Hi
We installed version 4.1.0-alpha-max-nt and try to run a query with a
subquery and get the message

Are subqueries supporeted in 4.1 as is mentioned in the doc or not?
Thanks in advance.
Dear lists,

Hi Ketvin,
after you created your database kelvin_db for example,
you can set a account to use this database in this manner :
GRANT ALL PRIVILEGES ON user_name.* TO @localhost identified by
'password_for_user';
GRANT ALL PRIVILEGES ON user_name.* TO @% identified by
'password_for_user';

our database is about 20 Gb and growing daily. so far, I still see
nearly constant time query performance on tables with ~10M rows. I
don't think mysql is limited by file size per se.
I guess performance depends a lot on what your tables look like, and
your hardware, obviously. From my own

Similarly, you can also use GROUP BY
SELECT WHAT FROM TRANSACTION WHERE REGDATE Now() -INTERVAL 15 DAY
GROUP BY WHAT
The benefit of using GROUP BY as opposed to DISTINCT is that you can use the
set of functions that work on groups like COUNT, SUM, MIN, MAX, etc...
SELECT WHAT,
However, you can use HAVING. HAVING is post-processed, in a brute force
method (no indexes can be used).
Select invno, invdate, invamt, left(invdate,2) as month from
salesfile HAVING month = '01'
But I would use Roger's example since it can take advantage of indexes.
