RANDOM output order???
Hi, I've an actually quite simple problem, so I guess someone might know an answer... I just need a single random result from my query. With an older MySQL-Version this construction worked fine but with the new one not at all: SELECT ... ORDER BY RAND() LIMIT 1 So I tried out this one: SELECT column, ... , RAND() AS random FROM table ORDER BY random I get different random values, but it does not work in combination with ORDER BY - it's just not sorted. So is there any solution for this?!

sub select
Hi, I know sub select would not work correct in 3.23.xx but I have a question to ask. I'd like to find top 10 ranking of my customer by amount (using order clause desc) but there are some customer have the same amount. I was solve this problem by using group by and insert it into temp table, then i use select function join temp table with main table. Could someone tell me the better way for this problem (i'd like to use only 1 sql statement)? SF example sql 1. insert into temp select *, count(*) from customer group by amount desc limit 10 -- this sql generate only 10 row in temp table 2. select customer.* from customer, temp where customer.amount = temp.amount -- this sql may be generate more than 10 row if there are many customer who has the same amount - 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: DELETE returns incorrect value
Gili, if all rows are affected (as in your case) MySQL just discards the whole table content at once so it cannot return the number of affected rows. If you are interested in it put a dummy where clause into your statement such as 'where 10'. That causes MySQL to delete row by row and then it will give you the right number.

RE: three-way join
* mike vogel thanks to all respondents! one more thing, i have 2 foreign keys in the bridge table, but not a primary key. is a primary key in the bridge necessary for this type of join to work? thanks again. Make the two foreign keys the primary key for this table, that way you prevent the possibility of a person subscribing to the same magazine twice... so you may want a 'count'-field or similar in case someone actually want more than one copy of the same magazine. :) Because you probably more often want to see all magazines subscribed for one person, and not so often all persons subscribing for one magazine, the primary key should be defined with the person primary key first: (subs_id,mag_id) Is the primary key necessary to make it work? No... as long as you make sure you do not create duplicate subscriptions (same person subscribing to the same magazine twice). Is there any reason not to define a primary key? -- 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?

Problem with MySQL4.0.1 speed, cpu- and memory-usage
Hello, in order to be able to use the replication features of MySQL we recently gave version 4.0.1alpha a try, since these features are reportedly more reliable in this version - although it is still alpha. Unfortunately the disadvantages - at least on our machines - don't seem to make up for the advantages: we experienced a very high server load combined with higher memory-usage than usual, the average speed dropped to a level the tested databases became almost unusable. Let me explain our setup: we're running a site-internal messaging system that handles approx. 110.000 messages per day. The databases consists of a header and a content table, the first one being a fixed-length MyISAM-table with almost 40.000.000 records, the second one is a dynamic-length MyISAM-table with some 20.000.000 records. We don't use fancy stuff like InnoDB but only very basic SELECT (on indexed columns) and INSERT statements, not even JOINs. The whole thing runs on a 850MHz dual-pentium with 4GB memory under Linux 2.4.17 and RAID1. Until now we used MySQL 3.23.32 which in our tests remains the fastest version so far, all following versions (including 3.23.47 and 4.0.1alpha) remarkably dropped in speed. Now finally to my question: is there a way to speed up 4.0.1alpha (or any other version with reliable replication), maybe a different OS (BSD is reported to be more performant but we have no experience with that so far) could help? Are there any fine-tunings in the ./configure that may have a positive effect (we didn't notice big changes in speed and memory usage when playing with these options)? Usually we would just stick with 3.23.32 but, as mentioned above, we need the slightly more advanced and reliable replication features of its successors in order to be able to distribute read accesses to several slaves while the master does all the writing stuff.

Re: Simple: Date Stamp mySQL and PHP
Oops, got it all wrong. Thought it was a real timestamp, but it's already the date, only formatted in a different way. The date() function expects a Unix-timestamp as its second argument. Thus you could try to leave the conversion to MySQL by using UNIX_TIMESTAMP(your_timestamp_column) or if you want to do it in PHP use mktime(). http://www.php.net/manual/en/function.mktime.php ?php $date1=20020123143547; $date1_year=substr($date1, 0, 4); $date1_month=substr($date1, 4, 2); $date1_day=substr($date1, 6, 2); $date1_hour=substr($date1, 8, 2); $date1_minute=substr($date1, 10, 2); $date1_second=substr($date1, 12, 2); $date=date(d M Y H:i, mktime($date1_hour, $date1_minute, $date1_second, $date1_month, $date1_day, $date1_year); ? Hope that helps Marcus have a look at http://www.php.net/manual/en/function.date.php According to your example, it would be something like: ?php $date1=date(d M Y H:i, 20020123143547); ? - 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: Hoe to create indexes on existing tables
|Hi, | |I'm a bit to Mysql. We are trying to use mysql as a backend for our Visual |Basic application. | |I had a set of tables which I exported from Access database. |But now, I want to index these tables. How do I go about that? | Hi! the simplest solution is to get a GUI client for MySQL, in which indexing or any other operation are as easy to do as with Access... The most famous GUIs are : MASCON, MySQLFront, MySQLGui, DBTools... Otherwise, you can still use the CREATE INDEX clause with commandlines. Check the doc it is very well explained...

The Minifon, developed in the early 1950s by Monske GMBH of Hanover(or by Protona GMBH- I'm not certain), was an ultra-miniaturized, battery operated magnetic recording device. It could not (initially at least) record the full range of sounds and was thus limited to voice recording, but it did offer easy portability in a very small package. The idea of offering a pocket dictating machine was novel, since dictation had previously been done in the office. However, it was thought that people like salesmen could take the machine on the road with them. Once on the market, the Minifon's promoters discovered that many people took advantage of the recorder's small size to make secret recordings to be used as evidence, as in court.BR BR The legitimate use of the Minifon, as a dictating machine, was somewhat problematical. Recordings made on regular dictating equipment were usually letters, and thus were normally sent almost immediately to a typist. The Minifon offered no obvious advantages over standard dictation equipment for office use, but its developers hoped to cultivate new uses for dictation equipment, such as stock taking in warehouses, or the use of the machine as a substitute for note-taking by reporters, insurance adjusters, salesmen, and others. In its original form, the Minifon was a wire recorder, using a type of wire medium developed by the Armour Research Foundation of Chicago and employed in many similar devices since the late 1940s. The machine at its introduction in 1952 had a recording time of one hour, which was remarkably long, and weighed only about 3 pounds at a time when a typical office dictating machine weighed upwards of 10 pounds. It accomplished this small size and light weight in part through the use of miniature tubes and clever mechanical design. The basic machine cost $289.50-- a price that sounds high today but was very much in line with competing office dictating machines. The parent company attempted to set up distribution, sales and service networks in the United States. It established a business office called the Minifon Export Corp in New York, and an existing company, Harvey Radio in New York City became the main distributor. Although smaller tape recorders appeared at about the same time, the main competition in the voice recording field was from an American company, Mohawk, which made a small, battery-operated cartridge tape recorder called the Migetape. Both products sold less than 10,000 units per year in the U.S.BR After a few years, the Minifon was modified to use transistors and magnetic tape, further lowering its weight and cost. By 1962 the basic machine weighed in at only 1.5 pounds. Competition by this time had helped bring the cost down to $249.50. The Minifon after about 1962 was distributed by the international conglomerate ITT through its subsidiary in the U.S., Federal Electric Corp. A little later, distribution was taken over by the ITT Distributor Products Division in Lodi, New Jersey. (I don't know whether these were the same company with different names) By the time ITT became associated with this product, it had taken on the name of Minifon Attache, and a new line of models and options appeared. These included a hi-fi model, the 978H, which sold for $330.50.Usinga two-track, 1/4 inch tape cartridge operating at 1 7/8 inches per second, the machine claimed a frequency response of up to 12,000 Hz, plus or minus 3db. The coming of magnetic tape did not completely displace wire. The Model 240 series of recorders introduced in the early 1960s were probably the last wire recorders in regular production. The 240L, at a price of $269.50 used a special long-playing wire cartridge that held 4 hours of wire. Otherwise it looked like both the tape model and the 240S,
multi-master replication
Will MySQL, at any time in the near future, support multi-master replication? We're looking at splitting some very large databases up among several machines, but we need a way to bring them back together for our stats creation databases on the backend. What we need is a way to combine databases from different machines back onto one database machine, where the databases from the different machines can be joined without the use of daisy chaining to bring it all back together. Is there some way to over come the single master replication limitation now?

I can see that many of those commands follow directly from the C

Yes.
(2) Can someone give me an idea what these correspond to:
Connect Out
Init DB
Change database
Refresh
FLUSH PRIVILEGES
Quit (is this when a client closes the connection?)

Shutdown of MySQL server.

Yes.

DataBreeze for MySQL
Hi all MySQL'ers, We have finally completed our initial public version of the DataBreeze Web Application system that uses MySQL as the underlying SQL database. The system requires Linux(or unix), Apache, Perl, ModPerl and MySQL. As this is a MySQL specific system, feedback from the MySQL community is very important. You may download the software for evaluation at http://www.databreeze.com or simply logon and try DataBreeze directly online. I will offer a developer license to anyone that can show me a unique working DataBreeze system operating within the next week. DataBreeze is very different from typical development tools because it utilizes a pre-built application framework that requires no programming. DataBreeze provides a template environment for building database applications that list, search, explore and edit relational data. The system includes integrated menus, forms, tree-views, security, session/state management and more, all in a Web Browser. DataBreeze can also be extended through the use of Event programs using Perl. Once you create a DataBreeze database and connect to your MySQL Server, you will find Web tools for reading and editing Tables, Columns and Indexes. It also contains step-by-step SQL import/export and text import/export tools based on the MySQL Import/Export utilities. DISCLAIMER: This is not free software but nothing is hidden, the complete Perl source code is included so that you may explore how it works.

Optimizing and more connections
I'm trying to increase the maxium number of connections to my MySQL database but I am not sure how to do this. I've gone to the manual and it doesn't say too much (maybe i'm looking in the wrong spot?). The machine I'm running is an AMD 650 with 512 Ram on RedHat 7.1 and MySQL 3.23.41 so I found the following line in the manual: safe_mysqld -O key_buffer=64M -O table_cache=256 \ -O sort_buffer=4M -O record_buffer=1M However, it seems that I need to shut down the mysql db before I can run this. This still doesn't solve the problem of the max number of connections. I don't have a my.cnf file to change on the server so the only thing I can think of is to tack on -O max_connections=500 at the end of the line above. Is this correct? What do I need to do to maximize the preformance on my machine?

Re: Getting only the latest entries in a table...
Sounds like you have a table (lkup_info) of load dates (date), in which you record fileid (did) and date. Sounds like you do not have a separate table of fileids. I'm assuming that the lkup_info table is updated synchronously with the loading of each file that the table is recording, though you didn't say that. If this table also had an auto-increment numeric primary key (lkup_info_id), and if we had a MySQL version that is still only a gleam in Monty's eye, it would be a piece of cake: SELECT * FROM lkup_info a WHERE a.lkup_info_id IN (SELECT MAX(lkup_info_id) FROM lkup_info b GROUP BY did) In the absence of sub-selects, you will need to do the subsidiary select as a preliminary step, INTO a temporary table. Then do the main select. The pain of modifying the query to work without an auto-increment primary key, and of waiting (and waiting, and waiting) for it to run, will be far worse than the pain of adding an auto-increment primary key if one is not already there. Of course, if the table is not being updated synchronously with loading of the files, all this is probably a pipe dream, for which I apologize. --Erv At 02:06 PM 1/24/2002 -0500, Anthony R. J.

RE: Slow updates with two keys in where.
MySQL can only use 1 index per query. So take your first query for example: update forum set approved='N' where id=644122 or thread=644122 it can only use the id key OR the thread key, not both. and since you have an 'or' in your query MySQL must scan the entire table for either id being 644122 or thread being 644122. thanks, -- Andrew -Original Message- From: Brian Moon [mailto:[EMAIL PROTECTED]] Sent: Thursday, January 24, 2002 3:03 PM To: [EMAIL PROTECTED] Subject: Slow updates with two keys in where.

RE: Tighly packed table
Acck! Yes, please please do that. O(n) instead of O(n^2) (*). This is a much better solution. I was trying to convert 'there exists n such that for all m where n != m, n = m, return n'. Damn logic. (*) To be honest, I'm not even sure what the runtime of my original query was. A good query optimiser would have looked at it, realised I was probably drunk, and just refused to run it.

Efficiently storing md5
Does anyone have a best practices for efficiently storing md5 hash values in MySQL? Since it is a 32 character string of hex numbers, I originally stored them in a char(32) binary column. But that is wasted space (by a factor of 2). And of course, these things add up, both in data files and indexes. Md5 hash-- 16 bytes. char(32) binary -- 32 bytes. BIGINT -- 8 bytes My thought right now is to convert the md5 hash into two BIGINT numbers and visa-versa. High BIGINT = conv(left(md5,16),16,10) Low BIGINT = conv(right(md5,16),16,10) And reversing: Md5 = concat(lpad(conv(high,10,16),16,'0'),lpad(conv(low,10,16),16,'0')) I suppose there is some point (in terms of the number of rows) where storing more efficiently outweighs the conversion functions, and I assume that I'm past that point. Is there a better way to convert these? Just a note: there is no 128-bit integer type and CONV() only works with up to 64-bit 8-byte numbers anyway.

Re: Tighly packed table
I actually have all the records in a 1GB text file, so here comes perl to the rescue!! (Easier than C to me, maybe I'll do it in Java as an exercise.) BTW if anyone has any questions on the ability of MacOS X with medium size DBs. This DB is running on a 500Mhz iMac G3 with 1GB of RAM and Mac OS X. Which is performing as better it seems than the SCO and Linux boxes running the same DBs.

Which is faster VarChar(255) or Text?
I will be putting variable length text into a field (up to 255 characters but typically around 60 characters) and wonder what makes for faster retrieval? Or does it matter? A field defined as Varchar(255) or Text? It is unlikely this field will be used for searching and it will not be indexed. This table will be part of a web application so a lot of people will be doing queries on the table and this field will be displayed as a grid field in the browser. The user queries will only return10-100 records at a time but there will be a lot of simultaneous connections to the database. Any opinions on which is better? VarChar(255) or Text?

Re: Tighly packed table
...and because no one has been really cynical... After that query runs, then prepare for a coffee overload whilst you perform the ALTER TABLE, then get ready because if you shorten the field to (say) 12 characters/bytes the very next day, someone with a 13 character name is going to try to register! I'm wondering just how much space this 'little' exercise is going to save, either as a ratio of the size of the db, or as a ratio of HDD size?

LOAD DATA INFILE - Duplicate entry '' for key...
Hi all! I bumped in a strange problem. I dumped a help table (i.e. only text) into a file. The table contains two fields: a topic (unique) field and a content field. Then performed a LOAD DATA INFILE on the resulting file in a different database with identical structure. Everything worked just fine. Later on, after some editing on the table via PHP, everything looked ok in PHP and I dumped the table once again. Guess what? LOAD DATA INFILE now says Duplicate entry '' for key 1. The table structures continue to be identical. The original data in the second database doesn't exist anymore (this is actually needed for a setup process, so the database and table are created from scratch with the same code). The dump file looks ok - similar in every way with the original - I even searched for TAB characters and there's no TAB at the beginning of any line! What gives? Did anyone else bump into this kind of problem? Thanks in advance!
