Having trouble doing multiple cursors in a MySQL stored procedure -


i'm writing store procedure create 2 temporary tables union select of two. when using either first or second cursor alone other commented procedure works, when run query create procedure 2 cursors, fails.i've changed code reflect ike walker's suggestion.

here script:

delimiter //  drop procedure if exists joinemailsmsdailygraph//  create procedure joinemailsmsdailygraph(in previousday varchar(20), in today varchar(20)) reads sql data  begin  declare hours int; declare sms int; declare email int; declare smsdone int default 0; declare emaildone int default 0;   declare cursorsms cursor select hour(sm.date_created) `hour of day`, count(*) smscount  sms_message_delivery smd  join sms_message sm on sm.sms_message_id = smd.sms_message_id date(sm.date_created) >= date(previousday) , date(sm.date_created) < date(today)  group hour(sm.date_created); declare continue handler not found set smsdone =1;   declare cursoremail cursor select hour(em.date_created) `hour of day`, count(*) emailcount  email_message_delivery emd left join email_message em on emd.email_message_id=em.email_message_id date(em.date_created) >= date(previousday) , date(em.date_created) < date(today)   group hour(em.date_created); declare continue handler not found set emaildone =1;  drop temporary table if exists tempsms; create temporary table tempsms (hours_day int, sms_count int, email_count int);  open cursorsms; sms_loop: loop  fetch cursorsms hours , sms;  if smsdone = 1  leave sms_loop; end if;  insert tempsms (hours_day, sms_count) values (hours, sms);  end loop sms_loop; close cursorsms;   drop temporary table if exists tempemail;  create temporary table tempemail (hours_day int , sms_count int , email_count int);  open cursoremail; email_loop: loop  fetch cursoremail hours, email;  if emaildone=1  leave email_loop; end if;  insert tempemail(hours_day, email_count) values(hours, email);  end loop email_loop; close cursoremail;   select hours_day, sms_count , email_count tempsms union select hours_day, sms_count, email_count tempemail;  end// delimiter; 

it gives error

query : create procedure joinemailsmsdailygraph(in previousday varchar(20), in today varchar(20)) reads sql data begin declare hours int...
error code : 1338
cursor declaration after handler declaration
execution time : 00:00:00:000
transfer time : 00:00:00:000
total time : 00:00:00:000

ive tried putting both continue handlers @ end of declare section complains declare block overlapping or so.

can please tell me i'm doing wrong? reading.

why using cursors ? without tmp table using union.

drop procedure if exists join_email_sms_daily_graph;  delimiter #  create procedure join_email_sms_daily_graph ( in previousday varchar(20),  in today varchar(20) ) begin  create temporary table tmp (  hours_day int unsigned,   sms_count int unsigned default 0,   email_count int unsigned default 0 )engine=memory;  insert tmp (hours_day, sms_count)  select  hour(sm.date_created) hours_day,   count(*) sms_count   sms_message_delivery smd  join sms_message sm on sm.sms_message_id = smd.sms_message_id  date(sm.date_created) >= date(previousday) , date(sm.date_created) <  date(today)  group  hour(sm.date_created);  insert tmp (hours_day, email_count)  select   hour(em.date_created) hours_day,   count(*) email_count   email_message_delivery emd left join email_message em on emd.email_message_id=em.email_message_id  date(em.date_created) >= date(previousday) , date(em.date_created) < date(today)   group  hour(em.date_created);  select * tmp;   drop temporary table if exists tmp;  end#  delimiter;
