RE: rank newbie looking for SQL forum
Scott Baker recommended the http://www.sqlcourse.com/ URL. I've just completed an overview/review of the course and have recommended it to several people here where I work in response to recent "How can I learn SQL" questions. Good reference. Many thanks.

RE: rank newbie looking for SQL forum
Okay, thanks guys! I'll lob this ball atcha, then:
My main data table is 'trcdatabase2'. I currently use perl programs to get
our in-house exported flat-file database into web-ready shape, but these
can go *really* *slowly*, so I wanted to harness the speed of SQL. I've
created a couple of copies of the table, 'newdatabase' & 'readydatabase'; I
load the flat-text export file directly into 'newdatabase', then I had it
in mind to work various perl/sql transformations upon it which would get
funneled into the empty 'readydatabase' table.
The first thing I wanted to do was export all of the data which is in both
'newdatabase' & 'trcdatabase2' into the 'readydatabase' table. So I'd
basically be moving the rows from the active & web-ready 'trcdatabase2'
into 'readydatabase' if & only if the catalog number ('catalog') was still
included in the newly-uploaded 'newdatabase'. Here was my best guess:
INSERT INTO readydatabase SELECT trcdatabase2.* FROM trcdatabase2,
newdatabase WHERE newdatabase.catalog = trcdatabase2.catalog
This caused horrible problems. It ran & ran, & then I had some type of
monster table ('readydatabase') which nearly kept me from opening the MySQL
shell interpreter, & took about 10 minutes just to DROP.
Did I set up some kind of infinite loop? Is it because I've failed to set
up 'catalog' as a primary key?
If the latter, I've got another problem: I seem to have CREATE, but not
ALTER TABLE privileges. I'm still waiting to hear back from my sysadmin
about this.
I hope to do all sorts of similar comparison transformations, & I'm afraid
I just don't have table linking down conceptually, or something. Any help
would be most appreciated.
They're running MySQL 3.22.32 on Red Hat 5.2, incidentally. TIA!!

I haven't participated, but the site at www.sqlteam.com looks useful and does have a number of forums there.

RE: rank newbie looking for SQL forum
Hi Jason, You have found the right place. No one here minds you asking simple questions, so long as you have checked the manual and the list archive before asking. In particular, Red Hat installs are a frequent topic. This list is supposed to be MySQL specific, but sometimes we get a little side-tracked. Welcome to the MySQL Community - I hope you have as much success with it as we have.

Having lurked for a while, I can see that since this isn't MySQL-specific, there's probably a better forum in which I can attempt to iron out my confusion. Can anyone point me to a mailing list/usenet group where I can ask lots of dumb newbie SQL questions w/o making a major pest of myself? I'll be back here in a short while, when I try to bang my head against a Red Hat MySQL install again.
