RE: blob versus file
Grabbing a half-gig video segment out of any database I'm sure you're absolutely right about not putting half gig videos in a database! I was thinking more of an application like an access control system, where there might be tens of thousands of photographs of people, each a jpeg of a small number of K, or a catalogue, again with thousands of tiny photos. The experiment I did with 500,000 operating system files was to see whether smallish blobs (bits of text, in this case, which I didn't need to search or index) were better stored as disk files or in an SQL Server database.

I had a similar number of files, about 70 GByte worth on an ext2 filesystem. Moved them to a ReiserFS filesystem and found I only needed 51 GByte. And got a much faster system... The main gain of MySQL is probably that MySQL packs the data tighter together, which in the end causes fewer hard disk head movents and less data to be transferred. And if you use indexes, your directory searches are binary chops rather than linear searches. ReiserFS does that also, but at a file system level. If you need to port your application to the outside world where you don't have control over your file systems, MySQL would be the way to go for this application. If you _do_ have control over the filesystem being used and you can use ReiserFS and you don't need MySQL specific features, then I wouldn't be so sure. Just my 2 eurocents worth...

No performance issues when used as a plain vanilla model, no stability and no security issues either, only down side to it is that it is a tad bit larger ? no MyISAM bugs which would have been special to the -Max version have been reported, as far as I know.

But a filesystem is an specialized hierachical database, and I have yet to see an (more general) SQL database wins hands down in the preferred domain of the file system - of course, a reasonable implementation presumed (which ext2 IMHO is).

Incorrect replication user time

Now, when I send show processlist command to slave, this is the response: +--+-+---+--+-+--+---+--+ | Id | User| Host | db | Command | Time | State | |Info | +--+-+---+--+-+--+---+--+ |1 | system user | none | NULL | Connect | 664 | Reading master update | |NULL | | 4377 | root| localhost | biz | Query | 0| NULL | |show processlist | +--+-+---+--+-+--+---+--+ 2 rows in set (0.00 sec) The system user time used by replication always starts at 664 seconds (0 must be correct). The intervals are correct. Two seconds more without replication updates and Show processlist says: +--+-+---+--+-+--+---+--+ | Id | User| Host | db | Command | Time | State | |Info | +--+-+---+--+-+--+---+--+ |1 | system user | none | NULL | Connect | 664 | Reading master update | |NULL | | 4377 | root| localhost | biz | Query | 0| NULL | |show processlist | +--+-+---+--+-+--+---+--+ 2 rows in set (0.00 sec) Correct!

With 500.000 files in a directory where each file is subsequently accessed in a benchmark, you get quadratic access times. reiserfs uses a tree structure for directories, giving you almost linear (O(n log n)) access. It also packs tails of different files into singular blocks, saving much space as well. Question: Can the MySQL BLOB API access and transfer partial blobs. That is, if you want to do the equivalent of a file * to a BLOB table, the first 10 bytes or so of each BLOB must be read in order to guess the type of the BLOB. Is it possible to implement this efficiently using the MySQL API? More specific: Can I efficiently read the bytes x to y from any BLOB stored in a MySQL database?

Mysqld crash
Hi, I have 2 machine dual-processor Pentium III, with 1G of memory. They have the same software, same architecture, with one-way replication beetween. Versions: [root@localhost tmp]# mysql -V mysql Ver 11.18 Distrib 3.23.51, for pc-linux-gnu (i686) [root@localhost tmp]# cat /etc/redhat-release Red Hat Linux release 7.3 (Valhalla) Since i've installed mysql 3.23.51 (mysql binaries) that i'm having some problems, the worst is the slave's mysqld crashes all days. What happens: Every day, a cron job in the slave starts at 3:30AM to generate some reports. The maximum load is about 2.0. Mysqld daemon crashes and restarts itself. All queries in this cron job are done in the master. The slave only replicates... I don't understand why the slave keeps crashing. The master logs are clean, with no error at all, the reports are ok. * The log error at the slave: mysqld got signal 11; This could be because you hit a bug. It is also possible that this binary or one of the libraries it was linked agaist is corrupt, improperly built,or misconfigured. This error can also be caused by malfunctioning hardware.We will try our best to scrape up some info that will hopefully help diagnose the problem, but since we have already crashed, something is definitely wrong and this may fail key_buffer_size=335540224 record_buffer=2093056 sort_buffer=2097144 max_used_connections=1 max_connections=150 threads_connected=0 It is possible that mysqld could use up to key_buffer_size + (record_buffer + sort_buffer)*max_connections = 941474 K bytes of memory Hope that's ok, if not, decrease some variables in the equation Attempting backtrace. You can use the following information to find out where mysqld died. If you see no messages after this, something went terribly wrong... Stack range sanity check OK, backtrace follows: 0x806edf4 0x811fd28 0x81050f3 0x810410f 0x8103df9 0x80b5f04 0x809524c 0x80943b7 0x80940c3 0x808cf67 0x80760ce 0x8079a8c 0x80cfb31 0x80d1249 Stack trace seems successful - bottom reached ...

Comment-parsing bug in MySQL
Description:
Single quotes (') in comments may cause syntax errors.
How-To-Repeat:
Run this MySQL code from a file, including the comment
(running from the MySQL shell will also expose the bug,
but you will not be able to complete the command without
supplying a second quote):
/* MySQL's handling of comments is kind of flaky. */
SELECT * FROM MYTABLE;
Fix:
Work around the problem by not using the apostrophe character (')
in the comments of MySQL code.

Can this be done without UNION?
Hi all, I have a problem whith a very simple query. My problem is: it doesn't use indexes. It does full table scans instead. The only way I found to make it fast was using UNION. Can somebody please tell me, how I can make it fast (using indexes) without using UNION? My query: SELECT * FROM mytable WHERE fielda=1 OR fieldb=2 -The colums fielda and fieldb are offcourse indexed. -The table has about half a million rows. Faster is: SELECT * FROM mytable WHERE fielda=1 UNION SELECT * FROM mytable WHERE fieldb=2 Is there a way to make this fast on mysql 3.x as well? thanks in advance Gunnar - 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?

Strange problem - could be a bug?
Okay: FreeBSD 4.5-STABLE with LinuxThreads 2.2.3. and MySQL 3.23.51. Duel PIII 1Ghz with 1G of RAM. All from source. Compiled okay and came through super-smack and crash-me tests okay. But a few hours later, for no reason, MySQL decided to look at /var/tmp instead of /usr/local/mysql/var for the datadir. There is nothing in the logs to suggest why this happened. AFAIK, you have to restart mysqld to change the data dir, but the daemon was not restarted at any point. SHOW VARIABLES revealed that the datadir was still set to /usr/local/mysql/var, but SHOW DATABASES listed the contents of /var/tmp (in my case vi.recover). When I shutdown and restarted the system, it reverted to normal behaviour.

Query on large table times out
I'm trying to import a 1 GB mysql database into oracle using a perl/dbd interface written by a 3rd party software company. This is over a network, but I've pinpointed my bottleneck as being the disks attached to the target oracle db server. This process dies with a timeout on the mysql server while moving a table with 246,000 rows. It seems that some rows were added to this table while the migration was happening. The ubiquitous and uninformative error message is: 020702 19:49:25 Aborted connection 25 to db: 'test' user: 'testuser' host: `snafu' (Got an error reading communication packets) I did some poking around newsgroup archives and mysql docs yesterday and as a result tried upping the interactive_timeout parameter.

verification upon update, help, please
Does MySQL prevent updates from occurring when the values involved are the same as the database's current state. For instance, if I've got a table create table updater( id int not null primary key auto_increment, is_active int not null default 1 }; insert into updater(is_active) values (1); insert into updater(is_active) values (1); update updater set is_active = 1; Would MySQL essentially disregard this update statement b/c the values contained within the table are already 1? Now, I realize that the values wouldn't be altered, but does the dB do pre-checking and see which (if any) rows would be affected by the query, and only run the update against rows that would be changed? There seems to be some reporting that is displayed which indicates that MySQL DOES indeed to pre-checking mysql select * from updater; ++---+ | id | is_active | ++---+ | 1 | 1 | | 2 | 1 | ++---+ 2 rows in set (0.00 sec) mysql update updater set is_active = 1; Query OK, 0 rows affected (0.00 sec) Rows matched: 2 Changed: 0 Warnings: 0 mysql any thoughts? thanks, Paul _ MSN Photos is the easiest way to share and print your photos: http://photos.msn.com/support/worldwide.aspx - 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?

ADO or MySQL error ?
Hi, I have installed mySql 3.23 max for NT and i'm getting the following error, but I am not sure if it is ADO or MySQL at fault ! I need to list the tables,columns and indices of the DB and the last index access statement is failing. I'm accessing MySql via a DSN connection from within VB6. I get access the table list and the table properties but not the index info. Code attached - Command3_click fails and although it looks like an ADO error the two other commands work ? * Also I have a question regarding Discussion groups/newsgroups of MySQL users. I have written an end-user reporting tool that accesses mainframe/Unix/Vax based DBs via middle-ware and until NOW (using MySQL) uses either SQL-Server,Oracle, Sybase as the local repository to hold application info etc, as the master data would be held in Adabas/DB2/VSAM on the legacy platform. If I had access to such a group I could get info to see if any one would be interested in such a product ? Even yourselves as a marketing piece on how such an application uses MySQL as the local repository and allows users more freedom than with the Microsoft/Oracle route whilst keeping their legacy DBs as the master source. Interested ?

Creating a list from group-by values
This is not specific to MySQL (probably) but I thought this wizened community might have a definitive answer. Take this simple grouped select: SELECT Value1,Value2 FROM Table1 GROUP BY Value1,Value2 Value1 Value2 --- Joe Red Joe Blue Joe Green Jim Red Jim Green Jack Blue My end goal is really this: Value1Value2s -- Joe Red,Blue,Green Joe Red,Green Jack Blue The normal way to do this is iterate through the table using the app's code. Is this possible to do in MySQL? Using MS SQL Server or Oracle, where you can create user defined functions, I can create a function to return the list given the group-by value - but it is atrociously slow, far less efficient than doing it on the client code. Is there no native SQL way to return a list of values from within a group-by value? Seems a nice function like LIST(Value, Separator) would complement MAX(), MIN(), and so on nicely... but it seems not to exist. -- Jamie - 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?

Error on rename
Hi, Newbie here...please be kind! Sometimes when I try to execute some SQL statment MySQL throws an Error 7...(see below) For example: ALTER TABLE `categorias` RENAME `catAnimais`; And here's the error Error: 7 - Error on rename of '.\orniex\categorias.MYI' to '.\orniex\#sql2-ffc-4.MYI' (Errcode: 13) It also happens when I try to delete a Table (not always) I'm using MySQL Front to do this, but I tried from the console after stopping and starting the server and the error still occurs, so I guess it has nothing to do with MySQL Front. why does this Happen?

order by muian desc LIMIT 0, 30
The results are very disapointing :
Conceptia politica a lui Nae I

Conceptia si conceptia are loc atunci cand doua celule fuzioneaza 1

AUTO_INCREMENT with Replication
From the manual 4.10.4 Replication will be done correctly with AUTO_INCREMENT, LAST_INSERT_ID(), and TIMESTAMP values. I am somewhat fearful and curious about how this works. Say we have a master web database that gets replicated back to the office slave over the Internet. A person on the web puts in an order to the master web db, another person in the office enters a phone order, but that order goes into the slave because orders get shipped based on information in the office slave. How would I not at some point end up with replication errors because of duplicate auto_inc values? Would setting up replication as a circle help? Or would timing issues still cause a problem? (The insert on the Master beats the insert on the slave that was getting sent at the time) I am using 4.0.2 alpha so I am most concerned with how that version is affected.

Transparent Encryption [was: encrypt myisam?]
Hi users and developers! I deleted the in-reply-to header as everybody misunderstood my first mail. Please give this a thought folks, especially developers, I can help developing it if nessecary. I want to do transparent encryption. Like being able to choose an encryption scheme of a table or database when created so that the data on disk is always encrypted. I need this as my application doesn't communicate directly with the database. I do it via an application called tilde (http://tilde.tildesoftware.net), sure I can patch tilde (me and some others wrote it), but its not a good solution as I'm sure others need or at least want the same thing. There must be numerous of applications people use to store sensitive data that communicates with databases but without internal support for encryption. For examples Content Management Systems, Calendars, Business Systems, Web Shops etc.. is there anyone out there who think this idea is any good, I think its rather neccesarry. In the users interface it could be implemented as CREATE:ing the table with some extra flags, choose encryption algorithm, nums of bits etc. And when you're asking querys we'll need a new API to be able to send passphrases too. Or maybe encryption should only be turned on at the database level, not the table level, so you just have to pass an extra parameter on the mysql_real_connect()-api (the best thing is probably to create a new API, called something like mysql_connect_wparams(), taking an info-struct containing things like port, host, username, password, database, ssl-option etc..) or maybe just use the database-password as passphrase for the choosen encryption-scheme.. how strong is the PASSWORD()-funtion? is it just some crypt(3)-variant or good shit? come with some ideas! kind regards Tobias Bengtsson PS.

Re: blob versus file
Kristian, Question: Can the MySQL BLOB API access and transfer partial blobs. That is, if you want to do the equivalent of a file * to a BLOB table, the first 10 bytes or so of each BLOB must be read in order to guess the type of the BLOB. Is it possible to implement this efficiently using the MySQL API? More specific: Can I efficiently read the bytes x to y from any BLOB stored in a MySQL database? Why not just add another column, Char(3), that contains the file extension? Then you wouldn't need to read the blob data. Or you can use ENUM and define the possible blob types. By having a second column you can sort and filter on it. Another column could be the blob size (in bytes) so you know how much blob data is being stored.

RE: InnoDB or BdB
Salutations. 1: I personally use InnoDB. I think Bdb tables were the first with transactions but I don't see a lot of people talking about using them these days. Also, InnoDB is being activly developed and between sleeping, eating and coding, Heikki answers questions here! :) 2: Signed integers can have a + or an - in front of them. (The + is implied, you don't actually see it) Because that takes up a bit, it means that signed integers represent smaller numbers than unsigned. Unsigned integers can represent larger numbers. (Ok, I'm over simplifying here but work with me) There is a limit on both types as to how big of a number they can store...check the docs. =C= * * Cal Evans * The Virtual CIO * http://www.calevans.com * -Original Message- From: Wouter van Vliet [mailto:[EMAIL PROTECTED]] Sent: Wednesday, July 03, 2002 2:06 PM To: MySQL Mailinglist Subject: InnoDB or BdB Heey There Folks, Well, I hope that this message gets through finallly.

Replication errors
I have replication running successfully between two Linux boxes running 3.23.51. However, I'm getting the following error very frequently (every 30 - 60 seconds) in my slave error log: - 020703 15:41:09 Error reading packet from server: (server_errno=1159) 020703 15:42:09 Slave: Failed reading log event, reconnecting to retry, log 'db1-bin.009' position 25448 020703 15:42:09 Slave: reconnected to master '[EMAIL PROTECTED]:3306',replication resumed in log 'db1-bin.009' at position 25448 020703 15:42:39 Error reading packet from server: (server_errno=1159) 020703 15:43:39 Slave: Failed reading log event, reconnecting to retry, log 'db1-bin.009' position 25448 020703 15:43:39 Slave: reconnected to master '[EMAIL PROTECTED]:3306',replication resumed in log 'db1-bin.009' at position 25448 - Is this just a normal timeout error, because there's currently very little activity on these machines? Or is there some other problem? The slave_net_timeout value is at it's default of 3600, so I would expect to see this type of error every hour -- but maybe I misunderstand that variable. If this is just a normal timeout, is there any way to up the value or prevent these errors from being logged?

unexpected results using LEFT JOIN with more than one join_condition
From: Harald Kleiner [EMAIL PROTECTED] To: [EMAIL PROTECTED] Subject: unexpected results using LEFT JOIN with more than one join_condition Description: I use LEFT JOIN to join together two tables. And (for some 'complex' reason) I want to add additional conditions into the join_condition-part (and not in the WHERE part where it would belong to). But these additional conditions seem to be ignored just as if they weren't there. If I cut the 'ON'-part and move conditions to the 'WHERE' all goes the way it should. Changing the join method from LEFT JOIN to INNER JOIN does fix the problem - yes but alas I need a LEFT JOIN in this case. The manual says The ON conditional is any conditional of the form that may be used in a WHERE clause. So it _should_ be allowed to do the things that I do... Maybe this is all my fault - so please be patient. But in any case: Thank you very much for spending time with my problem! How-To-Repeat: I have constructed a simplified example that shows the unexpected behavior. A table called person is linked with room-table. Both have a date-typed field that holds deletion-date of the record. Now I want to get all persons with their room codes which are _not_ deleted (i.e. deleted==0). As you can see the first query uses LEFT JOIN ... ON ... and returns all four persons. (Joe gets returned even though he has a non-zero deletion-date -- that's what I don't understand) And in the second query I just replaced the first 'AND' with a 'WHERE' and voila Joe falls out (because of his non-zero deletion-date) and Fred falls out because of his null room (room.deleted gets null I think) -- that's what I expected to get. DROP DATABASE JOINTest; CREATE DATABASE JOINTest; USE JOINTest; CREATE TABLE person ( personID INT AUTO_INCREMENT NOT NULL, roomID INT, name VARCHAR(20), deleted DATE, PRIMARY KEY(personID) ); CREATE TABLE room ( roomID INT AUTO_INCREMENT NOT NULL, roomcode VARCHAR(20), deleted DATE, PRIMARY KEY(roomID) ); INSERT INTO person VALUES(NULL, 0, 'Fred', 0); INSERT INTO person VALUES(NULL, 1, 'Max', 0); INSERT INTO person VALUES(NULL, 1, 'Joe', '2002-07-01'); INSERT INTO person VALUES(NULL, 1, 'Anne', 0); INSERT INTO room VALUES(NULL, 'R001', 0); SELECT DISTINCTROW person.name, person.deleted, room.roomcode FROM person LEFT JOIN room ON person.roomID=room.roomID AND person.deleted=0 AND room.deleted=0; +--++--+ | name | deleted| roomcode | +--++--+ | Fred | -00-00 | NULL | | Max | -00-00 | R001 | | Joe | 2002-07-01 | NULL | | Anne | -00-00 | R001 | +--++--+ 4 rows in set (0.00 sec) SELECT DISTINCTROW person.name, person.deleted, room.roomcode FROM person LEFT JOIN room ON person.roomID=room.roomID WHERE person.deleted=0 AND room.deleted=0; +--++--+ | name | deleted| roomcode | +--++--+ | Max | -00-00 | R001 | | Anne | -00-00 | R001 | +--++--+ 2 rows in set (0.00 sec) Fix: Yes, I could move additional criteria into the WHERE but that would be not as beautiful and easy for me as putting it into the ON - part. And even in the manual (chapter 9.8.1, The Twin Project) such a join is used. So it _should_ work.

Re: AUTO_INCREMENT with Replication

I am somewhat fearful and curious about how this works. Say we have a master web database that gets replicated back to the office slave over the Internet. A person on the web puts in an order to the master web db, another person in the office enters a phone order, but that order goes into the slave because orders get shipped based on information in the office slave. How would I not at some point end up with replication errors because of duplicate auto_inc values? Would setting up replication as a circle help? Or would timing issues still cause a problem? (The insert on the Master beats the insert on the slave that was getting sent at the time) I am using 4.0.2 alpha so I am most concerned with how that version is affected. You're asking for trouble. :-) AUTO_INCREMENTS are not safe for use in a mutli-master environment.

How to On DELETE CASCADE
Hello, I'm quite new in MySQL and PHP, so I guess my question is stupide. Sorry for that but I really need the solution... I have 2 tables table Client : --- |ClientID | ClientName| --- |1| Eric | |2| Mark | |3| Simon | --- and table Command : --- | CommandID | ClentID | Price | --- | 2 |1| 32 | | 1 |1| 12 | | 3 |2| 38 | | 4 |2| 65 | | 5 |3| 81 | --- The primary Keys are ClientID on table Client and CommandID on table Command. I'm looking for a way to be sure that when deleting an entry in Client table, all the corresponding entries in Command table are deleted without sending a specific request for that. It seems that in SQL a froreign key is the solution but the MySQL documentation says that foreign keys aren't implemented in MySQL, so how to solve this elementary issue ?

This is really transperant, no needs to make changes in the client :) Or maybe encryption should only be turned on at the database level, not the table level, so you just have to pass an extra parameter on the mysql_real_connect()-api (the best thing is probably to create a new API, called something like mysql_connect_wparams(), taking an info-struct containing things like port, host, username, password, database, ssl-option etc..) or maybe just use the database-password as passphrase for the choosen encryption-scheme.. how strong is the PASSWORD()-funtion? is it just some crypt(3)-variant or good shit? come with some ideas! What about different users (hopefully with different passwords) using the same database? In what way, other than protecting the database ondisk-files from beeing stolen and read, will your proposed change increase the security? If you are able to steal the ondisk-files you are also able to ptrace mysqld and aquire the data that way. To me it seems as a good way of making oneself just feel secure when infact it almost doesn't buy you anything. PS.

Re: Strange problem - could be a bug?
In the last episode (Jul 03), Mike Hall said: FreeBSD 4.5-STABLE with LinuxThreads 2.2.3. and MySQL 3.23.51. Duel PIII 1Ghz with 1G of RAM. All from source. Compiled okay and came through super-smack and crash-me tests okay. But a few hours later, for no reason, MySQL decided to look at /var/tmp instead of /usr/local/mysql/var for the datadir. There is nothing in the logs to suggest why this happened. AFAIK, you have to restart mysqld to change the data dir, but the daemon was not restarted at any point. SHOW VARIABLES revealed that the datadir was still set to /usr/local/mysql/var, but SHOW DATABASES listed the contents of /var/tmp (in my case vi.recover). When I shutdown and restarted the system, it reverted to normal behaviour. Anyone have any idea what is going on? Weeird. You don't happen to have written a UDF that changes directories, do you? From a quick scan of the source, mysql chdir()'s to the datadir once on startup and uses relative paths to access tables. This means that any chdir() call made while mysql is running will screw up table access from that point on. -- 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: AUTO_INCREMENT with Replication
if you set it up so that the slaves occasionally update the master, you can get around the problem as follows. For the *primary* table(s), when you update the master, get the data for 1 row to update from the slave. When you insert this row into the master, remove the auto_increment field from the list of set values. Then, when the row is inserted, it is assigned a new auto_increment value. This could be a problem if the value you just dropped is meaningful, like an invoice # for instance, and not just a (meaningless) unique id. If you have *child* tables that use that key like a foreign key, you'll need to do some manipulation on the rows from those child tables so that they still relate properly. I have successfully implemented things similar to this for an order /billing system where orders could come from on-line, phone orders, etc. It is a bit of work though, and depending on the app, there may be some things you can't do quite right.

Re: InnoDB or BdB
Hello, My perception of the InnoDB vs BDB question is that although the BDB is very impressive and long standing, it does not get the same level of attention that InnoDB seems to get from the good folks at MySQL AB. If I am not mistaken, BDB does not yet offer foreign key support. I have chosen InnoDB instead of BDB and have not been disappointed so far. A signed interger is one that can accept both positive and negative values. Because storing the sign of a number uses one bit, and unsigned interger can hold a larger positve value than an unsigned integer. For example, given a 16 bit interger, the maximum value for an unsigned is 2^16, and 2^15 for the signed version.

MYD files deleted
Hello All, I'm using mysql version 3.23.47 as a database in an embedded device. In the startup scripts for the database I have it run : myisamchk -o -s /usr/local/var/data/*/*.MYI (to fix any possible problems) with safe_mysqld --datadir=/usr/local/var/data (to start the database) On one occasion, during testing I came across an issue where if I poweroff the machine while the database is starting it seems to DELETE many of the MYD files, including host.MYD, user.MYD, along with data MYD files. Of course this makes the database dead. Its not clear to me if its the myisamchk, safe_mysqld, or something else that is actually killing these files. I'm not concerned with retrieving this data, but I do want to find exactly what, and why this is happening and implement a fix. I should note that I am able to re-create the problem if the timing is correct. A possible low tech solution will include copying the MYD files (most of my data is stored in innodb and was not harmed) before starting the database and restoring them from the backup if they are missing. Of course, I would prefer a more proper solution. I'd appreciate knowing if anyone else has had this problem and what version you're using, even if a solution hasn't been found.

Re: Affecting weighting of fulltext indices
I'm working on a search interface in MySQL for a series of items that
have titles and descriptions. I'd like to weight the results so that
matches in the title count for more than matches in the description.
Is there a recommended way of doing this?
So far, I've come up with three ways, two of which seem to work.
The first and most straightforward is to create a keywords table,
and then list the word multiple times depending on where it was listed
to give it extra weight. For example, if the title is Children and
Dogs and the description is Boys and girls take their pets for
walks, I might put in:
children children dogs dogs boys girls take their pets walks
to give the words that appeared in the title, children and dogs,
twice the weight of the other words.
The second is to list a column multiple times when creating the
index. For example:
create fulltext index test
on TxKeywords
(Title,Title,Description);
seems to have roughly the desired effect, but I don't exactly
understand what it's doing, and I don't know if this is supported
behavior, or if might go away in a future version.
The third is to create multiple fulltext indices, and multiply the
MATCH...AGAINST number against a multiplier. For example:
select *,
match(Title) against('children') * 2 +
match(Description) against ('children')
as score
from
TxKeywords
order by
(score)
limit 10
This is extremely slow---on a few thousand rows, it takes several
minutes at least, which just won't work for an interactive
application.
Has anybody done anything like this, and would they be willing to
share their experiences? Am I missing something obvious? Any way to
speed up the third method (which seems to be the most flexible)? Can
I count on the second method being supported in future releases?
Thanks for any tips,
-ScottG.

Growing memory usage/processes
Hello all, I have mysql running on a 2.4.18 kernel: /usr/libexec/mysqld Ver 3.23.49 for redhat-linux-gnu on i386 and note that one started about 4 processes (threads?) began to handle the various signal/table tasks and such. After several random queries the process list grows accordingly. After a couple hours all processes which showed consumption of about 8MB of memory initially are now 25MB each and growing as queries are received. My question is...Why if these are threads does it require each thread to utilize so much memory? 4 threads using 10MB each is ok, 10 threads using 10MB each is ok. 20 threads using 25MB each is too much. When I shutdown MySQL available memory increases according to the number of threads * size previously in use. Is this a problem or a feature? Is there a way to limit mysqld to only a certain number of maximum threads and a maximum size of memory always? I don't really like seeing this runaway with all my memory. On the other hand, CPU load is incredibly low. Inserting about 1.5 million records never hit more than about 30% load. The machine is a dual P3 1000Mhz with 1GB of RAM. Any ideas?
