Hi, May be this list was unresponsive because your description of the problem was a bit vague... I haven't experienced this kind of behaviour myself however some more details on your problem may help: - What OS are you using ? - What version of MySQL are you using ? - Was mysql server dead ? (Have you tried mysqladmin with ping, status or processlist options ?) - Have you checked mysql error log ? - When the problem happened, what kind of system activity have you seen ? Have you run top, vmstat (I assume you are on a Unix like OS) ?

Re: Really big text - where to get?
When you write another MySQL-based search engine, you obviosly test it issuing queries against big amounts of data which contains more or less sane text. Tell me, where (or how) you usually get the text when you need, say, 10GB of it and, I repeat, it should be a REAL non-repeating text, not just would-be words randomly generated with a filler script? 10G maybe a bit high, but when I wanted a few tens of MB to test MySQL FULLTEXT. I downloaded some books from Project Gutenberg and wrote a tiny app to split them into records with one sentence in each record. MySQL proved blindingly fast on the King James Bible (8Mb, 30,000 records).

group by help?
Hi I am having some trouble figuring out how mySQL interprets the group by clause in a particular set of data that I have (the ensembl database if anyone is familar with it!) Now, I have some data like this: +-++--+ | gene_id | display_id | db_name | +-++--+ | 24173 | Q9H701 | SPTREMBL | | 24173 | Q96GS5 | SPTREMBL | +-++--+ and this is produced by the following SQL: select t.gene_id, x.display_id,e.db_name from ensembl_core_test.objectXref as ox, ensembl_core_test.Xref as x, ensembl_core_test.transcript as t, ensembl_core_test.externalDB as e where e.db_name='SPTREMBL' and x.xrefID = ox.xrefID and t.translation_id = ox.ensembl_id and e.externalDBId=x.externalDBId and gene_id =24173; Now, the SQL is not important, what is is that we have two display_ids for one gene_id. Now, if we add a group by gene_id clause into the above SQL, then presumably mySQL must make an arbitrary decision on which display_id to choose. And the odd thing is that in the main ensembl database it chooses one, and in my local copy it chooses the other! So what I want to figure out is how mySQL makes that arbitrary decision - is it based on which it comes across first in memory, which it comes across last, alphabetical order, random choice (though mySQL is always consistent in which it chooses) ... or is there some other way it will make the decision? Furthermore, and more confusingly, mySQL chooses differently if I parameterise the SQL. For example: mysql create table test - select t.gene_id, x.display_id,e.db_name - from ensembl_core_test.objectXref as ox, -ensembl_core_test.Xref as x, -ensembl_core_test.transcript as t, - ensembl_core_test.externalDB as e - where e.db_name='SPTREMBL' and -x.xrefID = ox.xrefID and -t.translation_id = ox.ensembl_id and -e.externalDBId=x.externalDBId and gene_id = 24173 - group by gene_id - order by gene_id; Query OK, 1 row affected (0.00 sec) Records: 1 Duplicates: 0 Warnings: 0 mysql select * from test; +-++--+ | gene_id | display_id | db_name | +-++--+ | 24173 | Q9H701 | SPTREMBL | +-++--+ 1 row in set (0.00 sec) compare this to: mysql create table test - select t.gene_id, x.display_id,e.db_name - from ensembl_core_test.objectXref as ox, -ensembl_core_test.Xref as x, -ensembl_core_test.transcript as t, - ensembl_core_test.externalDB as e - where e.db_name='SPTREMBL' and -x.xrefID = ox.xrefID and -t.translation_id = ox.ensembl_id and -e.externalDBId=x.externalDBId - group by gene_id - order by gene_id; Query OK, 11674 rows affected (6.84 sec) Records: 11674 Duplicates: 0 Warnings: 0 mysql select * from test where gene_id = 24173; +-++--+ | gene_id | display_id | db_name | +-++--+ | 24173 | Q96GS5 | SPTREMBL | +-++--+ 1 row in set (0.01 sec) So here we see that mySQL has chosen differently simply because of the presence or absence of the gene_id = 24173 in the create table command I want to try and figure out why mySQL is making these rather inconsistant decisions and see if it's possible to remove this feature Thanks for your time, if there is another mailing list which is more appropriate, please tell me!

Max 127 records
Hey - can anyone help?
I have a MySql-db in which I can only have 127 records.
Using phpmyadmin to insert record number 128 (autoincrement) gets this message:
INSERT INTO `kontakt` (`id`, `navn`, `adresse`, `postnummer`, `by`, `telefon`,
`kommentar`) VALUES ('', 'fsd', 'sfdg', 'sg', 'fdsg', 'sfg', 'sg');
MySQL returnerede:
Duplicate entry '127' for key 1
No matter what table or desing of table - the result is the same. Using other
interfaces than phpmyadmin gives the same result too.

This is a classic :-)
You've created your primary key (the autoincremented field) as a TINYINT,
which only allows values in the range -128 to 127. auto_increment does not
support negative numbers, so when you've filled the first 127 records, it
cannot add any more values.
Alter the field to a INT UNSIGNED, then you're good to go

Your table has an auto_increment column of type 'tiny int'. This allows
values between -128 and 127. You should choose a different column type.

Re: Max 127 records
WowI think I can finally help somebody on this list.
Ok. I bet that you have your column set up as tinyint. I presume it
would be the id column that you have. tinyint is the following:
Signed values: -128 to 127
Unsigned values: 0 to 255
I ran into the problem before too. So if you want to go past 127, you
either need to set it as an Unsigned value, but that will only let you go
to 255, or set it to another int. smallint will go to 65535 (Unsigned),
mediumint will go to 16777215 (Unsigned), etc.
Happy to finally be able to help. :)

Re: Max 127 records
A closed mouth maintains a happy mind.
It could be that you specified signed TINYINT as type for the PRIMARY
KEY. Signed TINYINT goes from -127 to 127, hence your problem.

This happens when the key is defined as a tinyint, a single byte datatype.
Change the column to a smallint (2 bytes), mediumint (3 bytes) or int (4

Re: group by help?
mysql is acting correctly. GROUP BY is used to consolidate data for SUMming, COUNTing, etc. Your SELECT statement makes not such request. You have simply requested the value of a specific field. Data are stored in mysql databases randomly. Therefore, when you request a field's data, you are getting whatever is first in the list of records matching your WHERE clause. Bottom line: you are NOT using GROUP BY as it is supposed to be used.

Re[2]: SELECT the first letter MATCH in mySQL
Hello Paul, But RLIKE won't use indexes (even if they exist), so why RLIKE '^A' is better than LIKE 'A%', if LIKE which starts at the beginning of the string **will** use indexes? Regards, Tom PD Regular expression patterns (unlike SQL patterns) don't need to match the PD entire string, so RLIKE '^A' is sufficient and more efficient because PD it doesn't spend time trying to match anything other than the first PD character. PD As to the original question (below), that query looks like it should PD work. Perhaps the problem lies elsewhere in the code that executes PD the query. (It may be the query gets modified somehow. Without seeing PD the context, it's hard to say.) - 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: Max 127 records
Are you saying that you want a table with a maximum of 127 records ? Or,
that due to your TINYINT, you are RESTRICTED to 127 records?
If you are restricted to records, change TINYINT to INT.
If you want to have ONLY 128 records, change TINYINT to TINYINT UNSIGNED,
which will permit records 1 through 255.
FYI: show us your table structure next time; please don't force us to guess
your structure

Subject: Max 127 records
Hey - can anyone help?
I have a MySql-db in which I can only have 127 records.
Using phpmyadmin to insert record number 128 (autoincrement) gets this
message:
INSERT INTO `kontakt` (`id`, `navn`, `adresse`, `postnummer`, `by`,
`telefon`, `kommentar`) VALUES ('', 'fsd', 'sfdg', 'sg', 'fdsg', 'sfg',
'sg');
MySQL returnerede:
Duplicate entry '127' for key 1
No matter what table or desing of table - the result is the same. Using
other interfaces than phpmyadmin gives the same result too.
Thanks for helping
Henning

My SQL ++ Bug and Port
I am working with the MySql++ 1.7.9 on windows98 using borland C++ 6.0.
I have found and fixed a memory leak ( applicable on all platforms that need
the __USLC__ conditional defined) , and sucessfully ported the system to
borlanbd C++ 6 with a very minimum of modifications. (mostly resolving
include file differences between compilers). I would be willing to submit
the port back to mysql, but i am not sure who to contact about it.
The memory leak is in the function string SQLQuery::str(const SQLQueryParms
p) const, starting on line 98 of sql_query.cpp (.cc ? I may have changed
the extentions.) This is the fixed function:
string SQLQuery::str(const SQLQueryParms p) const {
SQLQuery *const_this = const_castSQLQuery *(this);
if (!parsed.empty()) const_this-proc(const_castSQLQueryParms(p));
*const_this ends;
#ifdef __USLC__
strstreambuf *tmpbuf = const_this-rdbuf();
uint length = tmpbuf-pcount() + 1;
char *s = new char[length];//isnt this a memory leak?
#else
uint length = const_this-pcount() + 1;
char s[length];
#endif
const_this-get(s, length, '\0');
const_this-seekg (0,ios::beg);
const_this-seekp (-1,ios::cur);

As a relational database, it doe not matter the order in which data are stored. Rather, what matters are the methods by which data are extracted via the SELECT statement.

Re: group by help?
It's ok, I do actually fully understand relational database theory and what the group by statement is used for, but like I say, I personally have no control over the database or the SQL :-) I was hoping to get hold of someone who maybe knows the source code quite well already and could help me out before I take the drastic step of trawling through the source code myself. It does strike me that, on the rare occasions when a truly arbitrary decision must be made, when there is a choice but it really doesn't matter which is chosen, there is no method in relational databases to make this choice in a consistent manner. A tough task probably, and obviously group by is not the perfect answer, but you can see why the developer made that choice as it does make mySQL make an arbitrary decision... just not a consistent one :-) Thanks Mick Richard Emery wrote: As a relational database, it doe not matter the order in which data are stored.

My problem was that interactively I could not get the following statement to
execute (on Win NT, myISAM table, mySQL 3.23.49-nt):
insert mytable values (1, 2 ,3, LOAD_FILE('c:\myfile.ext'));
However, I found this would work:
insert mytable (col1, col2, col3) values (1,2,3);
update mytable set col4 = LOAD_FILE('c:\myfile.ext')) where col1 = 1;

FW: BSD: Random unknown database error
Update: After finding a reference to problems with BSDI and the realpath() system call in the mailing list archives, I tried rebuilding MySQL with the HAVE_BROKEN_REALPATH flag defined. That seemed to clear up the problem, at least with the testing that I performed. YMMV. DSC _ Dan S. Camper Borrowed Time, Inc. Software Thaumaturge http://www.bti.net -- Forwarded Message From: Dan S. Camper [EMAIL PROTECTED] Date: Thu, 18 Apr 2002 12:41:31 -0500 To: MySQL [EMAIL PROTECTED] Subject: BSD: Random unknown database error All: Recently I've run into a problem where I intermittently receive an Unknown database error while attempting to communicate with a local MySQL server. I read through the mail list archives and discovered that others reported similar problems under BSD, but I didn't see any concrete solutions. I may not be able to provide a solution, but I believe I can pinpoint the cause. Let me apologize now for the length of this message. I'm trying to explain enough so that someone else, more knowledgable about MySQL's internals, can either use it to solve the problem or refute my guess. First, my environment: MacOS X (10.1.4), MySQL 3.23.49, running on a G3 PowerBook (Firewire), latest dev tools from Apple. The MySQL server is running on that system as well as my own C++ code. Before seeing the problem within MySQL I found a problem with my own multithreaded code. Each thread is responsible for loading a file in one directory and then manipulating a couple of other files in a different directory, all referenced relatively to the application's directory. When the load got high -- there were many concurrent threads -- I would intermittently receive an error from the OS telling me that one of the files I was trying to open could not be found. Given that the file in question was one that was supposed to always be present, I grew suspicious. After a bit of debugging, imagine my surprise when I discovered that the full pathname the OS was trying to use was wrong. Example Source file:foo/text.txt Dest file: data/index.txt App directory: /Users/lordgrey/Projects/myproject/ When the problem occurred while opening the dest file, referenced relatively, the OS was actually trying to open: /Users/lordgrey/Projects/myproject/foo/data/index.txt instead of /Users/lordgrey/Projects/myproject/data/index.txt Once I nailed down a variable with the current working directory at application launch time and used that to fully qualify my datafiles, all of my problems disappeared. As further testing, I started cranking up the number of threads. Now, in addition to dinking around with files, each thread has its own MySQL connection. Increasing the number of threads started causing the unknown database error to appear, pretty much in direct proportion to the number threads. The other problem reports in the archive noted that the unknown database problem seemed to occur when the system's load was high. That would agree with what I found. Anyway, it occurs to me that MySQL is failing to find a database -- which is a directory -- for the same reason that my code couldn't find its own data files. Namely: MySQL is using a relative path, BSD is mucking around with the concept of current working directory incorrectly and it's colliding with other concurrent threads also trying to use relative paths. I haven't picked the MySQL source code apart to see if this is really the case or not, but it seems reasonable. If it's true then the actual problem lies in BSD/MacOS/etc. but it can be worked around in the MySQL server.

Re: table-building advice requested
Hi, I am following up on a thread I started yesterday about building my tables. (I have included the original email at the end of this one for reference.) I got some good feedback about it, and so have decided to change my entire battle plan, and was hoping to get some advice about it. The scenario is this: a table exists called properfiles, and its columns keep track of various attributes of files. Each record is a file, of course. These files have been properly entered into the database using a PHP application I am writing, and thumbnails have been uploaded to the filesystem for each of these records. A user can use the application to select any of these files to be printed, adding the files to a shopping-cart-like object. But in addition to printing these already-existing files, the user needs to be able to define their own files to be printed -- these don't already exist in the database. However, I would like to keep track of them, since they are being printed. So here's the dilemma -- I've got some proper files that have been entered properly into the database, and have a great deal of information stored about them, and I have some user-entered files that have been entered only for the sake of being printed. The attributes of a user-entered file are different from the attributes of a proper file. Should I have one big table named files which keeps track of both kinds of files? This seems dodgy to me -- that would mean that some columns would be for proper files (meaning that a user-entered file record would have a null value for that column) and some columns would be for user-entered files (so proper files would have a null value for that column). Is this an acceptable database design? Originally I was thinking of storing each in its own table -- properfiles and userfiles, and having a prints table act as a foreign key, storing one-to-many relationships between properfiles and userfiles (for each print there could be any combination of properfiles and userfiles). But this would require having some way of tracking whether the file_id matches a proper file_id or a user file_id. It doesn't seem very smart to have a setup like this. So I think I should go with the big files table and just have some columns that apply to some kinds of files and not to others. Is this done? I'm just hesitant to have a lot of null values in my table. What do you think? Thanks for reading! Thanks even more if you can help me. Erik On Thursday, April 18, 2002, at 03:52 PM, Erik Price wrote: Hello, I was hoping to solicit some advice on the structure of the database I am building. Here is a simplified version of my scenario: The application that I am designing, in PHP4.1.2 with MySQL (3.23.46 on RedHat 7.2), has a feature which allows it to keep track of graphics files (JPGs, GIFs, PSDs, AIs, QPTs, etc), which are stored on CDs in a CD cabinet. I have already designed a table to store information about files, where each row is an individual file and each column is an attribute of that file. mysql describe files; +-+---+--+-+-+ | Field | Type | Null | Key | Default | +-+---+--+-+-+ | file_id | int(10) unsigned | | PRI | NULL| | file_name | varchar(64) | | | | | filetype_id | smallint(5) unsigned | YES | | NULL| | stor_id | mediumint(8) unsigned | YES | | NULL| | file_size | float(4,2)| | | 0.00| | width_in| float(4,2)| | | 0.00| | height_in | float(4,2)| | | 0.00| | file_res| smallint(5) unsigned | YES | | NULL| | cre_date| date | YES | | NULL| | insert_date | datetime | YES | | NULL| | inserter_id | smallint(5) unsigned | YES | | NULL| +-+---+--+-+-+ (there are other tables that relate to this one, but they are not relevant to my problem) Using my application via a web browser, users can select existing file records which need to be printed, and store them as objects into an array (actually a session variable array), similar to a shopping cart. Later, they will use another section of the application to check out, meaning each object in the array will become a row in another table (printedfiles), representing files that have been selected to be printed. (What happens with this data is irrelevant to my problem) The problem comes into play here: in addition to files they have selected from the database (let's use the alias files since they are all rows from the files table), users may also select files which do not exist in the database yet -- let's use the alias user files. I do not wish to store user files

RE: FW: Mysql unresponsive ....
Hi Joseph, The situation is like this. The daemon was running but any command / requests were hanging for example any mysqladmin command would sit there forever, any mysql command would behave the same way. OS - HP-UX 10.20 Mysql version - 3.23.33 There were lot of activities at the time server hung-up. But even after users got out it was in the hung state. Nothing in the error log files to give any clues. thanks Vivek -Original Message- From: joseph.bueno [mailto:[EMAIL PROTECTED]] Sent: Friday, April 19, 2002 1:18 AM To: CHAUDHARY, Vivek Cc: mysql Subject: Re: FW: Mysql unresponsive Hi, May be this list was unresponsive because your description of the problem was a bit vague... I haven't experienced this kind of behaviour myself however some more details on your problem may help: - What OS are you using ? - What version of MySQL are you using ? - Was mysql server dead ? (Have you tried mysqladmin with ping, status or processlist options ?) - Have you checked mysql error log ? - When the problem happened, what kind of system activity have you seen ?

If there a way to use the INSERT command and extract the new AUTO_INCREMENT all in one command? LAST_INSERT_ID() returns the last auto-incremented number for your database connection. Yes, this means that even if you execute this and someone else has auto-incremented the table in the meantime, you will still have your auto-incremented number (not the new, higher one). That is why this function is better than doing SELECT MAX() on that column. Erik Erik Price Web Developer Temp Media Lab, H.H.

Specifying Error Log
I think it would be a good idea to be able to specify the error log on the command line when starting mysqld. Right now mysql users can only specify the following logs on the command line: log (access/activity log) log bin log bin index log update log isam log slow-queries innodb_log_* I would love to be able to specify the error log on the command line. log error ( by default-only it is $MYSQL_ROOT/var/`hostname`.err ) mysqld --log-error=/usr/mysql/logs/error.log Maybe some people don't like that it is flagged as an error log.

how do i applying an equation to every row of a result set?
I am trying to normalize a data set based on the minimum values of certain columns. I figured out that I can get the minimum value using a query like SELECT least(min(colOne),min(colTwo)) FROM myTable Is there a way I can do the normalization in a single query? Ideally, something like... SELECT colOne-least(min(colOne),min(colTwo)) FROM myTable I realize that that does not work and maybe I need some kind of join. Is it possible to apply that subtraction to every row of the result set when it is returned?

Large text amounts into a mysql table?
Hi! I admit I´m a newbie but I´m really trying to get a grip on this... I have suceeded in creating an administration solution for websites and now one problem remains: When the values for a new website is submitted into a mysql table, it doesn´t work if the amount of text in the values are too large. I have set the actual cell to mediumtext, so that shouldn´t be the problem. I have tried to find the answer to my question in different forums, but the only result I have got is that it may have to do with the max-key limit? I mean, in the address field in my web browser all the text is visible when submitted successfully, is there a limit on how long this link can be? Anyway, how can I submit large text amounts into a mysql table? A lot of thanks in advance, Jonas Andersson _ Do You Yahoo!?

Intermittent 1049 error
Hello, I'm running a relatively busy MySQL server on Mac OS X Server. MySQL runs on a dedicated dual G4 500, with 1.5 GB of RAM and an 18GB 15k rpm Ultra160 Cheetah drive. No other services besides MySQL run on this machine. Roughly 3-5 times per day, my MySQL server suddenly forgets most or all of its databases, and begins claiming that they don't exist with an error 1049. I've searched the mailing list (found 3 messages with 1049 in the archives, none of which described this problem), the online docs (error 1049 isn't even mentioned), and Google (which found 150+ pages who are apparently having this same problem, but found no answers) ... I can't believe I'm the only one having this problem, but since there's no mention of it anywhere that I can find, I am beginning to wonder. Can anyone shed some light on this issue, and hopefully, offer a remedy? Thanks in advance. -Clay ( Further info -- the server hosts only about 15-20 databases, the total size of which is less than 1.5 GB.
