re: ERROR 2013: Lost connection to MySQL server during query
Thanks for your help, we have installed MySQL 2.23.53a on Red Hat 8.0. The problem seems to be the version of RedHat. We have now installed the same version of MySql on RedHat 7.3 and it seems to work fine. Can you give me a confirmation of this problem?

can't find messagefile errmsg.sys
10/27/02 Your [EMAIL PROTECTED] spit me out in a very nasty manner, eventhough I DID follow your guidelines to the best of my ability and this error is about the mysql daemon not starting. I'm not exactly encouraged by this and I'm wondering how much good it is going to do me that I spent a lot of time documenting all of this for you. It is true that what I'm hoping to get is my situation fixed, but I've gone to a lot of trouble here, and judging by what's on the internet, I'm not the only one with these types of problems unresolved. I can't figure out what an unemployed student with a home network is supposed to do about this - do you have an unemployed student tech support sliding scale fee for a one time installation problem? The ironic thing about this is that I never had ANY trouble with mysql on Windows 2000! Original email below: I'm on Red Hat Linux 7.3 with Kernel 2.4.18.3 (BTW, I couldn't get the mysql bug reporting mechanism to work so this is my recourse). Background here, specific repeatable steps lower down: After several headaches trying to install MySQL 3.23 from rpm, from binaries, using root as installer, using mysql as installer, I gave up and deleted and am now trying MySQL 4.0.4 where the errors are more understandable but equally frustrating. I've lost 5 days of my life and installed and deleted (yes keeping track, and deleting my.cnf too associated files then experimenting with not deleting all the files - I've done it every way I can imagine - most recently first creating a user mysql WITH a linux login password -as well as the group - before installing mysql) and reinstalled etc. With mysql 3.23 I kept getting errors about mysql.sock. Plus lots of other errors, I wound up creating a lot of files manually, changing ownership on files making them more permissive, making links, all to no avail. Specifics: On 4.0.4 After installing, reinstalling, and reinstalling. When I attempt to start mysqld, I keep (a, consistency) getting the error message (from hostname.err) Can't find messagefile mysql-long-name-4.0.4/share/mysql/english/errmsg.sys When I checked, yes the file did indeed exist in that directory: rw_r__r__ mysql users errmsg.sys so I moved it because it wasn't reading it anyway mv errmsg.sys errmsg_old.sys Got a new error message /usr/local/mysql/libexec/mysqld doesn't exist or isn't executable. Well, at least that is understandable. And the mysqld file really didn't exist at that location. Oh, I tried to start mysql in safe mode so it would look for the most reasonable path probably switched paths because of it. I know more about this than I ever wanted to. I've spent hours on mysql.com and even more hours on Google looking up error messages. I created a symbolic link from one of the places that mysqld resides ln -s /usr/libexec/mysqld /usr/local/mysql/libexec/mysqld Trying to start the daemon after doing this gave me: Can't find messagefile /usr/local/mysql-long-name-4.0.4/share/mysql/english/errmsg.sys Aborting mysqld ended I like this better because at least it is an absolute path so I know the process is pointing to the same place I'm looking. Now I moved errmsg_old.sys back to errmsg.sys which I hoped would fix the problem. It didn't. Same error message. So I re gunzipped and untarred the original .tar.gz file and ran mysql_install_db for the 110th time. The bug repeats itself exactly. I also tried this with making the symbolic link from /mysql-long-name-4.0.4/bin/mysqld to /mysql-long-name-4.0.4/libexec/mysqld (instead of from /usr/libexec/mysqld) with the same results. Attempting to run mysql-test-run gave me errors: Can't find messagefile /usr/local/mysql-long-name-4.0.4/share/mysql/english/errmsg.sys Aborting Error executing mysqld --bootstrap Error: could not install master test DBs I really NEED to install MySQL and have it running properly from my Linux Red Hat box. Oh yeah, other error messages I got (from 3.2.3 which had a wide variety of error messages including missing my.hosts file and unable to use mysql.sock) included stuff about ELF and gcc (which of course RedHat7.3 does not have, the C++ compiler is egcs) I would appreciate any help you can give me with this. I am fairly new at Administering Linux so maybe there is something that everyone knows that is so basic that I'm missing and not finding in any documentation. If that is the case, since similar errors seem to be sprinkled all over the internet in lots of usegroups, maybe they SHOULD be documented - I haven't found any answers out there. BTW, I am unable to execute mysqladmin so mysqladmin version is out of the question. I am running the most recent beta, downloaded Friday. mysql-4.0.4-beta-pc-gnu-i686 I ftped from Virginia last, I think. If you have more specific questions for me or want me to run perl or shell scripts on my environment to give you more information I'm willing to do so. --

date_sub, must use a datetime column type?
Hello List, Is it true that the date_sub function(s) will only work on datetime column types? SELECT count(id) as id FROM messages WHERE client_id = '2' AND datetime_col date_sub(NOW(),interval 1 day) To get the above query to work, I had to change my datetime_col column from timestamp to datetime, and that breaks A LOT of formatting work I had done previously when I thought I was only going to be able to keep with a timestamp column type. Could someone suggest a replacement query for the one above, where I would not have to change my datetime column from timestamp to datetime? Alternatively, could someone suggest a Java alternative to the following that would allow me to get the HH:mm from a datetime column type? SimpleDateFormat(HH:mm).format(rs.getTime(datetime_col)) I tried playing around with rs.getDate to get HH:mm, but couldn't see the light. Specifically, (rs.getDate(datetime_col).getTime()) did not work. Anyone? It's 4:35 AM. I'm dying.

Need a little query help
I am trying to select some data from a hotel database I am putting on the web. Currently I am using two temporary tables and three queries to get the data, but I suspect it can be done in one query by a better knowledge of SQL. The tables are Hotels: ID, PostCode, ShowHotel AmenityLink: ID, HotelID, AmenityID, Value I have the postcode as $postcode and one or more amenities = 'y'; I want to find all active hotel IDs with PostCode = $postcode and having the amenityid, ignoring the amenity value as I will test for that later. SELECT Hotels.ID FROM Hotels, AmenityLink WHERE Hotels.ID = AmenityLink.HotelID AND ShowHotel = 1 AND PostCode = '$postcode' AND (AmenityLink.AmenityID = $amenityid[1] OR AmenityLink.AmenityID = $amenityid[2] ) The problem is, it is easy to test for one amenity, but I need to test that the hotel has all of the amenities. The query above returns all the hotels that have ANY of the amenities, I need the hotels having ALL of the amenties only. Thanks for any assistance.

Performance degradation over time
I have a script written in python running on Suse linux using mySQL 3.23.32. There are two tables each with an auto-increment key and one index. Table 1 has a maximinum of 1,000,000 records and table 2 has a maxminum of 20,000,000 records. The script performs a mixture of inserts, updates, deletes and selects. it has an output line every 10 seconds saying how many records have been written since the last sample. I set it running @ 6.00 last friday and performance started @ 1200 transaction per second and degraded gradually to about 12 a second. I then connected to mysql and asked for the count of both tables, 'select count(*) from table_name'. After the query, performance went up to 700/sec degrading after an hour or so the aroung 500/sec. Can anyone offer an explanation to this interesting result. Dave French.

Re: BLOB inserts vs. storing filepath
John Meyer wrote: Hi, I've got a client that I'm trying to convince to store the file path in the database rather than the file itself into the database. Is there any statistical data to show how much of a hit you take doing it as a BLOB vs. a filepath? Assuming MySQL is equally efficient to your filesystem at storing the file, and your filesystem is as efficient as MySQL at finding the file (use ReiserFS), then the issue comes down to maintainability and usability. In most cases, the files I want to store are easily accessible (NFS / SFTP / local), so machine name and/or filepath is sufficient for me and I don't have to maintain that data in the MySQL table space. On top of that, you don't have to worry about hitting maximum table sizes (in MyISAM tables) as quickly either and your files are still easily accessible from non-MySQL aware programs. -- Michael T.

How could you model Charlie Haden, Miles Davis, the Brecker brothers, and so so? Peter's right. If you want a robust model, you have to break out groups and artists. If you want a historically accurate model, you may need a junction table GroupArtists, with FKs into Groups and Artists, and a pair of date columns indicating from and to -- which could overlap, again especially in jazz.

In order to make searching easy I wished to keep these names in one table. EG: searching for artist name, whether a group or soloist you would have to search only one table. The problem arises if the person wishes to get the names of the artists in the group or an artist also performs in multiple groups. I thought a self relationship of sorts solved this but then I could not figure out how to write the query. For instance the simplest query is: show me all the groups and artists in each group, or Show me the artists names in group U2. Easy if groups and artist names were in 2 tables, however... A table B table -- idNameid grp_id art_id -- 1 Joe 1 2 1 2 U2 2 2 3 3 Mike 3 2 4 4 John -- 5 Jane --- In the above sample data, table B is a join of sorts where the A.id functions as both the B.grp_id and B.art_id. EG: B.grp_id = A.id AND B.art_id = A.id I thought I had come up with a nifty little trick (using the same id in different fields to designate a distinction ) but alas. I can only select one column to get the names of the group and artists. I thought nested selects would solve this - maybe not - but no nested selects in mysql anyway. So..can this be done with this design or must I split the artists and groups into separate tables, forcing a multiple table search? I hoped column alias would solve this but I could not make it work using them. Confused? Good...so am I!

Problem with indexed joins
Hi, I'm relatively new to MySQL, and am having trouble with the optimization of some of the queries. I have two tables (T_PERSONNE and T_DEVIS) which are supposed to be linked by a foreign key (T_PERSONNE.PERS_ID = T_DEVIS.DEV_PERS). I've put an index on the foreign key (DEV_PERS), and even on the combination of PERS_ID and DEV_PERS (this worked fine for another table with a similar structure), but when I analyse the query using EXPLAIN, the base still wants to use an ALL join on the second table.

Re: database corrupted after power switched off
Thanks. You're right, of course. Nevertheless, I think the suggestions I made should help. (Context: There was a post asking how to avoid table corruption. There were several replies suggesting UPS. I suggested that, in addition to UPS, there were two other things that could be done.) (1) Use InnoDB. Of course, you need to worry that InnoDB does a physical write when it thinks it does. My understanding is that it tries to do so, if it can, when innodb_flush_log_at_trx_commit=1. (2) If MyISAM updates are infrequent, flush tables after updates. This closes the files, which generally causes physical writes on most OS's. Of course, this doesn't help with loss of power while an update is running, but it does avoid corruption when there are no updates going on, and MyISAM is susceptible to the latter. - Original Message - From: Michael T.

RE: self relation query help
This is probably going more into db design than pure mysql issues...on the other hand if performance is at stake with these different designs. After several inputs - which I am EXTREMELY thankful for - here are some of my thoughts. The solution using Joseph's table aliases works beautifully. With that said, I also see the value in using separate tables. And from a design perspective, which I really enjoy working on, that seems the better solution given the ease of maintenance on one subject entities. However, in this case I believe the table groupmembers which is a table of all the groups and its members, with the dates they were in those groups - a point Arthur makes which is already in place - works as effectively as creating separate tables, and makes the search algorithm easier to code - at least for me! ;-) . If an artist recorded with multiple groups, their id appears in the groupmembers table associated with all groups they performed with and the dates. This seems similar to me as an example I saw regarding bowling league teams and captains. The captains were also bowlers so a self-relation was used keeping all the bowlers in one table. In large DB's, such as an Amazon, or CD now, you can only search by artist, song, album title, etc. There are no group searches. So if they are parsing out groups into another table then I would love to see the code for that 'cause they are quick! Classical searches differ given the conductor, orchestra, etc. Which makes me wonder why Jazz searches are not set up that way as well. h I have a linking table of sorts to combine artists with groups, but eliminate an additional group table. Am I missing something here that should be obvious as to a serious problem with the one table design? Yes, I'm trying to defend the one table design. hehe. Honestly I had given it up for Arthur and Pete's design until Joseph showed me the table alias method. So we can blame him! ;-) Thanks for the input and feel free to fire away with any other thoughts and suggestions. I'm new to this mysql stuff. It rocks! Franklin __ Do you Yahoo!? Y!

Delete link points outside datafile at 0 and in another two tables i get this error... Couldn't fix table with quick recovery: Found wrong number of deleted records.

using libmysqld - can't connect to remote DB as client.
Nobody answered my question, so I felt like I should ask again ... I'm using libmysqld to embed a mysql server in my C app. However, I'd also like to connect to other remote mysql databases as well, but the mysql_real_connect command doesn't seem to be working when trying to connect to a remote database in the same app as the libmysqld stuff. The connect works, but I think that it's connecting to my local database and not the remote one. Here's a little code: mysql_server_init(sizeof(server_args) / sizeof(char *), server_args, server_groups); // Here's the embedded database. This works. one = db_connect(NULL); db_do_query(one, CREATE DATABASE my_blah_database); mysql_close(one); one = db_connect(my_blah_database); db_do_query(one, create table blank (num int)); mysql_close(one); /* This must be called after all other mysql functions */ mysql_server_end(); // Here's the remote connection - it connects to the same local machine, not the remote machine. two = db_remote_connect (remote_machine,remote,remote,dbname); db_do_query(two, SHOW DATABASES); Has anyone tried this.

mysqld bringing down server
I now maintain a popular internet sports portal which runs mySQL. Last weekend, the server (x86 linux) started grinding to a halt. When I list the processes, there are many, many (much more than the number of webserver threads!) mysqld threads running at once, sitting on the CPU for long periods of time. This is new behavior, and when I restart the mysqld, this situation reliably occurs again in a minute or so. How can I debug/repair this sort of thing? I have no idea what's going on, and I've never run into this sort of problem before. Is there any way to get connections to the backend to time out? Also, the documentations makes some comment about the default settings for mysqld not being configured for high-load situations, but then fails to explain how to do this. Any suggestions? -dj - 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: database corrupted after power switched off
From: Ed Carp [EMAIL PROTECTED] is it a normal behaviour that a sql databases gets corrupted if the power of the whole system will be switched off while an application is writing to the database ? Yes. what can i do that this problem does no more appear ? Buy a UPS or shutdown the system normally. NEVER just turn off power to a computer. And note that this is NOT a MySQL problem! If the power goes off while ANY program is writing to disk, you are likely to have (at best) a corrupted file, and possibly a corrupted file system as well! If you turn off the power while writing a Microsoft Word file (for example), you will also have a corrupted file. What sets MySQL apart is that there is generally more at stake than there is with a single Word file. Small UPS systems are quite inexpensive these days. Even office-sized systems that will protect numerous computers cost no more than a single new computer. (And they last longer!) Anyone doing anything that is mission-critical for any business of any size should have a UPS capable of keeping the system up long enough to shut it down gracefully. -- SQL SQL SQL SQL SQL SQL SQL SQL : Jan Steinman -- nature Transography(TM): http://www.Bytesmiths.com : Bytesmiths -- artists' services: http://www.Bytesmiths.com/Services : Buy My Step Van! http://www.Bytesmiths.com/van - 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: mysqld bringing down server
Hi David, I've seen a similar behavior on our machine. We had someone re-write the code for a particular PHP site that was producing tons of slow queries (while the CPU was 100% idle the script would still take 15 seconds to run its queries) and the problem was (sort of) fixed. Have a constant look at mysqladmin processlist, maybe there are tons of mysql processes sitting sleeping. You can adjust the max. wait time for (interactive) connections with: In your my.cnf, under [mysqld]: set-variable= interactive_timeout=90 set-variable= wait_timeout=90 This will close sleeping connections after 90 seconds. Default is 8 days. However, this is not a real fix for your problems but might help temporary so that mysqld is not taking your server down. This only makes sense if you have sleeping processes (according to mysqladmin processlist). Active the sleep log, it will show you which queries take up too much time ( 10 secs): In your my.cnf, under [safe_mysqld]: log-slow-queries = /var/log/mysql-slow.log mysqladmin status will show you how many slow queries you got. Investigate /var/log/mysql-slow.log to find out what the query looked like. Maybe that helps... Regards Markus On Mon, 28 Oct 2002 13:46:52 -0500 David J.

Re: InnoDB and auto_increment fields
stored? Why isn't this done automatically as it is for [ISAM] tables? As for the why, I'm not a MySQL developer, but I believe the reason goes something like this: When ISAM tables were implemented, they did it the wrong way. When other table types came along, they fixed this bug and do it the right way. You seem to disagree about which is better, but I believe the above is the explanation for the switch in behavior. As for why the MyISAM/InnoDB way is right, I believe it has to do with the idea that autoincrement values are very commonly used in situations where you want not just a key that's unique in the table, but one that will never be used again. Specifically, in ISAM tables, when you delete the highest-keyed record, that key will be given out again with the next insert. Depending on how your application is written, that could lead to unpleasant race conditions that would be easily avoided by simply not reusing key values at all. --Pete sql, db - 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?

If I go to mysql directory as a root and try to start mysql over there using ./support-files/mysql.server script it produces the error: cd /usr/local/mysql [root@jnikom mysql]# ./support-files/mysql.server ./support-files/mysql.server: @HOSTNAME@: command not found /usr/local/mysql/data/.pid usage: ./support-files/mysql.server start|stop 3. To fix it I replaced the line pid_file=$datadir/`@HOSTNAME@`.pid with pid_file=$datadir/$HOSTNAME.pid and it starts to work. I still don't know how it could work for other Oses.

Connection problems
I recently installed Red Hat 7.3 on a box, and have been having difficulty connecting to my MySQL server. I can connect locally. That is, on the same machine as the server. However, if I try and connect from a remote machine with the following command: mysql -h IP_ADDRESS -p DATABASE I get the following error message: ERROR 2013: Lost connection to MySQL server during query I've poked around on the net and in the documentation, but I can't find anything that explains this. Aside from creating a database and using the GRANT ALL command on it to setup privileges, I haven't mucked with the configuration at all. I've tried reinstalling the RPMs for MySQL and still no luck.

It breaks remote access to MySQL (amongst other bad things). If you're running on Linux, your best bet (always) is to use MySQL's binaries, as they're compiled statically, so it doesn't matter what breaks on your system with respect to GLIBC, MySQL should still work. The latest binaries (in RPM) are 3.23.53a, which can be downloaded from http://www.mysql.com/ (btw, This problem has been discussed on the mailing list for quite some time, so to save time in the future, you might try the archive at lists.mysql.com or marc.theaimsgroup.com). -Mark -- For technical support contracts, visit https://order.mysql.com/?ref=mmma __ ___ ___ __ / |/ /_ __/ __/ __ \/ / Mark Matthews [EMAIL PROTECTED] / /|_/ / // /\ \/ /_/ / /__ MySQL AB, Full-Time Developer - JDBC/Java /_/ /_/\_, /___/\___\_\___/ Flossmoor (Chicago), IL USA ___/ www.mysql.com - 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?

su problems under linux.
I am having some difficulty with users using su and trying to access mysql, either through the command line (mysql) or via perl programs using DBD. Under normal circumstances users are able to use the command line tool mysql or run perl programs using DBD. They usually use $HOME/.my.cnf for password information. However if user1 #34;su#34; to user2 mysql tries to authenticate the original user (user1), not the one #34;su#34; to (user2). Both the original user (user1) and the #34;su#34; user (user2) have $HOME/.my.cnf so passwords are not needed, but the program abends saying the user tried to access mysql but didn't provide a password. The system is running: Linux 2.2.19 mysql Ver 11.15 Distrib 3.23.39, for slackware-linux-gnu (i386) Any suggestions to remedy this problem would be appreciated. Thanks, Chris. __ Do you Yahoo!?

here's my table syntax: create table Projects ( PjID int unsigned auto_increment not null primary key, PjNumber varchar(40) not null, PjName tinytext not null, PjDesc tinytext, PJEcd varchar(30), PJCost varchar(30), LastUpdate char(30) ); create table Managers ( MgrID int unsigned auto_increment primary key, MgrName varchar(40) not null, PrimaryID int unsigned not null, AlternateID int unsigned not null ); create table PjStatus ( StatID int unsigned auto_increment not null primary key, PjID int unsigned not null, Actions longtext, Status varchar(10) ); create table POCs ( PjID int unsigned not null, pmyid int unsigned not null, altid varchar(5) not null, I only have two records stored in my database currently. You'll notice the managers table has 3 id's for each manager. MGRid is the PK only reason for that. PrimaryID and Alternate ID are both for tracking purposes. A manager might be the primary manager (meaning the one ultimately responsible for the project) or he may be an alternate (backing somone else up who is the primary). Therefore, these two columns will have a one to many relationship with the POCs table. Here's what I want to do: define a query that will select * from the POCs table and display that info via a php script in a table. Simple enough right? WRONG! I know plently about php but jack about SQL. My query is as follows: select mgrname, pjname from managers, projects, pocs where pjid = 'x' and pmyid = 'x' and altid = 'x' NOW! This should give me an output like this: +--+ |__pjname|___mgrname(primary)___|___mgrname(alternate)_| | testproject testprimary1 testprimary2 Instead, what I get is the name of the project with EVERY single manager that I have loaded. Now I only have two records (or 2 projects) loaded into this database, but I have over 90 different project managers loaded (don't ask why, lost a bet on that one). So what happens is, I get the testproject name for the pjname and I get it replicated 94 different times for each and every manager that I have loaded. So it seems like every single manager is associated with this project. WTF am I doing wrong? This is going on 11 days trying to figure this out. Am I doing the joins wrong or something? Does my table design not allow me to do what I'm trying to do? Should I instead be trying to nest 3 queries in one and display the output side by side (sort of like the html talbe theory???)?? - 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: i almost hate queires, please help!!!
you have to include relations to all the tables you've selected from. select mgrname, pjname from managers, projects, pocs where pjid = 'x' and pmyid = 'x' and altid = 'x' AND POCs.PjID = PjStatus.PjID AND POCS.pmyid = Managers.PrimaryID AND POCS.altid = Managers.AlternateID i think that is how your tables should relate. play with it a little. it should work if you make sure all the tables you are selecting from have relational statements inside the query. have fun.
