Hi,
Egor has right and i didn't read very carefully you e-mail.Sorry
You can try this :
SET @a:=0;
SET @b:=0;
SELECT @a:=COUNT(*),@b:=sekce.id FROM odkaz,sekce WHERE odkaz.sekce_id =
sekce.id;
UPDATE sekce SET pocet = @a WHERE id= @b;
Now...i think it's corect...

SET @a:=0; --initialize variable a;
select @:=COUNT(*) from odkaz where odkaz.sekce_id = sekce.id;
