Balaraju,
When the line
set pack=''
is removed in favour of
declare pack text default '';
MySQL 5.0.37 accepts the procedure. That looks like a MySQL bug. Will
you report it, or shall I?
When the sproc runs, the first NULL passed to CONCAT() sets pack to
NULL. CONCAT_WS() ignores NULLs. That gives us...
drop procedure if exists activity1;
delimiter |
create procedure activity1()
begin
declare done int default 0;
declare pack text default '';
declare name, logout, login varchar(50);
declare cur1 cursor for
select
user_name,
concat(logindate, ' ', logintime),
concat(logoutdate, ' ',logouttime)
from playersloginfo;
declare continue handler for sqlstate '02000' set done = 1;
open cur1;
repeat
begin
fetch cur1 into name, login, logout;
set pack = concat_ws(pack, name, ',', login, ',', logout,';');
end;
until done end repeat;
close cur1;
select pack;
end;
|
delimiter ;
