RE: Length limit of 500 on primary keys?
The problem is that he has it as a primary key, so he wants it to be unique as well as indexed. The best solution (and MUCH MUCH MUCH more efficient) would be to hash each of the four columns, and create a primary key on that. Integer keys are much faster and memory-efficient than string keys.

Is there a way to raise this limit? We have some tables with columns that are VARCHAR(200), and need to make a primary key based on combinations of these columns (in some cases, upto 4 columns), and MySQL complains for all of these table definitions that Specified key was too long. Max key length is 500. Why do you need to index the entire column? You can just index a prefix of the column, like the first 125 bytes of each column. - 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?

where to put a txt file to fill a table?
Hi, This evening I'd download the complete packet of NuSphere what contains also MySQL. In the tutorial what comes with it, it say that you can make a txt file and save it. With this txt file you can LOAD it in MySQL by using the command: LOAD DATA LOCAL INFILE txt_name.txt INTO TABLE table_name; But it does not tell me where I have to save this txt file. I tried it in several directories, but MySQL cannot find the file. Can you tell me where I have to save the txt file in order to be able to let MySQL load the txt file in the table ? The nusphere directory is located at c:\program files\ To see the directory structure, I had upload a screenshot to http://home.planet.nl/~jool/mysql-dirs.gif Best regards, Olav Wirtz The Netherlands. - 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: Field Naming Standards
I share most of these conventions, and I think the key is consistency. Consistency makes the database usable, without guessing or having to refer back to notes or other uses of the table or field. My golden rules are 1. Key names are unique within the database this avoids any confusion when joining tables. I have one cross-reference table Model_ID int(11) NOT NULL default '0', Model_type_code char(1) default NULL, Country_code char(2) default NULL, Manufacturer_code char(2) default NULL, Range_code char(2) default NULL, Derivative_code char(2) default NULL, Trim_code char(2) default NULL, Engine_code char(2) default NULL, Fuel_system_code char(2) default NULL, Body_type_code char(2) default NULL, Body_doors char(2) default NULL, Transmission_code char(2) default NULL, Intro_date int(11) default NULL, Term_date int(11) default NULL, Modified_when date default NULL, PRIMARY KEY (Model_ID) where almost all the fields are primary keys of other tables. Using 'id' as the primary key for all tables (or duplicating key field names at all) would be a nightmare when you are trying to understand how tables relate to each other if you are working with large numbers of related tables or cross referencing tables. 2. Sequential auto generated ids get 'ID' at the end e.g. 'UserID' I use this as a marker and avoid using them directly to avoid users spoofing them ( update_user.php3?UserID=1Privilage_levelID=2 opens a security risk ) 3. I capitalise first letters of field names. This differentiates fieldnames from variables in php (where I always use lowercase ) which I find makes coding more readable and reduces the risk of errors . 4. I think 'Current_manufacturer_code' is more readable than 'CurrentManufacturerCode' so I prefer _ 5. Use descriptive fieldnames 'Current_manufacturer_code' is more typing, but 'c_man_cd' is meaningless to somebody else or six months later when you come to rework some coding. I also like my SQL to be as close to natural language as possible, for the same reason, and this helps. In the end consistency is essential, much of the rest is personal preference. Peter -Original Message- From: ryc [mailto:[EMAIL PROTECTED]] Sent: 20 October 2001 19:48 To: Mike E; [EMAIL PROTECTED] Subject: Re: Field Naming Standards I am not aware of any document that describes naming conventions, but through my use of databases and design I have found a scheme that works for me. I follow these rules: 1. The autoincrement field (or unique id) for a table is named tablename ++ id. So if the table is books the unique identifier for the row would be bookid. 2. When an attribute in one table is the same as in another table (ie in the table books I might want to reference a row in the author table in which case I would name the attribute in the books table authorid). 3. I use lowercase names for both tables and attributes.. The reason is I am not a big fan of uppcase letters unless they serve a purpose (like in OO the class name would be upper case while methods on the class are lowercase). In SQL there isnt much of a need to diferentiate between a table and a attribute because you can determine easily what the name is from the context in which it was used in the query. But I think this is a preference thing, I could see someone thinking its very useful. 4. When naming an attribute I try to reflect the meaning of the data as much as possible in the attribute name. Because SQL doesnt let you easily convey to the client what the field means, you must do it in the attribute name. So instead of using something like aptno for a field I would choose apartmentnumber. 5. If you use apartmentnumber in one table, make sure to call other references to it apartmentnumber as well... Dont change it to aptno. This follows from rule 2, I just thought I would say it again in another way. :P The same goes for code that uses these attributes. If a variable holds the value from the apartmentnumber attribute, dont call it aptno. It might be clear in this example where that data came from but that may not hold for other examples... and definitly if someone is going over your code who is not familiar with the database it will help (or if you havent looked at the code in a really long time). That is about it for now... anyone care to add? ryan I've been developing in MySQL for some time now, but as I go along I've noticed that my naming conventions have changed dramatically, and I was wondering if there is like a set of guidelines or something I could take a look at. A set of standards, if you will, for naming conventions of fields in tables in MySQL databases. For example, using all lowercase for field names, separating words with underscores, or not, and whether to use a descriptive auto_increment id (such as userid, newsid) or if to just use id for every table.

Re: delete doble quotes from entries?
Does anyone know how to delete double quotes from my entries ''. I thing you can use regular expressions. Dexter, The following resources may be of interest to you: The MySQL Manual, particularly: 7.1 Literals: How to Write Strings and Numbers, 7.4 Functions for Use in Select and Where Clauses, 7.4.6 String Comparison Functions, and 7.4.10 String Functions Also real inspiration in a recent posting on this list (on a similar problem) is RE: UPDATE problem from Steve Meyers to Amit. [That and your question managed to get my 'creative juices' flowing this morning - thanks] The 7.1 manual entry discusses literals, so if you're uncertain about being able to enclose double-quotes () in a string ... Next ambiguity: the word delete might lead you to the SQL command: DELETE. In fact you want to UPDATE your data (by deleting/removing...) The title of the 7.4 manual entry is a great hint as to problem solving methodology - you might be heading for an UPDATE command, but the WHERE clause is common to both SELECT and UPDATE and thus you can use SELECT to build and debug that far - rather than unnecessarily risking errors leading to data corruption and db restores (from that ever elusive backup copy...) While on this topic, you can also work on the SET clause by quoting 'sample data' directly without using a TABLE (many examples in the manual entries listed), so we CAN save databases (as well as the whales!) Next ambiguity: I made the casual assumption that the double quotes in the entries were surrounding strings (ie first and last character of the field). You didn't indicate if this was so, or if they are 'randomly scattered' within the string data - Notice that the WHERE clause below handles both situations, but the SET clause does not!!! The 7.4.6 manual entry discusses the % wild-card character and thus how to build the WHERE clause. The 7.4.10 manual entry lists a whole range of functions - yes you could use a REGEX solution, but (I'm not very good at those and) the simplest approaches are always the best. Have settled on the TRIM command which (I always think is only useful to remove leading/trailing spaces, but) is a multi-purpose tool when you decide which character(s) it should work on. Of course you could also use substring() and length(), etc, etc. Another little gripe: it would be easier if you gave us more information about your data/what you have tried before posting a request on the list. Then we don't have to 'invent' or 'guess' what your data/table looks like! UPDATE tbl_dexter SET str_right = TRIM(BOTH '' FROM str_right) WHERE str_right LIKE '%%'; - the TRIM string argument is single-quote then double-quote then single-quote! If the double-quotes are (also) 'embedded' in string str_right, this won't be enough!

SUMMARY: Problem with myisamchk -- what am I missing?
Hi all, I'd like to thank Gordon Burditt for responding to my question. (Original question below.) It seems I was invoking myisamchk incorrectly. Rather than doing: # myisamchk mailtable ...I was specifying both the data and index files, like this: # myisamchk mailtable.MYD mailtable.MYI I think what confused me was this sentence from the manual (Chapter 15.1 Using myisamchk for Table Maintenance and Crash Recovery, 2nd paragraph): To check/repair MyISAM tables (.MYI and .MYD) you should use the myisamchk utility.

MySQL Performance Question
Dear Sir/Madam. I have written a Management Information System that has a MySQL db running on a Linux server. There is quite a small number of tables. However these tables are growing quickly and the queries executed will require LEFT OUTER JOIN between tables. Example: A sample query over 4 tables using LEFT OUTER JOIN Table A 11000 rows Table B 15000 rows Table C 18000 rows Table D 2,500,000 rows Table D will over a year will reach values of 10 to 15 million records. Are you aware of any benchmarks / examples of expected response time??

Re: shared datafiles.
- Original Message - From: Zachary Denison [EMAIL PROTECTED] To: MySQL ListServe [EMAIL PROTECTED] Sent: Sunday, October 21, 2001 11:11 AM Subject: shared datafiles. I know this is probably a recipe for disaster, but would I be able to have 2 instances of mysql running, both pointing to the same set of datafiles? Before you ask, my reasoning for doing this would be so that I could get some sort of underlying shared mirrored filesystem and this way I could have 2 read/write copies of mysql running in 2 different locations. Why not just create two connection objects within your language of choice? Assuming that your current MySQL server has its own IP address, you can use an ODBC connection, via the IP, and connect to the same MySQL db from virtually anywhere. From an efficiency standpoint, you're much better off creating two connections rather than having two simulatneous servers.

Re: Absolute beginner moving from Access

I use Dreamweaver Ultradev. I cannot get any sort of a connection locally, using PWS and MySQL server. And how exactly were you planning to do that? If memory serves me, Ultradev produces ASP code - is that what you were planning to do? At the very least, you're going to need an ODBC connection (to your MySQL server) on the same machine as the PWS server (which I assume you know how to create). Once the connection is there, you should be able to designate that as your datasource, from within UltraDev. Realize that UltraDev attempts to make use of some ADO properties and methods that are not yet supported by MySQL, but you should be able to create the initial connection fairly easily. If you need an ASP tutorial, let the list know - I'm sure that there are some resources for that already out there.

Proposed Guidelines for Posting to the MySQL list
Hi everyone, There's been some discussion recently on the need for a FAQ and posting guidelines for the MySQL list. I got to thinking about that... : I belong to another list, called the SunMangers list. (I'm sure there's other SunMangers members here. Hi! : ) The SunManagers list is a wonderful resource for getting timely help for those times when you're stuck and just can't get something to work correctly. Some of the top people in the Sun world are on that list, and they can be very generous with their time to help others. That list has been in existence for a *long* time, and is so successful because the members have developed some rules to make it work well. I asked the SunManagers Information Files maintainer, John DiMarco [EMAIL PROTECTED], if I could create a set of guidelines for the MySQL list based on those that are posted regularly to the SunManagers list, and he graciously gave his permission. I'm also volunteering to maintain this document, and to post it periodically to the list. So, here's the proposed Guidelines. Take a look. Thoughts and constructive comments are welcome and encouraged. Flames go to /dev/null : Thanks everybody! -- Guidelines for Posting to the MySQL list - NOTE: This message is posted periodically to the MySQL List on behalf of all members of the MySQL mailing list. Please read it carefully before posting. This document can be retrieved from: [proposed: ftp.workmate.ca] Dear prospective MySQL List poster, We ask your kind co-operation in making the MySQL list a more valuable, effective resource for all of us in our community who use it. Before posting, please stop for a minute and consider whether or not your posting is suitable for the MySQL List. The list is not intended for just any possible question related to database software and development. The only appropriate questions for the MySQL List are questions about the use of the MySQL database software products that are NOT answered in the manuals or system documentation, in the mail archives, or in the MySQL FAQ. These are the rules for posting to the MySQL list: - Remember that busy people are giving their time to help you. Respect that. If you want help from the best, don't waste their time. You are expected to have done your basic homework -- the list is not a place to go because you 'don't have time' to read the manual. The list is there for when you've tried your best, made a real effort, and are genuinely stuck. - You have to repay the favour. You are required to post a single SUMMARY of the email responses to your question. The SUMMARY contains the original question, explains the solution that solved the problem, and names and thanks the folks who helped you. This solution will then be in the archives, available to everyone. This increases our community's store of knowledge, and helps to prevent the same questions from being posted to the list every other day. - Don't post off-topic questions. Eg. PHP questions not directly related to MySQL go to the PHP list. - Replies are directed to the POSTER and not to the list. This keeps traffic and clutter down. - Those who don't post a SUMMARY are likely to find future questions going unanswered. In particular, the following kinds of postings are NOT appropriate: - Subscribe and unsubscribe messages. See your email headers for subscribe and unsubscribe instructions. - Test messages of any sort. - Extended discussions about anything, including discussions about the list itself, or numerous followups to any posting. - Postings not related to MySQL software or its use. Use the appropriate newsgroup or mailing list instead. For example, if your question concerns sendmail, please consult the comp.mail.sendmail newsgroup or the www.sendmail.org website. - General OS, network, or software questions. Use the appropriate newsgroup, eg. comp.unix.questions instead. - Postings that are not time-critical. Postings claiming to be 'URGENT!' when they are not are particularly inappropriate. They are also dishonest and disrespectful of the other list members. - Questions already answered in the Archives or FAQ. Read the Archives or FAQ instead. If you're not sure if the question is in there, please look before asking. You can find the archives at http://lists.mysql.com/ and the FAQ at: [future-location-of-FAQ] - Questions that are answered in the excellent manuals or system documentation. Read the manuals instead. If you're not sure if the question is answered in the manuals, please check first! - Job postings, requests for jobs, sales pitches, etc. Get permission from the MySQL staff first, or use the appropriate newsgroup instead. - Please, no postings in HTML, rich-text-format, Microsoft Word, Word Perfect, or any format that some people on
Some weird problem (aren't they all :-)
Hi there! I have a question. I've created a page in PHP4 which displays the result of the following query: select event_detail.id, event_detail.startdate, event_detail.enddate, event_detail.title, event_detail.comment, event_detail.active, event_detail.subscription_open, event_main.url from event_detail, event_main where event_detail.id_main = event_main.id and startdate '$today' and active = 'Y' order by startdate asc And everything works as it should...up until this weekend where I receive the following error: Warning: Supplied argument is not a valid MySQL result resource in /u284/oneiros/algemeen/agenda.php on line 28 The strange thing is that when I remove the order by line in the query, everything works fine. I've tried recreating the two tables in question but to no avail. Oh, yes. On my local server, I run MySQL version 3.23.41-nt and everything works just fine. The version on the server with the provider is 3.22.21 Many thanks in advance Blessed Be Peter - 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?

Robert Alexander wrote: - Replies are directed to the POSTER and not to the list.

So answers to questions go directly to the poster and are not cc'd to the list? I suppose it's more efficient because each discussion thread has only a question and it's summary both posted by the same author. But won't this make the list a bit sterile? Other authors wont be able to participate in a discussion and there wont be the public aggregation of viewpoints - just a reliance on the original poster (many of whom are newbies) to consolidate all replies they receive and post a coherent summary based on individual emails. I took a look at the SunManager's archive and it seems that many of the questions don't have summary posts. I'm not a subscriber though, so perhaps I missed something. I also find it useful sometimes when browsing the archives to look at all posts in each thread because sometimes they provide insights into related issues. I think summary posts are definitelly a must, but users should be required to cc the list when replying to posts. Also descriptive tags are really useful in the subject. For example the mod_perl (perl under Apache - http://perl.apache.org) list uses the following: --snip-- 5.2.8. It can be helpful if you use a tag [in square brackets] in the Subject: line, as well as the brief description of your post. It does not matter whether you use [UPPER CASE] or [lower case] or even a [Mixture Of Both] in the tag. Some suggested tags are: ADMIN Stuff about running the List. ADVOCACY Promoting the use of mod_perl, printing T-shirts, stuff like that. Please don't start another discussion about whether we should put this on a different list, we've been there before. ANNOUNCE Announcements of new software tools, packages and updates. ASP Joshua Chamas' implementation of Perl embedded in HTML. BENCHMARK Apache/mod_perl performance issues. BUG Report of possible fault in mod_perl or associated software - it's better if you can send a patch instead! DBI Stuff generally concerning Apache/mod_perl interaction with databases. FYI For information only. JOB Any post about mod_perl jobs is welcome as long as it is brief and to the point. Note: Not JOBS. MASON Jonathan Swartz' implementation of Perl embedded in HTML. NEWS Items of news likely to be interesting to mod_perlers. OffTopic Or [OT] Off-topic items, please try to keep traffic low. PATCH Suggested fix for fault in mod_perl or associated software. QUESTION Questions about mod_perl which is not covered by one of the more specific headings. RareModules Occasional reminders about little-used modules on CPAN. RFC Requests for comment from the mod_perl community. SITE Stuff about running the Apache/mod_perl servers. SUMMARY After investigation and perhaps fixing a fault, and after an extended discussion of a specific topic, it is helpful if someone summarizes the thread. Don't be shy, everyone will appreciate the effort. If you can't find a tag which fits your subject, don't worry. If you have a very specific subject to discuss, feel free to choose your own tag, for example [mod_proxy] or [Perl Sections] but remember that the main reasons for the Subject: line are to save people time and to improve the response to your posts. --snip-- - 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: Can Mysql search full text fast through 3.3 million text documents?
In the last episode (Oct 19), Barbara Ferrell said: We have 3.3 million text documents ( U.S. Patents) that we can put into any format needed to import into any database needed. Would Mysql be able to handle fast FULLTEXT searching? Each document has several fields that would need to be searched, for example: we would want to search all 3.3 million documents for the database and relation, and sometimes limit the search to specific fields per document. .the database is about 200 gigs. Mysql 4.0's Fulltext support is not efficient enough for tables with this many records. A better solution for now is to do your own fulltext processing outside of mysql. My solution is to have a mediumint auto_increment value on my main table, then create a words table with this layout: CREATE TABLE words ( id mediumint(9) NOT NULL auto_increment, word varchar(25) NOT NULL, doclist longblob, PRIMARY KEY (id), UNIQUE KEY (word) ) doclist is an array of 4-byte integers representing the docid of each document in the main table containing a particular word. To add a document to the index, you split it into words, pull the doclist for each word, add the document's ID to the doclist, and update MySQL. For more efficient updates, you can process multiple docuemnts at a time, cache the updated 'doclist' arrays between runs, and only update the 'words' table at the end of the run. My method can process about 100 documents/second with flushes every 2000 documents on a p6/200. It would probably go 500 docs/sec if I only flush at the very end of a run, since the majority of the time is spend pulling doclists from mysql. To process queries, you simply pull the doclists of each word in your query and do set math on the arrays. Extremely fast. My test table of 3.5 million 60-byte entries (250 MB table) creates a 50 MB words table with 213000 words. You can cut the size down by 50% by simply compressing the doclist before storing it in mysql. By contrast, creating a Mysql fulltext index on the same data creates a 500MB index, and is 100 times slower to search. -- Dan Nelson [EMAIL PROTECTED] - 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: Proposed Guidelines for Posting to the MySQL list
- Original Message - From: Robert Alexander [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Sunday, October 21, 2001 1:29 PM Subject: Proposed Guidelines for Posting to the MySQL list There's been some discussion recently on the need for a FAQ and posting guidelines for the MySQL list. I got to thinking about that... : That's great! Overall, I think that these guidelines have a lot of merit, but I can't help but feel that they should be coming more from MySQL AB, than the list itself. If they have a vision for the resource that the mailing lists should provide, then its guidelines should come from MySQL AB. - Replies are directed to the POSTER and not to the list. This keeps traffic and clutter down. This is one of the few points I disagree with. The archives of this list, if used properly, is probably one of the best support resources out there right now. One of the reasons is because there tends to be some back-and-forth until a correct answer is determined. Following the thread of responses to a particular query can be of great benefit. The antithesis of this rule is that individual posters MAY NOT be contacted. This prevents the experts on the list from being flooded with direct queries, which does not benefit the list as a whole. I know that when I am directly contacted, either out of the blue or as a follow-up to an answer, I encourage the writer to post to the list since providing answers one-on-one does not benefit the list. Therefore, I would propose that the guidelines include that all questions answers (when relevant) remain on the appropriate MySQL list. - Job postings, requests for jobs, sales pitches, etc. Get permission from the MySQL staff first, or use the appropriate newsgroup instead. If I remember correctly, the MySQL lists are open - you do not have to be a member to post to the list. As long as the lists remain this way, they will always be open to these kinds of postings, including outright spam. There is a filter in place, but my understanding is that any letter beginning with Dear MySQL community: (or some variation containing MySQL) will get through. I think you would have to work with the MySQL staff to really tighten the list to meet stricter requirements. Note also that there's a good chance your question has been answered in the past. Please spend a minute or two checking one of the MySQL List archives, eg. the one at the MySQL site (http://lists.mysql.com/). See above; this archive is a great resource because all answers stay on the list - we should definitely try to keep it this way.

Re: Proposed Guidelines for Posting to the MySQL list
Re: Proposed Guidelines for Posting to the MySQL list - Replies are directed to the POSTER and not to the list. This keeps traffic and clutter down. This I think is the only point that I have an issue with. If you look above, there are two (at least right now) replies posting that this is a bad idea. however if all those replies went to the recepient, I wouldn't have known that this is posted and would post the same thing again. Another problem: suppose there are two solutions: a well known and not so well known. Suppose someone asks something and the first thing people do is send the well known idea. However if that doesn't work, since there is no feedback, noone even thinks to send the secondary rare idea (that might not even come to mind). Also, someones reply might be helpful but not great and someone else on the list might, looking at the reply, come up with an even better posting. The problem here is that usually posters will get a gazillion mails with same reply instead of two or three with possibly unique solutions. All of these lead me to believe that having the replies sent to the list is better and serves the community better. OT: BTW, can you email me a pointer to the SunManagers list? Is it the one at sunmanagers.org? Cause I thought that one was ran by MrBill. If it's that one, then no link is needed, I am subscribed to that one. - 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 system user and permission
PLEASE CC ME BECAUSE I'M NOT IN THE LIST... Thanks! I'm having a problem: ERROR 1017: Can't find file: './mysql/adminedit.frm' (errno: 13) I've searched in the archive and find a solution. It says that is a permission problem and to make all the files owned by mysql.mysql. This works, but I want to make some users to have they own databases.

From http://www.mysql.com/doc/n/o/node_567.html For the connection specified by mysql, mysql_errno() returns the error code for the most recently invoked API function that can succeed or fail.

Binlog rotation for a mysql master server
Something that is not entirely clear about the mysql binary logs in the documentation is whether the mysql daemon itself begins to write logs with different names at different points in time, or if it simply writes to .001 and your logrotate daemon (perhaps as directed by mysql's bundled logrotate scripts) rotates out old files at intervals. The reason that this is confusing to me is because we have two different almost congruent setups, and on one of them the mysql binary logs rotate by themselves (new logs get created at intervals, and all the logs are recorded in the binary log index file) and we can safely restart our master mysql daemon, but on the other setup the logs do not appear to rotate, and restarting the mysql master daemon causes all heck to break loose. The slaves begin trying to read from non-existant log files, and the master truncates the only log file it wants to write to (.001) and starts it over. All the mysql servers we have are version 3.23.36 running on Linux 7.1 kernel 2.4.5 and 2.4.12 (the ones that were rotating correctly were on kernel 2.4.12, but the newest available rpm was 2.4.5 and we're not authorized to run experimental kernels on our production machines). We have a replicate-ignore-wild-tables=mysql.* as our only relevant replication setting. So has anyone else ever seen this kind of problem before, or else could somebody shed some light on what mysql's dogma is so far as when and how it rotates it's binary logs? I'm familiar with how a bloke can purge to to delete older logs, but I'm interested in how the logs get seperated into different files in the first place.

Re: Field Naming Standards
H Jeremy! tblNews intpkNewsID intfkUsersID datPosted varSubject txtContent blnBoolean Wow, that's rather cluttered. I'd rather use a readable standard. Won't it be a bit strange when you run SHOW TABLES and you get a bunch things back all that being with tbl? So make them easier to read such as tbl_news and bln_boolean. Or shorten it a little with tb_news and tx_content. It's not as weird as you think. If you get back a column of stuff all prefixed with tbl_ your eye will simply slide over it and ignore it. The table that is returned -without- a tbl_, or the one with the thl_ typo will stand out like a sore thumb as an obvious error and maybe even help fix whatever problem you're troubleshooting. When you program, do you prefix every variable name with var? Every function name with func? Every macro with mac? Vars, no, because there are more of them than anyting else. The word that -doesn't- have a prefix is a var. :) But everything else, yes. Because even though it's clear in my head 'now' what I'm doing, I *know* that six months down the road when I look at it again I won't remember -anything!- LOL! Been there done that wy too many times to not plan ahead for brain-fade. Do the filenames on your computer all begin with file and folders fldr? No, because I have no files on my computer that aren't files, and I have no subdirectories that don't have a 'd' at the top of the line. :) But I don't have any perl scripts that aren't *.pl or SSI includes that aren't *.inc.

Re: MYSQL CLIENT
Hi June! How can i connect mysql client to the mysql server? Does mysql need to be installed on the client as well? Mysql -is- the client. Mysqld is the server. The client can talk to any server anywhere -if- it has appropriate permissions. You do not need to have mysqld installed locally to talk to a remote database.

what does it mean Open_files?
Hi, after some testing on a new db, I have this status: [root@rachab /root]# mysqladmin e | grep "onn\|pen.*es" | Aborted_connects | 12 | | Connections | 150194 | | Max_used_connections | 24 | | Open_tables | 0 | | Open_files | 7909 | | Opened_tables| 222981 | | Slave_open_temp_tables | 0 | | Threads_connected| 1 | Option open-files-limit is set to 8192. But why Open_files is 7909 when Open_tables is 0 and only one connection (own mysqladmin) is estabilished? Is there any relation in Open_files, Open_tables and Threads_connected? Manual says yes, but these numbers doesn't agree with. Could it rather be Opened_files than Open_files? Kernel shows in /proc/sys/fs/file-nr: 2155180616384 AFAIK there are about 350 open files in system.

Re: Binlog rotation for a mysql master server
On Sun, Oct 21, 2001 at 05:59:47PM -0700, Jesse Thompson wrote: Something that is not entirely clear about the mysql binary logs in the documentation is whether the mysql daemon itself begins to write logs with different names at different points in time, or if it simply writes to .001 and your logrotate daemon (perhaps as directed by mysql's bundled logrotate scripts) rotates out old files at intervals. The binlog can be rotated for several reasons: (1) You hit the maximum size for a binlog file (max_binlog_size), as documented here: http://www.mysql.com/doc/S/H/SHOW_VARIABLES.html (2) You restart the server. (3) You run FLUSH LOGS. http://www.mysql.com/doc/F/L/FLUSH.html (4) You send mysqld a SIGHUP. http://www.mysql.com/doc/F/L/FLUSH.html There are probably others I haven't thought of yet.

Fresh install fails to start - 'host could not be looked up'
I just installed mysql-3.23.43, apache-1.3.22, and php-4.0.6 all from source this evening (on freebsd-4.4-r). When I try to run safe_mysqld I get this; mysqld started Fatal error: Can't change to run as user 'mysql' ; Please check that the user exists! Aboring I see in the file passwd that the user mysql does not indeed exist. I have run /bin/mysql_install_db and it appears to run okay. I checked the online docs but they always refer to running mysql_install_db to set up the mysql user. Is it okay to manually add a new user to FreeBSD called mysql? I tried this but it doesn't work still.

RE: Proposed Guidelines for Posting to the MySQL list
There's been some discussion recently on the need for a FAQ and posting guidelines for the MySQL list. I got to thinking about that... : cut Both already exist: FAQ: http://www.bitbybit.dk/mysqlfaq - although not created and maintained by MySQL AB, I believe it does answer most of the common questions - and I happen to know that the editor is very keen on adding stuff that others are willing to submit :-) Posting guidelines: Read The Fine Manual, ch. 1.2.22 - it's been in there forever, though most people seem to forget to either read or to follow them rant(this goes for some of the @mysql.com people too, especially the point about only including the relevant parts of the original message in a reply)/rant -- Guidelines for Posting to the MySQL list - cut There are some more good points in these guidelines. But seriously: I don't think anyone is willing to read what amounts to two or three printed pages before starting posting. Human beings are simply too lazy to do that, especially when sitting with a problem they need solved yesterday. / Carsten -- Carsten H.

Database Structures
Hello, Hi, I need some help on something here. I need to know the best way to set up this database. I have a site with a bunch of images/reviews. What i want is for registered users to rate and leave reviews themselves. I'm not sure how I should set up this database though. Now, I have a table that holds the user info. Should I create a new table for each image, which holds the user, and his comments/rating? (this seems rather bloated, and inefficient) or should I create a table somehow for all images and keep track of the user comments/ratings another way? Thanks. I've been looking for sites about database structuring and stuff, but no good luck. If anyone could give me sites or their ideas it would be appreciated - 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?
