RPM Install appears to have failed
RedHat6.2 install (everything) out of box on Intel 1 proc server 256mb ram. Downloaded 3.23.52-1 rpm client rpm to /usr/loca/tmp - i created the tmp folder as root and chmod 777 Followed the install instructions - which only included: To perform a standard minimal installation, run: shell rpm -i MySQL-VERSION.i386.rpm MySQL-client-VERSION.i386.rpm (No user or group or environment setup instructions before running rpm's???) So logged in as root I executed the following, and got the result below [root@plinux tmp]# rpm -i MySQL-Max-3.23.52-1.i386.rpm MySQL-client-3.23.52-1.i386.rpm Giving mysqld a couple of seconds to restart var/tmp/rpm-tmp.10346: /etc/rc.d/init.d/mysql: No such file or directory Was this successful? Where did mysql install to? The post installation steps say to: shell ./scripts/mysql_install_db shell cd mysql_installation_directory shell ./bin/safe_mysqld --user=mysql cd_mysql_installation_directory - where the heck did it install at? don't think this happened... thanks in advance.

lotus decs problem with myodbc
Hello I'm trying to connect a Lotus Server through DECS, to a MySQL db. The Lotus and the MySQL servers are installed on the same linux machine. I installed iodbc, myodbc, successfully tested them with odbctest from Linux, and with ndctest (or smth like that) from a Windows system. Anyway, I'm trying to configure the Decs server from a Windows client, with Notes Administrator, but without any luck. The standard error message when I'm trying to select the tables is: Unable to browse ODBC Oh yea, I also installed the myodbc driver on the Windows system I'm running the NotesAdmin from. Any ideas?

Re: MySQL/InnoDB-4.0.4 is released
Hi,
You have right, in the new version (4.0.4) on Windows 9x are the same
symptom.
I research a little in this morning and i found where is the problem when
the innodb is initialised.
The problems is in the function:
sync_array_create()
...when it must initialise a lot of cells(n_cells=aprox. 6.000.000).
The routine is next :
for (i = 0; i n_cells; i++) {
cell = sync_array_get_nth_cell(arr, i);
cell-wait_object = NULL;
/* Create an operating system event semaphore with no name
*/
cell-event = os_event_create(NULL);
cell-event_set = FALSE; /* it is created in reset state */
}
The configuration of my computer for testing is:
CPU : INTEL P IV/1,7 Ghz
RAM: 512 MB DDRAM
HDD: 2x40 GB(IDE)
OS:Windows 98 OSR2
Maybe this help on Heikki to see what happend.

Gelu

Re: Need Driver to connect Unix SCO 5.2 Open Server to MySQL DB?
You keep bringing up ODBC like it is some magic charm. Why do you think you need ODBC? Does your client software require it? You have not told us what the client is, or what it is written in. The 'mysql' client on any platform talks natively to the 'mysqld' server on any platform. PHP does not need ODBC. Perl does not need ODBC. VB can use libraries other than ODBC. Chris Couture wrote: Thanks again for the help! I tried this on my local machine and it worked like a champ.

RE: Need Driver to connect Unix SCO 5.2 Open Server to MySQL DB?
Dean, Thanks for you reply. You are almost correct in our system layout but the MySQL database server is on a seperate machine (currently running Windows 2000 AS with all the databases on a separate drive and soon to be updated to Linux). The inserts would need to take place over the network to the MySQL server, which from what Gerald has helped me with, seems like we only need to put the hostname in when we call the MySQL server verses having it insert locally. This still leaves one real question and that is, which client do I need to use on the SCO 5.2 machine? If we install the older 3.2 (already compiled) version of MySQL on the UNIX machine, can it talk to the newer 4.** server located on the other machine. It's going to complete a simple insert statement. If not, I guess we will need to compile our own. As far as the programming language that the UNIX is using, I will have to talk to my UNIX programmer. The Windows machines used for processing the shipments work just right using the MyODBC connection. I have converted our old Access databases over to MySQL and everything works like a dream there. It's just a matter of getting the UNIX machine that processes all of our orders to dump the data to the MySQL database instead of inserting it into the text file so that everything is tied together. Thanks again, Chris -Original Message- From: Grimes, Dean [mailto:[EMAIL PROTECTED]] Sent: Thursday, October 03, 2002 8:01 AM To: Chris Couture Subject: RE: Need Driver to connect Unix SCO 5.2 Open Server to MySQL DB? Chris, If I understood you correctly, you have a Unix server that creates text string when an invoice is processed. That string of data is to be inserted into the MySQL database. Then you have a Windows application that needs to be able to retrieve that data from the MySQL database that resides on the Unix server. If that is stated correctly, then I am assuming that MySQL and the invoice processor are running on the same Unix server. If that is the case, it should be easy enough for your programmer to insert that data directly into MySQL. There are a couple of different methods that will work. 1. You could write a shell script that your invoice processor would call each time a record needs to be inserted. The data would be passed as parameters to the shell script. The shell script would use the MySQL client to perform the insert. There is some overhead associated with this method but you are only inserting about 2500 records a month. Which translates to only 84 inserts a day. This is very low traffic and your system should handle it no problem. Example script: #!/bin/ksh # Insert into mysql database mysql -s % insert into table_name (col1,col2,col3,col4) values($1,$2,$3,$4); % This script is not checking for any errors. The completion status should be returned to the calling program for obvious reasons. Of course this assumes that the user_id that the invoice processing program is running as has grants in the mysql.user table with insert privileges. The invoice processing program would have a system call like: system(/path/to/script/insert_to_mysql arg1 arg2 arg3 arg4) or some such call as that. That is the easiest method to putting data into mysql. 2. Depending on the language your invoice processor is written in, you could talk directly to MySQL. This is the preferred method. I would need more information about your invoice processing program to more accurately provide examples. As to your Windows app. MyODBC works just fine. We use it here and have had no problems with it. ODBC is going to be slower than a direct connect, but again we're talking a very low amount of traffic. You should have no problems.

I run the following query from a php script - select d1.code, d1.type, d1.descr, d1.grouptype, d1.cusref, d1.stock, d1.minstock, d1.appmeth, d1.supplier, d1.suppref, d1.leadtime, d1.price, d1.reorder, d1.code1, d1.code2, d1.notes, d1.usr, d1.usr, d1.cusname, d1.colours, d1.stitchcount, d1.height, d1.width, DATE_FORMAT(d1.created, '%d-%m-%Y'), DATE_FORMAT(d1.amended, '%d-%m-%Y'), d2.extdescr from decheader as d1, decextdescr as d2 where d1.code = d2.code and d1.code = '00042' The problem I am having is with the DATE_FORMAT. Running the above query returns the following for the width column. 94.40 DATE_FORMAT(d1.created, '%d-%m-%Y'): NULL DATE_FORMAT(d1.amended, '%d-%m-%Y'): 03-10-2002 The width column should only return 94.40.

I have a slow query that needs optimising..
Hi all,
I wonder if anyone could help me speed up the following query (it works fine
and produces the result I want but it's very slow...)
Here is a typical query (will be executed quite often on a reasonably busy
system (about 50% idle doing other stuff that is not using the below
tables..)):
select count(*) as num,publicinfo.*,if
(local_classes.cat='hot','checked','') as checked,local_classes.* from
publicinfo, local_classes where local_classes.class_code =
publicinfo.class_code and x507000 and x547000 and y164500 and y204500
group by cat;
This is running very slowly on Redhat 7.2, MySQL 3.23 binary install, a twin
1GHz Xeon compaq ML530, 1GB Ram, SCSI disk etc... (it's not swapping and
the disk servicetime is OK)
Can anyone come up with a touch of magic to make this query more efficient?
(table definitions below...)
There are 2 tables:
1. 'publicinfo' (Just under 800,000 records):
CREATE TABLE publicinfo (
id mediumint(9) NOT NULL auto_increment,
seq int(11) NOT NULL default '0',
name varchar(50) NOT NULL default '',
pc varchar(10) NOT NULL default '',
host varchar(120) NOT NULL default '',
path varchar(120) NOT NULL default '',
url varchar(120) NOT NULL default '',
class_code
enum('h','rp','rs','mv','www','pub','gc','res','cin','ind','hot','des','loc'
,'tube','cam') default NULL,
x mediumint(9) NOT NULL default '0',
y mediumint(9) NOT NULL default '0',
supplier varchar(10) NOT NULL default 'mm',
PRIMARY KEY (id),
KEY cat_idx (class_code),
KEY geo_idx (x,y)
) TYPE=MyISAM;
2. 'local_classes' (about 1000 records)
CREATE TABLE local_classes (
class_code varchar(40) NOT NULL default '',
name varchar(30) NOT NULL default '',
cat varchar(20) NOT NULL default '',
label varchar(25) NOT NULL default '',
KEY class_idx (class_code),
KEY cat_idx (cat),
KEY idx1 (class_code,cat)
) TYPE=MyISAM;

Hi,
You have right, in the new version (4.0.4) on Windows 9x are the same
symptom.
I research a little in this morning and i found where is the problem when
the innodb is initialised.
The problems is in the function:
sync_array_create()
...when it must initialise a lot of cells(n_cells=aprox. 6.000.000).
that number is strange. It should be 10 000. Maybe you have compiled with
optimizations so that the debugger shows a wrong number.
But this reveals a possible reason for the slowness and other problems in
Win 95/98/ME.
Can you try the following: in
\mysql\innobase\include\os0thread.h
change
#define OS_THREAD_MAX_N 1
to a smaller value, for example, 100.
It may be that Win 95/98/ME has problems in creating a large number of event
semaphores.
You have to recompile the 'innobase' project because the change is in a
header.
Please report if this helps.
Regards,
Heikki

The routine is next :
for (i = 0; i n_cells; i++) {

cell-wait_object = NULL;
/* Create an operating system event semaphore with no name
*/
cell-event = os_event_create(NULL);
cell-event_set = FALSE; /* it is created in reset state */
}

Will the bugfixes for this release (not necessarily the new/updated

use 3.23.x.
of course, the fix will be backported if the bug also existed in 3.23.
The DESC bugs in 4.0.x are not present in 3.23.
Since 4.0.x releases will come in more rapid succession than 3.23

it may soon be that the most bug-free InnoDB is actually in the latest
4.0.x.

InnoDB hard lockup
Hi All, First thanks to all who worked on InnoDB, it is truely exciting to get its features in an open-source DB. We've had an excellent experience thus far with a few exceptions. Any help on solving the problem below is greatly appreciated ... We experienced a hard lockup a few days ago with mysql-max-3.23.52 for Solaris 2.7. The DB had been running very well for over a month until the innodb_monitor was turned on. After turning it on, all InnoDB threads blocked within a few minutes, and we saw the messages below in the error log. The only other info that may seem relevent is that we have a monitor that executes show table status every 15 minutes to check for remaining space in the InnoDB tablespace. That monitor does not run in our test environment and we never had a problem with the innodb monitor in our test environment while executing a similar workload. So this problem may be correlated or caused by the show table status command in conjunction with the innodb monitor. Any thoughts? ... end of innodb monitor output removed ... -- ROW OPERATIONS -- 5 queries inside InnoDB, 0 queries in queue; main thread: doing background drop tables Number of rows inserted 9070335, updated 3286308, deleted 1038094, read 536669195 11.52 inserts/s, 14.80 updates/s, 8.40 deletes/s, 393.73 reads/s END OF INNODB MONITOR OUTPUT InnoDB: Warning: a long semaphore wait: --Thread 75521 has waited at trx0trx.c line 576 for 242.00 seconds the semaphore: Mutex at 1c12938 created file srv0srv.c line 1621, lock var 1 Last time reserved in file lock0lock.c line 341, waiters flag 1 InnoDB: Warning: a long semaphore wait: --Thread 75832 has waited at lock0lock.c line 341 for 242.00 seconds the semaphore: Mutex at 1c12938 created file srv0srv.c line 1621, lock var 1 Last time reserved in file lock0lock.c line 341, waiters flag 1 InnoDB: Warning: a long semaphore wait: --Thread 74124 has waited at trx0trx.c line 576 for 242.00 seconds the semaphore: Mutex at 1c12938 created file srv0srv.c line 1621, lock var 1 Last time reserved in file lock0lock.c line 341, waiters flag 1 ... lots more like this, and then ...

Re: Perl with Mysql
HI all
I'm trying to do the following
---
# want to select (just preparing) every thing from the table PERSON
where i don't know the deptID yet.
$per = $dbh-prepare(SELECT * FROM person WHERE deptID = ?);
# selecting deptID from the table ACCOUNT, say with some condition
$acc = $dbh-prepare(SELECT deptID FROM account WHERE ;
$acc-execute()
or die Can't execute the SQL statment: $DBI::errstr\n;
while ( @accRow = $acc-fetchrow_array ) {
# For each deptID I get from the ACCOUNT table, I want all the info from
the PERSON table
$per-execute($accRow[0] )
or die Can't execute the SQL statment:
$DBI::errstr\n;
The statements above are all part of a subroutine, and not meant to be
executed as individual commands. Here's what is on the page you
referenced:
sub age_by_id
{
# Arguments: database handle, person ID number
my ($dbh, $id) = @_;
my $sth = $dbh-prepare('SELECT age FROM people WHERE id = ?')
or die Couldn't prepare statement: . $dbh-errstr;
$sth-execute($id)
or die Couldn't execute statement: . $sth-errstr;
my ($age) = $sth-fetchrow_array();
return $age;
}
You have to pass this subroutine 2 arguments when you execute it: $dbh
and $id before it will work.

Re: MySQL/InnoDB-4.0.4 is released
Hi!
I believe the following patch fixes the startup problems on Win 95/98/ME in
InnoDB versions which have been released after July 2, 2002.
Looks like Win XP can easily create 40 000 event semaphores, but for
95/98/ME it is too much.
This should be in upcoming MySQL-3.23.53 and MySQL-4.0.5.
Thank you for the bug reports.

Hi,
You have right, in the new version (4.0.4) on Windows 9x are the same
symptom.
I research a little in this morning and i found where is the problem
when
the innodb is initialised.
The problems is in the function:
sync_array_create()
...when it must initialise a lot of cells(n_cells=aprox. 6.000.000).
that number is strange. It should be 10 000. Maybe you have compiled with
optimizations so that the debugger shows a wrong number.
But this reveals a possible reason for the slowness and other problems in
Win 95/98/ME.
Can you try the following: in
\mysql\innobase\include\os0thread.h
change
#define OS_THREAD_MAX_N 1
to a smaller value, for example, 100.
It may be that Win 95/98/ME has problems in creating a large number of
event
semaphores.
You have to recompile the 'innobase' project because the change is in a
header.
Please report if this helps.

Will the bugfixes for this release (not necessarily the
new/updated
features) be backported to the 3.23.x series? Given that MySQL 4
isn't marked as stable yet, many of us using InnoDB no doubt still
use 3.23.x.
of course, the fix will be backported if the bug also existed in
3.23.
The DESC bugs in 4.0.x are not present in 3.23.
Since 4.0.x releases will come in more rapid succession than 3.23
releases,
it may soon be that the most bug-free InnoDB is actually in the
latest
4.0.x.

If you just reply to this message, and include the entire text of it in the reply, your reply will go through. However, you should first review the text of the message to make sure it has something to do with MySQL. Just typing the word MySQL once will be sufficient, for example. You have written the following: Is there a way to get a more detailed explain statement? If not, maybe someone can answer this for me. Say I have a statement like this: EXPLAIN SELECT /*! STRAIGHT_JOIN */ t1.* FROM table2 t2 INNER JOIN table1 t1 /*!

Is it going to join t1, t2, and t3, find the fields that match on keys, and then sift out the rows that don't pass the MOD() or is it going to join t2 - t1, sift out the MOD() entries, then join t3 into the mix on the remaining rows? sql, query * Philip Molter * Texas.net Internet * http://www.texas.net/ * [EMAIL PROTECTED] - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

Re: InnoDB hard lockup
Wayne, please send me the whole MySQL error log. Looks like some thread, which had reserved the InnoDB 'kernel' mutex to access the InnoDB lock table, got stuck. This is interesting: 5 queries inside InnoDB, 0 queries in queue; main thread: doing background drop tables If you drop a table where there still are queries running, then InnoDB delays the drop table until the queries have ended, and only after that drops the table. When dropping the table, InnoDB has to remove also any locks there are on the table. The code is not that well tested. The bug might be there. What DROP TABLE and what queries could have been involved? Do you have very many tables? Does SHOW TABLE STATUS take long? Are you sure you ran innodb_monitor and not innodb_lock_monitor? Can you repeat the bug?

Subject: InnoDB hard lockup From: Wayne Lewis Date: Thu, 3 Oct 2002 08:48:26 -0700 Hi All, First thanks to all who worked on InnoDB, it is truely exciting to get its features in an open-source DB. We've had an excellent experience thus far with a few exceptions. Any help on solving the problem below is greatly appreciated ... We experienced a hard lockup a few days ago with mysql-max-3.23.52 for Solaris 2.7. The DB had been running very well for over a month until the innodb_monitor was turned on. After turning it on, all InnoDB threads blocked within a few minutes, and we saw the messages below in the error log. The only other info that may seem relevent is that we have a monitor that executes show table status every 15 minutes to check for remaining space in the InnoDB tablespace. That monitor does not run in our test environment and we never had a problem with the innodb monitor in our test environment while executing a similar workload. So this problem may be correlated or caused by the show table status command in conjunction with the innodb monitor.

As for why have you been actively avoiding ODBC .. well..mainly portability reasons. I like to secretly hope one day my boss lets me migrate to Solaris or *BSD .

Re: Is there Examples and Documents on joining tables?
Hi Arthur, Thanks for your answer and your example. Your example is very good but I can't map to what I'm trying to do. As you suggested I have to understand how inner join is implemented in MySQL. The query that I'm working on selects fields from three tables, in this way, Table_1 has columns A,B,C supplies fields ( A,B, C) Table_2 has columns A,T,U supplies fields (T,U) Table_3 has columns A,B,C,X,Y,Z supplies fields (X,Y,Z) Table_1 and table_2 have a strange relationship with each other, one row in table_3 could match with a number of rows in table_1 if table_1.A = table_3.A and table_1.B=table_3.B and (table_1.C=table_3.C or table_3.C = *). That's what I can't get to work. I worked on this on MSSQL and wrote a query that does the above but I cannot find the equivalent query for it in MySQL. For I've split the query in two parts and put the results back together in my application. But I would look at DBTools and see if I can learn something from it. Thanks again for you advice.

Re: Is there Examples and Documents on joining tables?
Yes there are. First do as you have written, although your syntax is a bit wrong but the email compiler forgives such stuff :-) SELECT table1.bunch, table2.of, table3.stuff FROM table1 INNER JOIN table2 ON table2.some_id INNER JOIN table3 ON table3.some_id WHERE table1.some_id = table2.some_id AND table1.some_id = table3.some_id; should have been: SELECT table1.bunch, table2.of, table3.stuff FROM table1 INNER JOIN table2 ON table2.some_id = table1.FK INNER JOIN table3 ON table3.some_id = table1.FK WHERE table1.some_id = table2.some_id AND table1.some_id = table3.some_id; IMO you confuse the logic if you combine joins with wheres. You make it very hard to understand what's occurring and even harder to debug it. Store all your join logic in the join clauses, then reserve the where for precisely what you mean. For example: SELECT Table1.Stuff INNER JOIN Table2 ON Table1.FK = Table2.PK INNER JOIN Table3 ON Table2.FK = Table3.PK (etc.) WHERE Table1.PK = myVar In this sort of construction, the logic is far more apparent than in a construction which blurs the joins and wheres. Just my $.02.

Re: InnoDB hard lockup
Wayne,
the bug found and fixed.
If SHOW INNODB STATUS or innodb_monitor printed several hundred
transactions, and the output was truncated, it forgot to release the
'kernel' mutex, causing the hang.
Also the main thread was hung. That is why it claimed to be doing a
background table drop.
The bug will be fixed in 3.23.53 and 4.0.5. Until then do not use SHOW
INNODB STATUS, innodb_monitor, or innodb_lock_monitor if you have hundreds
of concurrent connections to the server.
Thank you for the detailed bug report,

Subject: Re: InnoDB hard lockup
Wayne,
please send me the whole MySQL error log.
Looks like some thread, which had reserved the InnoDB 'kernel' mutex to
access the InnoDB lock table, got stuck.
This is interesting:
5 queries inside InnoDB, 0 queries in queue; main thread: doing background
drop tables
If you drop a table where there still are queries running, then InnoDB
delays the drop table until the queries have ended, and only after that
drops the table. When dropping the table, InnoDB has to remove also any
locks there are on the table. The code is not that well tested. The bug
might be there.
What DROP TABLE and what queries could have been involved?
Do you have very many tables?
Does SHOW TABLE STATUS take long?
Are you sure you ran innodb_monitor and not innodb_lock_monitor?
Can you repeat the bug?
Best regards,

Hi All,
First thanks to all who worked on InnoDB, it is truely exciting to get its
features in an open-source DB. We've had an excellent experience thus far
with a few exceptions. Any help on solving the problem below is greatly
appreciated ...
We experienced a hard lockup a few days ago with mysql-max-3.23.52 for
Solaris 2.7. The DB had been running very well for over a month until the
innodb_monitor was turned on. After turning it on, all InnoDB threads
blocked within a few minutes, and we saw the messages below in the error
log.
The only other info that may seem relevent is that we have a monitor that
executes show table status every 15 minutes to check for remaining space
in the InnoDB tablespace. That monitor does not run in our test
environment
and we never had a problem with the innodb monitor in our test environment
while executing a similar workload. So this problem may be correlated or
caused by the show table status command in conjunction with the innodb
monitor.
Any thoughts?

Multi-table Join (WAS: Is there Examples and Documents on joining tables?)
Here is the query that I had in a PhP script that joins a bunch of tables (I'll try to make this look readable). If you're curious, it's for a motorcross site (www.springcreekmx.com): SELECT standings.rank, race.race_date, class.class_name, racer.racer_name, cycle.cycle_desc, race_event.racer_id, race_event.points_earned, race_event.racing_number, race_event.overall_rank, race_event.round, standings.total_points FROM race_event INNER JOIN racer ON racer.racer_id INNER JOIN standings ON standings.racer_id INNER JOIN race ON race.round INNER JOIN class ON class.class_id INNER JOIN cycle ON cycle.cycle_id WHERE race_event.racing_cycle = cycle.cycle_id AND race_event.class_id = class.class_id AND race.round = race_event.round AND race.series_id = race_event.series_id AND race.class_id = race_event.class_id AND standings.racer_id = racer.racer_id AND standings.class_id = race_event.class_id AND standings.series_id = race_event.series_id AND race_event.racer_id = racer.racer_id AND race_event.class_id = '2' ORDER BY rank, race_date; This syntax actually works, from the posts it sounds like I might be getting away with one. So, from the posts regarding table joins, this would be correctly written as: SELECT standings.rank, race.race_date, class.class_name, racer.racer_name, cycle.cycle_desc, race_event.racer_id, race_event.points_earned, race_event.racing_number, race_event.overall_rank, race_event.round, standings.total_points FROM race_event INNER JOIN racer ON racer.racer_id = race_event.racer_id INNER JOIN standings ON standings.racer_id = racer.racer_id AND standings.class_id = race_event.class_id AND standings.series_id = race_event.series_id INNER JOIN race ON race.round = race_event.round AND race.series_id = race_event.series_id AND race.class_id = race_event.class_id INNER JOIN class ON class.class_id = race_event.class_id INNER JOIN cycle ON cycle.cycle_id = race_event.racing_cycle WHERE race_event.class_id = '$class_search' ORDER BY rank, race_date; Looks much nicer, doesn't seem to be a dramatic increase in performance, but I think it makes more sense this way. Does this look ok? The size of tables (smallest to largest) is series, cycle, class, race, racer, standings, race_event. I re-ordered the INNER JOINS to join on the smallest table like so: SELECT standings.rank, race.race_date, class.class_name, racer.racer_name, cycle.cycle_desc, race_event.racer_id, race_event.points_earned, race_event.racing_number, race_event.overall_rank, race_event.round, standings.total_points FROM series INNER JOIN cycle ON cycle.cycle_id = race_event.racing_cycle INNER JOIN class ON class.class_id = race_event.class_id INNER JOIN race ON race.round = race_event.round AND race.series_id = race_event.series_id AND race.class_id = race_event.class_id INNER JOIN racer ON racer.racer_id = race_event.racer_id INNER JOIN standings ON standings.racer_id = racer.racer_id AND standings.class_id = race_event.class_id AND standings.series_id = race_event.series_id INNER JOIN race_event ON series.series_id = race_event.series_id WHERE race_event.class_id = '$class_search' ORDER BY rank, race_date The first query averages about 0.085 seconds from the mysql prompt, the second about 0.075 seconds and the 3rd 0.065 seconds.

Re: Is there Examples and Documents on joining tables?
Send me create-table scripts and population scripts and I'll do this for you. But on rereading your message I'm guessing that your normalization is wrong. You have more than one multi-valued dependency. Your example description is either wrong or insufficient. T1 (presumably the parent of all parents) has a PK of let's say A. T2 has an FK into T1 := A. T3 should not have any trace of A or B or C, all of which are derivable. I hope this won't strike you as pedantic, but you get into severe problems when you store multiple multi-valued keys in any given table. This is the difference between 3NF and 4NF+BCNF. Jargon aside, suppose the following: T1 = Customers, with columns CityID, RegionID and CountryID Should you choose this model, you either: a) force the front end to intelligently preclude absurd options; or b) face the prospect of such entries as Toronto, New York, Japan. IMO this is obviously incorrect. The most you need to store is the least you need to store. Instead of this method, consider a cascading alternative: Cities -= Regions -= Counties All you need to store in this model is the CityID, since this is enough to distinguish Springfield, Ohio from Springield, Nebraska. a) you don't need to carry the cascading FKs and b) they are counterproductive even should you choose to carry them, for they either permit nonsense or you force the front end to carry mucho additional logic that is not properly part of the front end. Instead consider intelligent multi-table queries that retrieve for example Vancouver, BC, Canada and Vancouver, WA, USA. This makes your front end smarter and your back end more resilient. Examples of this are abundant. A front end that permits you to transfer employee 123 from department 234 to department 234 are IMO bad, beneath consideration of serious programming. We have to be a lot smarter than that. Given a screen that allows employee-transfer, the least it could do is preclude transfer to the same department! Lest I sound like some proselitizer, I only do so because I have made this mistake a dozen times and paid the price. At this late stage in the game, I now fully appreciate the virtues of BCNF+4NF and hope never to make this mistakes again. Normalize to the max and you're guaranteed to be correct. Codd is no fool. He is a genious and the more you read him the more sense he makes. I wish I were an order of magnitude close to his perceptions. I look back on my errors and realize I should have read him more closely, and obeyed his edicts even if I couldn't comprehend them at the time! - Original Message - From: damovand [EMAIL PROTECTED] To: [EMAIL PROTECTED] Cc: mysql [EMAIL PROTECTED] Sent: Thursday, October 03, 2002 8:08 PM Subject: Re: Is there Examples and Documents on joining tables?

Supposing that you have tables Products, Suppliers and Categories, which Products having foreign keys referencing Suppliers and Categories...

RE: raid vs splitting the database
Hi, In my experience (assuming that you are using mysql for all of these operations) the best way is to separate your tables into read-heavy and write heavy and put each into separate databases. Put the write-heavy logs database onto a separate disk/spindle and use delayed inserts (so that the apps can carry on regardless). With the read-heavy tables, use raid and/or use heap tables and serve as much from memory as possible to get max performance. Hardcore Option: If you have heavy logging to a few tables lots of reads (but not many updates to those tables you're reading from) from lots of other tables (as I do..) use replication over a few machines for the read-heavy tables, do the all selects from there and also write the logs to those machines (but don't replicate the logs) then each day/month (do this at a quiet time...whenever/whatever suits you) dump all the logs to another machine for analysing purposes. This effects a rollover of logs and can be quite useful if you're writing lot's of logtables each day.

I'm wanting to improve my disk performance and I'm wondering if I should go with Raid 10 or if I should simply mirror the drives so that I have redundancy and then put some of my tables on one drive and some on the other. Or the third option is to put the tables on one drive and the logs on another drive. Ultimately, what is going to give me the best performance?

Replication issue in 4.0.4
We have a 4.0.4-beta master and slave. The slaving process starts correctly, but randomly (and frequently) has issues. When the server starts, it will slave, but eventually will hit one of two conditions: - Duplicate key insert error (we re-sync'd the slave by hand during the install, copying databases by hand, etc, so they're known good) - Signal 8. The database will hit Signal 8, die, and be restarted. Immediately upon restarting, it dies, and restarts, ad naseum. The Dupkicate Key insert doesn't have any decent or recognizable accompanying errors, however the signal 8 leaves the following in the logs: 021003 18:04:03 mysqld restarted /usr/local/libexec/mysqld: ready for connections 021003 18:04:03 Slave I/O thread: connected to master '[EMAIL PROTECTED]:3306', replication started in log 'dbmaster1-bin.002' at position 110748 mysqld got signal 8; This could be because you hit a bug. It is also possible that this binary or one of the libraries it was linked against is corrupt, improperly built, or misconfigured. This error can also be caused by malfunctioning hardware.

MySQL Index Efficiency
I have a table with millions of records, lots of fields, and lots of indexes. It appears I break every rule for table efficiency...but there is a reason! I needed to do summarized data on *lots* of the fields at once, and the savings in time simplicity far outweigh any performance hits I may have come up against (which are few). However, I have a question on the best design for an index. Let's say I have three fields in particular I usually summarize the dataset with: Date, Country and CustomerType. Typically I would always query the table with a specific Date in mind (in -MM-DD format), but often I would also supply Country and/or CustomerType. Within a specific date range, Country would have less than a dozen variants, while CustomerType may have less. So a couple sample queries would be: Select Country,Sum(sales) From MyTable Where (Date'2002-01-01' and Date'2002-09-01') Group By Country Select CustomerType,Sum(sales) From MyTable Where (Date'2002-01-01' and Date'2002-09-01') Group By CustomerType Select CustomerType,Sum(sales) From MyTable Where (Date'2002-01-01' and Date'2002-09-01') And Country='Canada' Group By CustomerType If I understand the MySQL documentation correctly (and I probably don't!), the most efficient index would be to have indexes with Country and CustomerType listed first, since their values number far less than Date. This would mean indexes of: Date,Country Date,CustomerType Country,Date CustomerType,Date Country,CustomerType,Date CustomerType,Country,Date That seems like a lot to me. If I simply made Date the first entry on all it would be: Date,Country,CustomerType Date,CustomerType,Country But, as I said, would having the date first be efficient? Any thoughts would be appreciated!

Re: RPM Install appears to have failed

Create table if not exists from mysqldump?
Hi, I am trying to use mysqldump to dump the structure of a single database and want the output to make create table commands that include the IF NOT EXISTS switch so that when the file is imported into an existing database it does not write over tables with the same name. Does anyone know if this is possible with mysqldump and if so what option achieves this?

key blocks
How would one go about changing the key block size for a table/database/server? As I understand it, key blocks are 1024 bytes (1k) by default. I am creating an ext2 partition with 16k blocks for a database with tens of millions of records and would like to optimize the key block size to the fs block size for optimal index usage. I can't seem to find any information about changing this value. D.

Help tunning a FreeBSD machine for postfix+mysql PLEASE!!
People, I'm running a postfix server with mysql on a FreeBSD machine. This mail server holds about 500 virtual domains and 6000 virtual accounts. Using the command mysql -e show processlist;|wc -l I get the current amount of mysql conns. It floats at about 150-200 simultaneous connections on mysql. When it hits 240 connections I get the error: ERROR 1135: Can't create a new thread (errno 35). If you are not out of available memory, you can consult the manual for a possible OS-dependent bug This happens too often for a production machine. There are 2GB RAM, double-Xeon, 150GB RAID5, etc. For instance, we replicated mysql on another 2 machines, so we keep balancing the load by hand on those 3 machines. Each supports 240 mysql connections. I already have tweaked a little FreeBSD's kernel with the following: kern.osrelease: 4.6.2-RELEASE kern.maxusers: 512 kern.maxproc: 8212 kern.maxfiles: 131072 kern.maxfilesperproc: 65536 kern.maxprocperuid: 7390 kern.ipc.nmbclusters: 65536 kern.ipc.maxsockets: 65536 Also, I'm using softupdates and async on disks (SCSI Ultra-3 w/ hardware raid5). I have pulled kern.maxusers to 2048 but machine begun to crash, so I kept on 512. Any idea why? If anybody has any idea about how to increase the number of concurrent conns of mysql, please help me. I've searched mysql, freebsd and postfix sites, forums archives and could not find howto solve this. Please, this machine is in production and I must solve this to pull more 15.000 accounts into this machine! Any idea, help or anything will be appreciated. If you need more info, pelase ask.
