InnoDB issues - tables not found
Hi,
Newbie here, so please be kind...
I decided to try out the foreign keys (REFERENCES tabel(column) in CREATE
TABLE) and I hit two problems. Maybe it's my clumsiness with search
specification, but I couldn't find answers in the archive. Oh, I tried it
on InnoDB tables created just for this test. So here goes:
First problem: SHOW CREATE does _not_ use the same syntax I did when
creating tables - it omits REFERENCES... completely. This is not a big
deal, I can just add those in the scripts if I need them, but it is
somewhat worrisome;
Second problem - and this is a big one - after I looked around in those
tables, inserting, selecting and updating data, I disconnected from the DB,
disconnected from the server and shut down the client. Until then I _could_
see the table structures, the fact they were InnoDB type, column
definitions, and so on. I did also see free space and so on. When I came
back after dinner and connected back... no such luck. Any attempt to get
any rows out (like SELECT * FROM `table_name`) gives me:
[FLOW11 as tomek] ERROR 1016: Can't open file: 'table_name.InnoDB'. (errno: 1)
I can't see structure, number of rows, free space, table type, size,
nothing. Logged out and in using different (sufficiently privileged) names
- no cigar. Looked through the hostname.err log - nothing there, as well.
Disconnected the client, shut down the MySQL - nothing seems wrong. It
started back without complaint as well - but I still can't see my tables...
I checked mysql database -everything is working as expected, things show up...
In a way I hope it is a FAQ, in which case I would appreciate a gentle
nudge. In case it's not, though, Is there something glaring I did/didn't do?
MySQL is 4.0.1-alpha-log on Linux 2.2.17 installed from RPM downloaded from
MySQL site. Here is how I created one of the tables in question (in a new
database):
CREATE TABLE `ALBUM` (

`Title` varchar(255) binary default NULL,
`Released` date default NULL,
`Billing` int(11) REFERENCES PERFORMER(Ix),

RE: LOAD DATA INFILE and how to ignore garbage lines at end ofload file?

Also turn feedback off in Oracle so you don't get all the headers etc... -Original Message- From: Paul DuBois [mailto:[EMAIL PROTECTED]] Sent: 04 March 2002 16:33 To: Richard Bolen; MySQL Mailing List (E-mail) Subject: Re: LOAD DATA INFILE and how to ignore garbage lines at end ofload file? At 10:58 -0500 3/4/02, Richard Bolen wrote: I'm exporting data from Oracle and importing it into MySQL. The problem is Oracle puts garbage lines at the end of it's output files. As you've noted, the problem is Oracle. If you're using Unix, you could use tail to see how many of these lines there are and wc to count the total number of lines in the file. With that information, you can construct the proper value of n and use head -n to get only the initial part of the file that contains the non-garbage lines. Or you could reverse the order of the lines in the file (expensive?) and then use IGNORE n LINES in your LOAD DATA statement to ignore the first n lines. Better if you can get Oracle just to suppress these lines in the first place. Perhaps someone else will have a suggestion how to do that. Lines like 300 rows selected and input truncated to 9 chars as well as empty lines. When MySQL loads these files, I'm getting rows inserted for the empty lines at the end of these files. Can I get MySQL to ignore empty lines at the end of these files? or if anyone has Oracle experience can I get it to suppress the output of these line?

That would seem to account for me seeing a tables list, but nothing about them. Obviously, the .frm files did exist. Couldn't drop the tables or the database (Unknown table ...,...,...). Let me repeat: everything was just fine until I quit mysql. When I logged back in - with the same command, I use ksh and 'set -o vi' - that's when the issues started. I got out of this trouble by shutting down the server, manually removing all InnoDB files (including .frm), then starting it again - which created the IDB files. I then used my script to create database and all the tables. And everything was fine until I logged out. I now logged back in and everything is still OK: I can desc tables, and so on. Just one issue: when I do SHOW CREATE ..., it still doesn't show any REFERENCES ... that I had when I created the tables. Either I'm exceptionally thick, or the docs really say that InnoDB has the capability to use the foreign keys... I took special care to reference only tables that already existed, in case it's a concern. Any idea? Also about how long will the tables stay healthy?

Japanese shift-JIS messages
Didn't see anything on this specific question in a quick search of the database. If I just missed it, I apologize. What I have in mind is being able to read the Japanese error messages on an MSWindows box. So I wanted to make a mysql\share\japanese_sjis directory and save the two errmsg files in it in shift-jis. I had no problems loading errmsg.txt into a text editor as euc and saving as shift-jis. But errmsg.sys is not text. Just for fun, I tried using my text editor to filter that, too, but mysql of course refuses to start up with that specified in my my.ini file. Maybe I could re-compile something? Or run a filter on something? If this might be possible, I'd appreciate a pointer in the right direction.

That's easy enough but I also want to include all results where the record field (surname) matches the first part of the fields - in effect a BETWEEN query incorporating the LIKE function. For example select * from consumers surname BETWEEN '$surname_from' AND '$surname_to' assume $surname_from = A and $surname_to = B would only return results where the surname is A or greater but less than B, but I would like to include all records where records also start with B. For example it would return A Allan Anderson Appleby B But I want it to return A Allan Anderson Appleby B Black Brown Butterworth Has anyone any ideas?

Re: extra max() function possibly very useful?
Hi!

Richard Because that wouldn't give the correct results.
Richard I want the top 5 rows for EACH id.
Richard A short example would be,
Richard mytable:
Richard IdValHits
Richard 1 a 10
Richard 1 b 15
Richard 1 c 17
Richard 2 q 200
Richard 2 r 205
Richard 2 s 101
Richard 2 t 50
Richard 3 zz 10
Richard 3 yy 20
Richard 3 xx 30
Richard 3 ww 40
Richard 3 uu 50
Richard select max(2,hits) from mytable
Richard Id
Richard 1 b 15
Richard 1 c 17
Richard 2 q 200
Richard 2 r 205
Richard 3 ww 40
Richard 3 uu 50
Richard This is the top two rows for EACH id...
Richard without this functionality i have to do
Richard select distinct cid from mytable;
Richard foreach(cid) {
Richard select * from mytable where cid='$cid' order by hits desc limit 2;
Richard }
You may be able to use something like the following (not tested) trick
to do this:
SET @b=0;
SELECT *,(@a:= IF(@b=id,@a+1,1)) as cnt, @b:=id from mytable order by
id having cnt5;

select * from consumers surname BETWEEN '$surname_from' AND '$surname_to'
assume $surname_from = A and $surname_to = B
would only return results where the surname is A or greater but
less than B, but I would like to include all records where records
also start with B.
Append a high ascii value to the $surname_to, like '{', so that your query
will be:
select * from consumers surname BETWEEN 'A' AND 'B{'

So if I did something like

select * from consumers surname BETWEEN '$surname_from' AND '$temp'
it should do the trick?

Re: SQL_BUFFER_RESULT and SQL_CALC_FOUND_ROWS in same SELECT broken
[EMAIL PROTECTED] writes:
Description:
*** against BK as of set 1.1144 ***
It appears that putting SQL_BUFFER_RESULT and SQL_CALC_FOUND_ROWS
in the same SELECT statement is a really bad idea!
SELECT FOUND_ROWS() after SELECT SQL_BUFFER_RESULT SQL_CALC_FOUND_ROWS
either returns a huge number (too big) or zero.
Removing SQL_BUFFER_RESULT makes FOUND_ROWS() return the correct answer.
How-To-Repeat:
mysql SELECT SQL_BUFFER_RESULT SQL_CALC_FOUND_ROWS * FROM Downloads WHERE (match
(Name) against ('+fokker' in boolean mode) or match (Description) against
('+fokker' in boolean mode)) ORDER BY Name LIMIT 0, 10;

Why v3.23.49 does not build on RedHat 6.2 ?????

Bug with multi-table DELETE
Hello, I noticed a bug today in multi-table delete which corrupts my tables and indices. In the 4.0.2 changelog in the online-manual I saw a reference to a bugfix for multi-table deletes, but since I can't yet download a binary of 4.0.2 for windows I can't yet check if this is the fix for 'my' bug. I haven't yet made a comprehensive testcase for the bug, but here's the query: DELETE document_headers FROM document_headers, document_contents WHERE document_headers.did = document_contents.did AND document_headers.dcid = document_contents.dcid AND document_contents.did = %(did)s AND document_contents.version = %(version)s The error is: ERROR 1034: Incorrect key file for table: 'document_headers'. Try to repair it Before the delete-statement the table works; after the delete it needs to be repaired. After I repair it and retry the query, the same error returns. The error seems to occurs only when there actually are rows to delete; when there's nothing to delete there's no error. In attempting to repair the table I got the following messages: C:\mysql\data\linksdbmyisamchk document_headers Checking MyISAM file: document_headers Data records: 11 Deleted blocks: 0 myisamchk: warning: Table is marked as crashed myisamchk: warning: 1 clients is using or hasn't closed the table properly - check file-size - check key delete-chain - check record delete-chain - check index reference - check data record references index: 1 myisamchk: error: Found 10 keys of 11 - check record links myisamchk: error: Keypointers and record positions doesn't match MyISAM-table 'document_headers' is corrupted Fix it using switch -r or -o C:\mysql\data\linksdbmyisamchk -r document_headers - recovering (with sort) MyISAM-table 'document_headers' Data records: 11 - Fixing index 1 - Fixing index 2 myisamchk: Error on delete of 'document_headers.MYD' (Errcode: 13) myisamchk: error: 13 when fixing table MyISAM-table 'document_headers' is not fixed because of errors Try fixing it by using the --safe-recover (-o) or the --force (-f) option C:\mysql\data\linksdbmyisamchk -o document_headers - recovering (with keycache) MyISAM-table 'document_headers' Data records: 11 myisamchk: error: Can't create new tempfile: 'document_headers.TMD' MyISAM-table 'document_headers' is not fixed because of errors Try fixing it by using the --safe-recover (-o) or the --force (-f) option C:\mysql\data\linksdbmyisamchk -r document_headers - recovering (with sort) MyISAM-table 'document_headers' Data records: 11 myisamchk: error: Can't create new tempfile: 'document_headers.TMD' MyISAM-table 'document_headers' is not fixed because of errors Try fixing it by using the --safe-recover (-o) or the --force (-f) option C:\mysql\data\linksdbmyisamchk -o document_headers - recovering (with keycache) MyISAM-table 'document_headers' Data records: 11 myisamchk: error: Can't create new tempfile: 'document_headers.TMD' MyISAM-table 'document_headers' is not fixed because of errors Try fixing it by using the --safe-recover (-o) or the --force (-f) option C:\mysql\data\linksdbmyisamchk -f document_headers Checking MyISAM file: document_headers Data records: 11 Deleted blocks: 0 myisamchk: warning: Table is marked as crashed and last repair failed - check file-size - check key delete-chain - check record delete-chain - check index reference - check data record references index: 1 - check data record references index: 2 - check record links - recovering (with sort) MyISAM-table 'document_headers' Data records: 11 - Fixing index 1 - Fixing index 2 (The %(did)s and %(version)s things are python string-interpolations, similar to %s in c printf. The python MySQLdb library fills in the proper values. When I run the query in the mysql-client with proper values filled in it gives the same error.) Does this ring a bell? Is this the same problem as which is fixed in 4.0.2? Or do you want me to submit more data on this problem?

Proxy server problems
Hi I have recently had some problems with web forms not updating the website ( use PHP and the insert page should first enter the form data into a table and then update the status field in a second table correlating to the entry just made), hoever, only the first sql seemed to go through and the 2nd table never got the updated status field. It bothered me as when I test the system it worked 100%, yet some customers complained about the fact that their entries are not registered. Then I noticed that one of them had a proxy server, and it started me thinking that that could be the possible problem. So, my question is; can an outdated proxy wreak havoc with my mysql/php pages, and if so, is there a way that I can force a webpage NOT to go through a proxy? The solution will have to be software and server side based as I cannot rely on the cooperation of the end user for a solution. I know the solution probably has more to do with PHP, but I guess the PHP guru's will frequent this list as well??? - 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?

[AUTH] MySQL authentication using LDAP.
Hello all, I have a weird request. Having lots of servers (with many MySQL ones), I try to centralize most of all authentication processes by using LDAP. This is possible with Apache, ProFTPd and such but I was wondering if we could do this with MySQL. I know this is special because this is generaly the contrary we want : being able to authenticate thru a MySQL server. I dont really know how this could be done. I just want MySQL to send the login and password to an LDAP server, this one responding 'yes' or 'no'. Maybe it could be possible/better to export all the mysql database... I even thought of a MySQL pam module which could permit /etc/passwd to be the authentication source. I could reach my needs by next using nsswitch-ldap. All suggestions/ideas are welcomed even if you find this idea completely stupid (which is probably true). Thanx !

RE: storing files in mySQL
This is how we did it with PHP Remove the mysql packet size limitation. By default, mysql only accepts packets that are smaller than 1 MB. You have to restart your database with some parameters, which will remove the limitations. /usr/local/bin/safe_mysqld -O key_buffer=16M -O table_cache=128 -O sort_buffer=4M -O record_buffer=1M -O max_allowed_packet=24M If you are using Unix, check out your init-tree and change the corresponding startup file.

Re: Why v3.23.49 does not build on RedHat 6.2 ?????
hi, the source rpm for mysql 3.23.49 contains build instructions for gnu compilers 2.95 or newer. redhat 6.2 comes with a compiler that cannot handle the permissive flag (i think its ecgs-2.91). therefore the build fails. one solution could be to install a more recent compiler version and try to recompile again. be aware that actual rpm's will be created by rpm version 4, whereas redhat 6.2 has rpm version 3 installed which possibly cannot handle version-4-rpm's (although there had been a rpm-3 version which could _read_ rpm-4 packages - i think it was 3.0.5.) besides that, there may be glibc issues. redhat 6.2 has glibc 2.1.3 installed. i don't know if actual gcc or mysql versions work ok if compiled against this 'old' glibc. afaik, redhat does _not_ recommend to update the glibc version installed... if you dont have very specific reasons to stick with redhat 6.2 in my opinion it could be simpler just to install a later redhat version... not sure if this really helps... bye michael Gabriele Carioli wrote: Hi everybody...

MS-Word and PDF files are essentially binary files (very much like images). I suggest leaving them as they are in a separate directory. These MS-Word and PDF files may be converted to plain ASCII using filters (mswordview, pdftotext). The resulting ASCII versions are then loaded into a table with one column of type TEXT along with a VARCHAR pointer to the filename. Create a fulltext index on the TEXT field. A fulltext search for some keywords will return a sorted list of filenames. These files can be returned to the client. This scenario works well for me on a collection of some 15'000 HTML documents (I used w3m as a filter to convert to ASCII). All conversions are done with a simple shell script calling the filters.

The connection overhead in MySQL is minimal. Has anyone created a table showing the connection times of the various databases? Like MySQL, PostgreSQL, Oracle, Interbase etc.? Then you could say Oracle was 4xMySQL, or 3xInterbase etc.. I think it would give developers a better understanding whether they need persistent connections or not.

RE: how can I use 'C' programs accessing a MySql
The best book for c programming I found is the O'Reilly book, MySQL mSQL
. It has a good example of using the C API and even builds some simple C++
classes.
The book, MySQL by Paul DuBois is the best overall MySQL book I found.
Plus, Paul is a regular responder to this list, so I would buy his book,
too.
As far as creating tables (or just about anything else) the thing to
remember that about all the C API does is pass the command you want to the
SQL interpreter and then execute your command.
So, if you want to create a table, you would pass a CREATE statement into
mysql_query (or mysql_real_query) EXACTLY like you would have entered it
into the mysql client.
These is lots is some contributed software out there for the C/C++ API, but
they all have problems when it comes to inserting and updating records. The
issues is in understanding exactly how MySQL returns stuff in the result
set.
I have attached some C++ classes (and a test program) to this document that
should get you started. They deal with the type saftey issue, updating
different data types and different size strings, etc.
You will also need to go to boost.org and get some code to install something
called lexical_cast, too.
Zip file removed to post to list. Email me if you want the classes
Hello MySQL employees -
If you want to post this zip file on your contributed software section, you
have my permission to do so. These would have saved me months of effort and
I know someone else can use them, too.

My suspicion is that my problem might be in zlib. The zlib docs say that it is thread-safe, so maybe I am compiling it incorrectly. I asked a friend, who felt absolutely positive that he had a thread-safe zlib, to try this code. His results differed from mine -- the mysqld did not crash, but he produced dramatic table corruption. This code is just not that complex, and it surprises me that it has been such a pain. I really need this functionality and hope that maybe someone else on this list, with more experience in this area, either could use this functionality also (and can spend some time finding the problem), or can just look at the code for a minute and, by experience, just see the problem. ...and please email a patch to me! :) The code is attached as an Unix ASCII text file, mysqld_udf_zlib.cc.

C API BLOB type field lengths returned
Howdy - I am using the C API and am returning a result set from a table with a BLOB type item in it. When I populate the BLOB fields initially (with all the same data) the length is returned properly when I issue SELECT * FROM table and decode the result set column metadata. Meaning, that if I put , This Blob's for you! in the column, the value of MYSQL_FIELDS.length = 65535 (max of BLOB type) and MYSQL_FIELDS.max_length = 21. When I update a few rows and put, That's OK man, but you still can't have my BLOB! in a few columns, the values for the length of the fields are returned funny, or at least, I don't understand why they are returning they way they are. Meaning the value of the new column length are all set to MYSQL_FIELDS.length = 65535 (again, max of BLOB type) and MYSQL_FIELDS.max_length = 49. Problem is, this is even on the unchaged rows! Yuk! A little experimentation showed that if I select on only unchanged rows, the length is returned as 21. But, if the result set has one of the changed rows in it, the length of all blob fields is returned as 49, when (at least to me) it should be 21 or 49. In other words, it returns as the BLOB max_length value the value of the longest blob in the result set, NOT the max_length of each row. I inserted (and updated) some records in the table with BLOB contents It's all about the BLOB and I see the same result. It returns not the length of the BLOB for the row, but the length of the longest BLOB field in the result set. We are running MySQL 3.23.46-Max on RedHat 7.2 Question: 1) How do I get the actual length of the BLOB column in the row, without storing a separate column to maintain BLOB length manually?

RE: Slient install - Win32 Mysql
Hi, I tried it too, got the same result. I looked into the setup.iss file that setup -r created, and found these lines that looked different from the others: [SetupType-0] Result=301 szDir= The SdAskDestPath dialogs has: [SdAskDestPath-0] szDir=C:\mysql Result=1 So I thought I'd give it a try and change the SetupType section like this: [SetupType-0] Result=1 szDir=C:\mysql And now it works!

With the IS project source in hand it would be a piece of cake to handle this situation. BTW this silent setup thing is working with another software (I tryed it with J2RE 1.4.0 - I had to collect the exracted stuff from the temp directory during installation but then it worked all right). Maybe there's a bug in the InstallShield version used (it is an old 5.x version). Maybe there's a bug in the IS project for MySql. Maybe I'm doing something wrong.

Re: storing files in mySQL
On Tuesday 05 March 2002 10:05, Thomas Spahni wrote: There are some good reasons for wanting to store data directly in the database, sometimes. For instance I built an application recently that used blobs. The reason is simplicity and security. In a web application it is nice to just dump the files into a directory and point to them, but consider that if you are building NOTHING but a database server, you don't want to have to support and manage security for another protocol, like ftp or http. In addition in my case it would have made the client code much more complicated since the client could already deal with an ODBC data source. I would have had to code in an entire new piece of functionality to deal with the ftp or http protocol, then figure out how to engineer it so the client code would automatically go and get the data, etc. Plus now I can't just manage data security with SQL GRANT instructions. On top of that huge directories are very slow in most file systems. We had over 24 million records! That would mean that some elaborate scheme would have to be developed, like MD5 hash the filename and walk a series of directory levels down based on characters in the hash, etc. Since data is getting added and removed constantly there would then have to be a way to manage that tree to keep it from getting unbalanced etc. In the final analysis this would have been pretty close to the equivalent of building our own b-tree index! Given that database already have highly optimized indexes, it seemed more sensible to use the existing functionality of blobs and indexes. I think what all this points out is that MySQL developers might want to consider how to better support this type of application in the future. Currently HUGE tables of large blobs ARE very awkward. Our blob tables are terabytes in size, and the corruption of one record can force the tape restore from lower regions... Not to mention the horrors of backing the thing up, or any operation that mysql tries to perform by copying the table (of which there are several I believe). Maybe a special table handler module could be written that would cater to the needs of this type of application, plus a few special tools for doing repairs and such. Just an idea :o). On Mon, 4 Mar 2002, Dang Nguyen wrote: I'd like to know how to load files, such as MS-Word documents or PDF documents, in a mySQL database. I've setup a blob type in a table, but where do I go from there? The purpose of this is to store files uploaded from a web page and processed with Java servlets. Then, the files should be retrievable (displayed or downloaded) back to a client browser. My environment: Apache Web server 1.3.x on Solaris 2.8 with Java servlets environment. MS-Word and PDF files are essentially binary files (very much like images). I suggest leaving them as they are in a separate directory. These MS-Word and PDF files may be converted to plain ASCII using filters (mswordview, pdftotext). The resulting ASCII versions are then loaded into a table with one column of type TEXT along with a VARCHAR pointer to the filename. Create a fulltext index on the TEXT field. A fulltext search for some keywords will return a sorted list of filenames. These files can be returned to the client. This scenario works well for me on a collection of some 15'000 HTML documents (I used w3m as a filter to convert to ASCII). All conversions are done with a simple shell script calling the filters.

There _may_ be. But, it seems the datadir path is respected (works) fine (although I didn't try a path name with spaces) Miguel, Thanks again for your time. Thanks to your persistance I have MySQL installed with the data where I want it. :) -Ryan [Chop] I need to confess you, that until now I didn't have in my mind to use a directory name like __work.

With the changes above, I ran the server without any problem. Regards, Miguel I get the same error. Note: I did copy the c:\mysql\data tree (with all files to the non-standard location and modified the my.ini). Anyway, I went back to the original machine and got it working by pointing back to the standard c:\mysql\data dir for all files I don't like this but, it works Thanks Anyway For Your Response, -Ryan [Chop] - 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?

No. That is the nature of relational databases. Is this because the index cache in ram may not be loaded in order ? No, it's because relational engines consider a bunch of rows as a set, and order is not a property that sets have. Thus, such engines make no guarantee about the order in which they'll return a set, unless you specify an ORDER BY clause to provide sorting instructions. You might want to consider adding an AUTO_INCREMENT column, then inserting in the order you want them back. Then you can retrieve in that order by using an ORDER BY on the AUTO_INCREMENT column. My rank column is the order that I want them back in. Then use it for sorting. Won't that give you the result you want? Would you agree that sorting small row sets on the client with say PHP is more efficient than asking a busy MySQL server with many clients to do ORDER BY so that FILESORT or TEMPORARY can be avoided ? That's subject to empirical test. :-) In general, the MySQL server's built to be able to sort efficiently, so you may as well let it do the sorting. Sorting on the client may not gain you anything if the web server and the MySQL server are both running on the same host, which is common.

Re: storing files in mySQL
...and so I'm tempted for the third time to bring up my issue which has to date resulted in no response: BLOB columns causing various, seemingly random out of memory errors on FreeBSD. Is this problem too low-level for the list? I see plenty of responses to questions about simple queries, even PHP code examples -- but it seems that more serious questions warrant no reply. If nobody can help me, could someone at least point me in the right direction? I've exhausted all my search options, from list archives to bug reports (turns out mysqlbug just sends an e-mail to this list, and I've provided most of that information in my e-mails anyway), and found no references to this issue. For consistency, I'll quote my second e-mail: I'm having an issue with BLOB columns (MEDIUMBLOB and LONGBLOB, more specifically) in a table that's intended to store files (with filename, content-type and length columns). Generally, the problem seems to be that MySQL thinks that it's out of memory when dealing with arbirarily large values, either during an attempted INSERT/UPDATE (using LOAD_FILE() or the contents of the file as a string) or during a mysqldump. The problem has manifested on 2 x86/FreeBSD development boxes running the ports installation of 3.23.46, as well as an OSX box running 3.23.47. The exact same operations succeed on our production server, a Sparc/Solaris box running 3.23.36. The my.cnf's are identical on all 3 machines: a copy of the my-large.cnf with a modified max_allowed_packet value of '16M' (which should suit a query that INSERT's a file at least 7MB in size, with escaped characters, etc.). The specific errors encountered are: - when attempting an INSERT INTO binaries (contents) VALUES ([str]), where [str] is the contents of a file over ~2MB, the INSERT fails with Out of memory: (xxx bytes needed). Subsequent attempts *sometimes* result in the MySQL server has gone away error. The same errors occur when replacing [str] with LOAD_FILE([filename]). - when attempting to dump a database containing values of LONGBLOB columns over ~1MB, mysqldump fails with the same Out of memory error above. - when attempting to feed a dump into a database using the mysql DB dump.sql method (or source'ing it from the SQL prompt), values in the same range cause mysql to die with the error MySQL server has gone away. I should also mention that the errors are pretty erratic: the same operation often yields different errors on each attempt. A recent mysqldump succeeded on one FreeBSD box, but the attempt to restore it on the other one failed (MySQL server has gone away). Several times, attempts to INSERT large values have resulted in corrupt tables, or NULL values without any error. Has anyone else experienced any of these symptoms? Our production server (which routinely handles files in excess of 5MB) hasn't exhibited this issue yet, and it's running a practically ancient version of MySQL. An installation of the same version (3.23.36) on one of the FreeBSD boxes showed no change. We've checked the physical memory and df on all 3 boxes that we've experienced the problems, and none of them even come close to being out of memory or disk space. We even checked safe_mysqld to see if it calls limit or ulimit... which it doesn't. I'm totally stumped. There are some good reasons for wanting to store data directly in the database, sometimes. I'd like to think so, too... but this problem is keeping us from storing anything larger than 2MB in a column that's supposed to be able to store 16MB worth of data. If we can't make this work, then we'll be forced to abandon MySQL, and I would really hate to do that! cheers, -- shawn allen | [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: Default record order...
Hi. I guess your problem comes from the fact that SQL has no concept of internal order. If you do not specify an ORDER BY clause, the order or records returned is undefined, i.e. random. Of course, MySQL has some kind of internal order depending on many factors, but you may not rely on it. And neither you may rely on the fact that a PRIMARY KEY influences the internal order. You have to use an ORDER BY clause if you want to get a sorted result (of course, you want a key to speed up the ORDER BY clause). As said, the (sorting) behaviour without ORDER BY is undefined according to the specification and may change without notice. Bye, Benjamin.

Re: Default record order...
Richard, I guess your problem comes from the fact that SQL has no concept of internal order. If you do not specify an ORDER BY clause, the order or records returned is undefined, i.e. random. That's what I was figuring. I asked because I wanted it confirmed. Thank you. Of course, MySQL has some kind of internal order depending on many factors, but you may not rely on it. And neither you may rely on the fact that a PRIMARY KEY influences the internal order. You have to use an ORDER BY clause if you want to get a sorted result (of course, you want a key to speed up the ORDER BY clause). Hmmm. Perhaps I'm misled by the default behaviour of other database engines, but I was taught that the primary key was stored in the database to optimize search/insert/delete - which meant *sorted*. That is why you don't want a large (complex) primary key on tables that must run fast - the overhead of sorting each insert/delete negatively affects performance. Or so I was taught, anyway (back in the dark ages - primative data structures and all that G). As others have said, this is not part of the relational model. However you are correct - back in the 'good old days' we could rely upon hierarchical databases to do this, and I'm fairly sure that the early 'SQL' DBMSes also used to do this because they physically separated the Primary Key and the 'dependent part' of the row, so that any 'straight' listing would come out in PK sequence. =dn - 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: InnoDB frightens me...
You can use logical lock - set a STATUS int 0 (probably the ID of user) to indicate someone started to edit it interactively to block other user to edit the same record. Before you write it back to disk, read it again in a buffer to keep all data possible changed by batch updates. Or separate the table to 2 tables, one for each kind of update. Also I use a kind of transactions before I know that exists, I don't subtract from items directrly but I put it in a field named keeps. If user change his mind or something goes wrong, I only subtruct from keeps fields.Otherwise I subtract from items and keeps. Of course I have create another temp file with the invoice. I use these methods several years now mainly with C-tree from Faircom, they work fine. But to tell you the true, I use Delphi with Interbase for this kind of application on the net. I don't know if it's possible with PHP. Can someone directs me to the avantages of Inno base comparing wtih default MySQL? Row locking is the bigest one as I can read here?

Leif, I want to select and join data from two tables if the same id exists in both tables. If the id only exists in one table I want MySQL to return a string like sorry, no records found.

Re: Why v3.23.49 does not build on RedHat 6.2 ?????
hi! the source rpm for mysql 3.23.49 contains build instructions for gnu compilers 2.95 or newer. redhat 6.2 comes with a compiler that cannot handle the permissive flag (i think its ecgs-2.91). A-HA!!! Thanks a lot! therefore the build fails. one solution could be to install a more recent compiler version and try to recompile again. I'll try this solution before upgrading my system be aware that actual rpm's will be created by rpm version 4, whereas redhat 6.2 has rpm version 3 Yes, but v4 version has been made available. Actually I'm running 4.0.2 besides that, there may be glibc issues. redhat 6.2 has glibc 2.1.3 installed. i don't know if actual gcc or mysql versions work ok if compiled against this 'old' glibc. Binary rpms released by the mysql team were working on my system till v3.23.48. I Hope I'll be able to compile this new version against glibc 2.1 . if you dont have very specific reasons to stick with redhat 6.2 in my opinion it could be simpler just to install a later redhat version... Unfortunately my server 'lives' in another town but It looks like it will receive a visit soon. :o) not sure if this really helps... It did!

RE: InnoDB frightens me...
Sure seems that way to me. Same SQL engine no matter what table type you use. InnoDB didn't scare me. Pretty friendly to use. :) --Walt -Original Message- From: Jeremy Zawodny [mailto:[EMAIL PROTECTED]] Sent: Tuesday, March 05, 2002 2:09 PM To: [EMAIL PROTECTED] Cc: Tobias Lind - Telia Internet; [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: Re: InnoDB frightens me...

In particular some sample update/insert/delete db code for MyISAM vs. InnoDB, (especially in the case where you're not adding transactions, just trying to take advantage of row-locking.) Assuming something changes, of course. The other thing is a page on replication issues. If you're not using transactions, the code is identical. Really. It's easy. :-) Jeremy -- Jeremy D.

DROPing DATABASE can halt a replication slave.
Description: A slave replication only one of many databases from a master will fail with a error 'Can't read dir of './otherdb/' (Errcode: 2) on query 'DROP DATABASE otherdb' if the slave was not replicating that database. How-To-Repeat: Create a master with 2 databases (gooddb otherdb). Setup replication, allowing both databases to be replicated. Create a slave to replicate from the master with the line replicate-do-db=gooddb in my.cnf. After all is up and running on the master do a DROP DATABASE otherdb The slave will get the above error, even though it wasn't repicating that database it will try and remove the directory.
