I've actually been keeping an archive of the MySQL list for quite a while in anticipation of doing this some day. Just doin' my bit... The archive is at http://archive.workmate.ca/myarchive It's still in BETA, so this is a test release to see how it holds up. It's fully searchable on Subject or Body, on the From address, and by date range. It's running on a reasonably decent box (a Sun Ultra 1), but on a fairly slow connection (for now). The pages are quite compact, though, so as long as not everybody hits it at once, it should give pretty decent performance. : Written in Perl with MySQL as the backend, of course. : The archive is updated in real-time as the mails arrive, so it should always be up-to-the-minute. Take a minute and let me know what you think -- it's a work in progress, and feedback is appreciated.

Etienne A valid concern, Etienne, and one that's very important to me, too. Word's fail me in describing how much I detest spam -- well, at least polite ones do. :-/ I believe our information is safe in this case, though. Let me explain why: To the best of my knowledge, Email harvesting 'bots (spambots) use technology similar to that used by the big web search engines. Those companies, like Google, Yahoo, etc., run two main pieces of software; one (a 'spider') that continually accesses all the sites on the web -- well, they hope it's all of them -- and stores information about, or a complete copy of, each page they find. These pages are stored in their database on their big, fire-breathing computers (it's a staggering amount of data) and that's what the _other_ piece of software, the search engine, looks through when you do a search. The spambots do basically the same thing -- they gather up web pages. They, however, simply extract anything that looks like an email address. These lower-than-pond-scum then add that to their database (350 MILLION TARGETTED EMAIL ADDRSSES FOR ONLY $399.00!) and lie that you 'opted-in' or 'expressed an interest.' Fortunately, search engine page gatherers and spambots can access only 'static' html pages that exist on a server and can be searched. The pages you see when you search the email archive are safe from 'bots because they don't even _exist_ until you ask for them -- they're generated on-the-fly, on demand, and they're sent directly to your computer. The content of the archive is visible only to the person doing the search. So, it's a 99% solution. There's still the chance that an unscrupulous person could go to the effort of doing an archive search in the hopes of getting some email addresses to spam, but that's simply not their style; that's too much like legitimate work. Pirating email addresses is 'profitable' (I guess) if they let a computer do all the work; it's not if a person has to write them down or type them in. There are places that DO put the contents of mailing lists up on the web on static, searchable pages. You should be aware of them so you can make better-informed decisions, and thereby have more control over where your address appears. One site with the MySQL list is http://dbforums.com/f114/. Or try, for example, http://www.mail-archive.com/dbi-users@perl.org/msg06361.html For an interesting exercise, you should try going to www.google.com, or your favourite search engine, and doing a web search on your email address and/or your phone number. The hits you get on that search are the prime places where spambots are getting your email address from. I truly believe we're safe, though I'd love to hear more comments.

On a forum you register, you post only when you have question, you have separate areas (installation, query problem, design problems, innoDB problem, let's say) and you can do specific searches. You can also have email notice when a reply is made to a thread you started asking a question. my 2 cents...

[OT] When to un-normalize
Ok let's say I have a table for artists informations. Some artists have two names, let's use know ones, Prince and The Artist I made a table artists that host different info for that artist, then made a table with artistnames where i have artistID and artistName. SELECT artistCity from artists,artistnames WHERE artists.artistID = artistnames.artistID AND artistName = foo; But, since there are maybe less than 1% of artists with many names, I tought maybe i could de-normalize my artists table to put artistName and artistAKA BUT, ever search would have SELECT artistCity FROM artists WHERE artistNAME = foo OR artistAKA = foo Which would disable the index searching because of the OR right?

[OT] mod_perl and last_insert_id() (Was: sequence and nextval)
If running mod_perl does this stay true???
Isn't mod_perl using an already opened connection to do subsequent
manipulations?
Or when one perl script is using a connection is creates a new
connection for each perl script that starts running and if a perl script
finishes, it keeps that same db handle for the next perl script asking a
connection? If this is the case than I magine last_insert_id will always
return the good value..
sorry if this is mod_perl related

It's not possible to mix up the values. The value returned

Re: Performance
Bon apràs-midi René, Well keeping a connection alive is way better on performance.. that is why, under mod_perl, it keeps the connections alive. You should connect at the beginning of the script, and always use that same database handle for the script run. Then close it. Etienne René Fournier wrote: Is it true that mixing HTML and PHP--switching back and forth with ?php ? tags--slows down performance? (I'm using PHP4.) Is it better to echo output than to drop out of PHP mode? And concerning database connections, my ISP asks that I always close a MySQL connection with a mysql_close()--which I can understand. But I'm curious, if I have to make, say, 10 SELECTs throughout a page (in the header, body, and footer), is it perhaps faster to use the mysql_close() at the very end of the page (in the bottom of the footer.inc)? In other words, is there any disadvantage performance-wise (or stability reason) to open and immediately thereafter close mysql connections? Can anyone recommend an article or two on coding techniques for improving PHP and MySQL performance?

Re: [OT] A News Group Perhaps.
Well that's called a forum and it's not at all like a mailing list :-) But yes there could be a forum, but there are already some on the net www.devshed.com have a mySQL part and a Perl part and a PHP part. Plus a forum requires servers, space, web hosting, DNS, maintenance, moderation, programming.. the mailing list is al up and running. I don't like vbulletin, well I don't like the fact that you get the header and wait, wait and wait for the body to display, it's getting the messages out of the DB everytime a user loads a page and the little 3-4 seconds it takes to get the info is annoying :) my 2 cents Etienne Kelly Firkins wrote: I would vote in favor of using vbulletin (www.vbulletin.com) it's got forums for talk like this, web-based, and runs off of the MySQL server as a back-end. An example in action is vbulletin itself or community.installshield.com. Very slick indeed. Kelly FYI, I'm somewhat biased in favor of it because I have set up this program and know how well it works. It's a great example of PHP and MySQL working together. Hi Matt, I am sure this has been said before so my apologies if I bore! Most mail clients let you setup rules. For the mySQL list I automatically redirect all messages into a separate folder based on the [EMAIL PROTECTED] email address. This creates a fabulous resource that can be searched (title and text) and can be read or ignored by choice. I am not a great fan of Newsgroups - they get spammed too much and messages get lost or archived. Some ISPs carry them, some don't. All too hit and miss for a resource on which I rely and am very grateful for.

Thanks, I will definitively look for that But the blocking should be done by the mailing list, making a reply like the one for omitting mysql or database in the message. the message could just ask to put a more descriptive subject. because if every user filters out topics, then the person seeking help would have an hard time finding some.

Re: Index of SET Field

From the Manual:
FIND_IN_SET(str,strlist)
Returns a value 1 to N if the string str is in the list strlist
consisting of N substrings. A string list is a string composed of
substrings separated by `,'
characters. If the first argument is a constant string and the
second is a column of type SET, the FIND_IN_SET() function is optimised
to use bit arithmetic!
Returns 0 if str is not in strlist or if strlist is the empty
string. Returns NULL if either argument is NULL. This function will not
work properly if the first
argument contains a `,':
mysql SELECT FIND_IN_SET('b','a,b,c,d');

[This one is the best one IMO]
or even if you wanna be specific:
mysql SELECT * FROM TEST WHERE place = Whales,North OR place =
Whales,South;
++--+
| id | place|
++--+
| 1 | Whales,North |
| 2 | Whales,South |
++--+
2 rows in set (0.00 sec)

Hi
Thanks for your reply.
I've got the field res_places_sl. It's a SET field that consists of the
following options:
'Wales','North','South'
I was using FIND_IN_SET('Wales',res_places_sl); to access all records that
were categorised under 'Wales' which worked great.
Now, I want to be able to access them from their numerical position. i.e.
if I wanted to access 'Wales' I would ideally want to use something like
FIND_IN_SET('1',res_places_sl);
But that doesn't seem to want to work. The reason I want this is that I
don't want to pass the category name in the URL, but passing a numerical
reference would be ideal.
Is there a way to do this?
Thanks for your help.

Re: mysql round problem
That rule is usually to try and get at the end the most accurate value, if your numbers are evenly distributed your final value will be closer to the good one. So if your values will never have the rounding digit odd so you'll always be discarting half the smallest digit.. at the end of multiple calculations you generate bigger errors. Sometimes one can say, you alternate when having middle values, once you go up, once down... Sometimes it's better to go up, for money calculations, etc This is getting off topic anyways Etienne Dibo Chen wrote: The rounding rule I learnt many years ago said, rounding in 1 if previous digit is odd but discarding it if even. so 9.065 - 9.06, 9.055 - 9,06, ...

Re: mysql round problem
maybe you can add a small value to be sure it rounds up. select round(9.065+.001,2); Always add 1 at the digit after the one you want to keep:) so 9.065 can also be a variable... Etienne Shankar Unni wrote: Attila Soki wrote: select round(9.065,2) ++ | round(9.065,2) | ++ | 9,06 | ++ why not 9,07 ?? Most C compilers today defer things like round() to the floating-point unit on the CPU. Most CPUs these days implement IEEE754 as their FP standard, and IEEE 754 defines several rounding modes that the processor can be set to to define the behavior of the round operation. The default (usually) is round to nearest even (which is what the others have pointed out). You can also set it to round towards zero, round away from zero, or round towards minus infinity. The application is supposed to know what behavior it prefers, and set the default rounding behavior on the FPU by using a specific control instruction. The operating systems are supposed to cooperate by saving and restoring the process' FP rounding preference when restarting the process after an interrupt. Needless to say, there's a fair amount of confusion on this front, and certainly no portable solution, though I believe the latest C standard (C99) has some APIs to control this. The only other choice is to never depend on the FPU rounding, but always call a software FP round routine to perform your rounding, if it's that important. MySQL hasn't done this (and neither have any of the other DB packages I've used recently). -- Shankar. - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

Re: Creating MySQL table w/2 primary keys
that doesn't create two primay keys it uses both colums to form the primary key, which is A LOT different. if you use primary key (a,b) be sure to put a and b not null AND unique. otherwise you could have duplicates in either of these rows. also, if you are fetching rows based on b, it WILL NOT use the index, which is not the intended result. so primary key (a,b) is ok but you need to add either unique key(b) or unique key(b,a) Etienne A.

Re: Query question
I don't get the question..
you just have to compare the values out from the database with the
values from the user input.
my $sth = $dbh-prepare(SELECT usremail, usrStatus from users where
usrName = ?);
$sth-execute(param{'name'});
my ($email,$status) = ($sth-fetchrow_array);
print invalid login if (param{email} ne $email || $active ne 'Y');
Something like that, not tested at all.

Re: ANN: EMS MySQL Manager 1.22 released
I think you are overreacting with your spam thing.
Quoted from the link he gave:
===
This trial version is FULLY functional!
An unregistered copy of the EMS MySQL Manager may be used for evaluation
purposes for a period of 30 (thirty) days following the initial
installation. At the end of the TRIAL PERIOD, the user must either
register the EMS MySQL
Manager or remove it from his system.
===
I mean, It's *directly* related to mySQL.
Put a filter on OT, Off-topic, Ann and you won't see them.

Re: more than one possible column value
hum I have an hard time understanding, but if I'm right: CREATE TABLE files( fileID smallint unsigned auto_increment, filename varchar(36) not null, primary key (fileID) ) CREATE TABLE types( typeID smallint unsigned auto_increment, typename varchar(36) not null, typeext char(4) not null unique, primary key (typeID) ) You'll need a third table linking the two (because it will be a N:N relationship) A file may have many extensions and an extension may have many files. CREATE TABLE filetypes ( fileID smallint unsigned not null, typeID smallint unsigned not null, unique index (fileID,typeID), unique index (typeID,fileID) ) Now insert some dummies mysql select * from files; ++--+ | fileID | filename | ++--+ | 1 | foo | | 2 | bar | | 3 | baz | ++--+ 3 rows in set (0.00 sec) mysql select * from types; ++-+ | typeID | typename| ++-+ | 1 | photoshop image | | 2 | word document | | 3 | excel sheet | | 4 | jpeg image | | 5 | jpeg image | ++-+ 5 rows in set (0.00 sec) Now let's say you have an image that can have either jpeg or jpg: mysql select * from filetypes; +++ | fileID | typeID | +++ | 3 | 1 | | 1 | 2 | | 2 | 4 | | 2 | 5 | +++ 5 rows in set (0.00 sec) mysql SELECT filename, typename, typeext FROM files, types, filetypes WHERE filetypes.fileID = files.fileID AND filetypes.typeID = types.typeID AND filename LIKE bar; +--++-+ | filename | typename | typeext | +--++-+ | bar | jpeg image | jpg | | bar | jpeg image | jpeg| +--++-+ 5 rows in set (0.00 sec) I hope it's what you wanted Etienne btw, if you find any mailing list ont he web for general relational DB design issues, let me know. I searched and could not find any:( Erik Price wrote: Hello, I was looking for some advice on building my database. If this is an offtopic question, I apologize in advance! I'm building a database with several tables. Only two of them pertain to my question. Also, as I have not yet built my tables (I'm planning them), I can't include contents of a dump. One of the tables is called files, the other is called types. Here is a quick sketch of what files looks like (there is more but this is really all that matters): +-+---+-+ | file_id | file_name | type_id | +-+---+-+ | | | | | | | | | | | | | | | | +-+---+-+ here is types: +-+---+-+ | type_id | type_name | ext | +-+---+-+ | | | | | | | | | | | | | | | | +-+---+-+ You can probably figure out what I'm doing here. file_id and type_id are INTEGER-based primary keys which simply give me a nice reference number to give each row. file_name and type_name are VARCHAR(36) columns. files.type_id is really the same as types.type_id, and types.ext is a VARCHAR(5) column. Queries will look like this: SELECT files.file_name FROM files, types WHERE types.ext LIKE txt AND files.type_id = types.type_id ; So that a user can enter txt as a file's extension and all the files that are .txt files will be returned. First of all, I hope I'm doing this right. Second of all -- some files types (file formats) have more than one extension. For instance, I write HTML files and use JPEGs. But sometimes I'll use a graphics program that automatically renames the file .JPG and I won't change it because it's too much of a pain. Or someone I work with might have use Windows, and instead of writing a .html file, they may have their extension as .htm (the l is missing). What is the best way to accommodate all of this? I would like to make the types table a comprehensive list of all file formats with their associate extensions so that when a filename comes up, the user can easily see what format that file is in (and there would be other columns, such as open_in with the name of an application to open that file with; e.g.: Photoshop for .psd or Illustrator for .ai).

Re: more than one possible column value
well I index both because it enables to pull data without even reading on the table.It reads only in the B-Tree index since it's both numeric. There is a section on mySQl optimization in the mySQL guide on the webpage. If you want to find all files that have this or that extension, mySQL will use the (typeID,fileID) index if you are looking for the index of a particular file, it will use the index (fileID, typeID). this is for speed!

Re: Graphical Database Information
I use visio professional... But it's home made, not auto made like with an access DB. Plus since there are not a lot of types from visio, I prefered to make my own drawing, using cool functions like the snapping (so when I move tables they stay linked). Plus the relationship from visio are pretty neat, you can choose One, one (optional), many, many (optional) so ti draws the correct ends: ---||- or ---o|- or ---| or ---o But if you already have a complex DB in mySQl and want to have the graphical equivalent from a click, then I don't know and I'm curious if there is such app. Etienne Steve Osborne wrote: Is there a utility that will allow me to view a mysql database that is similar to an Access 2000 relationship diagram?

Re: LIMIT by column return

General database design
1- What should I index? Index is for speed.. Should I mainly index the columns where I do often searches on them? Should I index all not null columns event if I rarely search using them? Should I index enum columns even if there is a lot of identical data. Will a search using only indexed columns be faster, or it will still go into the table itself to get the data? I read some about it in the guide, but still not clear. 2- Do you think it's better to have 4 small queries or one huge one that returns tons of lines? Let me explain. I have let's say, a main table events with fields evtID, evtName, etc. I have 3 smaller tables outlets, promoters and artists. Those are n:n relations with the events table. An event may have multiple artists, and an artist may be in multiple events. So I created 3 link tables eventoutlets with columns eoEvtID and eoOutID eventpromoters with columns epEvtID and epProID eventartists with columns eaEvtID and eaArtID So, if you still follow me, I want to get the list of artists playing at an event, plus the outlets for tickets and the promoters throwing the event. I can do a HUGE select statement, or make a couple of small ones. select epProID from eventpromoters where epEvtID = '3' select eoProID from eventpromoters where epEvtID = '3' select eaProID from eventpromoters where epEvtID = '3' (some script to store those results) select proName, proInfo from promoters where promoterID = '5' or promoterID = '6' or promoterID = '12' (etc) same for the artists, outlets.. ideally, something like select proName, proInfo from promoters where promoterID = (select eaProID from eventpromoters where epEvtID = '3') would be perfect, assuming it selects for all the occurences where epEvtID is 3 and not just the first one. Anyways, I'm pretty sure nobody went reading this far, I'd just like some input as how you're doing your things with n:n tables. And if you have any mailinglist you know that is more about database design itself..

When creating a table, can we specify that the combinaison of two fields needs to be unique but each of those two fields may have duplicates, just not both the same?

[OT] Comments about my DB layout
Good afternoon, This is my first post on that list, I was looking for relational database mailing list, and found none. So I will post my question here since my database will be under mySQL and users on this list probably have good experiece with DB design. I designed my database, and before all coding the interface, I'd like some experts to have a quick look to it to at least tell me if there are major mistakes in the design. I read Database design for mere mortals a little while ago and this is my first attempt in a real-world and complex (well compared to what I done before) DB. I attached an image copy of the file made with Visio. Visio is made for Access, I managed to get the primary and foreign keys to be as my original sketches (playing with weak and strong tables and identifying or not links) So for the ones interested in my structure, let me know any questions you may have regarding the way everything works and any comments you have.
