Re[4]: RH 7.2 connections problems w 16 web servers to 2 MySQL servers
Hello Sam, Thursday, March 28, 2002, 10:21:39 AM, you wrote: SI The good solution for this would be to put OOPS behind of apache. SI What is OOPS ? The OOPS is squid-like PROXY application which mostly used as WEB accelerator (server side proxy). The main idea of using it with PHP/MYSQL is to decrease number of clients apache has (how many do you have now ?) also this decreases number of needed mysql connections and so number of MySQL threads.This happens because OOPS is able to get result quite fast from the server, buffer it and then slowly push it to dialup client, while the same apache process is able to process other request. SI Is it like SQL Relay ? Others have said that we should be using a SI connection pooler that it's a PHP/Apache config problem that we're SI running into. We may also move to BSD from Redhat. I think you're running into performance problem mostly. At least you should look at VMSTAT output then this problem occures. SI P.S Are you using mysql binary or version compiled with patched GLIBC SI if not the threads limit should be the cause. SI We had to use the patched glibc. We have over 1,000 connections SI supported now. Well. That's what I have afraid of. Unfortunately the Linux has troubles scheduling large number of threads, that's why trying to keep the number of threads as small as possible is good. You can look at the results I've posted to the conference a week or so ago, or do you own once with fork_XXX.pl scripts coming with mysql distribution. The solutions for this problem I have so far are: - Trying to decrease number of running threads using OOPS as I advised, decreasing timeout, limiting number of mysql_pconnect in PHP config and so on. Also one of often errors about this is using objects which connect to MySQL in PHP - remember they would open more connection to mysql then not passed/returned by reference. - Try to Speed up threads handling. You may use Ingo's sheduler available for recent kernels or NGPT thread package. Therefore this packages are not quite well tested with mysql yet. SI - Sam.

This does not explain the mysql lock itself, but may be the reason (i.e too many threads may make mysql to lock or crush because of GLIBC limits) The good solution for this would be to put OOPS behind of apache. This gives two positive issues: - your apache server will have much less children and so will require much less memory and will basically work faster. In my case the number of children have dropped from 150 to 16 and required memory from about 1G to 200M (I'm running very complicated PHP scripts) - you will need much less number of connections for mysql. In my case the number have dropped from about 500 connections from web server to 50, and load average on mysql server fell from 3.0-4.0 to 0.5-1.0. P.S Are you using mysql binary or version compiled with patched GLIBC if not the threads limit should be the cause. MW Hi! Sam We have a very high volume site (3 million page views a day) that's run Sam on 16 Apache / PHP web servers 2 MySQL servers. We are using PHP with Sam persistent connections.

Sam Sam The failover won't work now as if one MySQL goes down the cost of the 8 Sam web servers switching over is so high the other MySQL locks up. Sam Sam Each Apache / PHP server takes up hundreds of connections even when Sam they're idle so we ran into the Linux connection limit of 1000 had to Sam recompile to get past that.

New Problem with LAMP
Hi there
The database is now running, i've created my tables and put the data
inside. This is fine.
Next step is to create a PHP-Website which communicates with the
database, but i am not able to connect over my apache (this is what it
seems to me).
to log into the database I use
mysql -p dkv
(password is ppp
user is dcp)
anything is ok.
my php-script looks like this:
?php
$host = localhost;
$user = dcp;
$pass = ppp;
$conex = mysql_connect($host, $user, $pass);
if($conex)
{
echo Connection established.br\n;
mysql_close();
}
else
{
echo No Connectionbr;
echo mysql_errno() . : . mysql_error . br;
}
?
If I put this into a file on the server and access it with my browser,
I get this error:
Warning: Can't connect to local MySQL server through socket
'/tmp/mysql.sock' (2) in /eshop/apache/share/htdocs/sql/ connect.php on

through socket '/tmp/mysql.sock' (2)

What am I doing wrong? Could it be, that i don't have the necessary
modules loaded into my apache? I am new to this, please be kind with me

Hi!
Check your my.cnf file for the line :
socket = path to sock
Then change the path to /tmp/mysql.sock or create a symbolic link
/tmp/mysql.sock to the path that was inthere.
Restart mysql and that should get you going.

RE: To run MySQL Server from the remote machine
* Chetan Lavti Is it possible to run the MySQL Server from the remote machine..?? Mysql provides a Api's for shutting down the server from the remote place i.e. ( mysql_shutdown(mysqlhadler)) but I can't see any api for starting the Mysql server from the remote machine. The client needs to connect to the server _before_ it can send any commands to it... thus the server must be running before the client can send any commands, and a 'start server' command does not make any sense. Does it mean that every time when I have to run the server it will be done manually... The server can be started manually or automatically. If it is not started automatically, you will have to start it manually before you can use it, yes...

Yes, in php:

Database Design Question
Hi all, I am in the process of designing a MySQL database that will run on Redhat 7.1, but I am fairly sketchy on MySQL and performance. What I want to do is have a database that keeps track of large distribution lists. Each list has a unique ID, an owner (which is a reference to an ID in another table) and a creation date. My question is this: Would it be more efficient to have each entry in the list stored in this table in the database, or would I be better off having a reference to a file that is stored on the hard disk? Users must be able to view, add, modify and delete entire lists and single entries in the lists. I am using MySQL, PHP and Perl with an Apache Webserver.

I have been working with this script (mysql_setpermissions.pl) for a while
and I chanded the path for my.cnf because in Winnt Mysql uses my.ini and
that is used for the admin program. Mysql does not automaticly use my.cnf,
so I set the path. The error I get know is:
The specified CGI application misbehaved by not returning a complete set of
HTTP headers. The headers it did return are:
syntax error at F:\web\cgi-bin\mysql_setpermission.pl line 71, near
exit(0); # the end.

Can't use global $_ in my at F:\web\cgi-bin\mysql_setpermission.pl line
102, near = $_
syntax error at F:\web\cgi-bin\mysql_setpermission.pl line 118, near }

Subject: sql
I am a new comer to the sql world. I have some but brief knowledge of
perl.
here goes!
I am using mysql on a Winnt platform and I have perl 5 installed on it.
I
did setup dbi in perl and I know that mod is working. I have been
trying
to
get one of the scripts that came with the copy of mysql
(mysql_setpermissions.pl) to work. I have it in my cgi-bin (the only
place
I execute perl scripts. When I run this script it does nothing it just
hangs until the cgi times out.
Most of the things I have read about in all the documentation and even
this
mail help is reared for the Unix/Linux users. I have tried to get a
linux
server to work but that is a different issue.
anyways I must be missing some clues to get mysql to talk to my scripts
and
to my web browser. Is there anyone out there with Winnt to mysql
experience

Each list has a unique ID, an owner (which is a reference to an ID in another table) and a creation date. My question is this: Would it be more efficient to have each entry in the list stored in this table in the database, or would I be better off having a reference to a file that is stored on the hard disk? Users must be able to view, add, modify and delete entire lists and single entries in the lists. I would recommend: A table of lists (one row for each list with owner, ID and creation Date (add modification date?)) A table of list entries (one row for each entry) A third table linking the list to list entry. You may have to parse the lists at first to separate the list entries but this method maintains a lot of flexibility: To delete an entire list remove the row from the lists table. This would allow you to maintain the list entries separately or you could also use a DELETE FROM linkingTable WHERE listID=$whatever. Deleting individual records would involve a single row in the list entry table and a DELETE FROM linkingTable WHERE listEntryID=$whatever. You probably would not have to sacrifice speed for flexibility: in small tables (200 records with an index) this type of operation takes less than .001 of a second on my (shared) server.

RE: Database Design Question
-Original Message- From: Ben Holness [mailto:[EMAIL PROTECTED]]On Behalf Of [EMAIL PROTECTED] ... My question is this: Would it be more efficient to have each entry in the list stored in this table in the database, or would I be better off having a reference to a file that is stored on the hard disk? If you mean efficient in terms of performance, the answer depends on how big the data is that would go in the files v. a database record, and how often they'll be accessed. If you mean more efficient in terms of disk space, there's probably little difference if the files are large, but a big difference if there are lots of little ones. How much difference for the latter depends on what file system you're using. In any event, you'll probably have to experiment. If you're talking about a lot of relatively small files, putting the data into database fields will probably win.

Re: Database Design Question
Hi Ben: Performance would definitely be better if you store the data in the database as opposed to simply storing references to files. Sounds like you could solve this with 2 tables with one for the actual lists (assuming the structure of all your list is the same) and the other for the list header info (like owner and creation date).

RE: Database Design Question
Hi Chris/Nick/Scalper, Thanks for the replies. I am not too sure how to implement this in tables, so I will give an example: Let's say I have three lists - a,b and c. List a contains 10,000 entries, list b contains 2,500 entries and list c contains 75,000 entries. I have a table of lists, with list ID, owner and date fields: a,Ben,28/03/2002 b,Ben,28/03/2002 c,Tom,28/03/2002 Then I have another table for each list, with all of the entries. The fields would be list ID and entry: a,entry1 a,entry2 a,entry3 ... b,entry1 b,entry2 ... c,entry1 c,entry2 c,entry3 ... Have I understood the two table concept correctly? How does the third table fit in? I guess that if two (or more) of the entries overlap, I could make things even better by having a multi-value field for the list ID in the second table, allowing: bc,entry65 if entry65 was common to lists b and c ... Is there a limit to the number of values in a multi-value field? (Does MySQL offer multivalue fields?) and would this be appropriate? Cheers, Ben I would recommend: A table of lists (one row for each list with owner, ID and creation Date (add modification date?)) A table of list entries (one row for each entry) A third table linking the list to list entry. - 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?

newbie question about InnoDB
hi, I've downloaded mysql-max-nt v.3.23.49, have setup InnoDB startup support. I am now in the process of creating tables. When these are standard tables no problem, eg: create table test (id integer not null, primary key(id)) type=InnoDB; works fine ! I have problems when I have tables with foreign keys. Here is my sql script: CREATE TABLE answer ( id_answer INTEGER NOT NULL, text_answer VARCHAR (255), id_evaluation INTEGER NOT NULL, id_question INTEGER NOT NULL, scale_answer INTEGER, PRIMARY KEY(id_answer), INDEX evaluation_ind (id_evaluation), INDEX question_ind (id_question), FOREIGN KEY (id_evaluation) REFERENCES evaluation (id_evaluation), FOREIGN KEY (id_question) REFERENCES question (id_question) ) type=InnoDB; There I end up with an error 1005 errno 150 I've seen in the doc that my foreign key syntax might be wrong, but what is wrong ?? Note the same script works fine without type=InnoDB. Any idea ??

RE: hmm
* Harry Rorarius I thought Mysql was a server that could be used as a online database? Yes, it is... If it is, is there some material I have not read that tells me how to do this? Probably :o) I understood most of the information I read about Mysql. I was under the understanding sql is the way to make a online database When you say 'online database' I assume you mean a database accessed through the www, the http protocol part of internet...? There is no http or www functionality in mysql. You must use a programming language or some other tool to link the database with the browser, using the mysql API and usually some CGI library. There are a number of languages to choose between: c, c++, perl, php, python, java, tcl, eiffel, and any language with ODBC support: URL: http://www.mysql.com/doc/C/l/Clients.html There are some examples here, using perl: URL: http://www.mysql.com/doc/P/e/Perl_DBI_Class.html Note that these examples does not show how you make CGI applications, that is a different question. A CGI application is a program running on the web server, using http and a web browser for user interaction. The application can be an 'online database'. The output of the program is usually html (could be xml), the program code is mainly different variations over the sequence: 1) getting the input parameters, 2) prepare some sql statements, 3) execute the statements, 4) collecting the result, and 5) create the final html and present it to the user. Normally you use a CGI library to maintain the http protocol handling, but for output all you really need is to output Content-type: text/html and a blank line before the html. -- Roger - 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: hmm
By the way you're using the terms, I would guess you're hoping to make a new database, and place it on the web. In that case, Mysql is probably at too low a level of detail for your needs. To solve your problem you would need to learn: HTML CGI middleware (ASP, PHP, etc) MySQL SQL database design My guess is you are new to most or all of these. In this case you would do better with one of these two prepackaged database products: 1. Filemaker Pro http://www.filemaker.com/ 2. Microsoft Access 2000 (you know where) Both give you, to some extent, the ability to construct a database, configure the interface, and put it on the web, without knowing much SQL, middleware, etc. In the case of Filemaker, you don't even need to know HTML or be artistic.

Re: [Newbie] MATCH and INDEX question (using a JOIN in a MATCH statement)
Well after some pondering I found a pretty easy work around:
SELECT main.id, description, maincat.name, subcat.name from main
LEFT JOIN maincat ON maincat.id=main.maincatid
LEFT JOIN subcat ON subcat.id=main.subcatid
WHERE MATCH (description) AGAINST ('keywords')
OR
WHERE MATCH (maincat.name) AGAINST ('keywords')
OR
WHERE MATCH (subcat.name) AGAINST ('keywords')
You can even add the MATCHes to your select to get a total relavence:
(MATCH (description) AGAINST ('keywords') + MATCH (maincat.name) AGAINST
('keywords') + MATCH (subcat.name) AGAINST ('keywords')) as relavence
which you can also sort by.
I hope this helps somebody.

This is a follow-up to a MySQL keyword text search question I had answer a
few days ago.
I have table 'main' which has two INT columns 'maincat' and 'subcat' which
hold an index number from to other tables maincat and subcat. These table
each hold descriptive names ('name') for each of the main categories and sub
categories.
I have no problem using MATCH to search the various fields of 'main' using
an INDEX. The problem is I want to create a search across the related
'name' fields of the other two tables.
Here is what I have so far:
select main.id, description, maincat.name, subcat.name from main LEFT JOIN
clients ON forsale.clientid=clients.id WHERE MATCH (description) AGAINST
('keywords')
This works but I can only MATCH in the columns of 'main'.
Now my first thought was to try this:
select main.id, description, maincat.name, subcat.name from main LEFT JOIN
clients ON forsale.clientid=clients.id WHERE MATCH (description,
maincat.name, subcat.name) AGAINST ('keywords')
Which results in an error.
Can anyone tell me if I can do this using MATCH?
Nope.
The columns named in the MATCH() must match the columns for a FULLTEXT
index, and indexes don't cross tables.
Thanks,
Dan

RE: Database Design Question
In your situation (or any situation, IMHO), multi-value fields defeat the purpose of good database design. I think you are on the right track if you are willing to tolerate a little redundancy for the sake of simplicity (as a one-to-many relationship). If you really want to structure it as a many-to-many relationship, then try the following (I throw my 2 cents without knowing exactly what you are dealing with in terms of data structures): Table 1: list (entity table) listId, owner, date, ... Table 2: entry (entity table) entryId, entryDetails (attribute 1, 2, 3, ...)... Note: Lump all entries from different lists together and use an auto_increment primary key and a unique key constraint for every entry. Table 3: listEntry (relation table) listId, entryId Such as: A, entry10 B, entry20 B, entry65 C, entry65 D, entry50 Note: Make (listId, entryId) a primary key or at least a unique key. Hope this helps. Jack --- Ben Holness [EMAIL PROTECTED] wrote: Hi Chris/Nick/Scalper, Thanks for the replies. I am not too sure how to implement this in tables, so I will give an example: Let's say I have three lists - a,b and c. List a contains 10,000 entries, list b contains 2,500 entries and list c contains 75,000 entries. I have a table of lists, with list ID, owner and date fields: a,Ben,28/03/2002 b,Ben,28/03/2002 c,Tom,28/03/2002 Then I have another table for each list, with all of the entries. The fields would be list ID and entry: a,entry1 a,entry2 a,entry3 ... b,entry1 b,entry2 ... c,entry1 c,entry2 c,entry3 ... Have I understood the two table concept correctly? How does the third table fit in? I guess that if two (or more) of the entries overlap, I could make things even better by having a multi-value field for the list ID in the second table, allowing: bc,entry65 if entry65 was common to lists b and c ... Is there a limit to the number of values in a multi-value field? (Does MySQL offer multivalue fields?) and would this be appropriate?

Hi Philip,
before running your test next time try this:
vi /etc/my.cnf
insert into this file:
[mysqld]
default-character-set = swe7
then stop mysql (mysqladmin shutdown)
and restart (safe_mysqld)
then try your test again. It worked fine for me.

RE: Database Design Question
-Original Message- From: DL Neil [mailto:[EMAIL PROTECTED]] ... Which begs the questions: - in what way are you analyzing behavior? and - in what way are you analyzing this list-community? There's too much to read, is the simple answer to the first question. Over the last few years, I've developed some methods of identifying the most influential people in on-line discussions by discovering social networks. Among them, I'm quite sure, are people who are opinion leaders. By identifying them, it's possible to track ideas and trends. Not long after I first started doing this, I did some brainstorming about it with O'Reilly Associates, which uses such techniques to help decide which open source projects have momentum, so that they can make better decisions about what books to publish. In fact, MySQL v. mSQL was one of the early areas they studied. I also started a company, Opion Inc., to do this kind of analysis for the stock market, movies and other areas. Opion recently sold its technology to Intelliseek (and I have no idea what they're doing with it, but it's not hard to imagine). They seem to have a server on-line at www.opion.com, but it's secured. As for this community, my analysis is limited to reading the messages that either have interesting subjects or senders. By eyeballing the folder that contains them, that is, since my software tries to figure out what's interesting as well. Just to put some fears to rest, which usually come up quickly, I long ago recognized that the list of influential people is something of a spammer's dream. Equally long ago, it was obvious that such lists have to be unavailable to anyone else. It's an interesting, familiar paradox -- how to use the data without revealing enough that it could be abused. I don't want to get any further into the various issues around this research here unless it has something to do directly with MySQL.

Re: select a certain num of items in sql query
From: Aman Raheja [EMAIL PROTECTED] Suppose I want to select items 10 to 30 from a table tab, which has 36 rows. What could be the sql query ? Thank you. Aman PS: I am using cgi-perl. How are these items identified as items 10 to 30 in the table? Does that mean that when you SELECT * FROM the table, those are the items that are displayed in rows 10-30? If so, you shouldn't depend on them being as such. It's much better to always have an ORDER BY fieldname clause in your query. At any rate, though, you can specify a range with LIMIT offset,numrows, such as this: SELECT * FROM tablename ORDER BY field1 LIMIT 10; (selects rows 1-10) SELECT * FROM tablename ORDER BY field1 LIMIT 10,20; (selects rows 11-20) SELECT * FROM tablename ORDER BY field1 LIMIT 20,30; (selects rows 21-30) SELECT * FROM tablename ORDER BY field1 LIMIT 9,20; (selects rows 10-30) -- denonymous www.coldcircuit.net - 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?

MYSQL REPLICATION
I am trying to configure mysql for redundancy using replication and the built-in mysql master/slave configuration. What I don't understand, even after much reading, is how to recover from a failure. If host B is slave to host A, and A goes down, B could then be manually or automatically configured to be master itself, and thus take over A's role completely. However, if B was not completely caught up from A before the failure took place, then once A was back up the two would be out of sync, and A could contain data B did not, and B would undoubtedly contain data A did not. How do you avoid this situation or re-sync the two after a failure like this? I'm finding it difficult to locate a concise and cohesive method to create a redundant database system using mysql. Any other resources or references would be heartily appreciated.

Re: MYSQL REPLICATION
Let's say A and B are running together. Then someone does a large update query and A is done with, while B is in the middle of it, and A crashes. You can switch over to B, which won't contain the data, but it'll have a good snapshot of what the data was before the crash. When you recover the A machine, ( if you recover it.. ) and restart, B will catch up from where A left off. Remember, however, that if you update B while A is down, A won't have that data. ( Which is what I think you're asking about? ) This is like any backup solution or when you are replicating anywhere for redundancy. You can only backup so much before a crash happens. When you do crash, then you at least have a good starting point of data. If you're asking about an actual recovery process.. Let's say B becomes the master machine for awhile. When the A machine is recovered, you take a snapshot of B's data and put it over on A. Then start A and have it slave to B and it will catch up from that point. If you want actual instructions, just think of creating A as a new slave to B. Follow the instructions in the mysql docs about creating a slave. -- sh On Thu, 2002-03-28 at 14:54, Joe Bifano wrote: I am trying to configure mysql for redundancy using replication and the built-in mysql master/slave configuration.

Yes, in php:
function tableexists($tbl) {
$res = @mysql_query( SELECT count(*) FROM $tbl);
return ($res ? true : false);
}
Don,
There may be a way to improve your function. Change the select
statement to Select 1 from $tbl LIMIT 1. Because some table types like
InnoDb will physically count the rows in the table and can take several
seconds or even minutes. Selecting a constant is extremely fast especially
with the LIMIT of 1. If the table doesn't exist you get an error. Works for
me. ;-)

Re: MYSQL REPLICATION
Joe, Replication is pretty much instantaneous (depending on network speed), since the servers communicate using the binary log files. Having said that, there is no replication scheme for any database product that can guarantee (over asynchronous replication) that some data won't be lost or mangled in the event of a true problem. If you are looking for this type of replication, you have to go to hardware and synchronous networks (the connection between the boxes is as fast as the local changes). Since this is a MySQL list, you probably aren't interested in huge EMC Symmetrix system doing your replication ;) To deal with the recovery process after the fall simply take the data directory from the surviving slave and migrate it to the master, restart the replication and off you go. Please note that this applies to current versions of MySQL (3.2x) and is changing the new (4.x) tree.

auto_increment question
This is my first time posting to this list, so please forgive me if I am not doing this correctly. I will break this into post into two parts: what i want to know and why. Is there a way to get auto_increment fields to fill in gaps in the numbering sequence if some records have been deleted? Here is an example of my problem: I have two tables in MySQL: 1.web_hits: date datetime not null, client mediumint unsigned not null, URL varchar(500) not null 2.clients: idx mediumint unsigned not null unique auto_increment, name varchar(255) not null web_hits holds information about web traffic on our network. There are more fields that what i have listed, but this is all that is needed for this example. It records the time of the web hit, the URL, and the ID of person who made the hit. The ID can be looked up in the clients table. Now, after a while the web_hits table starts to get really big, because of this we start deleting the old entries from the web_hits table based on the date field. Because of this deletion some clients in the clients table may not be used any more. So we have a query that will delete those from the clients table as well. Now, because of this deletion, there are sequence gaps in the idx field. We would like to be able to use those numbers again for incoming clients...Is this possible?

Re: client dependent timezone
Per client? Per database? The only timezone setting in the MySQL manual is for the server (tz), and permits you to set it to your local timezone so it does not return values in GMT.

I am not sure if JOIN is even what i am looking for here. To do this, i am assuming both tables have the exact same number of records. Any ideas on how i can do this?

Two tables, which did not match?
I have a question about determining which case occurred when there are no matches - using two tables. Scenario: - two tables, one for photos, and one for collections - zero or more photos can belong to a collection - the database may not know the collection_id requested (i.e. the user on the browser side did something to request a non-existent collection) We can hit: a) no collection b) a collection that hasn't had any photos moved/uploaded to it yet, or.. c) a collection with one or more photos (the normal, everything's fine case) Here's the php setting up the query... // shortened version for posting question... // there are many more fields... $sql_str =EOD select photo.photo_id AS photo_id, collection.collection_dir AS collection_dir from photo, collection where photo.collection_id = $collection and collection.collection_id = $collection EOD; $sql_result = $db-query($sql_str); When I check the number of rows returned, and get 0, I have no way (yet) of knowing why (no collection, or just no photos in a collection).

database design
Subject: database design From: deco [EMAIL PROTECTED] === I'm having a problem getting this to fit... I have a file with a bunch of data stored... This data represents messages, one after the other, with message header followed by message data. I'm porting this to a mysql database. The thing is the message data is defined in an external file, which defines foi each message type a bunch of fields that can be double, long, short, ushort, etc... I can parse this file easily, and i'm storing this data in java with no difficulty. The thing is: My DB would be something like: A table holding data types (not programming types, but data types), which holds information about every type that can appear in a file... Another one where values read from the file are stored, with a foreign key to the corresponding data type. Thing is: if the value for this data types can be a double, or a long, or a char, or a short, if my table is like (data_type, value) what field type would i give to value? Cause it can be a lot of things. I can put the biggest one, but then i would be using a lot more space to hold the db than i would need. I was hoping for some possibility of a dynamic size field, that could answer to my needs... Maybe i'll need to set it as a binary object or something. Any help?

Re: Re[2]: client dependent timezone
Depends on the language you are writing in, and the level of your programming skills. If your users/guests have database entries, it would be a rather trivial task to set their timezone in a column in the database, then write your app to calculate their local time based on the offset from GMT. You would either have to rely on the user to use a form or image map of some sort to select a timezone (ala Red Hat's installer), or devise a way to ready the clock on their local machine. IMHO, this is a programming problem as opposed to a MySQL database issue. - Original Message - From: Maxim Vysotskiy [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Thursday, March 28, 2002 7:14 PM Subject: Re[2]: client dependent timezone Hello Gerald, But how people build web-applications then ?

Re: auto_increment question
Jeff Habermann asked: well. Now, because of this deletion, there are sequence gaps in the "idx" field. We would like to be able to use those numbers again for incoming clients...Is this possible? It looks like you can, but IMHO, it would probably be more effective to add a DELETED flag to your records, and just have your routine that adds new records look for records with the DELETED flag set before it tries an insert. The WHERE clauses in your normal queries would include 'DELETED = 0' to filter out the deleted records. Another possibility is to make your index (in this case, client ID) so huge that you don't care if there are gaps. An unsigned INT (instead of MEDIUMINT) will give you so many keys that it will take over thirteen years at an average ten new clients per second to overflow.
