Converting Column to SET
I'm converting a database where multiple selections from a valuelist were stored delimited within a single field with a \r. I imported this data into MySQL 3.23.46 and imported the valuelist selections as is into a VARCHAR field large enough to hold all selections. I'm fine storing selection values to the MySQL field using the existing middleware valuelist routines. However, I now find myself in a pickle when it comes to searching that field for combinations of values. The previous database compared each value in my search string with each value as an independent contains. So, if I had red, blue, green, black as selection choices, and a field had red \r green \r black, (spaces are for readability only) I could search for red \r black and get a list of found records. In MySQL I can search with a single selection red and specify a 'contains' operator with my middleware (Lasso Pro 5) and get a list of records. However, I cannot include more than one option in my search string. It's obvious (and understandable) that MySQL is searching with a literal red \r black string, and finds no matches. Questions: 1 - is there a way with some SQL expression to search the existing field and \r delimited data with a string such as red \r black to reproduce the same search I had before? (I know this will not be as fast as SET). 2 - if I convert this column to a SET and define my choices, will MySQL automatically recognize the existing \r delimited values in the fields and properly convert the field data to its own preferred format for SET fields? 2a - do I first have to manually convert all \r instances to commas or something else? 2b - do I have to export the data, redefine the column as SET, then reimport it into this column? 3 - what happens to field data when the SET selections are redefined? The reason behind the previous setup was to allow easy changes to the selection list and isolate the definition of the list from the database. I know SET is faster, but these are really small databases.

Question about displaying of 'timestamp' field

His interest lies not so much in using for database table modeling, but for PHP and Perl development. How does PHPEd stack up compared to other PHP IDE's? What experience (good or bad) has anyone had with it? Is there another product that is better? I've just finished using Quanta+ for doing a fairly small PHP frontend to a MySQL database. I didn't choose this for any reason other than it got installed on the Suse-based laptop I was using. Got to say though, it's pretty slick (syntax highlighting, inbuilt docs, inbuilt preview, etc) - and best of all free from Sourceforge. However, since I'm now getting more into the web development, (heck I quite like PHP!), side of things I'm now thinking of spending the USD49.99 (CD version, download-only is USD10 cheaper) and getting the uprated version - Quanta Gold - from TheKompany. Certainly the feature list and screenshots look good. To me, USD500 sounds an awful lot of money for a 'mere' PHP/Perl editor. The cynic in me would wonder if it's not overkill. I used to do all my PHP and Perl stuff just using the appropriate modes in Xemacs which is free. Xemacs doesn't have the nice inbuilt docs and project handling that Quanta does though.

This off topic, but one of our programmers is interested in NuSphere's PHPEd development interface and I would liek some feed back from other users. His interest lies not so much in using for database table modeling, but for PHP and Perl development. If he's not really that interested in the mysql integration than I would say that you could probably go with a different IDE. PHPed's db integration and built-in php debugger are about the only two things that set it apart from other IDE's. I am well aware of the conflict a few months ago between MySQL and NuSphere, but I have never heard anything one way or the other about PHPEd. At nearly $500 per package, it is not a decision I wish to make without some feedback from the community. How does PHPEd stack up compared to other PHP IDE's? What experience (good or bad) has anyone had with it? Is there another product that is better? Any feed back (either to the list or me me privately) will be appreciated. Before you make a commitment, you can apply for a trial version of PHPed. You have to give them real contact information, (I think I've gotten like 5 sales-pitch emails since I downloaded my free trial 3 months ago.) So you can give it a shot before you buy... and at $500 you should probably try it first. As for feedback on experience with the editor: When you try to install the editor (at least this was what it did three months ago) It wants to install it's own copies of Apache and MySQL. kind of un-handy if you've got current installs you want to use. I think it gave you the option to keep your own, but after I got everything installed, the database integration wouldn't work. So I decided that I had free time on my hands, I hosed my installs of apache and mysql and let it install it's own stuff. after that I still couldn't get it to work properly. I probably could have tweeked something here or there and gotten everything to go, but my reaction was kind of like.. I'm going to pay $300 to have to play with it this much to get it to work? It just didn't seem worth it Given that I currently used allaire's homesite and the only things that PHPed had over that in features was the db integration and php debugger, and I had already worked out my own solutions to those problems. I recommend downloading the trial version before you buy. I also recommend downloading the trial version of homesite as well. Homesite gives you syntax highlighting, project management, web deployment. scriptable deployment wich lets you decide what gets sent, where it gets put etc... all in a script that you can re-run. Plus homesite let's you edit the ide to add in features that you may need (http://www.macromedia.com/software/homesite/) Or look into Quanta depending on what platform you plan on developing on. I found it ironic that if you buy PHPed standard, it only runs on windows platforms, and that if you decided to buy PHP advantage, then you get linux support. seems like it should be the other way around given that the product they are trying to sell was built on the back of Open Source technologies.

Innodb Tables in MySql 4.0 ?
Ive just downloaded Mysql Max 4.0 binary distribution for Windows ... Does this distribution supports Innodb tables ? How do I turn on this feature ? I follow the instruction (modifying my.ini to include support for innodb ) buy Mysql does not start ( I am using Winmysqladmin ) and I am using mysqld-max-nt.exe And starts well if I comment all INNODB features ... I don't want to go on trying, if this Binary Dist. have not been compiled with this feature .. Is there anyway to see if the binary Dist, was compiled with Innodb support ?

If he's not really that interested in the mysql integration than I would say that you could probably go with a different IDE.

I am well aware of the conflict a few months ago between MySQL and NuSphere, but I have never heard anything one way or the other about PHPEd. At nearly $500 per package, it is not a decision I wish to make without some feedback from the community. How does PHPEd stack up compared to other PHP IDE's? What experience (good or bad) has anyone had with it? Is there another product that is better? Any feed back (either to the list or me me privately) will be appreciated. Before you make a commitment, you can apply for a trial version of PHPed. You have to give them real contact information, (I think I've gotten like 5 sales-pitch emails since I downloaded my free trial 3 months ago.) So you can give it a shot before you buy... and at $500 you should probably try it first. As for feedback on experience with the editor: When you try to install the editor (at least this was what it did three months ago) It wants to install it's own copies of Apache and MySQL. kind of un-handy if you've got current installs you want to use. I think it gave you the option to keep your own, but after I got everything installed, the database integration wouldn't work. So I decided that I had free time on my hands, I hosed my installs of apache and mysql and let it install it's own stuff. after that I still couldn't get it to work properly. I probably could have tweeked something here or there and gotten everything to go, but my reaction was kind of like.. I'm going to pay $300 to have to play with it this much to get it to work? It just didn't seem worth it Given that I currently used allaire's homesite and the only things that PHPed had over that in features was the db integration and php debugger, and I had already worked out my own solutions to those problems. I recommend downloading the trial version before you buy. I also recommend downloading the trial version of homesite as well. Homesite gives you syntax highlighting, project management, web deployment. scriptable deployment wich lets you decide what gets sent, where it gets put etc... all in a script that you can re-run. Plus homesite let's you edit the ide to add in features that you may need (http://www.macromedia.com/software/homesite/) Or look into Quanta depending on what platform you plan on developing on. I found it ironic that if you buy PHPed standard, it only runs on windows platforms, and that if you decided to buy PHP advantage, then you get linux support. seems like it should be the other way around given that the product they are trying to sell was built on the back of Open Source technologies.

Logging problem with --log, my.cnf etc.
Hello, I am using MySQL 3.23.36 on Linux. This is a small gripe about a product I am otherwise very happy with. I hope I have not missed the obvious or been stupid some other way. The problem - I want to log somewhere other than $DATADIR. Things are set up like ; | log | ON | log_update | OFF | log_bin | OFF | log_slave_updates | OFF | I would have liked to use the my.cnf file to achieve this but it doesn't appear to work i.e. a line like (in the [mysqld] section) ; log=/var/log/mysql.log has no effect. Looking at 'mysqld --help' output would show this is set i.e. logfile: /var/log/mysql.log but this file is not created. In fact, logging appears to stop. So, I thought I would try adding the argument to my mysql init script - args that are passed to 'safe_mysqld' i.e. In /etc/init.d/mysql I added ; --log=/var/log/mysql.log to the command line for 'safe_mysqld'. But this too had no effect - no log file created, no logging. So ... I decided to look at 'safe_mysqld'. This is a much more complex program but, seemed to me, to be potentially ignoring a '--log' line i.e. In the 'case' statement near the top ; for arg do case $arg in # these get passed explicitly to mysqld --basedir=*) MY_BASEDIR_VERSION=`echo $arg | sed -e s;--basedir=;;` ;; --datadir=*) DATADIR=`echo $arg | sed -e s;--datadir=;;` ;; --pid-file=*) pid_file=`echo $arg | sed -e s;--pid-file=;;` ;; ... There is no catch for '--log', and I assume the catchall default ; *) if test -n $pick_args ... misses it as well (or it's ignored later ...). So ... I (probably badly) hacked this script a bit and now I have logging to /var/log/mysql.log. I was looking in some 'changelogs' and found no mention of problems. I also searched the list archives and found one other person with a similar problem which was never resolved ; http://lists.mysql.com/cgi-ez/ezmlm-cgi?1:msp:24135:lkonncgmkabnpiggbdio So, would someone take a look at this and see if they can figure out where the problem lies? I admit it might be me.

Gemini Tables and NuSphere Update
I am a new MySQL user, so forgive my stupidity for asking the following question (perhaps taboo). What is the latest on NuSphere vs MySQL AB? What about Gemini. I have searched everywhere for info, but can't seem to find anything after November of last year. I have serious needs for transaction processing, but don't know which way to turn. Should I undertake using NuSphere's (supposedly stable) Gemini tables. There seems to be a lack of info on these tables now. I am trying to get a grasp on what happened to this MYSQL AB vs NuSphere deal, but all of the posts about it seem to have vanished. In addition, my first impression of Gemini was not good as I did some simulated crash test and corrupted the tables without much trouble. Perhaps it was unrelated. But it is worth further investigation. Or should I look at the InnoDB tables (which are still considered beta). Any opinions?

foreign keys to what end?
I have a MySQL InnoDB table for ACH (checking account) transactions that includes, among other fields, the below: trans_id (PRIMARY KEY) cust_type routing_num status site_id payment_type auth_type trans_type trace_num All of the above fields (except the primary key) are related to other tables that describe the customer type, transaction type, etc. or have valid values for routing number, status, etc. Should all of these be set up as foreign keys, or should some of referential integrity be done programmatically? How do you draw the line between how many foreign keys are too many, or is there no such thing? Should things like this always be handled by foreign keys instead of error checking in the program? The indexing along would seem to get fairly large in the transactions table if I set them all up as foreign keys.

Upgrade problem from 3.22.27-2 - 3.23.37-8
Hi, I have the following problem: I had to install a complete new server with Suse 7.2 (MySql: 3.23.37-8). From the the old installation I only got the backup files (created with 'mysqldump database my_databases.sql') and the the database file (ISD, ISM, frm). My problem is: I can't read the backup file (mysql database backup-file.sql). Executing the command nothing happens. Using the restore table syntax only empty tables are created. Does anybody has an idea who to get the data from the old files in the database version.

mySQl JDBC connectivity in Windows.

Windows 2K, I am using JDBC and have the mySQL odbc software installed. I am running
mysql from the command line prompt in Windows 2k. I fear I may be doing something
wrong, if anyone has a step by step solution, i would be so grateful. This is the code
in my Java application that i am having problems with. Becuase of this problem I am
having to use Microsoft access, and can connect to that no problem. What do i need to
change to make it compatable with myswl, i have been trying fro ages but had no
luck.Any help with this would be more than helpful and appreciated.

Non-Sequential Primary Key Index
I have the following table: CREATE TABLE phpSP_users ( primary_key mediumint(8) unsigned DEFAULT '0' NOT NULL auto_increment, user varchar(50) NOT NULL, password varchar(30) NOT NULL, userlevel smallint(3) DEFAULT '0' NOT NULL, service_name varchar(50) DEFAULT 'A Childs Place', full_name varchar(50), visit_count smallint(5) unsigned DEFAULT '0', last_visit date DEFAULT '-00-00', active_user varchar(5) DEFAULT 'TRUE', teachers_child varchar(5) DEFAULT 'FALSE', email varchar(50), childs_name_1 varchar(50), childs_name_2 varchar(50), phone_number varchar(30), PRIMARY KEY (primary_key), KEY user (user), KEY primary_key (primary_key) ); My host has phpMyAdmin 2.0.1 and MySQL 3.22.21. When I delete rows from the database in phpMyAdmin, it does not update the Primary_Key field, so the numbers are NOT sequential. Would this pose a problem? I've tried to run myisamchk, CHECK TABLE through phpMyAdmin but it doesn't work. It gives me a syntax error all the time. Check this out: http://www.phpwizard.net/phorum/read.php?f=1i=3136t=3103 I was thinking perhaps that I might have another type of table becasue of my MySQl version, I ran ALTER TABLE to change it to a MYISAM table. That didn't give me any errors but I still could not run CHECK TABLE. I tried running the isamchk (old command) no luck. I do not have remote access to the database. Need some help here Thanks a big bunch Also--- I am looking for a good way to edit the database offline, but I havn't seen anything really streamlined. I want to take the SQL files generated, edit the database and upload the changes. What program is good for this?

mysqlbug: SIGALRM hangs read() on socket racecondition
Description:
I'm seeing random hung reads() after a mysql insert that appears to be
related to a sig alarm race condition. The basic workflow of this program
is
while (1)
recvfrom() /* few hundred packets a sec */
parse packet
insert into sql
However, once per second a sig alarm is generated which does house keeping
and what-not. This will work for minutes or hours, but eventually the
read(3, ...) blocks , which is the mysql socket. When this occurs you just
see the repeated sig alarms being catch, but immediately returning to that
read() which never returns. Note there is still hundreds of udp packets
coming in but never able to be read because the never-returing read(3,) on
the mysql sock.
Normal syscalls resemble:
write(3, \1\1\0\0\3INSERT INTO call_logging.de..., 261) = 261
read(3, \3\0\0\1, 4) = 4
read(3, \0\1\0, 3)= 3
recvfrom(5, ...) = 398
When the condition occurs:
read(3, 0x814a6b0, 4) = ? ERESTARTSYS (To be restarted)
--- SIGALRM (Alarm clock) ---
time(NULL) = 1014267832
rt_sigaction(SIGALRM, {SIG_IGN}, {0x4002fa10, [ALRM], SA_RESTART|0x400}, 8)
= 0
alarm(1)= 0
rt_sigaction(SIGALRM, {0x4002fa10, [ALRM], SA_RESTART|0x400}, {SIG_IGN}, 8)
= 0
sigreturn() = ? (mask now [])
read(3, 0x814a6b0, 4) = ? ERESTARTSYS (To be restarted)
--- SIGALRM (Alarm clock) ---
time(NULL) = 1014267833
rt_sigaction(SIGALRM, {SIG_IGN}, {0x4002fa10, [ALRM], SA_RESTART|0x400}, 8)
= 0
alarm(1)= 0
rt_sigaction(SIGALRM, {0x4002fa10, [ALRM], SA_RESTART|0x400}, {SIG_IGN}, 8)
= 0
sigreturn() = ? (mask now [])
read(3, 0x814a6b0, 4) = ? ERESTARTSYS (To be restarted)
--- SIGALRM (Alarm clock) ---
Fix:
Have to restart entire program to get it working again.

Problems finding parts of mysql on FreeBSD
I didn't pick the operating system( I don't know it well at all ), and didn't do the install of mysql on this system, but now I have to figure out where things are and how to fix it. What I am use to, is installing on Red Hat with the rpm. ( if someone knows the differences in the operating systems and the setup of mysql, you can see why I am confused) The rpm is nice enough to put mysqld in the /etc/init.d and respective places on Red Hat The FreeBSD doesn't even have these locations, nor does it have a mysqld anywhere We have the server rebooting every Monday morning ( why are we rebooting the server? don't know, its the specifications set from above ) from a cron job So, the mysql server is not starting up. Is there supposed to be some version of the mysqld somewhere? Or am I expected just to call safe_mysqld myself from cron? Can someone please point me in the right direction? (unfortunately I don't have time to learn the nature of FreeBSD at the moment) Luc Foisy - 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: Logging problem with --log, my.cnf etc.
Does mysql have permission to write to that location? -Original Message- From: alastair [mailto:[EMAIL PROTECTED]] Sent: Thursday, February 21, 2002 10:33 AM To: [EMAIL PROTECTED] Subject: Logging problem with --log, my.cnf etc. Hello, I am using MySQL 3.23.36 on Linux. This is a small gripe about a product I am otherwise very happy with. I hope I have not missed the obvious or been stupid some other way. The problem - I want to log somewhere other than $DATADIR. Things are set up like ; | log | ON | log_update | OFF | log_bin | OFF | log_slave_updates | OFF I would have liked to use the my.cnf file to achieve this but it doesn't appear to work i.e. a line like (in the [mysqld] section) ; log=/var/log/mysql.log has no effect. Looking at 'mysqld --help' output would show this is set i.e. logfile: /var/log/mysql.log but this file is not created. In fact, logging appears to stop. So, I thought I would try adding the argument to my mysql init script - args that are passed to 'safe_mysqld' i.e. In /etc/init.d/mysql I added ; --log=/var/log/mysql.log to the command line for 'safe_mysqld'. But this too had no effect - no log file created, no logging. So ... I decided to look at 'safe_mysqld'. This is a much more complex program but, seemed to me, to be potentially ignoring a '--log' line i.e. In the 'case' statement near the top ; for arg do case $arg in # these get passed explicitly to mysqld --basedir=*) MY_BASEDIR_VERSION=`echo $arg | sed -e s;--basedir=;;` ;; --datadir=*) DATADIR=`echo $arg | sed -e s;--datadir=;;` ;; --pid-file=*) pid_file=`echo $arg | sed -e s;--pid-file=;;` ;; ... There is no catch for '--log', and I assume the catchall default ; *) if test -n $pick_args ... misses it as well (or it's ignored later ...). So ... I (probably badly) hacked this script a bit and now I have logging to /var/log/mysql.log. I was looking in some 'changelogs' and found no mention of problems. I also searched the list archives and found one other person with a similar problem which was never resolved ; http://lists.mysql.com/cgi-ez/ezmlm-cgi?1:msp:24135:lkonncgmkabnpiggbdio So, would someone take a look at this and see if they can figure out where the problem lies? I admit it might be me.

( if someone knows the differences in the operating systems and the setup of mysql, you can see why I am confused) The rpm is nice enough to put mysqld in the /etc/init.d and respective places on Red Hat The FreeBSD doesn't even have these locations, nor does it have a mysqld anywhere Assuming you are using the mysql port (ports/packages are FreeBSD's equivalent to RPMs. See http://www.freebsd.org/ports ), the startup scripts are in /usr/local/etc/rc.d, and mysqld lives in /usr/local/libexec. If you did not build using the port, then no startup scripts were installed and you'll probably have to run mysqld_safe yourself from /etc/rc.local. -- Dan Nelson [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: Logging problem with --log, my.cnf etc.
On Thu, Feb 21, 2002 at 01:02:02PM -0500, Luc Foisy wrote: Does mysql have permission to write to that location? Yes. I'm starting and stopping MySQL using an init script a la Redhat. This calls 'safe_mysqld' with some args (e.g. --user,--pid-file etc.) - all started as user root as usual. The problem is that I could not see the '--log' file getting recognised or used in safe_mysqld. As I said, I would much rather be using /etc/my.cnf with the log= syntax. What I did in 'safe_mysqld' was ; 1) Add --log=/var/log/mysql.log to the call to safe_mysqld in my mysql init script 2) Add --log=*)log=`echo $arg | sed -e s;--log=;;` ;; to the 'case' statement at the top. 3) After the USER_OPTION= block further down I added ; LOG_OPTION=--log=$log touch $log; chown $user $log 4) Added $LOG_OPTION to the actual call to $MYSQLD (x2) near the bottom. This is a production machine I am playing with here at work so I am limited in what I can screw around with. I need to re-test this stuff at home again. But - has anyone managed to change MySQL's log file using my.cnf and the log= syntax?

RE: foreign keys to what end?
Using foreign keys is a really, really good idea. Programs can't be trusted (and what about running sql queries ad hoc). Even with a really big database I wouldn't get rid of the keys, just time to move to a bigger better machine/configuration. -Original Message- From: David Felio [mailto:[EMAIL PROTECTED]] Sent: Thursday, February 21, 2002 11:19 AM To: [EMAIL PROTECTED] Subject: foreign keys to what end? I have a MySQL InnoDB table for ACH (checking account) transactions that includes, among other fields, the below: trans_id (PRIMARY KEY) cust_type routing_num status site_id payment_type auth_type trans_type trace_num All of the above fields (except the primary key) are related to other tables that describe the customer type, transaction type, etc. or have valid values for routing number, status, etc. Should all of these be set up as foreign keys, or should some of referential integrity be done programmatically? How do you draw the line between how many foreign keys are too many, or is there no such thing? Should things like this always be handled by foreign keys instead of error checking in the program? The indexing along would seem to get fairly large in the transactions table if I set them all up as foreign keys.

Best solution for a very busy MySQL server
Hello, Have a look at : http://www.compagnie.com/stef/solution1.jpg http://www.compagnie.com/stef/solution2.jpg I'm searching for a solution to change a high traffic mysql server with a distributed system. 1)Is the solution 1 is good for a writing + reading access ? Are there problems with locking processus ? 2)Is the solution 2 is good for : -direct writing to mysql server (insert, update, replace ...) -using MyODBC to read tables (select) 3) I found another MySQL cluster solution http://prometheus.zerodivide.net/mysql_cluster/about/ This system uses MySQL replication.

Hello !
Here's what I did :
rpm -i MySQL-3.23.49-1.i386.rpm MySQL-client-3.23.49-1.i386.rpm
Here's what I got : A mess.
Any attempt to start any part of mysql( mysqladmin, etc) blows up in a
very similar fashion.
I have repeated this, from download of the rpms on down.
Kernel = 2.2.16-22, which could be a problem. Before having
to do such major surgery, including at least another 8 patches,
I'd like to know that it's worth it !
glibc2 = 1.92-14
I'm hoping I've done something obviously stupid.
Any suggestions welcomed !
Here's the log :
Preparing db table
Preparing host table
Preparing user table
Preparing func table
Preparing tables_priv table
Preparing columns_priv table
Installing all prepared tables
mysqld got signal 4;
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=16773120
record_buffer=131072
sort_buffer=2097144
max_used_connections=0
max_connections=100
threads_connected=1
It is possible that mysqld could use up to
key_buffer_size + (record_buffer + sort_buffer)*max_connections = 233979 K
bytes of memory
Hope that's ok, if not, decrease some variables in the equation
Attempting backtrace. You can use the following information to find out
where mysqld died. If you see no messages after this, something went
terribly wrong...
Stack range sanity check OK, backtrace follows:
0x806e214
0x811d258

0x807373d
Stack trace seems successful - bottom reached
Please read http://www.mysql.com/doc/U/s/Using_stack_trace.html and follow
instructions on how to resolve the stack trace. Resolved
stack trace is much more helpful in diagnosing the problem, so please do
resolve it
Trying to get some variables.
Some pointers may be invalid and cause the dump to abort...

('localhost','root','','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y')
thd-thread_id=1
Successfully dumped variables, if you ran with --log, take a look at the
details of what thread 1 did to cause the crash. In some cases of really
bad corruption, the values shown above may be invalid
The manual page at http://www.mysql.com/doc/C/r/Crashing.html contains
information that should help you find out what is causing the crash
Installation of grant tables failed!
Examine the logs in /var/lib/mysql for more information.
You can also try to start the mysqld daemon with:
/usr/sbin/mysqld --skip-grant
You can use the command line tool
/usr/bin/mysql to connect to the mysql
database and look at the grant tables:
shell /usr/bin/mysql -u root mysql

Re: Gemini Tables and NuSphere Update
Hi! Or should I look at the InnoDB tables (which are still considered beta). InnoDB tables are classified as gamma by Innobase Oy and MySQL AB. The text on the MySQL-Max download page is lagging behind (says beta), but to balance it, on the front page MySQL AB classifies MySQL-Max as stable :). A December quickpoll at the MySQL website showed InnoDB market share at 10 %, BDB 3 %, MyISAM 80 %, ISAM 5 %, of 3000 people who responded. Mytrix, Inc. is maybe the largest MySQL database site in the world (if someone has more than 1 TB data, please step forward), and they use InnoDB tables. See http://www.innodb.com/userstories.html.

Hi, I am running SuSE 7.3 Professional and i downloaded the binary files for Max 4.0 version from here: http://www.mysql.com/downloads/mysql-max-4.0.html I followed the installation procudure to the letter from this file: /mysql-max-4.0.1-alpha-pc-linux-gnu-i686/INSTALL-BINARY in the archive. I ran: mysql_install_db without any problems. All the setting were kept exactly as stated in the INSTALL-BINARY file. However I can not run: bin/safe_mysqld --user=mysql as linux root or as any other user on the local host. As a matter of fact the file does not even exist... The closest I have to the above file is: :/usr/local/mysql/bin/mysqld_safe Now I also tried to run this scripts with all user linux accounts and by using the -u root option as oposed to --user=mysql (I also tried --user=root from within all linux accounts.

Selecting set members
If I have a table with a set such as this:
CREATE TABLE application (
application_num int(6) NOT NULL auto_increment,
availability set('weekdays','weekends','mornings','afternoons')
default NULL, PRIMARY KEY (application_num)
) TYPE=MyISAM;
is it possible to search based on members of the set?
For example, someone might have selected ('weekends,mornings')
for their entry in this set, and I am interested in searching
for people who are available in the morning. However running a
query such as:
mysql select * from application where availability = 'mornings';
would not return a person who is available for both weekends and
mornings, since there set entry would be 'weekends,mornings'.
Writing querys to try to cover all the posibilities such as:
mysql select * from application where availability = 'mornings' or
availability = 'weekends,mornings' or ... ;
Seems like the wrong thing to do. Anyone have any ideas? I wouldn't
be using sets if I could, but I am stuck with them for this prjoect.
Thanks a lot,
John

Its kind of a subtle point, but innodb's locking not only locks rows, it locks the ABSENCE of rows. If I understand correctly this means that something like: BEGIN WORK SELECT COUNT(*) FROM table WHERE starttime? AND endtime? (check the count) INSERT INTO table (if count is zero) COMMIT SHOULD do the trick. The transaction should block anything else that tries to do an insert into the same range before you do your commit. I must add you have to use a LOCKING read in the SELECT. Either SELECT ... FROM ... WHERE .. FOR UPDATE; which sets exclusive locks, or SELECT ... FROM ... WHERE .. FOR LOCK IN SHARE MODE; which sets shared locks on the rows (to be precise, index records) it encounters. Without these additional clauses the default SELECT mode of InnoDB is the consistent non-locking read of Oracle. Locking reads in InnoDB also lock the absence of rows, as Tod states.

Subject: Selecting set members
If I have a table with a set such as this:
CREATE TABLE application (
application_num int(6) NOT NULL auto_increment,
availability set('weekdays','weekends','mornings','afternoons')
default NULL, PRIMARY KEY (application_num)
) TYPE=MyISAM;
is it possible to search based on members of the set?
For example, someone might have selected ('weekends,mornings')
for their entry in this set, and I am interested in searching
for people who are available in the morning. However running a
query such as:
mysql select * from application where availability = 'mornings';
would not return a person who is available for both weekends and
mornings, since there set entry would be 'weekends,mornings'.
Writing querys to try to cover all the posibilities such as:
mysql select * from application where availability = 'mornings' or
availability = 'weekends,mornings' or ... ;
Seems like the wrong thing to do. Anyone have any ideas? I wouldn't
be using sets if I could, but I am stuck with them for this prjoect.
Thanks a lot,
John

Linking tables using INNER JOIN
I am trying to do an inner join between three tables. Here is what I have tried: select * from MapConfig LEFT JOIN ConfigString USING (id) LEFT JOIN ConfigInt USING (id) WHERE MapConfig.layername = Roads; What I am trying to do is to pull back all rows from MapConfig associated with matching rows from ConfigInt and ConfigString. What I get, though, is info from MapConfig and ConfigString ONLY, nothing from ConfigInt. If I rearrange the order that ConfigString and ConfigInt appear, I get info from MapConfig and ConfigInt ONLY, nothing from ConfigString. Is my SQL messed up or is there a limitation in MySQL on the number of INNER JOINs you can do in one statement? I suppose I could probably use a temporary table for this but I'd rather not. - 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 host has phpMyAdmin 2.0.1 and MySQL 3.22.21. Wow, your host is running quite an old version of the MySQL Server there! When I delete rows from the database in phpMyAdmin, it does not update the Primary_Key field, so the numbers are NOT sequential. Would this pose a problem? No. When you delete a row, that does not affect other rows (nor should it). I've tried to run myisamchk, CHECK TABLE through phpMyAdmin but it doesn't work. It gives me a syntax error all the time. Indeed, those internal commands were implemented somewhere in the 3.23 series. I was thinking perhaps that I might have another type of table becasue of my MySQl version, I ran ALTER TABLE to change it to a MYISAM table. That didn't give me any errors but I still could not run CHECK TABLE. MyISAM was first introduced in 3.23. The 3.22 version your host is running may just ignore the TYPE parameter in the ALTER TABLE statement, but the table type will still be old ISAM. I tried running the isamchk (old command) no luck. No luck in what way? Do you have command line access on the server, and are you allowed to stop/start the server?

RE: Can I do it with single query in mysql?
If you only interested in getting the overall sum from the child tables you could try the following: 1) Change your child create statements to: CREATE TABLE child1 ( auto_nr int(11) unsigned zerofill NOT NULL, link int(11) unsigned , value int(11), PRIMARY KEY auto_nr(auto_nr), KEY link1_key(link) ) CREATE TABLE child2 ( auto_nr int(11) unsigned zerofill NOT NULL, link int(11) unsigned , value int(11), PRIMARY KEY auto_nr(auto_nr), KEY link2_key(link) ) 2) Then create a merge table like: CREATE TABLE childMerge ( auto_nr int(11) unsigned zerofill NOT NULL, link int(11) unsigned , value int(11), KEY auto_nr(auto_nr), KEY link_key(link) ) TYPE=MERGE UNION=(child1,child2); 3) The the one statement then becomes: Select master.link, max(dat) as m_dat, sum(childMerge.value) from master left join childMerge using (link) group by master.link KEY is a synonym for INDEX Regards Dan -Original Message- From: Alvis [mailto:[EMAIL PROTECTED]] Sent: Friday, 22 February 2002 2:44 p.m. To: [EMAIL PROTECTED] Subject: Can I do it with single query in mysql?

RE: SQL query
I can't see any way of making this statement faster, however: One method to increase speed, especially since the amount of data is large is to create seperate tables into your lowest common denominator, here year (e.g. traffic_2000,traffic_2001 etc). Then create a merge table with the same name as your current one i.e. 'traffic', such that you don't break any current functionality in your application, then depending on your year value, to increase speed, consult the specific year table e.g. traffic_2001. re: http://www.mysql.com/doc/M/E/MERGE.html Regards, Daniel -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Friday, 22 February 2002 4:20 p.m. To: [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Subject: RE: SQL query My concern here is the query speed Mysql query on the statement result so slow...is there a way to improve it?

Well, you make both the WHERE as well as the GROUP statement work on the result of an expression YEAR(...) MONTH(...) rather than a constant (like a plain column). Also, since you use an expression in your WHERE, the server can't use an index on edate even if there is one. So, to process your query, the server has to do the following: - Do a full table scan, calculating the YEAR() from every edate, checking it for the right year... - Once all that is collected, it has to go through all of the result set, calculating the MONTH() from every edate, and only THEN can it start grouping and summarising. No wonder the query takes a while What type is 'edate' exactly? If it's just a DATE field, one idea could be to store the DAY/MONTH/YEAR bits as separate columns. Then, if you index the YEAR field, that index can be used to quickly find all the rows within the right year. No expression evaluation necessary. As someone else mentioned, it might also be a good idea to simply have a separate table for each year. You can always use a MERGE table if you need to do queries that span over multiple years. Anyway, with the MONTH being a separate column, the GROUP statement no longer has to evaluate an expression. So there too will it be much faster. These are just a few basic ideas... issues such as these (and much more) are covered in MySQL training courses: http://www.mysql.com/training/.

Wide Indexes
For reporting purposes, I usually use a wide index across all the fields that are relevant to creating the reports. So, for example, my sales table has this type of data: sale_id sale_date salesperson_id product_id referral_id [other sales data] sale_id is an auto_incrementing primary key. Most of the reports I run are date-based -- show me the sales for date, for salesperson, grouped by product_id and referral_id. My index for this table would be: (sale_date, salesperson_id, product_id, referral_id) My question is this: I know it's not good to index fields that have few unique values, but what about including a field like that in a wide index? If product_id only has 5 values, does it hurt to include it in this wide index? Would it be better to include it or leave it out, if I'm grouping by that field? Is there a rule of thumb for unique-ness when indexing? (i.e. a column should have X unique values before using it in an index...) Any insight is appreciated.

Finding overlapping intervals efficiently
Given two tables (t1 and t2) with fields start and end, what is the most efficient method of finding the all the intervals in the first table that overlap any interval in the second table? Right now, I use a query like: SELECT t1.name, t2.name FROM t1, t2 WHERE t1.start = t2.end AND t1.end = t2.start; I use a key (start, end) in each table. Is there anything else that I can do to optimize this type of query (i.e. add keys, change the select statement)? The tables typically have thousands of records, so optimizing this query is very important.

My problem is: I can't read the backup file (mysql database backup-file.sql). Executing the command nothing happens. Using the restore table syntax only empty tables are created.
