Syntax error with Complex MySQL Procedure/Function - mysql

Question

I have come up with a fairly complex query that computes and returns two date fields based on some input arguments. These date values need to be further used in a report which will have lots of other fields. As you can see there are 4 input variables and 2 output variables.
set #caSplit = 0.3;
set #flSplit = 0.7;
set #formulaForAvgUsed='useAvgOfAll';
set #itemNumber = 'TAB_120_IVR_POLY';
select
max(case when compCA >0 then rollingDate else current_date end) as oosDateForCA,
max(case when compFL >0 then rollingDate else current_date END) as oosDateForFL
from
(
select
items.item, items.rollingDate, perDaySalesCA, perDaySalesFL,
items.total_items_in_ca, total_items_in_fl, flAsnItems.flASNQty, caAsnItems.caASNQty,
#prevDayCA := case
when cntr = 0 then total_items_in_ca
when greatest(#prevDayCA,0) + coalesce(caASNQty,0) = 0 then 0
else greatest(#prevDayCA,0) - perDaySalesCA - IF(#prevDayFL > perDaySalesFL, 0, perDaySalesFL) + coalesce(caASNQty,0)
end as compCA,
#prevDayCA as caInv,
#prevDayFL := case
when cntr = 0 then total_items_in_fl
when greatest(#prevDayFL,0) + coalesce(flASNQty,0) = 0 then 0
else greatest(#prevDayFL,0) - perDaySalesFL - IF(#prevDayCA > perDaySalesCA, 0, perDaySalesCA) + coalesce(flAsnQty, 0)
end as compFL,
#prevDayFL as flInv

My intent is to create a procedure and select the values in the top level into the output variables. Using MySQL Workbench when I try to create with this syntax, it throws a syntax error but doesn't say what exactly is the issue.

Can anyone help ?

Answer 1

I figured out , the syntax to load into multiple variables is
select 'abc', 'def' into var1, var2
Earlier I was using
select 'abc' into var1, 'def' into var2
