Waste of data while using MySQL database
Hi! I have LAN with some PC, which use MySQL database. Sometime power supplay failure occurs. I have back-UPS too, but them can't hold power for 2 or more hours and because it server loose power supplay and just stop (without correct system shut-down). I got such problem: I waste data in this situation (users waste what them did). As I understand, MySQL server don't write data on disc immediatly, but after some time. What can I do for saving data regularly (for example once at hour or something like that)? With best regards - Andis Grasis Latvia

Re: Waste of data while using MySQL database
Hi Andis. I have no experience with this, but once your UPS kicks in can you schedule a graceful shutdown after some number of minutes? On my Red Hat 7.0 machine, I see this in /etc/inittab: # When our UPS tells us power has failed, assume we have a few minutes # of power left. Schedule a shutdown for 2 minutes from now. # This does, of course, assume you have powerd installed and your # UPS connected and working correctly. pf::powerfail:/sbin/shutdown -f -h +2 Power Failure; System Shutting Down # If power was restored before the shutdown kicked in, cancel it. pr:12345:powerokwait:/sbin/shutdown -c Power Restored; Shutdown Cancelled Maurice On Wed, Jul 25, 2001 at 10:01:27AM -0700, Andis wrote: Hi!

Bad optimization on ORDER BY .. DESC.
Hello All,
When I use order by .. DESC in query, time always more then in
order by .. ASC case.
Explain say Using filesort,in DESC case query.
Why???
Why I can't use key value in select like that:
select * from TableName where KEY(KEYNAME)concat('value1','value2')
or
select * from TableName order by KEY(KEYNAME)
I think in that case query optimizing will be more simple.
example:
CREATE TABLE cSectText (
SectID int(11) NOT NULL default '0',
ID int(11) NOT NULL default '0',
Date date NOT NULL default '-00-00',
PRIMARY KEY (ID,SectID),
UNIQUE KEY SectID (SectID,Date,ID)
) TYPE=MyISAM;
mysql select * from cSectText where SectID=1 order by date desc limit 1;
++---++
| SectID | ID| Date |
++---++
| 1 | 35131 | 2001-07-16 |
++---++
1 row in set (0.15 sec)
mysql select * from cSectText where SectID=1 order by date limit 1;
++---++
| SectID | ID| Date |
++---++
| 1 | 31118 | 1993-02-15 |
++---++
1 row in set (0.00 sec)
mysql explain select * from cSectText where SectID=1 order by date desc limit 1;
+---+--+---++-+---+---+-+
| table | type | possible_keys | key| key_len | ref | rows | Extra
| |
+---+--+---++-+---+---+-+
| cSectText | ref | SectID| SectID | 4 | const | 21892 | where used;
|Using index; Using filesort |
+---+--+---++-+---+---+-+
1 row in set (0.00 sec)
mysql explain select * from cSectText where SectID=1 order by date limit 1;
+---+--+---++-+---+---+-+
| table | type | possible_keys | key| key_len | ref | rows | Extra

Upgrade/installation problem
Ok problem. Upgrade from 3.23.37 to 3.23.40 on linux readhat 7.0 - using rpm and after the uppdate I get : Cant find file ./mysql/host.frm (error: 13) so I copied the db and run mysql_install_db, still get the same msg, So I checked the error 13 = permission denined. So I doublecheck tthe permission, and even tried to give ugo=rwx on all the files, same error. So Just to se if it for some reason read from another datadit i removed the datadir, and I get Table mysql.host doesn't exists (= another error) wich tells me that it actualy is reading from the right datadir. So I tried to uninstall all the mysql rpm and installing it againg same error so what can be wrong Ran out of clues. The installation has been upgraded several times before with any problems. /roger
Re: Sorting w/ leading articles ignored
In PHP specifically, no clue.
Using Perl, something like so (and this assumes a 1:1 mapping on
titles/ids):
my $get_art_list = $sql-prepare(eosql);
SELECT title, id
FROM table
eosql
$get_art_list-execute;
my %articles;
while (my $art = $get_art_list-fetchrow_hashref) {
$articles{$art-{'title'}} = $articles-{$art-{'id'};}
my @ordered = map {$articles{$_}} sort map
{/^((a)|(an)|(the))\s+(.*)/?$3:$_} keys %articles;
# you now have @ordered, which has key ids in order the way you want them.

'SHOW DATABASES' - vi.recover
Hello, I'm having a problem with MySQL when it runs for a couple of days. At some time mysqld 'forgets' where it's databases are and searches for them in the mysql temp dir. (In my case /var/tmp). In the tmp dir there is always the recover directory for vi (vi.recover) so mysqld thinks that it's the only database. Funny enough mysql remembers what the grant rights are for all the users. I've searched the mailing lists/newsgroups for this problem. This problem was reported before by D. Jordan on 2000/10/05 and a month before that. Sadly nobody replied to it. :( Does somebody know what's going on? Specs: FreeBSD 4.3 RELEASE, Mysql 3.23.39, PHP 4.0.5, Apache 1.3.20 all built from ports.

For example, try running 'db_printlog -V', to see if it prints out its version.

By misstake i typed INSERT INTO cust VALUES(20,Maria); the id (20) then was downsized to the top limit of SMALLINT - 65535. Next time i type INSERT INTO cust VALUES(NULL,Joe); the AUTO_INCREMENT tries to increase id by 1, but it cant because AUTO_INCREMENT for id starts with 65535 and cant go any higher. Even if i delete the record where id=65535 DELETE FROM cust WHERE id=65535 AUTO_INCREMENT starts with 65535 and i cant add any more records.

hi all, I'm having a problem wrt character sets in mysql. i'm trying to add the euro symbol to a table (MyISAM), but it seems that it is being replaced with '?'. Having looked into the problem a bit, I assume it is that the table is using the default latin1 character set, which does not include the euro symbol. How have other people worked around this? I don't know how to define new character sets (technically), having looked at those defined in share/charsets/*.conf. Can somebody explain these files, or point me to somewhere I can read up on them? mysql version 3.23.37 (nt 4) rgds, Paul.

Compressed column support?
Hi, I have looked through the documentation (http://www.mysql.com/docs) and the mailing list archives (http://www.geocrawler.com/lists/3/Databases/8/0/) and find no mention of a feature that I was hoping was available: * text or varchar columns that are automatically compressed/uncompressed I have a table with highly compressible data. One of the fields is a 380-character field which represents a set of indicator flags for upcoming dates. (I am working in the travel industry.) (Please don't talk to me about third normal form... this comes from a legacy database, and it was easiest to keep their physical design.) A daily data file is 5MB compressed (300MB uncompressed). It adds roughly 300MB to the database each day! It actually is causing me to consider storing this data outside the database in compressed files. The ugliness of this is somewhat appalling however. I wish there were a feature in MySQL which would allow me to define the table to contain text or varchar columns which would be automatically compressed and decompressed dynamically (and completely transparently to the user). create table widget ( widget_id integer not null auto_increment primary key, widget_cd varchar(8) not null, indicatorstext null compressed, more_flagsvarchar(255) null compressed, unique widget_ak1 (widget_cd) ); Has there been talk of such a feature? (I am new to the list, but I didn't see it in the archives.) Would it be hard to develop? Where would one start?

Re: mysql on os x 10.0.4
At 10:44 AM -0600 7/25/01, Michael Nezi wrote: Saw your post on mysql.com and wondering if you could help me. Working with the Mac OS X Terminal Mac OS X comes with a Terminal application that can be used for issuing instructions to the OS from a command line. You will find it necessary at times to perform some tasks using the Terminal application and so should become a bit familiar with its use. When you open the terminal application it starts a shell specific for your user account. Many of the commands and utilities needed for administrative purposes however require that you open a root shell, in other words, you need to log in as the root administrator. When you install Mac OS X you set up an Administrator user name and password, this OS user account allows you to perform administrative functions but is not the root account that has complete control over all functions of the system. Apple has elected to not enable this account by default. It must be explicitly enabled for it to be available. In my opinion, when administering MySQL on the command line using the terminal program on Mac OS X you are best off not enabling the root account. The reason for this is to lessen the chance that you will create files and install programs that can only be used by root, thus not allowing the system to work for a user account with fewer privileges. It is also common practice in UNIX not to use the root account to perform general tasks and it should only be used when it is necessary. To work with just the Admin user name, prefix any command with sudo. If a password is required, you will be prompted for it. The sudo program takes as an argument a command line to be executed as root. Your user account must be included in a configuration file to be allowed to utilize this command. This file also specifies the commands you can run, in the case of Mac OS X the user that you set up when installing the OS is included on this list by default and assigned privileges that allow it to perform any task that root is able to. For example, to run the above command use: root% sudo ./mysqladmin -u root password thenewpassword Alternatively, if you will be executing a series of commands as root then start with the sudo su or sudo -s command to start a new shell as the root user. Use exit to stop issuing commands as root and exit the shell. For example: % sudo su Password: root% ./mysqladmin -u root password thenewpassword root% (another command) root% (another command) root% exit While sudo would require you to enter a password each time: % sudo ./mysqladmin -u root password thenewpassword password: % sudo (another command) password: % sudo (another command) password: % sudo etc password: If you open a root shell to accomplish a series of tasks, there will not be a need to use sudo for each command. Note that in this document, lines that begin with % indicate a UNIX command prompt, it may actually look more like: [localhost:~] mcollins% The text that follows is what would be typed into the terminal. In addition, root% at the start of the line indicates that the command needs to be issued while logged in as root or with root permissions. The Root Account If there are any other users with accounts on your server, it is essential that you protect the root account by creating a password for this account. Even if you are the only one with access to the machine, it is prudent to plug any holes that may be exploited by hackers. The key thing to keep in mind is that the OS root is not the same as the MySQL root. You don't need to have root access to the server to attempt to use the MySQL root account. There might be other user accounts to the server that may be able to navigate to the mysql utility and log in as the MySQL root with no password. This can happen even through a remote telnet session, since even though root is set to localhost only, a telnet session allows one to connect and work as a user would on the localhost. Having no root password would mean this intruder could send any SQL command to the databases, and even delete them. The root account created in MySQL uses the name root by convention, it is not required that the account use the name root, it could be changed to any name you want. Setting the MySQL root password is an example of when you will need to use the Mac OS Terminal. The task of setting the root password is accomplished using mysqladmin, one of the utility programs installed by MySQL (and MySQL). The command is as follows: root% cd /usr/local/ root% ./bin/mysqladmin --socket=/tmp/MySQL.sock -u root password thenewpassword Tip: If a password was already set for MySQL root and you want to change the password, you could add the -p option (after root in the above command), you will then be prompted for the existing MySQL root password. Starting and Stopping MySQL Mac OS X has a problem with stopping MySQL, so you need to find the process ID

Re: Please help with syntax !!!
Hi, It seems like what you are trying to do is select all messages that have child messages and display the results sorted by the parent message ID. How about... select messages.message_id, messages_1.message_id from messages, connections, messages messages_1 where connections.parent = messages.message_id and messages_1.message_id = connections.child order by messages.message_id, messages_1.message_id; Or more clearly... select parent_msg.message_id, child_msg.message_id from messages parent_msg, connections connect, messages child_msg where connect.parent = parent_msg.message_id and child_msg.message_id = connect.child order by parent_msg.message_id, child_msg.message_id; Stephen P.S. I am not an expert on MS Access and whether your original query would include parent messages which have no children (via connections) or not.

Re: installing mysql
Dear Maggie, http://mysql.com/Downloads/MySQL-3.23/mysql-3.23.39-win.zip has a SETUP.EXE which will install MySQL (database server plus client tools to work with the server) - by default it will install in C:\mysql. After setup, it's easiest to restart Windows. Now, the MySQL server should load. You will find a traffic light symbol in the system tray (lower right corner of your screen). Right click on it, and choose - Win9.x Start the server standalone (for Win 95 / 98) - or WinNT Install the service, then WinNT Start the service (for Win NT or Win 2000) If the traffic light symbol isn't there, you have to start this tool manually: - C:\mysql\bin\winmysqladmin.exe Afterwards, same procedure as above. To connect to the database server, you can use the MySQL Monitor (a command line tool, very good for learning SQL, but make sure you have a good book like Paul Dubois' MySQL, and / or the MySQL manual which is found here after setup: C:\mysql\Docs\manual.html).

Re: mysql and credit cards
So sprach »Alan Cox« am 2000-02-20 um 11:57:47 -0500 : Greetings: I was wondering if anyone has any ideas about the best way to store credit cards in a database ... and I'm not referring that much to the field type, but rather encrytption techniques. 'encryption'? Hmm, how about: none? If you don't need to reconstruct the cc#, md5 will be good. However, if you need to reconstruct it, nothing is safe. And that's quite simple: a) You need to get access to the MySQL server. Impossible to do from the outside if '--skip-networking' is used. b) So, only possible from the localhost. This means, there must have been a break in to the MySQL server. Once he's on the server, he can do anything he likes. He can also read the source code of your PHP/PERL pages. There the password will be stored, somewhere. Once the password has been found (which is nothing but a matter of time), your encryption is broken. BUT: If you're using something like C or any other compiled language and do not have the source code flying around and are sure that the password cannot be decrypted from the binary, any symetrical encryption will probably do. The last also applies, if you use a program to decrypt the cc# which is not stored on the same computer as the MySQL database. But then you need to worry about how to securly transfer the data from the MySQL database to the computer running the decryption program. So, overall, I'd say: Don't hassle with encryption: It's not worth it.

Re: AUTO_INCREMENT problem in table
Dear Peter, Even if i delete the record where id=65535 DELETE FROM cust WHERE id=65535 AUTO_INCREMENT starts with 65535 and i cant add any more records.

Urgent Help needed for installing
Hello All, I've been trying upgrade our current MySQL 3.23.39 to the 3.23.40 I have tired with both the binary distro and source distro with no luck. The install seems to go OK, but I can't start the mysql server. This is on a RH/Linux 6.2 Kernel 2.4.6 i686 system. The main problem seems to be, that our dedicated server comes with a WebHosting Mgr browser interface and Cpanel for customers to use and the MySQL installation is all tied into this. So it must be, for what I have been told, that we must use the current settings to upgrade, which I did. Datadir /var/lib/mysql I tried with Mysql-Max binary install, but couldn't get the symbolic link to work properly. I unpacked the tar in the /var/lib folder, then created the symbolic link as it specifies to the mysql folder, still no luck. I tried installing the source distro, with the ./configure --prefix=/var/lib/mysql Everything seem to install OK, but when attempting to start the mysql server, sometimes it looks for the mysql.sock in the /var/lib/mysql folder, and sometimes it looks for it in the /tmp folder. I copied the mysql.server to the /etc/rc.d/init.d folder chmoded it 500, create the various symbolic links to the /etc/rc2.d and rc3.d, rc4.d as outlined. Then if I do: /etc/rc.d/init.d/mysql stop or start it complains it can create or find the .pid file which is suppose to be in the /var/lib/mysql folder. all the chown settings are correct: chown mysql.root for the /var/lib/mysql folder I have a feeling something from the current version is causing some problems and screwing with the upgrade. If any one maybe able to shed some lite to what I maybe doing work, it would be much appreciated. Our support/tech people are very slow to responded to help and we need to have this installed in the next day and require the transaction support with BDB tables.

Re: Setting up no password users?
hello kynn,
you have to :
first you must UNDERSTAND the USER-table from mysql-DB on your box.
from that point you are able to insert directly values into USERS like
values into any other MySQL-Table:
example:
INSERT INTO USER VALUES
('localhost','Testuser','PASSWORD('little
lamer'),'Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y')
^
|
|__
no password for Testuser means:insert '' here___|
Hope it helps
Christian

MySQL vs. Oracle
I am currently trying to examine the benefits of continuing to use MySQL over Oracle. I need to know what MySQL's features are vs. those of Oracle. Also I am looking for performance data. What kind of scalability does MySQL have vs. that of Oracle. Is there (or will there be) any support in MySQL for something akin to Oracle's Parallel Server? Can I use MySQL with Veritas?

Re: error using InnoDB with LOAD DATA
George, current binary versions do not yet support rows of size 8000 bytes. The next binary version 3.23.41 will do it. If you want right now to use 8000 byte rows, you have to download the source distribution innodb-3.23.39b from www.innodb.com, replace the InnoDB files in the source distribution of MySQL-3.23.40 and compile. Regards, Heikki Copied message: ... Hello all! I'm running the current MySQL vers. with InnoDB on a Linux box.

localisation error - please, please help me
Hi, I have configured MySQL with charset latin2 on a Linux box. I made a big table with a mediumtext filed and a search engine using MySQL match-against. On the Linux box everything looked fine. Now we replaced our server to FreeBSD. I compiled the same source with the same configuration settings. Now I have several problems with special iso-latin2 characters: - For example when I search for a string which contains a character which has the code of F5 (t+F5+zsde), it selects words which is the same but contains the character with code F4 (t+F4+zsde). The difference is that the character F4 is an element of the standard character set also. They look familiar and being afraid of codepage problems some sites use F4 instead of the official F5. A nice behaviour from MySQL that it also select the words with F6 (t+F6+zsde). F5 and F6 completely different letters, although they pronounced nearly the same and the look of letter itself is similar. Again, F6 is the member of the standard codepage. - Another example if I search for a word starts with F5 (F5+rmester), I get no results from MySQL. If I use F6 (F6+rmester) which is grammaticaly completely incorrect, I get the result. This is funny because the result contains F5 (F5+rmester)! (F5 is o with two long diacritics, F4 is o with one small v turned upsidedown on the top of it, F6 is o with two dots on it. F5 F6 are the official characters, but they are different.) I would really apreciate if someone could enlighten me... Where is the problem? Is there a problem wih MySQL? Or the problem is with the localisation function of FreeBSD? Both the previous Linux server and the current BSD has setlocale installed and has the iso-8859.2 locale. I am sorry, but my English might be to week to explain the situation correctly.

Re: Join with LIMIT faster in 2 queries than 1 query, why ?

Do the names of indexes have any significance to MySQL internals or is the name merely a convenience for the DB operator ? Well, PRIMARY KEY does carry some significance... ;-) Other than that, no. But you need them if you should ever want to do an ALTER TABLE to change the index definitions. For now I try to match the index names to the column names used but I'm wondering if the name matters at all.

RE: AUTO_INCREMENT problem in table
Dear Peter, Even if i delete the record where id=65535 DELETE FROM cust WHERE id=65535 AUTO_INCREMENT starts with 65535 and i cant add any more records. Sad, but true, MySQL remembers the biggest number inserted into an auto_increment column. If you delete the row in question, the next insert will add the biggest number again. The only workaround I can see is to copy the table (without the problem id row) to another table with the same structure. Maybe someone has a better solution?! how about upgrading the smallint id column to a larger integer size? mysql ALTER TABLE cust CHANGE id INT UNSIGNED - NOT NULL AUTO_INCREMENT; / Carsten -- Carsten H.

sql/table structure question.
We have an optimization question that probably could be easily resolved with some of the additional features of some commercial database products, but, being stubborn about migrating away from MySQL (What can't it do again?) I'm looking for a solution to a particular design and optimization issue we are having. This may of course not be the most appropriate list for the question, but, it does contains perhaps the best group of individuals for which to pose it to. Here's the basic overview: We are (re)designing a manufacturing process flow (recipe) system which tracks the various processess/specficiations/parameters that a widget sees from raw material to assembly. So, essentially, we have Process Steps (generalized steps in the manufacturing process), which contain specifications (like do it for x seconds, with y tool) and parameters (do it at 80 degrees C, do it at 200T pressure). So, a flow (recipe) would contain process steps which the associated parameters/specifications in a given sequence. To accomodate this we have the following table structures: --- # The basic flow information CREATE TABLE base_flows ( flowID int(10) unsigned NOT NULL default '0', flow_title char(100) NOT NULL default '', date_added int(10) unsigned NOT NULL default '0', added_by mediumint(8) unsigned NOT NULL default '0', PRIMARY KEY (flowID) ); # Process steps CREATE TABLE process_steps ( process_stepID mediumint(8) unsigned NOT NULL default '0', process_step_name char(50) NOT NULL default '', process_step_type tinyint(3) unsigned NOT NULL default '0', process_step_location tinyint(3) unsigned NOT NULL default '0', toolID mediumint(8) unsigned NOT NULL default '0', PRIMARY KEY (process_stepID) ); # Names of step specifications/parameters (since names like Pressure) # might be reused with varying values CREATE TABLE step_specification_names ( step_spec_nameID mediumint(8) unsigned NOT NULL default '0', step_spec_name char(50) NOT NULL default '', step_spec_type tinyint(1) unsigned NOT NULL default '0', PRIMARY KEY (step_spec_nameID), KEY step_spec_type (step_spec_type) ); # Step specifications (containing the target value, a unitID referencing # measurement units (T, sec, C), max and min ranges that we want to hit, # and step_spec_nameID to reference the step_spec_name (Pressure, Temp) CREATE TABLE step_specifications ( step_specID mediumint(8) unsigned NOT NULL default '0', step_spec_nameID mediumint(8) unsigned NOT NULL default '0', target_value float NOT NULL default '0', unitID mediumint(8) unsigned NOT NULL default '0', target_max float NOT NULL default '0', target_min float NOT NULL default '0', date_added int(10) unsigned NOT NULL default '0', added_by mediumint(8) unsigned NOT NULL default '0', PRIMARY KEY (step_specID), KEY step_spec_nameID (step_spec_nameID), KEY target_value (target_value) ); # The actual recipe collections (sequences) CREATE TABLE base_flow_recipes ( flowID int(10) unsigned NOT NULL default '0', process_stepID mediumint(8) unsigned NOT NULL default '0', step_specID mediumint(8) unsigned NOT NULL default '0', seq tinyint(3) unsigned NOT NULL default '0', PRIMARY KEY (flowID,process_stepID,step_specID,seq), KEY process_stepID (process_stepID), KEY seq (seq), KEY step_specID (step_specID) ); This works reasonably well (We can fairly easily query the above data to build recipes). But, enter in some snags. 1) In order to avoid creating thousands of recipes we do things called SPLITS when we are in a development phase. Meaning, we take a few parameters and change the values / order (meaning, if we were making bread we might use 2 cups of flour as compared to 3, and do so after adding the water as opposed to before). So, we need a smart way to store changes to the above flows without recreating whole new flows. 2) It turns out not all values are clear cut floats. Ie, we might have odd ball parameters that really only have ALPHA representations. Ie, instead of it always being something like 10.2 F we might have to store LLL Oven). So, the obvious solution might be to remove the floats and use chars in the step_specifications table. Well, wait until you see 3. 3) We need a smart way to SCORE SIMILARITY between recipes (and, to make it even more complex, score similarity taking into account splits). Meaning, we want to be able to say give me the flows the closest resembly THIS flow. Or, more accurately, show me the widgets that closest resemble this widget. Meaning it should be smart enough to know that 100 C is close to 90 C then is 110 C in process step 5 of two compared flows. This is why chars become difficult to deal with. Sounds like the job of a recursive select.. but, perhaps there exists some additional table hierarchies that I'm not thinking about to easily compare multiple levels of data. Your brilliance is requested and thanked in advance,
large_files_support
Hi All:) I'm running mysql-3.23.30-gamma on FreeBSD 4.3-stable and running into a problem with max file sizes. I've got a table, names, which is taking 4294967288 bytes.

Urgent help needed, is this a version bug?
Mysql:
We have installed mysql 3.23.26 beta version to a BSD 4.2 server. It works
fine, however when we test a php file which just function to insert some
data to a table in database, and display all data on the web page. After
run this, the data have been inserted and displayed; however, it give us a
warning message Warning: MySQL: Unable to save result set in . . I
test the same scripts in many other servers with MySQl 3.22.23,(BSD) ,
MYSQL 2.23.36(Linux), there are no errors or any warning messges at all. Is
there a way to reconfigration MYSQL, or PHP to eliminate this problem. The
following is a typical test .php:
to run this sript, you just create a table call user on your test database.

If credit card numbers are encrypted then the employees will have to take a positive step to steal credit card numbers. They won't be able to simply jot down numbers out of the data they have available. For example, if an individual gains the ability to execute SQL statements on your server, but doesn't have file access. If the credit card numbers are stored plain then they can gain access to them. If they are stored encrypted then the data is of no use without the key. So, overall, I'd say: Don't hassle with encryption: It's not worth it. I would counter that symmetric encryption is reasonably easy to implement and provides a modicum of security, so why not go ahead and do it. Just don't be fooled that a determined individual won't be able to defeat your encryption. It's rather like HTTPS encryption.

The directory is /usr/share/mysql I want to set the port and create a table. I know the comand to create a table, insert data and so on... But I dont know how I can start the client to do the table.

I need help constructing a search thingy using % _ in LIKE
Hi all, I have a problem, I have some VARCHAR data in a column called Sequence looking like this:- 5;6 12;6 120;6 5;6;1 12;6;12 120;6;105 So there could be anything from 2 to n numbers seperated by ; Each number could be 1 to 3 digits long (eg 5 12 or 121). I have tried various searches like the following but none of them seem fool proof, i.e. they miss data:- # This is for the maximum of 3 sequences searching by the 1st icon SELECT Sequence, Message, id FROM $sqlTable WHERE Sequence LIKE '$filterValue;%_%_' ORDER BY Message; # This is for the maximum of 3 sequences searching by the 2nd icon SELECT Sequence, Message, id FROM $sqlTable WHERE Sequence LIKE '_;$filterValue' OR Sequence LIKE '__;$filterValue' OR Sequence LIKE '%;$filterValue;%' ORDER BY Message; # This is for the maximum of 3 sequences searching by the 3rd icon SELECT Sequence, Message, id FROM $sqlTable WHERE Sequence LIKE '%;%;$filterValue' ORDER BY Message; 'Sequence' is where the numbers to search on are stored. $sqlTable is a variable containing the name of the table. $filterValue is a variable containing the search number. So what rules can I create to work for all examples, though the above examples are for only 3 sequences of ; seperated numbers, there could be upto 6 (though I would prefer a rule to cope with n amount). I am using perl so the OR LIKE part could be created PRE SELECT and then added onto the SELECT statement. This one is hurting my head.:-) M. -- Work:- postmasterAThinwick.demon.co.uk WEB:- http://www.hinwick.demon.co.uk Work:- mworsdallATshaftesburysoc.org.uk REPLACE AT with @ Home:- hinwickATworsdall.demon.co.ukWEB:- http://www.wizdom.org.uk Shadow:- webmasterATshadow.org.uk WEB:- http://www.shadow.org.uk - 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?

Slave thread terminating
Hi all, I am currently researching an issue with slave thread terminating when an error occurs. background: Win2000 server SP2 MySQL server/client ver 3.23.38 MySQL ODBC ver 2.50.33 Program language Clarion 5.5 Our database program can insert and update records without a problem. When a new record is added to the database it flows through to the slave ok. When we change a record, the master bin-log shows an INSERT statement instead of a UPDATE statement to the slave. This causes a error with the slave thread which is cannot insert duplicate key and the slave will terminate. I am looking for a solution which will log the error, skip the error line, and restart the slave itself automatically. Is it possible to set the SQL_SLAVE_SKIP_COUNTER=1 permanently and make the slave thread go again after a retry? Another approach could be to monitor the slave thread and run a batch file with the above commands in it. Any help on the above issue would be greatly appreciated.

Re: mysql and credit cards
You can always degrade the credit card. 1) verify AUTH ONLY (not capture) with your CC provider. (if you want to verify they have funds available and the CC is valid) 2) store the CC # in the database 3) ..do your order processing thing or whatever you need to have the CC for... 4) capture funds 5) degrade card value in the DB That seems to work well for non recurring credit card transactions (ie single purchases) Bill Elvis Gibbs goEbusiness.com - putting e-motion in your business email - [EMAIL PROTECTED] work - 301-668-5090 cell - 301-748-6938 On Wed, 25 Jul 2001, Steve Brazill wrote: AND, you'd want to 'protect' the data from viewing if you've 'dumped' the database or backed it up to an 'insecure' media or location (to tape/disk)...

And that's quite simple: a) You need to get access to the MySQL server. Impossible to do from the outside if '--skip-networking' is used. b) So, only possible from the localhost. This means, there must have been a break in to the MySQL server. Once he's on the server, he can do anything he likes. He can also read the source code of your PHP/PERL pages. There the password will be stored, somewhere. Once the password has been found (which is nothing but a matter of time), your encryption is broken. I respectfully disagree with this assessment. Encrypting data in a database can be useful, even if the key is relatively easy to find. The situation you describe is one of a determined individual trying to gain access to credit card data. This is indeed the most difficult type of person to prevent gaining access to your data. If they are able to compromise your system then they will be able to decrypt the data in the database and get the credit card numbers. However, encryption prevents casual viewing of credit card data and prevents the discovery of credit card data if a secondary system is compromised. For casual viewing, you may have employees who have access to the database for the purpose of fulfilling orders or contacting customers. If credit card numbers are encrypted then the employees will have to take a positive step to steal credit card numbers. They won't be able to simply jot down numbers out of the data they have available. For example, if an individual gains the ability to execute SQL statements on your server, but doesn't have file access. If the credit card numbers are stored plain then they can gain access to them. If they are stored encrypted then the data is of no use without the key. So, overall, I'd say: Don't hassle with encryption: It's not worth it. I would counter that symmetric encryption is reasonably easy to implement and provides a modicum of security, so why not go ahead and do it. Just don't be fooled that a determined individual won't be able to defeat your encryption. It's rather like HTTPS encryption. It's a first step that prevents casual peeking at the data which is being transmitted between a client and the server. However, it does not prevent a determined individual from seeing the traffic.

In my reading, I have not encountered a TYPE of ip_address or some such. Did I miss it? If there is no such type, what would be the best way to setup the addressing for the fastest possible locate?

Re: Mysql dumps FTP
Since the dump is ascii text with lots of repeating characters, it should zip or gzip quite nicely. The compressed file will take a lot less time in transfer over FTP, if network time/bandwidth is a problem. This becomes important when doing over-WAN stuff. The time involved for 1-3GB arch logs (compressed), if I remember, takes a number of hours to compress and up to 3 days to send over a 100kbps WAN across the world. Oracle arch logs don't compress (maybe they are already compressed?).

Re: Question on design
I would suggest that you use an INT column type to store the ip address. This would use a lot less space than a varchar column (when dealing with the magnitude that you describe)... the smaller the faster... The following functions make this very easy: INET_NTOA and INET_ATON They are described on http://www.mysql.com/doc/M/i/Miscellaneous_functions.html Because the entire address is stored in one INT field if you wanted to do any kind of select based on subnet you could use bitfield operations.

Importing a text file into Mysql
Hi folks. I have a local Access database here which I have created tab seperated text files of each of the tables from to import into the Mysql db we are running on our ISP's server. However I have one field in one of the tables that is a text file and contains sometimes very long descriptions of a particular item, depending on which record it is. Now every time I import my text file (using phpmyadmin) when it gets to this particular field in certain records where there are a couple of paragraphs of information it inserts the first line of information. But then nothing else into this field. I'm pretty sure the import is chocking on the carriage returns used in the longer descriptions in some records. Does anyone know a way of getting around this problem and getting it to import properly. Basically the settings I use for importing are: Records seperated by tab, nothing is used to identify text and // is used to escape characters. Any hints would be much appreciated, and I can send samples of the import files if anyone needs to look at them to get a better idea. -- Duncan Pilcher Laboratory Systems Co-ordinator Analytical Reference Laboratories 5 Leveson St North Melbourne Victoria 3051 Ph: (03) 9328 3586 Fax: (03) 9326 5004 Email: [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?
