SELECT INTO Variable in MySQL DECLARE causes syntax error?

Question

I´d like to SELECT a single value into a variable. I´d tried to following:

DECLARE myvar INT(4);

-- immediately returns some syntax error.<

I ran into this same issue, but I think I know what's causing the confusion. If you use MySql Query Analyzer, you can do this just fine:

SELECT myvalue 
INTO @myvar 
FROM mytable 
WHERE anothervalue = 1;

However, if you put that same query in MySql Workbench, it will throw a syntax error. I don't know why they would be different, but they are. To work around the problem in MySql Workbench, you can rewrite the query like this:

SELECT @myvar:=myvalue
FROM mytable
WHERE anothervalue = 1;
