Hi!
As you can see below, SpamAssassin tags messages from the MySQL list as
spam. The main reason that this happens, is:
SPAM: Hit! (3.5 points) URI: URL of page called unsubscribe
That's because:

One slow connection make mysql slow
I use mysql to register data in an accounting system, comunications happen in a 200 Mbit network and database is really fast, so lock situation ( ie delete after a long select ... ) is really fast and does not create problems. When I connect from a dialup connection obviously query take the same time but sending results to me may take 30 seconds. The problem is that mysql locks the table up to the end of the data sending process so other local client can't work. Is this a bug? Are there a logical explanation?

blob problem
hi, I want to insert binary structure into the mysql blob column.

I tried by end = strmov(query,INSERT INTO retry (msisdn, msg) values(); *end++ = '\''; end += mysql_real_escape_string(*sql, end,91984503,11); *end++ = '\''; *end++ = ','; *end++ = '\''; end += mysql_real_escape_string(*sql, end, msg_struct, sizeof(msg_struct)); *end++ = '\''; *end++ = ')'; I have mysql Ver 11.15 Distrib 3.23.41, for pc-linux-gnu (i686). I have included the -lmysqlclient library but it says undefined reference for strmov. What lib do i include for strmov ? Also when the value is inserted into the blob fieldwhat will i see in the table ? binary or hex value ? When i retrieve that field by select msg from retry;.what format will i get the binary data ? Do i need to do any conversion ? Please guide me regarding inserting blob (binary) type and including strmov function.

RE: installation problems on freebsd
I have started all over again on a fresh Freebsd installation. I have all the files in my /usr/local/mysql directory and I run Scripts/mysql_install_db After that I take the following action $ chown -R root /usr/local/mysql $ chgrp -R mysql /usr/local/mysql $ chown -R mysql /usr/local/mysql/data Than something happens that I don't really understand When I run bin/safe_mysqld -user=mysql The daemon starts followed by the message that mysqld ended. This does not seem to happen when I run bin/safe_mysqld . I don't know the difference but the service keeps on running with the latter I have copied support-files/mysql.server to /usr/local/etc/rc.d (the startup directory) but when I reboot I have to start mysqld manual again The ./bin/mysqladmin -p password does not seem to let me update the password.

Installation issues
Dear MySQL, I am installing Mysql for Unix-3.23.49 for sun-solaris2.8-sparc machine. While i am attempting to run the script called mysql_install_db under scripts directory. It throws me the following piece of results and a result no databases were created in mysql/data/mysql as well as mysql/data/test. Please let me know how i will proceed from this error. ld.so.1: ./bin/my_print_defaults: fatal: libz.so.1: open failed: No such file or directory WARNING: The host 'inatp12wks99' could not be looked up with resolveip. This probably means that your libc libraries are not 100 % compatible with this binary MySQL version. The MySQL deamon, mysqld, should work normally with the exception that host name resolving will not work. This means that you should use IP addresses instead of hostnames when specifying MySQL privileges ! Preparing db table Preparing host table Preparing user table Preparing func table Preparing tables_priv table Preparing columns_priv table Installing all prepared tables ld.so.1: ./bin/mysqld: fatal: libpthread.so.1: version `SUNW_1.2' not found (required by file ./bin/mysqld) Killed Installation of grant tables failed! Examine the logs in ./data for more information. You can also try to start the mysqld daemon with: ./bin/mysqld --skip-grant You can use the command line tool ./bin/mysql to connect to the mysql database and look at the grant tables: shell ./bin/mysql -u root mysql mysql show tables Try 'mysqld --help' if you have problems with paths. Using --log gives you a log in ./data that may be helpful. The latest information about MySQL is available on the web at http://www.mysql.com Please consult the MySQL manual section: 'Problems running mysql_install_db', and the manual section that describes problems on your OS. Another information source is the MySQL email archive. Please check all of the above before mailing us! And if you do mail us, you MUST use the ./bin/mysqlbug script!

Access denied irregularities
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1
Hi all, I'm getting intermittent 'Access denied' errors when running a
php script to admin a mysql db. I've looked in the manual but cannot
work out why I can connect in some parts of the script and not in others
Perhaps there is some common 'gotchas' you might let me know about?
Here is the code I use to connect:
function _db_connect() {
if(!$this-link_id) {
$this-link_id=mysql_connect($this-host, $this-user,
$this-pass);
}
if(!$this-link_id) {
return FALSE;
}
$db=mysql_select_db($this-db) or die (can't select db);
return TRUE;
}
Many thanks for any help :-)

This is default behavior for MySQL. It will give a warning, but not an

Re: Performance issues between two servers
Have you checked the network connection? You should be running at full-duplex so you don't get collisions. But more importantly, make sure you aren't getting errors on the line. A poor crimp or pinched wire could really slow things down, especially if you try running at 100MB. Try copying a single large file between APPDEV1/SQLDEV0 and APPDEV1/SQLDEV1. See what the speed difference is. Backgroud: We have a process that runs on a server (APPDEV1) that writes records to a mysql server (SQLDEV0). We attempted to move the databases from SQLDEV0 to SQLDEV1 and have run into some sort of performance bottleneck. The server SQLDEV0 is a Compac server with ~2GB of ram and two processors. The server SQLDEV1 is also a Compac server. It has 4GB of ram and two processors that are a bit faster than the ones in SQLDEV0. One big difference between SQLDEV0 and SQLDEV1 is the version of RedHat. SQLDEV0 is running RedHat 7.2. SQLDEV1 is running an enterprise version of RedHat 7.2 so that it can take advantage of the 4GB of ram. All the table spaces are using Innodb. Problem: The process on APPDEV1 can write records to the box SQLDEV0 about eight time faster than to SQLDEV1. We've looked over the my.sql configurations and they seem to be ok. In fact we adjusted the my.cnf file on SQLDEV1 so that it was identicle to SQLDEV0 but it did not help. The systems are running ~70-95% cpu idle so cpu is not a bottle neck. In testing, raw disk I/O rates are about 50% faster on SQLDEV1 as SQLDEV0. We don't see a bottle neck on I/O. This is the only process using mysql on SQLDEV1. On SQLDEV0 it shares access with several other programs but the box is not very busy. Thoughts? Comments? Criticism?

RE: Every user can access the databases
[snip]
The problem is, I have a server with different MySQL databases from
different people.
User 1 should not access database 2 and user 2 should not access database 1.
What is the easiest way to prevent user 1 to access database 2. I can't get
it right.

http://www.mysql.com/doc/G/R/GRANT.html
GRANT priv_type [(column_list)] [, priv_type [(column_list)] ...]
ON {tbl_name | * | *.* | db_name.*}

[, user_name [IDENTIFIED BY 'password'] ...]
Notice the second line of the query ON {tbl_name | * | *.* | db_name.*},
this is where you set permissions for a given database and/or table.

moving databases question...
I have before me what seems to be a very daunting task to someone with my limited SQL knowledge. I'm upgrading our ad server which runs on MySQL 3.22.32 to a newer machine and MySQL 3.23.39. Right now there are 16GB worth of databases that need to be transferred over, and the old server lacks enough hard disks space to even do a dump on one of those tables. So is there a way I can do a mysqldump directly from the old machine to the new one over the network? And if I can or if I'm offered a better way to do this, will the difference in MySQL version affect anything?

New Release
Hi, The long awaited version 1.0.13 is now available for downloading. The list of changes and new features is too long, so I will give you a short description of what we changed: - New relationship editor ( now it can handle add new, update and delete and shows the SQL statement as an example) - New integrated User Manager (Add, Drop and Change all the privileges) - New Table Editor (Quick Editor, looks like MSAccess table design) - Fixed BLOB/TEXT fields when exporting results - Multiple statements is now back - Created format toolbar in the grid view to help cell formatting - Import Wizard and Import Text Wizard now saves the definitions, and these can be run at any time by clicking on the menu options - PHP-WSG now handles updates - Run External SQL now parses big SQL files - Added option to empty a table - Fixed bugs in the Export Data - Text Editor now uses a RichEdit Control, without size limitation - Added copy function in the Table Manager - Added support for FULLTEXT index - Fixed bug when exporting multiple files to text files - Query Editor now starts with the selected database as default - Added option to Go/ Don't Go full screen when starting - Import Wizard was improved a lot, now it can handles some data types better and it is quite faster for XBase tables - Removed the List View, now DBTools uses the HTML View to show object's data The new version can be download at http://www.dbtools.com.br as also all information about it.

FULLTEXT search pattern syntax
Hi,
It's not quite clear from the manual, but it appears that queries with
FULLTEXT search patterns like this:
MATCH (some_text_field) AGAINST ('(red pepper) (green bean)')
don't produce the result desired, that is, multiple .. elements are not
allowed, with or without parentheses...
Could someone confirm, please?
On a general note, it would be nice to have the formal syntax of FT search
patterns in the manual.
TIA,
Vadim.

Bug or error in SQL syntax - Specifying and using a user variable inside a single select query
Greetings, Upon reading into the user variables section of the mysql manual, I decided to make my life easier inside several of my queries by specifying some user variables. Note that I'm trying to have everything inside the select statement - Primarily because I'm simply passing it through to my data mining software that interfaces through myODBC. I'm trying to accomplish the following query (I'm executing these sql queries directly from the command line) -- == SELECT annual_filing.*, companies.name AS company_name, YEAR(filing_date) AS filing_year, (@predictedYear := 1999) AS predictedYear, (@earliestYear := 1996) AS earliestYear, (@learnYear := 1998) AS learnYear FROM annual_filing, companies WHERE annual_filing.company_id = companies.ds_id AND YEAR(filing_date) = @predictedYear AND YEAR(filing_date) = @earliestYear; == The above query returned an empty set / no rows. Replacing the user variables with actual values, as shown below, returns the appropriate rows (5537 rows) (for obvious reasons because I'm not using any user variables in the WHERE clause): == SELECT annual_filing.*, companies.name AS company_name, YEAR(filing_date) AS filing_year, (@predictedYear := 1999) AS predictedYear, (@earliestYear := 1996) AS earliestYear, (@learnYear := 1998) AS learnYear FROM annual_filing, companies WHERE annual_filing.company_id = companies.ds_id AND YEAR(filing_date) = 1999 AND YEAR(filing_date) = 1996; == I also tried the below ... == SET @predictedYear = 1999; SET @earliestYear = 1996; SET @learnYear = 1998; SELECT company_id, @findEarliestYear AS findEarliestYear, @findLearnYear AS findLearnYear, @findPredictedYear AS findPredictedYear FROM annual_filing WHERE YEAR(annual_filing.filing_date) @findPredictedYear; == And mysql returned no results / an empty set. Trying to debug the problem further, I tried ... == SET @predictedYear = 1999; SET @earliestYear = 1996; SET @learnYear = 1998; SELECT company_id, @findEarliestYear, @findLearnYear, @findPredictedYear FROM annual_filing WHERE YEAR(annual_filing.filing_date) @findPredictedYear; == Still an empty set... And also verified the SET is actually doing its job (which it is) -- == mysql SET @predictedYear = 1999; Query OK, 0 rows affected (0.00 sec) mysql SET @earliestYear = 1996; Query OK, 0 rows affected (0.01 sec) mysql SET @learnYear = 1998; Query OK, 0 rows affected (0.00 sec) mysql SELECT @predictedYear, @earliestYear, @learnYear; ++---++ | @predictedYear | @earliestYear | @learnYear | ++---++ | 1999 | 1996 | 1998 | ++---++ 1 row in set (0.00 sec) == Does anyone have any insights or clues as to what the problem could be?

Could you explain, what result is desired and what result you are getting ?
Because, right now I can only say that multiple .. elements ARE
allowed, of course.

There is a list of operators, you can use any of them in whatever

If you have MySQL 4, you can use a UNION. Otherwise you'll need a second table, because what you want is not a join, but a concatenation of result sets.

Converting text files to MySQL
I've been trying to import text files into MySQL, but I can't get it to work. I'm new to MySQL and am still getting familiar with it, so perhaps I'm missing something. I'm using the LOAD DATA LOCAL command but I keep getting error 1148 The used command is not allowed with this MySQL version. Now from reading the information in the docs section (http://www.mysql.com/doc/L/O/LOAD_DATA_LOCAL.html) it appears that LOAD DATA LOCAL is sometimes disabled for security reasons, and that there are two ways around this. I've tried both ways but it doesn't seem to work. I tried using the command --enable-local-infile but apparently that's only compatible with version 3.23.48 and before, and we have 3.23.49. Is there something else I should do? Can anyone help me please? Thanks so much! Christy Roberts Technical Project Lead iMIRADOR.com Inc.

High-Speed/Volume Database
We are designing an application that needs to use a relational database to hold quite a large amount of data. In particular there is one table that has about 33 fields, 18 indexes, and 120 bytes per record. Additionally, we are going to need to add about 2 million records per day to the table, delete about 2 million records per day from the table, hold 2 weeks worth of data within the database (approx. 30 million records), and sustain an average add rate of about 23 records per second while, at the same time, sustaining an average delete rate of 23 records per second.

Re: High-Speed/Volume Database
Over here, we're doing an average of 95 queries per second (that's about 8 mill daily), on a Pentium III @ 900MHz with 768MB of ram. We're working with smaller data sets, than 30 million records, tho. I imagine that you could do well with a high end intel system, or a medium-end Sun box. A dual processor Athlon MP 1900+ system with 4GB of ram, and SCSI raid would probably serve you well. This would run about $5k at most. If you want to go with sun, a E450 would probably do the trick for ya. Figure 8GB of ram (more ram is good -- the more of the DB you can hold in memory, the better you'll do.) and 2 or 4 processors. (Actually, I suspect than an E450 would exceed your needs by a lot.) That sort of box would cost you about $20k, IIRC. HTH, Gabriel.

Re: Get the next AUTO INCREMENT value for a column
To the originator of this thread: While what you are asking is possible, Id like to put my two cents in and ask you please not to do it. If this is a production database, you have no idea how helpful it will be for you to know by those missing pk numbers that something was deleted manually from the database as opposed to an index error, or some other more disasterous problem. In my experiece leave those holes in the pk sequence, and then later on when someone complains that a record is missing, you can say with some confidence that someone actually deleted it. AS a followup note, I would never allow user permissions to let a regular user delete a record in the first place, and I would stop it with either code, or database user access privelages. Instead create an active/inactive status field and then you can rewrite some code to add a where status = 'active' or similar line of code Then create a purge records' function in your app so that admins who are supposed to know what they are doing can delete records if they really want to.

My questions are, what database software should we use, what kind of hardware platform will be needed to support the specifications enumerated above, and what kind of average query performance can we expect? Bob, You left out some critical information. 1a) How many concurrent users will there be reading from the busiest table, and 1b) how many will be deleting records from the busiest table? 2) Also how do you determine which records will be deleted? Do you delete an entire days worth of records at a time? If so, you might consider creating a table for each day, like table_mon, table_tue, ... table_sun, table_lastmon, ... table_lastsun so you have 14 tables. When you get a new day, you do a Delete * from table_mon (if it is Monday) which in effect drops the table and recreates it which is extremely fast. To query the entire set of tables, use Merge tables. This only works with MyISAM tables. If on the other hand you need to add and delete records concurrently, try InnoDb table type. It stands up well to deletes and inserts. One suggest I have is to use CHAR() field types rather than VarChar(). If you delete fixed length records (CHAR) then MySQL can re-use the deleted space. VarChar will have internal fragmentation especially when doing all those deletes, so eventually you will need to reload the data. So stick with CHAR if you can. You will need at least dual processors and stuff it with as much RAM as it can hold (2g or more).

My hosting service folks are telling me that I should only update my database on their server via update transactions. They say this is for security reasons. UltraDev provides many good tools for viewing, adding, updating and deleting records for the database but I'm not sure how to produce add/delete/update transactions from UltraDev and I'm not convinced it is necessary to have the added layer of security. Is this standard operating procedure when making changes to mySQL databases or should I tell them that I want direct access to my database? Any help/suggestions/guidelines in this area would be very helpful. Thanks.

RE: Two database servers, same physical server
Hi, To run multiple mysqld servers, you at least have to specify a different port number, different socket file path, different pid and error log file to get it started. Different mysqld servers may point to the same database. To do this, just define the necessary information for your new mysqld server in a my.cnf file, and start it with ./bin/safe_mysqld --defaults-file=/path/to/new/my.cnf .

RE: Two database servers, same physical server
Hi If the databases are not too big, and are on the same machine, you could just copy the directory with the databases in. If you need to restore the database just copy it back. I think this is OK, though you might want to stop mysql to lock the database. I have only done this a couple of times (on a quiet database) because I replicate across two servers. If anybody knows better, or thinks this is a bad idea, then I will defer to their greater knowledge!

Hi,
It's not quite clear from the manual, but it appears that queries with
FULLTEXT search patterns like this:
MATCH (some_text_field) AGAINST ('(red pepper) (green bean)')
don't produce the result desired, that is, multiple .. elements are not
allowed, with or without parentheses...
Could you explain, what result is desired and what result you are getting ?
Because, right now I can only say that multiple .. elements ARE
allowed, of course.
On a general note, it would be nice to have the formal syntax of FT search
patterns in the manual.
I do not understand, what is missing in the manual right now ?
There is a list of operators, you can use any of them in whatever
combination you want.

Re: Bug or error in SQL syntax - Specifying and using a user variable inside a single select query

You should first initialize user variables! By default they contain
NULL values as SELECT works by first checking WHERE clause and only then
works
for SELECT.
Check the manual:
http://www.mysql.com/doc/V/a/Variables.html
According to the manual from the above link, where it states:
==
You can set a variable with the SET syntax:
SET @variable= { integer expression | real expression | string expression }
[,@variable= ...].
You can also assign a value to a variable in statements other than SET.
However, in this case the assignment operator is := rather than =, because =
is reserved for comparisons in non-SET statements:
mysql SELECT @t1:=(@t2:=1)+@t3:=4,@t1,@t2,@t3;
+--+--+--+--+
| @t1:=(@t2:=1)+@t3:=4 | @t1 | @t2 | @t3 |
+--+--+--+--+
|5 |5 |1 |4 |
+--+--+--+--+
==
mysql should be SET'ing the user variables in my query above. If mysql is
processing the WHERE first and then the SELECT, shouldn't the user variables
be set anyhow (even if the query returns an empty set)? For example:
==
mysql SELECT
-annual_filing.*,
-companies.name AS company_name,
-YEAR(filing_date) AS filing_year,
-@predictedYear := 1999 AS predictedYear,
-@earliestYear := 1996 AS earliestYear,
-@learnYear := 1998 AS learnYear
- FROM
-annual_filing,
-companies
- WHERE
- annual_filing.company_id = companies.ds_id
-AND
- YEAR(filing_date) = @predictedYear
-AND
- YEAR(filing_date) = @earliestYear;
Empty set (25.89 sec)
mysql SELECT @predictedYear, @earliestYear, @learnYear;
++---++
| @predictedYear | @earliestYear | @learnYear |
++---++
| NULL | NULL | NULL |
++---++
1 row in set (0.00 sec)
==
If I execute a separate SELECT statement beforehand (Or SET for that matter)
setting the user variables then it works. However, I'm trying to use MyODBC
to connect into the server with my data mining software and I can't perform
multiple queries in this fashion (it expects me to only send one query).
:( Perhaps there's a workaround?

re: setting up innodb
I am running mysql on solaris. This is a binary release. However, now I would like to start my server with the innodb functionality. But I can't start my server working for this. I am not able to run the ./configure --with-innodb I dont know how and where innodb_data_file_path should be specified I can't open the mysqld file to add the pathtodatafile Where am I suppose to set the variables at the startup(of mysql) Does someone have step by step process in mind that I can follow. Help would be extremely helpful.

You can see what yours is set to with SHOW VARIABLES command.

slow queries/ db performance
Under normal operating conditions our v3.23.47 MySql db server handles about 60 queries per second using 50 threads or less. The host is a dual processor 700MHz Intel machine running the 2.2.14-5.0smp Linux kernel with 256M of RAM. Here's the problem: during spikes of activity where about 90-100 queries/sec are being processed, the number of slow queries ties up an ever-increasing number of threads until our max connection limit is reached. This eventually will cause clients to wait for an inactive thread which effectively freezes our application. The slow query SQL statements are optimized - usually they take .5 sec (~10-20K rows being examined), but when the server is in this state execution time ranges from 10-120 seconds. Questions: 1. Are an abundance of slow queries symptomatic of an overloaded DB server? (or are they simply a contributing factor?) 2. Is there a way to examine the state of a slow query besides the slow-query log? I.e. is there a way to tell exactly why a query is running slow? Running explain shows our SQL to be as optimized as it can get. 1. I've read threads in this group about similar server configurations handling 200 queries/sec. What are the most effective ways of benchmarking a server against an application? I've included the MySql setting below.

Maximum number of rows in the table
Hi MySql gurus, We are using MySql for our database support in our project. It is a multiserver environment. We are using a single table to store info abt objects of each server. We want to know what is the maximum number of rows that the MySql supports for a table. In our case when the number of rows exceeds 1500 the server crashes. Is it the max number of rows ? with regards, Chandrashekar B.N. - 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?
