How to sort a character-type field, numerically
I'm trying to sort a SQL table that contains a character-type field that contains mostly numbers. This field always contains either a number or a number followed by a character. Like '57' or '57a'. I'd like to sort the table *numerically* on this field, not *alphabetically* on this field. That is, I'd like the table to be sorted like: 1 ... 2a ... 3 ... 4d ... NOT like: 1 ... 11 ... 111a ... 2a ... 22 ... See what I mean? This is a common problem, I think, when you sort an character type field that contains numbers. The sort comes out all wrong. It would be great if I could get rid of the characters, then I could make the field a pure integer and the sort would work great, but that's not possible (or easily possible.) A pseudo-code solution would be SELECT * FROM table ORDER BY INT(char-field), but unfortunately even MySql doesn't have such an INT() cast funtion. I'm asking this perl group, because I suspect that my only solution is to sort the result set in perl. Am I right about this??? Thanks. -- John -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: How to sort a character-type field, numerically
Well, right now I'm doing the sort in SQL. That's the problem. Since its a character-type field, I can't get MySQL to sort properly. I guess I could use DBI::fetchall_arrayref to fetch all the data at once, then sort the array of records the way I need them. However, what I'm hoping for is some SQL expert to tell me this would be a silly approach! -- John -Original Message- From: Wagner, David --- Senior Programmer Analyst --- WGO [mailto:[EMAIL PROTECTED]] Sent: Wednesday, September 25, 2002 4:48 PM To: 'John Almberg'; Beginners Subject: RE: How to sort a character-type field, numerically You should be able to sort it numerically if I understand where the data is coming from. Could you provide a snippet of the code and from there it should not be that hard to provide code to sort numerically.

RE: file upload to MySql
You can do the upload with a form. Read any HTML reference and check out the input type=file tag. The web server will store the uploaded file as a temporary file. Your form handler will have to store it someplace permanent. This is pretty simple using the CGI module. Check out the CGI module documentation for complete details. Once you've got the file on your machine, you can either save the whole file in the database as a BLOB, though I've never done that. I just leave the file in a directory and store the name of the file in the database. A lot simpler, really, though you have to remember to delete the file when you delete the record. Hope this helps . . . -- John -Original Message- From: Mariusz [mailto:[EMAIL PROTECTED]] Sent: Friday, September 20, 2002 8:35 PM To: perl Subject: file upload to MySql I need to upload a file to a database. Could someone tell me how to do it? I know how to insert values into a table and upload files to a directory but how to combine the two correctly so the file gets uploaded to my MySql DB and I don't get any errors.

RE: How To Build A Perl Message Board From Scratch
Simple . . . 1. Get a CS degree at the technical university of your choice. 2. While you're there, do some web programming for fun and to put some of the things you learn to practical use. 3. After graduation, get a job -- preferably in a UNIX/LINUX shop -- so you can hone your practical skills and learn the tricks of the trade from your more experienced colleagues. Do some more web programming ... just for fun. 4. Then, if NT is still around (it's a foregone conclusion that Unix will be there, but NT, no), it should be a reasonably simple (if painful) exercise to build your message board (from scratch) in perl, on NT 2010 (or whatever the then-current version is.)

Finding modules . . .
Luckily this is a beginning perl list, because I'm sure this is a real beginners question . . . I believe I have the Mail::Mailer module installed on my system because when I run 'perldoc Mail::Mailer' I get the documentation. However, when I try to 'use' the module, I get the following error message: [Thu Aug 15 12:08:27 2002] Mailer.pm: Can't locate Mail/Mailer.pm in @INC (@INC contains: /usr/lib/perl5/i686-linux/5.00401 /usr/lib/perl5 /usr/lib/perl5/site_perl/i686-linux /usr/lib/perl5/site_perl .) at support.cgi line 6. BEGIN failed--compilation aborted at support.cgi line 6. I know how to change the @INC search path, but I'll be darned if I can find the path to the Mailer module. I've tried using find as follows: find `perl -e 'print @INC'` -name '*.pm' -print |grep 'Mailer' but believe this is just looking in the same @INC path, so no surprise that it can't find it, either. Any other ideas??? Thanks! -- John -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Finding modules . . .
Thanks, that worked. The path is: /usr/lib/perl5.6/site-perl/5.6.1/Mail/Mailer.pm Now here's the funny part . . . running 'perl5 test.cgi' works, but running 'perl test.cgi' yields the error. I'm guessing that these two different versions of perl search different @INC paths and Mailer.PM isn't on the 'perl' include path. The problem is, the web server seems to use the earlier version (5.004_01) of perl to interpret CGI scripts. Any way to coax Apache into using perl5 to interpret MY CGI scripts?

RE: real beginner's question
This does sound like an ideal job for Perl, but I think you need to give us
more info on what you want to do. For instance, translate all 'i's inside
the braces to 'x's, or substitute one sequence of characters for another. An
example or scenario would be helpful here.

Installing Embperl without root privilages
Has anyone tried to install Embperl without root privilages? I have used embperl on other servers, but am now trying to install it on a shared server. All I really need is embpexec.pl to work off-line. Unfortunatly, when I try to run it, I get the following error message: orange:~/src/Embperl-2.0b6$ embpexec.pl Can't find loadable object for module Embperl in @INC (/home/kemptech/src /home/kemptech/src/Embperl-2.0b6 /usr/lib/perl5/i686-linux/5.00401 /usr/lib/perl5 /usr/lib/perl5/site_perl/i686-linux /usr/lib/perl5/site_perl ..) at ./embpexec.pl line 23 BEGIN failed--compilation aborted at ./embpexec.pl line 23. As you can see, I've set up my environment so @INC includes the path to the install directory (/home/kemptech/src/Embperl-2.0b6). I can't figure out what 'loadable object' it can't find.
