cursor syntax in Mysql - mysql

Question

I followed the example here to a T. But I'm getting syntax errors all over the place. Aside from the fact my code sucks, where is the syntax error?
set #deviation = 30;
set #average = 200000;
DECLARE cur1 CURSOR FOR SELECT distinct subindustry FROM referraldb.report_referral_db_viz_qa;
DECLARE CONTINUE HANDLER FOR NOT FOUND SET done = 1;
open cur1;
read_loop: LOOP
fetch cur1 into sub;
if done then
leave read_loop;
end if;
select #d := max(date) from referraldb.report_referral_db_viz_qa;
select a.subindustry, a.report_time_id, a.dimension_id, a.brand_id, a.referral_source, a.date, a.pre, a.current_test, a.create_dt
from
(select distinct cur.subindustry, cur.report_time_id, cur.dimension_id, cur.brand_id, cur.referral_source, cur.date, cur.pre, cur.current_test, cur.create_dt
from
referraldb.report_referral_db_viz_qa cur
inner join referraldb.report_referral_db_viz_qa prv
on cur.report_time_id = prv.report_time_id
and cur.dimension_id = prv.dimension_id
and cur.brand_id = prv.brand_id
and cur.referral_source = prv.referral_source
and cur.date = date_add(LAST_DAY(DATE_SUB(#d, INTERVAL 1 month)), interval 1 day)
and prv.date = date_add(LAST_DAY(DATE_SUB(#d, INTERVAL 2 month)), interval 1 day)
inner join referraldb.dim_all_dimensions dims
on dims.dimension_id = prv.dimension_id
inner join referraldb.dim_brand brand
on brand.brand_id = prv.brand_id
where
dims.lag = 'immediate'
and dims.measure_type = 'visits'
and prv.subindustry = sub
and prv.report_time_id = 1
and abs((((cur.current_test - prv.current_test)/cur.current_test) * 100)) >= #deviation) a
inner join
(select distinct fact.subindustry, fact.report_time_id, fact.dimension_id, fact.brand_id, fact.referral_source, fact.date, fact.pre, fact.current_test, fact.create_dt
from
referraldb.report_referral_db_viz_qa fact inner join
referraldb.dim_brand brand

referraldb.dim_report_time t
on t.report_time_id = fact.report_time_id inner join

where dims.lag = 'Immediate' and dims.measure_type = 'Visits'
and fact.subindustry = sub
and fact.report_time_id = 1 and fact.date > DATE_SUB(#d, INTERVAL 13 month)
group by fact.referral_source, brand.Industry, fact.Subindustry, brand.Brand, dims.Activity, dims.Detail
having avg(current_test) > #average ) b
on a.subindustry = b.subindustry and a.report_time_id = b.report_time_id and a.dimension_id = b.dimension_id and a.brand_id = b.brand_id and a.referral_source= b.referral_source and a.date = b.date and a.pre = b.pre and a.current_test = b.current_test and a.create_dt = b.create_dt
end loop;
close cur1;

Answer 1

How do you execute this block? It should be inside a body of Stored procedure/function (or maybe a trigger). For example,
DELIMITER $$
CREATE PROCEDURE MyProc (//list of parameters)
BEGIN
// your code goes here
END $$
DELIMITER ;

Answer 2

You should add delimiter before and after procedure
DELIMITER $$
//procedure
DELIMITER ;
