Gleb,
As a sidenote - shouldn't MySQL raise an error when data gets
truncated?
MySQL raises a warning after such ALTER operation. See:
mysql create table dt(a decimal(4,1));
Query OK, 0 rows affected (0.01 sec)
mysql insert into dt set a=999.1;

It looks like MySQL is interpreting your short form join syntax a
different way than you expect. Try using the long form by
specifying which tables and fields you want to join.

How you redefined your project definitely makes your goal much easier to

As I see it, most of what you need to do is related to figuring out how

Im a little confused by the query you posted.. it looks like it would
work, although with many redundant subqueries to get there. From your
requirement, I don't understand why you needs to wrap it in a self-
referencing subquery..
Why does this not give you the same logical value?
Do you have any log messages associated with it?
