> We are writing a book about MySQL. There will be emphasis on using MySQL
with perl/php, .net & java. The publisher needs lots of emphasis on SPs and
nested subqueries. We need to be able to write about implementing biz rules
using table constraints, which means FKs. Your site says 4.1 is to have
support for nested subQs, SPs and FKs with an alpha in "early 2002", which
is now but 4.0 is still alpha!

> 1. When can we have a 4.1 supporting nested subqueries, SPs & FKs?

InnoDB type tables support foreign keys already in MySQL-3.23. See
http://www.innodb.com/ibman.html#InnoDB_foreign_keys and
http://www.innodb.com/todo.html.

The current source tree of 4.1 already does some SQL subqueries.

An inofficial timetable for stored procedures is 1 year.

> 2. What would be a good way for us to be in your devel/test loop?

Simply download new versions from www.mysql.com, and test the features
mentioned in the changelog in the manuals at
http://www.mysql.com/doc/N/e/News-4.0.x.html and
http://www.innodb.com/ibman.html#InnoDB_history.
