Problem binding variable to query in procedure

Question

Hi folks,
I'm having an issue binding a variable to a query.  For example the following works in my procedure;
DECLARE V_PLANT NVARCHAR(4) := 'ACME';
tempVar = select field1 from myView where Plant = :V_PLANT;
When I debug my procedure I can see the variable V_PLANT = 'ACME' and tempVar contains 1 single value (field1) record.
Now, alternatively, if I try passing my variable like this it is not working (get error: no data found);
DECLARE V_PLANT NVARCHAR(4) := 'ACME';
ABCVariable NVARCHAR(45) := '';
select field1 into ABCVariable from myView where Plant = :V_PLANT;
However if I hard code the plant variable as a literal string like this I indeed get data;
DECLARE V_PLANT NVARCHAR(4) := 'ACME';
ABCVariable NVARCHAR(45) := '';
select field1 into newVariable from myView where Plant = 'ACME';
Result is I have a value of 'ACME' in ABCVariable.  It seems when I'm using SELECT INTO syntax I can no longer use variables in the where condition.
Any suggestions?
Thanks,

Hi Patrick
I cannot reproduce this problem:
create procedure get_article_by_label (IN v_article_label varchar)
language sqlscript
as
begin
    declare v_article_id integer := -1;
    select max(article_id) into v_article_id
    from efashion.article_lookup
    where UPPER(article_label) like '%' || UPPER(:v_article_label) || '%';
    select * from efashion.article_lookup
    where article_id = :v_article_id;
end;
call get_article_by_label ('Leather Belt');
ARTICLE_ID  ARTICLE_LABEL           CATEGORY            SALE_PRICE  FAMILY_NAME FAMILY_CODE
143848      Patchwork Leather Belt  Belts,bags,wallets  88.9        Accessories F60       
As you see I use the input variable in the WHERE condition, and reuse the found ID to select data again.
Not sure though, why it doesn't work in your case.
Is the target variable in your working example also ABCVariable or indeed newVariable?
