Description:        (Possible) SQL miscontruct not flagged
Details:

Hi,

This European afternoon, I was trying to count how many distinct values of a
row in a table exists and put this result in another table.

Instead of writing :

select distinct(ean13),(select count(*)  from fiart where ean13=a.ean13) as
n into zz from fiart as a ;

I wrote :

select distinct(ean13),(select count(*) into zz from fiart where
ean13=a.ean13) as n from fiart as a ;

I am not an expert in the most intricate shades of the SQL language. Should
the SQL interpreter not flag the query as a misconstruct statement and fire
an ERROR (or at least a WARNING) message ? (I'd guess it should).
