Is it possible to do an ORDER BY column_a column_b ASC ? IE Can you
specify two columns to cause the output to be displayed in a specific
order? Ron

Yes!
Just separate your columns with commas!
Check out the proper sintax!!

Yes (a quick search would have told you this too).
It's best to specify the order for each one:
order by column_a asc, column_b asc;
or
order by column_a asc, column_b desc;
for example.

Hi!!
I'm thinking abou to store MP3 files and PDF files in BLOB fields in a a
table, Is this a best practice in MySQL?
Or should I just store a reference to a file stored some where in a file
system?
I want to store sermons and preachings, both a PDF and MP3 for reading and
listening on a web site!
Best Regards,
Miguel Guirao

Hello;
I do not think this is best with any database. Simple put you are=20
large chucks of data that you can not do anything with. On access them,=20
they only slow down the server through put. What I prefer to do is store =
the location in the database, and let the web server or front end get it =
directly.

While storin them in the db is acceptable...I have found that the amount of
data to be stored greatly affects the system...therefore I generally do not
store the items in the tables, but provide a reference pointer to those
items out on the filesystem...
