I'm redesigning some software that's been in use since 2002. I'll be working
with databases that will start small and grow along the way.
In the old format, data would come to us in mega-big text files that had to be
parsed and manipulated and so on with Perl to remove crap and finally
with
no programming work!

I'm redesigning some software that's been in use since 2002
My MySQL databases are stored in a directory that is with the rest of my
project. I am using rsync to back up the entire project, including the
database files. I'd much rather do it this way than to create files with
mysqldump. Whenever MySQL creates a new database, the file is owned by the

I'm using MySQL 4.0.24-10 on Debian Sarge (Linux, and the stable branch of
Debian, just to clarify). I had a setup of a program I've been working on

I have a query like this:

there some way to make the keyword DISTINCT apply

I posted earlier this week about how to select from two different tables with
an OR -- selecting rows from either table and putting them into one.
That was easily accomplished with a UNION statement (AFTER upgrading to
MySQL 4.0.x).
Now I'm doing almost the opposite. I have two tables,
combinations of columns).
