;
repeat
FETCH hs into xformno;
set xtroll = xtroll + 1;
set @a=concat("update arl set ROLLNO = ",xtroll," where FORMNO = ",xformno);
PREPARE stmt FROM @a;
