DELIMITER $$
create Procedure proc_answermigration()
begin
DECLARE #i,#n,#q,#ind,#pt varchar default '';
DECLARE #done,#aord int default 0;
DECLARE cur cursor for select ID, N, question, from test.qustionmigration;
DECLARE CONTINUE HANDLER FOR NOT FOUND SET #done = 1;
open cur;
read_loop: Loop
fetch cur into i,n,q;
IF done THEN
LEAVE read_loop;
END IF;
if n <> '' or n <> 'X'
then
select #ind = iq.question_id, #pt = iq.points from test.qustionmigration qm
inner join ilias.qpl_questions iq on qm.question = iq.question_text
where question = q
else
insert into qpl_a_sc
(
answer_id,
question_fi,
answertext,
points,
aorder,
tstamp
)
select (select sequence from qpl_a_sc_seq),
ind,
question,
pt,
aord,
'1342884200'
from test.qustionmigration
end if;
update qpl_a_sc_seq
set sequence = sequence + 1;
if #aord = 0 then set #aord = 1;
elseif #aord = 1 then set #aord = 2;
else set #aord = 0;
end loop;
CLOSE cur;
end$$
DELIMITER ;
i corrected some statements but still it has syntax error saying:
#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'LOOP; close cur; end' at line 52

Answer 1

Your last IF ELSE block is missing its END IF:
if #aord = 0 then set #aord = 1;
elseif #aord = 1 then set #aord = 2;
else set #aord = 0;
/* END IF either belongs here or after following statements, depending on your intended logic */
/* Either way, this block is unclosed when you close the loop */
end if
When the parser reads the END LOOP;, it is looking for the END IF, and reports a syntax error at LOOP.

Answer 2

You can't DECLARE user variables (those beginning with a #). Just SET them, or else use local variables (not beginning with a #).
