problem with long query!
We have the following problem: on the server (quite fast) we have the Mysqld-nt daemon running ; and the data resides in it. When a user access the server with a very long query and another try to do the same , but with a very simple query ; the last one has to wait a very long time because of the first query takes almost all the resources (100% CPU time when it should not !) ...when normally it would take 2 or 3 seconds... Is there a way ( some variables to set , some specific commands,OS configuration or whatever!) to make the server stop for a while the thread concerned with the long query , execute the simple query , and return back to its job?...in short: how could we optimize and better balance the server load ? We tried several solution , like changing variables like key_buffer_size , join_buffer_size etc. Change some TEXT fields in CHAR fields but it does not seem to work . You know where the problem is ?...if in a big office one launch a long query ( in our case it could happen) the other clients are almost stuck! TIA C. P.S. We use a Visual Basic-like programming language to build our application , and we access the data via MyODBC 2.5 and ADO. Normally the LAN we are dealing with are of peer-to-peer type. __ Tiscali ADSL. Scopri la fantastica promozione di Natale: tutto Gratis fino al 9 gennaio!

Sequence of SQL actions gives wrong query result for 10 seconds!
All,
I've been having problems with a pretty simple series of SQL statements run
against some InnoDB tables returning the wrong results - temporarily!
Basically, I have one middle table that maps a role to an operation
(many-to-many), and I have separate role and operation tables that contain
respective descriptions for the codes. If I remove all the rows for a
particular role id from that middle table and run a SELECT looking for
that role and joining to both other tables to get relevant descriptions, I
get erroneous rows back! (The number of rows seems to differ depending upon
whether my isolation-level is SERIALIZABLE or READ_COMMITTED.) These
erroneous rows continue to be returned until about 10 seconds after I've
committed the transaction, when I receive the correct Empty set response.
I've managed to come up with a fully repeatable test that I'll include
below. (I'm not sufficiently familiar with MySQL that I know how to use the
test script or whatever it is, and I don't think it came with my Windows'
binary distribution anyhow. Hopefully I'm providing enough info to make it
easy anyway...)
I'm running mysqlmax 3.23.52 on Win2k. I understand there's a .53 in
existence but I checked the change-logs and they didn't mention anything
about a problem like this having been fixed.
The script follows. After that, there's the mysqladmin variables output and
the (not-very-pretty) results I get when running the test - though it should
be dead easy for anyone to replicate using the script (as long as it's not a
problem with my setup). BEWARE - the script drops / creates tables. Note
also that I'm running in ANSI compatible mode. (Oh - one last thing: I may
be off track, but I seem to recall that not having primary keys on the
tables (when I was trying to produce my test-script) affected the results.)
Any info appreciated! Thanks,
Mike.

Hi Ben, As far as I know the algorithm used for the decrypting is a one-way hash function, thus there is no way of decrypting it. You may consider to reset the password and mail the user the new one instead of mailing the old password.

Help! problem using MySQL C API
Hi,
I'm having trouble writing dial-up user billing software in C using MySQL C
API.
Program suppose to send query to mysql server and retrieve records and
process those.
It sends query for each class_id for every day and get records from
ACCOUNTING table.
While retrieving records it adds user in linked list if user doesn't exist.
There will be total not more than 1000 users
per one day with duration, number of session, time_stamp etc. After adding
user to linked list it calculates
the charges for duration that he connected to Internet. In order to
calculate charge it sends various queries to
various tables to get data. Program is working fine for one day. But when I
try to calculate from beginning of the
month, after 2 days program crashes saying:
Out of memory (Needed 8164 bytes)
select charge,from_min,to_min,class_id,id from customers.intervals where
class_id='19' order by id query failed!
when sending trying to send query to get data for calculation.
I think there are some problem with memory management, but when I just run
program without calculating charges
it works just fine.
Can somebody recommend me better way of handling in this situation? Is this
good choice to use linked list in this case?
Is there any other good resource for writing mysql client in C on the web?
Please let me know if somebody knows and solved this problem before.
Please give me some recommendation in this regard.
I'm using FreeBSD 4.6-STABLE, with 512 MB RAM and 50GB HDD with 6GB of free
space.

newbie stuff: good mysql books?
Greets Folks, I have been wanting to get into data driven sites for the longest time, and I can do some immediate level work in them using perl, but my understanding is still not comprehensive enough for whatever it is I want to do (subconsciously). I sense there is some need to pursue database design better, and an overall book on system's design might be good too. I've read MySQL and Perl for the Web by Paul, and Programming with CGI.pm, and both helped a lot. But there is some sort of a want to work specifically with the database more, especially design for largescale systems development, and I am just wondering what books might be good for this purpose?

Hello! mysql Ver 11.18 Distrib 3.23.53, for portbld-freebsd4.7 (i386) I have a problem with dumping data into databases. I dump the database with mysqldump into a SQL-File. So, i delete the database.

Sorting Records based on field
Having just walked into a job a few months back, one of the tasks I've been asked to accomplish is to counting records inside a DB based on a field. The database in questions holds realtor listings. There are fields for Company Name and Agent Name on each listing. What I need to do is sort records based on the Company Name and the itemize the number of ads per Agent and show that in a report. The Agents may change from time to time so keeping a table for a Company with only the agent names may not be a solution. Is there a way to pull these records in this fashion in MySQL? Like I said all the information is stored in one table with fields for Company name, Agent name, price, city, county etc.. Example: Realty Company 1 -- Agent 1 10 ads Agent 2 8 ads Agent 3 20 ads Realty Company 2 -- Agent 1 15 ads Agent 2 3 ads and so on Thanks, Ed Curtis - 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?

MySQL++ Memory leak
Background:
MySQL++ ( libsqlplus ) is a pretty nice official C++ styled mysql client
library wrapper of libmysqlclient. It offers STL-style C++ interface and is
designed with an effort of generic programming style. It should be a really
excellent choise if only it had not a MEMORY LEAK problem.
http://www.mysql.com/downloads/api-mysql++.html
Investigation:
As this library is commonly used to develop a CGI C++ application problem is
not so crytical. CGI process lives just a few seconds and then dies, all
memory it have been using is deallocated by the system. I've fortunely found
this bug developing apache mod_rewrite program map application that should
stay alive all the apache lifetime. It cannot be restarted without httpd
restart, and if it craches it crashes apache too =(
I use a little subset of mysql++ capabilities
- Connection
- Query ( only Query::store )
- Result
Memory leak I discovered is located somewhere in Result::operator= and is
available only after update;
Proof of concept code is supplied.
It leaks 1 Mb of memory in 10 seconds executing about 12000 updates
I use Intel celeron 333, 2.4.18 linux kernel on late slackware distibution.
MySQL++ 1.7.9 built from source, no __USLC__ conditional defined
Workaround:
Recreating Result object each query elminates this problem.
But we still hope on MySQL++ development team, aint we =?

Note that I have been using just a little subset of MySQL++, further memory
leaks may follow.

Re: Sorting Records based on field
* [EMAIL PROTECTED] Having just walked into a job a few months back, one of the tasks I've been asked to accomplish is to counting records inside a DB based on a field. The database in questions holds realtor listings. There are fields for Company Name and Agent Name on each listing. What I need to do is sort records based on the Company Name and the itemize the number of ads per Agent and show that in a report. The Agents may change from time to time so keeping a table for a Company with only the agent names may not be a solution. Is there a way to pull these records in this fashion in MySQL? Like I said all the information is stored in one table with fields for Company name, Agent name, price, city, county etc.. Example: Realty Company 1 -- Agent 1 10 ads Agent 2 8 ads Agent 3 20 ads Realty Company 2 -- Agent 1 15 ads Agent 2 3 ads This looks like two different results... a SQL query returns _one_ resultset. Try this: SELECT CompanyName,AgentName,count(*) as ads FROM table GROUP BY CompanyName,AgentName ORDER BY CompanyName,AgentName; URL: http://www.mysql.com/doc/en/SELECT.html The output could be something like this: ComanyNameAgentName ads - Realty Company 1 Agent 1 10 Realty Company 1 Agent 2 8 Realty Company 1 Agent 3 20 Realty Company 2 Agent 1 15 Realty Company 2 Agent 2 3 If you really want separate result tables for each company, you would probably need to use some programming language. -- Roger - 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: Sequence of SQL actions gives wrong query result for 10 seconds!
Mike,
thank you very much for a repeatable bug report!
This revealed an embarrasing bug in InnoDB SELECTs: if you selected with the
full value of a primary key, and the row which matched to it was
delete-marked, then InnoDB could in some cases return the NEXT row.
Since purge cleans off delete-marked records in the background, normally
after a few seconds you would again get the correct result.
I pushed the fix to the 4.0 tree, but am not sure if it makes it to 4.0.5.
The fix will also be in 3.23.54.
Thank you,
Heikki

Subject: Sequence of SQL actions gives wrong query result for 10 seconds!
All,
I've been having problems with a pretty simple series of SQL statements
run
against some InnoDB tables returning the wrong results - temporarily!
Basically, I have one middle table that maps a role to an operation
(many-to-many), and I have separate role and operation tables that contain
respective descriptions for the codes. If I remove all the rows for a
particular role id from that middle table and run a SELECT looking for
that role and joining to both other tables to get relevant descriptions,
I
get erroneous rows back! (The number of rows seems to differ depending
upon
whether my isolation-level is SERIALIZABLE or READ_COMMITTED.) These
erroneous rows continue to be returned until about 10 seconds after I've
committed the transaction, when I receive the correct Empty set
response.
I've managed to come up with a fully repeatable test that I'll include
below. (I'm not sufficiently familiar with MySQL that I know how to use
the
test script or whatever it is, and I don't think it came with my
Windows'
binary distribution anyhow. Hopefully I'm providing enough info to make
it
easy anyway...)
I'm running mysqlmax 3.23.52 on Win2k. I understand there's a .53 in
existence but I checked the change-logs and they didn't mention anything
about a problem like this having been fixed.
The script follows. After that, there's the mysqladmin variables output
and
the (not-very-pretty) results I get when running the test - though it
should
be dead easy for anyone to replicate using the script (as long as it's not
a
problem with my setup). BEWARE - the script drops / creates tables.
Note
also that I'm running in ANSI compatible mode. (Oh - one last thing: I
may
be off track, but I seem to recall that not having primary keys on the
tables (when I was trying to produce my test-script) affected the
results.)
Any info appreciated! Thanks,
Mike.

libc read hang?
Hello.
I have a problem with mysqld 3.23.49 .
My program consists of a father process and n children.
The children do a UPDATE at a certain time and the father might do a
SELECT at the 'same time'.
I suspect strongly that this is the problem. Any ways the father process
hangs at random situations
that involve the children doing UPDATEs and the father SELECT.
I am not sure of this.
What could be the problem?

Using MySQL with Perl 5.8?
Hi all, I was able to install the module DBD::mysql for Perl 5.6.1 using ppm (under Windows 2000) but after installing Perl 5.8, ppm can't find this module anymore. I could find only the module DBD::mysqlPP for pure Perl. I don't understand what pure perl means but I've seen that this module accepts less functions than DBD::mysql. Do you know if DBD::mysql works with Perl 5.8 and how can I install it? Thank you.

Hi, You can make your own authentification system.A table which can have a binary char/varchar field for encrypted password(effect similar like password from mysql.user) and another char for ASCII password.

Re: Is the mysql JDBC driver thread safe?
[EMAIL PROTECTED] wrote: Hi all, i'm planning on using servlets for an application I am building What I need to know is if there are any thread safe JDBC drivers? MySQL Connector/J is thread-safe, but even though the JDBC spec states that the driver itself must be thread-safe, most of the API can not be used in a threaded manner. ie, can I open just one connection to the database for a multithreaded servlet? Will the mysql JDBC driver serialize access or allow concurrent statements? Or will I have to worry about synchronization? The driver will serialize access, but you most likely will not want to do that. You will get lower through-put than with multiple connections, and since transactions are mapped to connections, if you ever want to use transactions, you will need to devote one connection per client. You can do this efficiently by using a connection pool, which should be provided by your servlet container. The JDBC API was not really designed to be used in a multi-threaded fashion, so I would avoid it if you can. -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?

My program consists of a father process and n children.
The children do a UPDATE at a certain time and the father might do a
SELECT at the 'same time'.
I suspect strongly that this is the problem. Any ways the father process
hangs at random situations
that involve the children doing UPDATEs and the father SELECT.
I am not sure of this.
What could be the problem?

RE: Using MySQL with Perl 5.8?
Did you remember to allow backwards compatibility in @INC for perl 5.6.1? ~K Black -Original Message- From: Octavian Rasnita [mailto:orasnita;home.ro] Sent: Wednesday, November 13, 2002 2:58 AM To: MySQL List Subject: Using MySQL with Perl 5.8? Hi all, I was able to install the module DBD::mysql for Perl 5.6.1 using ppm (under Windows 2000) but after installing Perl 5.8, ppm can't find this module anymore. I could find only the module DBD::mysqlPP for pure Perl. I don't understand what pure perl means but I've seen that this module accepts less functions than DBD::mysql.

MySQL load problems.
Hello all, I've been having some problems with MySQL crashing. I use a mixture of MyISAM and InnoDB tables, but most of the data is under InnoDB tables. My web applications all do relatively complex join queries. Almost all fields in the WHERE clauses of queries are indexed. I'm running RedHat 7.2, and MySQL version is 3.23.53a The server is: PIII-866 Mhz, 512 MB RAM 18 GIG SCSI drive (no RAID). The server acts as an Apache server AND as a MySQL server The server seems to work fine and has +- an uptime load of 1 - 1.5 when MySQL is running arround 20 queries/sec When it reaches about 30-40 queries/sec, the machine goes to 3-5 load in uptime, often registers slow queries, and eventually dies without any error messages (except that the socket file doesn't exist - i.e. crash). How should I set my memory usage in my.cnf I have a hard time understanding how MySQL works with memory, how it manages it, etc. What should I consider when setting my memory settings??? I have included a paste of my.cnf # The MySQL server [mysqld] port= 3306 socket = /tmp/mysql.sock skip-locking set-variable= key_buffer=128M set-variable= max_allowed_packet=1M set-variable= table_cache=256 set-variable= record_buffer=1M set-variable= sort_buffer=1M set-variable= net_buffer_length=16K set-variable= myisam_sort_buffer_size=96M set-variable= thread_cache=8 set-variable= max_connections=500 log-bin server-id = 1 # Uncomment the following if you are using Innobase tables innodb_data_file_path = innodb/ibdata1:1000M:autoextend innodb_data_home_dir = /usr/local/mysql/data/ innodb_log_group_home_dir = /usr/local/mysql/data/innodb innodb_log_arch_dir = /usr/local/mysql/data/innodb set-variable = innodb_mirrored_log_groups=1 set-variable = innodb_log_files_in_group=3 set-variable = innodb_log_file_size=32M set-variable = innodb_log_buffer_size=8M innodb_flush_log_at_trx_commit=1 innodb_log_archive=0 set-variable = innodb_buffer_pool_size=160M set-variable = innodb_additional_mem_pool_size=96M set-variable = innodb_file_io_threads=4 set-variable = innodb_lock_wait_timeout=50 [mysqldump] quick set-variable= max_allowed_packet=128M [mysql] no-auto-rehash [isamchk] set-variable= key_buffer=128M set-variable= sort_buffer=128M set-variable= read_buffer=2M set-variable= write_buffer=2M [myisamchk] set-variable= key_buffer=128M set-variable= sort_buffer=128M set-variable= read_buffer=2M set-variable= write_buffer=2M [mysqlhotcopy] interactive-timeout - 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: Error: tablespace size stored in header
Shakeel, - Original Message - From: Shakeel Sorathia [EMAIL PROTECTED] Newsgroups: mailing.database.mysql Sent: Wednesday, November 13, 2002 9:39 PM Subject: InnoDB: Error: tablespace size stored in header Hi, we're using Innodb here and I just upped the number of datafiles that innodb was using. When I did a show table status I noticed that I didn't get all the space that I had added. When I looked at the error log, I got recieved the following error. InnoDB: Error: tablespace size stored in header is 96 pages, but InnoDB: the sum of data file sizes is 1152000 pages Can anyone help me out here? BTW, we recompiled innodb to use 64kb pages rather then the default of 16kb. Here is the my.cnf we are using... the support for 16 kB pages is not tested. Big pages were used in 2001 to let InnoDB store BLOBs of size up to 30 kB. But when big BLOBs up to 4 GB were implemented, that was no longer needed. I recommend keeping the page size at the default 16 kB. The error message above can occur if mysqld crashes or fails when you add a new data file. Then it may be that the new data file already got created, but the tablespace size in the tablespace header in the first data file was not yet updated. In that case you normally can remove the extra data file and create a new. But in your case this might also be some bug which surfaces because of the 64 kB page size. 96 pages = 60 000 MB 1152000 pages = 72 000 MB Did you add the last 3 data files manually, and did not let InnoDB to create them and write them full? If yes, that explains why the tablespace size in the tablespace header was not updated.

Re: Changing character sets and 'myisamchk -dvv'
At 23:23 -0500 11/12/02, [EMAIL PROTECTED] wrote: The MySQL documentation (4.6.1) says: You can change the character set with the --default-character-set option when you start the server. The character sets available depend on the --with-charset=charset and --with-extra-charsets= list-of-charset | complex | all options to configure, and the character set configuration files listed in `SHAREDIR/charsets/Index'. See section 2.3.3 Typical configure Options. If you change the character set when running MySQL (which may also change the sort order), you must run myisamchk -r -q on all tables. Otherwise, your indexes may not be ordered correctly. I have a MySQL server with databases that need to begin supporting japanese characters. Per the advice cited above, I've shut it down, restarted it with '--with charset=sjis', and run 'myisamchk -r -q' on all tables. All seems well enough. But when I run 'myisamchk -dvv tablename', the 'Character Set' line in the output indicates that the character set for tables created before I added '--with charset=sjis' to the safe_mysqld startup script is still 'latin1', whereas for newly created tables, myisamchk reports the character set is 'sjis'. The fact that the output is different for tables created before and after the change was made suggests to me that I'm over- looking something. When you run myisamchk -r -q, you should also add the --set-character-set=sjis option so that myisamchk knows what character set to use. - 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?

create database not replicated
MySQL folks, I am having a problem with replication. When I create a new database on the master, the CREATE DATABASE command is not shipped to the slave. Subsequent table creation and table updates on the new database on the master are replicated on the slave, but since the new database was not created on the slave, the slave thread hangs. In this example the new database is called zzz. This is what I see in the binary log (via mysqlbinlog): ... # at 18236 #021108 14:06:48 server id 5 Query thread_id=72exec_time=0 error_code=0 use zzz; SET TIMESTAMP=1036782408; create table abc (id int); # at 18289 #021108 14:08:21 server id 5 Query thread_id=72exec_time=0 error_code=0 SET TIMESTAMP=1036782501; insert into abc values (100); # at 18345 #021108 14:11:52 server id 5 Intvar SET INSERT_ID = 4933; # at 18367 #021108 14:11:52 server id 5 Query thread_id=238 exec_time=0 error_code=0 ... Note that there is a use zzz, but no create database zzz. The error from show slave status on the slave is error 'Can't create/write to file './zzz/abc.frm' (Errcode: 2)' on query 'create table abc (id int)' Is this a problem? Feature?

Most stuff snipped. Sorry :)
I drop the Primary Key (and Timestamp) when I use 'load data infile'.
Below is my VB code which I use in Access to import stuff into MySQL.
Maybe someone will find it useful.
The point is that you have to drop the PK before the import, and add it
back later. If you can't do this, because you already have data in the
table and don't want to mess up the PK, then import the data into a tmp
table and then do a 'insert into' command to append it where you want it.

Re: Changing character sets and 'myisamchk -dvv'
At 23:23 -0500 11/12/02, [EMAIL PROTECTED] wrote: The MySQL documentation (4.6.1) says: You can change the character set with the --default-character-set option when you start the server. The character sets available depend on the --with-charset=charset and --with-extra-charsets= list-of-charset | complex | all options to configure, and the character set configuration files listed in `SHAREDIR/charsets/Index'. See section 2.3.3 Typical configure Options. If you change the character set when running MySQL (which may also change the sort order), you must run myisamchk -r -q on all tables. Otherwise, your indexes may not be ordered correctly. I have a MySQL server with databases that need to begin supporting japanese characters. Per the advice cited above, I've shut it down, restartedit with '--with charset=sjis', and run 'myisamchk -r -q' on all tables. All seems well enough. But when I run 'myisamchk -dvv tablename', the 'Character Set' line in the output indicates that the character set for tablescreated before I added '--with charset=sjis' to the safe_mysqld startup scriptis still 'latin1', whereas for newly created tables, myisamchk reports the character set is 'sjis'. The fact that the output is different for tables created before and after the change was made suggests to me that I'm over- looking something. When you run myisamchk -r -q, you should also add the --set-character-set=sjis option so that myisamchk knows what character set to use. Okay, but after 'myisamchk -r -q --set-character-set=sjis table' is run, 'myisamchk -dvv table' still reports the character set of the table as being the old 'latin1', not 'sjis', so I'm still thinking I may need to drop and recreate all my tables.

This is very odd. I know I have all the settings correct and I've tried different users and pw. I'm using default port (3306) and checked that Linux computer really listens on that port. I've also installed the MySQL O DBC driver. But the exact same error-message accours when I try to connect via the ODBC-driver in ASP from the Win2k computer.
