MySQL bug? - problems with character-set
Hi!
I tested MySQL 3.23.51 under Windows and 3.23.49 under Linux RedHat 7.3 with
such SQL:
select lcase('HERE I TIPED IN SPECIFIC MY LANGUAGE CHARACTERS')
and recieved different results (of course, I used same config file with
case-sensitive configuration).
Result under Linux looks better, under window - wrong, because result
contain lower-case and upper-case symbols together
It's loks like this:'HErE I tIPED MY LaNGUaGE CHaraCtERS'
Now I feel confused, hov I can test, is my conf file.

Re: repeated crashes (buffer overrun?)
Colin, what version of MySQL you are running and on what OS? The assertion means there is an attempt to reference a pointer which does not point to the buffer pool. It might be memory corruption or table corruption. If you have updated to new disk drives in Linux, best to check if there are newer drivers. Please send me the complete error log so that I can resolve the stack traces if possible. Best regards, Heikki Innobase Oy ... We just brought a database back up after bringing it down for a hardware upgrade (added hard drives) and after we brought it back up it started crashing a lot. The queries that crash it vary. I realize it might be simple case of database corruption (the data files are now on a different physical drive) but I thought I'd post it here in case the logged messages ring any bells. Relevant info: InnoDB: Assertion failure in thread 24601 in file ../include/buf0buf.ic line 263 InnoDB: We intentionally generate a memory trap. InnoDB: Send a detailed bug report to [EMAIL PROTECTED] 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=268431360 record_buffer=1044480 sort_buffer=1048568 max_used_connections=19 max_connections=200 threads_connected=20 It is possible that mysqld could use up to key_buffer_size + (record_buffer + sort_buffer)*max_connections = 670938 K bytes of memory Hope that's ok, if not, decrease some variables in the equation Any ideas? - Colin - 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: maximum number of columns max row size
A rule of thumb I always follow is to design the DB so that you don't have to add columns (or modify the structure) unless something unforseen comes up (like a new feature). In your case, you are expecting to add variables in the future, so I would deign accordingly. Use rows instead of columns. Using rows also allows you to index all variable values and names, since there are only two columns. You couldn't index all your columns if you expanded horizontally instead of vertically. Besides, it's a heck of a lot easier to add a row than a column. On Thursday, August 1, 2002, at 01:09 AM, Michael Zelina wrote: Can someone provide insight into what a good maximum number of columns is in a MySQL database? I have an extensive list of variables for an engineering application which number in the 700+ range with more additions possible down the road. My question is: should I break up the variables into several tables for storage, or can I use a single table with this many columns. I cannot find any good rules of thumb for how much the number of columns effects performance. In trying to consolidate my existing data from Access (which limits columns to 255 per table) into a single table, I received the following error: mysql create table tblsessions select * from tblsessionfiles, tblsessionfiles2, tblsessionfiles3 WHERE tblsessionfiles2.sessionid_2 = tblsessionfiles.id38 AND tblsessionfiles3.sessionid_3 = tblsessionfiles.id38; ERROR 1118: Too big row size. The maximum row size, not counting BLOBs, is 65535. You have to change some fields to BLOB I assumed that the maximum row size is the total bytes for the entire row. My questions are: (1) can I change this without recompling MySQL and (2) should I really do this or just stick with three or more separate tables for performance reasons. FYI, I am running this on a well-equipped server and will probably only have a maximum # of concurrent users doing DELETE and INSERT in the range of 150 or so.

Selectable results
Hello,
In my web page I have MySQL retrieve information from
a database, and display it in a table. I would like to
make the results of the search selectable, as in, be
able to click on a field in my table and have it
preform a function. Here is the code for my table. I
would like $myrow[FileName] to be selectable, with
an onClick or onMouseover function.
if ($myrow = mysql_fetch_array($result)){
echo table border=6
;
echo trtdh3File Name/h3/td/tr
;
do{
printf(trtd%s/td/tr,
$myrow[FileName]);
}
while ($myrow = mysql_fetch_array($result));
echo /table
;
}
I would appreciate some help on the syntax.
Thanks, B

I'm trying to start up mysql through dos prompt. When I enter a command like c:\mysql\bin\mysqld or anything similar (any command in the bin directory), it just waits there. I can't Ctrl-C out of it. I can end the process to get out. What's happening? You just started the server. If you want to run it as a service (I assume you have Windows NT or 2000), use the --install option. Now, you could open another command prompt window and start mysql with, for example: mysql --user=someguy --password=secret Hope this helps. = - Benoit St-Jean [EMAIL PROTECTED] Yahoo!

Contact contains a persons first and last name, as well as their own ID. Address contains their street name, the city, state and a column called contactid for the id of the person who lives there. State is a foreign key for the state table and contactid is a foreign key for the contact's id. Now here is what I want to do: I want to insert a person into the contact database and then insert their address into the address table, but I want to somehow put the ID of the state, and the id of the contact into the fields without actually having to know the values. Like rather then having to look up New York and then insert 033, can I just somehow put New York? Is this possible to do?

various questions about my.ini /or my.cnf
As a newcomer to MySql, I have struggled through the install and am working my way through the tutorial. My environment: Win2000 MySql version 3.23.51-nt My.ini: [mysqld] # set basedir to installation path, e.g., c:/mysql basedir=c:/mysql # set datadir to location of data directory, # e.g., c:/mysql/data or d:/mydata/data datadir=c:/mysql/data # turn load data local option on local-infile=1 I am attempting to load table = menagerie from a text file name pet.txt. To make this work I have had to do the following: 1. Include local-infile=1 option on the login to mysql. Why is this not picked from My.ini? C:\mysql\binmysql -u jarkema -p --local-infile=1 2. Fully qualify the input file on the load data command. Why is the data path not being picked up from My.ini? mysql load data local infile c:/mysql/data/pet.txt into table pet; If I don't fully qualify the input file name I get: mysql load data local infile pet.txt into table pet; ERROR: File 'pet.txt' not found (Errcode: 2) It doesn't appear that my.ini is being used by mysql.

Problem under high load
Hi all-- I'm running a PHP/Apache/MySQL web app on a server. Specs are: Slackware Linux v8.0 Kernel 2.4.16 Dual Athlon MP 1.2 GHz processors on a Tyan S2460 Mobo 1 GB registered ecc ram I'm running MySQL 3.23.51-log, I believe, and it's the binary version for x86 supplied by MySQL. The problem I'm having is that under high load, (i.e. 250 connections to mysql server), it seems to just stop executing queries. Up to that point, it handles about 80 queries/sec. The mysql memory footprint grows to about 50 M, according to top. Then, for no apparent reason, it stops handling queries. vmstat shows that there are about 290 processes waiting for run time, although disk activity remains low. I have swap space set up on an independent drive (IDE, with UDMA2), and it's not using much of that anyhow. I've set my key_buffer to 196M, open_tables to 1000 (and /proc/sys/fs/file-max is at 4096), and reasonable defaults (from my-large.cnf) for pretty much everything else. I've analyzed all of my queries, and none of them seem to be slow. Some have using temporary and a few have using filesort, which i know is awful, but there's no reason it's going, going, going, dead. Any help would be greatly appreciated.

Re: Error in using source command with PHP
That is because source is a mysql client command, not as sql command. It gets executed by the client 'mysql'. The 'mysql' client reads it line by line, and passes the lines to the server. The server never sees the scriptfile.sql. You will have to write a PHP modules that reads the file, and passes it lin-by-line to the server, or have PHP execute the mysql client, passing it all options and parameters.

Re: maximum number of columns max row size
Hi Brent, Thanks for the response. Currently, I have the variables listed out in a table with one variable per row... something similar to the following: ++--+- | ID | DimensionName| ++--+- | 1 | units_length | | 2 | units_temp | | 3 | dim_positionX| | 4 | dim_width| | 5 | dim_length | ++--+- So, I can easily add dimensions or remove them as needed. The problem I have concern about is storing the dimension values a user inputs for a given session.

Using the ID value as the column provides some abstraction so I can rename dimensions and the sessions are still valid. Any thoughts on how better to store the session data? Since I am coming over from Access, I currently have three tables with 255 columns each.

Re: maximum number of columns max row size
I thought you were coming from some other database. I haven't heard dimension since my FoxPro (on the Mac) days. Since session data is temporary, you should use temporary tables to store you session variables. Just use the real table to hold you default values. You want to do something like this at the start of a session: create table SessionVars SELECT * from SessionDefaultsTable Then you just read or update the SessionVars table as needed. MySQL will handle the creation and management of the table and that temp table will be unique to each user, so you don't need to worry about table name conflicts, MySQL handles it. Also, MySQL handles dropping the table when the user disappears, so you don't have to worry about cleanup. Read up on temporary tables, I think they would help you considerably in this situation.

Re: How to speed up slow query from OR
If running two queries is running faster than perhaps the best way to do it is select the first query into a temporary table and then insert select the second to append to the temp table. Then you can select and sort however you want from the temporary table. create table tempname SELECT something from table... insert into tempname (something columns) SELECT something from table... select something from tempname order by column Three steps instead of one, but if it runs faster then it helps.

RE: maximum number of columns max row size
The way you store session values, as you said, can be troublesome when new dimensions are added, or existing ones removed. Also it might be constrained by some column limit. I'd try something like this, +--++-+---+ | SESSIONID| UserID | DimensionID | Value | +--++-+---+ | session_abcd | 100| 1 | 1 | | session_abcd | 100| 2 | 1 | | large_design | 200| 1 | 7.25 | | small_design | 100| 1 | 8.0 | | ... | ...| ... | ... | +--++-+---+ This might help you expand/shrink dimensions a little easier. One obvious drawback with this approach is that we are fixing all dimension values to a single type, say double. In order for this to work, you'll need to define IDs for each possible character values, which might or might not work for your situation. Hope it helps.

Re: maximum number of columns max row size
It's funny how terminology can be so confusing! When I say dimension, I mean engineering-wise as in the distance from a to b. Also, my use of session probably wasn't a good word in this context. Our sessions are actually permanently stored, since they are associated with a particular engineering job. The user may want to recall a past job to review the inputs and/or recreate the design. That said, the temporary table information is useful... I may need that to manage the system once we change the user interface from a single page to a step-by-step approach.

MySQL will handle the creation and management of the table and that temp table will be unique to each user, so you don't need to worry about table name conflicts, MySQL handles it. Also, MySQL handles dropping the table when the user disappears, so you don't have to worry about cleanup. Read up on temporary tables, I think they would help you considerably in this situation.

Currently, I have the variables listed out in a table with one variable per row... something similar to the following: ++--+- | ID | DimensionName| ++--+- | 1 | units_length | | 2 | units_temp | | 3 | dim_positionX| | 4 | dim_width| | 5 | dim_length | ++--+- So, I can easily add dimensions or remove them as needed. The problem I have concern about is storing the dimension values a user inputs for a given session. For this I now have a table defined as follows that maps to the ID of the variable list table: +--+--+--+--+--+ | SESSIONID| ID1 | ID2 | ID3 | ... | +--+--+--+--+--+ | session_abcd | in | F| 5.5 | | | tesfile1 | in | F| 6.0 | | | large_design | in | F| 7.25 | | | small_design | in | F| 8.0 | | +--+--+--+--+--+ 4 rows in set (0.04 sec) This way, I can have the values stored as a single row and easily delete and add session file values from the database. Using the ID value as the column provides some abstraction so I can rename dimensions and the sessions are still valid. Any thoughts on how better to store the session data? Since I am coming over from Access, I currently have three tables with 255 columns each. Performance-wise it seems OK... and I'm wondering if I should consolidate the tables into one or leave them separated. Or if even with a 255 column table I might run into performance problems. Thanks again for the help, Mike Brent Baisley wrote: A rule of thumb I always follow is to design the DB so that you don't have to add columns (or modify the structure) unless something unforseen comes up (like a new feature). In your case, you are expecting to add variables in the future, so I would deign accordingly. Use rows instead of columns. Using rows also allows you to index all variable values and names, since there are only two columns. You couldn't index all your columns if you expanded horizontally instead of vertically. Besides, it's a heck of a lot easier to add a row than a column.

FreeBSD/MySQL 4.0.2 and UNION buggy?
Is anyone else seeing odd problems with heavy use of UNIONs on a MySQL 4.0.x server on FreeBSD? I seem to be able to induce the problem on FreeBSD but not Linux.

The data conversions are automatic in the server. abcd + 0 is 0 1234 + 1 is 1235 Use the data type field to select the correct input validation routine, but store everything as a varchar. You can then make up your own datatypes, like state or city, or phone. Perl is typeless anyway. If you do math it is a number. If you concat two variables, then they are strings.

InnoDB: Looong pause when log file is full?
Hi, I've read the performance tuning tips for InnoDB (http://www.innodb.com/ibman.html#InnoDB_tuning), but am getting bit when the log files are full and the buffer pool is checkpointed. By 'geting bit', I mean for several minutes the db server basically stops, and our website stops serving pages. Does anyone have advice about what we can do to alleviate this? Instead of having three 150mb log files, would we be better off with 30 15mb log files? Our log files are on the same raid array as the data, but would it really make that much difference to move them to a separate disk? Alternately, is there a way to trigger this action at night, so we can avoid it happening during the day? It shut us down for about five minutes today. Details follow.

I was wondering about the Enum and Set column types in InnoDB tables. I was able to create an InnoDB table with an enum column, but i get errors when trying to insert values into that column.

ORDER BY question
I am performing a query along the lines of the following: SELECT DISTINCT property.Internal_ID FROM property, owner_names WHERE property.Internal_ID = owner_names.Internal_ID AND [ other conditions ] ORDER BY owner_names.Name Without the order by clause this is a pretty quick query, but with it, things slow down considerably. The query then takes 5-10 times as long. :( the property table has 1,000,000+ records and there are an average of about 1.4 owner_names records for each property record I'm not exactly sure what happens with the ORDER BY clause, because if a property record has more than one owner_name record associated with it, how does MySQL decide which to use for sorting? I'd guess that if there are more than one, it will take the first one in sort order. The owner_names table also has a field named Display_Order, which determines in what order to display the names for mailing labels, etc. I'd really like the ORDER BY to only consider records with Display_Order = 1, but the SELECT to consider all owner_name records. I know you can put some types of expressions in an order by clause, but i don't know how to express the above concept in SQL. thanks sean peters [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?

problems when a combination of join, select distinct and order by are used together.
Description: When we join two or more tables, select distinct and order by on a column, we get problems. How-To-Repeat: mysql select * from test; +--+--+ | a| b| +--+--+ |1 |1 | |2 |2 | |1 |3 | +--+--+ 3 rows in set (0.00 sec) mysql select * from test as a1, test as a2; +--+--+--+--+ | a| b| a| b| +--+--+--+--+ |1 |1 |1 |1 | |2 |2 |1 |1 | |1 |3 |1 |1 | |1 |1 |2 |2 | |2 |2 |2 |2 | |1 |3 |2 |2 | |1 |1 |1 |3 | |2 |2 |1 |3 | |1 |3 |1 |3 | +--+--+--+--+ 9 rows in set (0.00 sec) mysql select * from test as a1, test as a2 order by a2.b; +--+--+--+--+ | a| b| a| b| +--+--+--+--+ |1 |1 |1 |1 | |2 |2 |1 |1 | |1 |3 |1 |1 | |1 |1 |2 |2 | |2 |2 |2 |2 | |1 |3 |2 |2 | |1 |1 |1 |3 | |2 |2 |1 |3 | |1 |3 |1 |3 | +--+--+--+--+ 9 rows in set (0.00 sec) This is the problem: mysql select distinct a1.a from test as a1, test as a2 order by a2.b; +--+ | a| +--+ |1 | |2 | |1 | |2 | |1 | |2 | +--+ 6 rows in set (0.00 sec) mysql select distinct a1.a from test as a1, test as a2 order by a1.b; +--+ | a| +--+ |1 | |2 | |1 | +--+ 3 rows in set (0.01 sec) Interestingly, the query without the order by works... :) mysql select distinct a1.a from test as a1, test as a2; +--+ | a| +--+ |1 | |2 | +--+ 2 rows in set (0.00 sec) Fix: Err... avoid putting order by or distinct together?

Exporting Multi-DataType Excel Worksheet to CSV for Import into MySQL
I have done a lot of looking and search through archives of mailing lists and newsgroups and I guess I haven't looked enough because I still haven't found what I'm looking for. What I have is an Excel worksheet that had 26 fields and several hundred rows of data. The data types will be are INT, TINYTEXT, and TEXT when they finally make it into MySQL. The TEXT and TINYTEXT fields contain commas, double quotes, single quotes, ampersands, dollarsigns, periods, and HTML tags. When I export it to CSV some of the TEXT and TINYTEXT fields only contain alpha characters and so they don't get quoted. My problem: I need all of the TEXT and TINYTEXT fields to be quoted and all of the INT fields to not be quoted (of course). Currently when I export to CSV and then LOAD DATA INTO MySql I get the error: ERROR 1062: Duplicate entry '1' for key 1 My import query is: LOAD DATA INFILE 'filename.csv' INTO TABLE tablename FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '\' LINES TERMINATED BY '\n'; I have check out the Text Write macro program and it doesn't take my need to have some fields quoted but not others into accout. I am sure someone else out there has done this. I am wondering what the best way to go about this is. Any help is greatly appreciated.

Re: MySQL bug? - problems with character-set
Hi!
It's just a simple example, because I don't want send latvian-specific
symbols. This problem occurs with latvian-specific symbols only.
Configuration file I cheked some 4-5 times. I'm confused now.
Regards from Latvia!

on my w2k and RedHat 7.1 box I got correct results:

What Windows do you use? How did you install MySQL from binary or from
source?
