in dialect 3 only.
2. BREAK statement has been disabled in triggers (like EXIT) because of the known
BLR limitations. I hope it can be safely used in stored procedures though, hence
I'd prefer to have it officially documented.
3. More complete implementation of the GROUP BY clause. You can group by internal
functions and have ability to use more complex grouping conditions than before.
By Arno Brinkman.
4. Allowed declaring and defining local variables at the same time.
By Claudio Valderrama.
Syntax: declare [variable] <var_name> <var_type> [{= | default} <default_value>]
5. Allowed ordinals to be used in the GROUP BY clause (like ORDER BY).
By Arno Brinkman.
Example: select extract(month from order_date), sum(order_sum) from orders group by 1
6. The first approach to the ALTER VIEW statement. Only high-level implementation so far.
A lot of work in dfw.epp, metd.epp, etc. still required.
By Dmitry Yemanov.
