One Slave Many Master
I know someone already ask this, and the answer generally 'NO YOU CANT' :b but, is there any work around so i can make a backup server (slave), from many other server (master) through replication? well, it's not just a backup server actually.. it really is the headquarter's db server, and the branch offices can not directly post their transaction.. because the line is teriblyy sllw :D so, im thinking of adding extra server on branches and replicate what ever happens there to the main server perhaps, if i can run multiple mysql server on different port on the main server, with it's own database, that act as a slave one to one to other server, and add one more that handle all of the DB .. Main ServerBranch ----- DB1, 3306 DB1, 3306, BranchServer1 DB2, 3307 DB2, 3307, BranchServer2 DB3, 3308 DB3, 3308, BranchServer3 DB4, 3309 DB4, 3309, BranchServer4 and so on... MASTER DB(DB1,DB2...DBn) on port 33xx is this possible??? or maybe there are other solution.. pleasseee.. i really appreciate it oh, one more thing, can the replication run both way? what ever happened on machine A, replicated on machine B and vice versa.. thanks... -- Regards Leonardus Setiabudi IT Project Coordinator PT Bina San Prima, www.binasanprima.com

Re: Forms Reports like I use in MS Access
Me I use VB for the front end development and MySQL for the database. I use ADO to connect to the database through MyODBC. When you use VB to connect to a MySQL database, there are two things that will change: * the connection string * the cursor location will be set to adUseClient. Read the MyODBC manual and you will get enough information about how you can use VB with MySQL. Also, consider joining the MyODBC mailing list.

You could use Access. ;-) MySQL is a database; Access is a database with a form and report designer. With MySQL you can use any front end you like that can 'talk' to the database engine. In my case, I used Visual FoxPro for many years, because of its pure object-oriented design tools, but I got tired of being limited by the file-based data access of products like VFP and Access and the limited security of those products. I now use VFP as the front end and MySQL as the back end exclusively, and my apps are better than they ever were. I have a powerful object-oriented design tool that allows me to create not only the GUI for my apps, but also has the power to create a strong middle tier of business objects that contain the logic that governs the data. I'd recommend VFP, but if you are already fluent in Access, you would probably be better off using that for your GUI. You connect to the data via ODBC or OleDB, and then use the data normally. And if you ever move away from the world of Windows development, there are several choices on Linux and OS X that I'm sure others will chime in with. ___/ / __/ / / Ed Leafe Linux Love: unzip;strip;touch;finger;mount;fsck;more;yes;umount;sleep -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED] -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
Re: newbie question about calculations
Why do you want to store the results of a calculation? Don't store the results of a calculation, instead do the calculation when you are retreiving data. For example SELECT field1, field2, field1 + field2 AS sum_of_the_two_fields FROM your_table Also, it is a good idea to give good names to your fields. Not Field1, Field2, Your names are very confusing. It is like giving birth to three boys and you name them Boy1, Boy2, Boy3 Would you do that? The last question will be why you defined the fields as VARCHAR while it seems they will be holding numeric values. If the will be holding INTEGERs or FLOATs, define them accordingly. The manual will easily teach you about the data and field types.

Re: Core Certification
Hi Arjun, I have taken both exams (July and August 2002). The best advice I can give you is to get your hands on the Mysql Certificate study guide coming out in 2 months (from Paul Dubois). I had the chance to preview bits of it and I believe that it will be a VERY good help. Just read through it carefully and playaround with the system at the same time to practice the read things. The exam which I was taking was beta at that time. It was hard but fair I felt. Take your time when reading the guide question the details mentioned (or not) in the book to get a really good grasp of the subject. Thats the best you can do, do get into the exam relaxed and without any unneccesary pressure.

Re: MySQL 5.0.0 has been released
Hi, First of all, thanks a lot. I have installed MySQL 5.0.0 on my test machine (Suse Linux 8.2 kernel 2.4.20 i586) and have populated data (~40 InnoDB tables with max. 50 000 000 rows) So far it works stable and I didn't have any big problem, but I have found that speed of inserting data is ~3-5 times slower in comparison with version 4.0.14 (the same my.cnf config-file and the same PC). Is it because binary distribution of 5.0 version is not optimized? Thank you in advance, Mikhail.

Re: Not able to connect to mysql by mysql_connect()
If you are the one controlling the MySQL server, do one of the following:
1. Shorten the Password Column of the mysql.User table
2. Change your password to use the old passwords (you may use SET
password=OLD_PASSWORD('your_password');
3. Put the option --OLD-PASSWORDS in your options file
4. Update the User table using the OLD_PASSWORD() function [for example
UPDATE mysql.User SET password=OLD_PASSWORD('your_password') WHERE
User='your_username' AND Host='your_host']
Just do one of the above and your problem will be solved until PHP releases
a version that supports the new authentication protocol used by 4.1
Also, reading the manual will give you more hints.
Thanks

Re: extending a database over several servers
Yes and no.. mySQL itself cannot do this.. If you need to keep growing in size (on 1 server) you may want to look at some kind of LVM disk array/SAN you can keep plugging in disks and extending the volume.. I do kinda of what you are looking for with 1 application, but it is all software controlled, mysql has no knowledge it's happening. There is 1 controller sql server that controls all the storage, it knows of multiple other sql servers and decides where to store data and where all the data is for retrevial. You need more storage, plug in another server, tell the controller it exists and it will start filling up with data and serving requests for that data.

Newbie Question - can I collapse these two queries into one line?
MySQL Gurus, Hello, I am new to this list. I have looked through the archives and online, but the particulars of my situation still leave me perplexed as to how to solve this. It may be more of a lack of ability to logically sort my query than it is an issue of syntax. I have three tables. One records members and information about them, such as their email addresses. Another table keeps track of classes that the members attend, and in that table is the date of the classes. The third table records when a member is attending a class. What I want to be able to do is select all the email addresses of all the students who attend a class on a particular date. If I do it as a two step process in PHP, it works: $wsQuery = SELECT improvwsid FROM improvws WHERE wsdate ' . $today . ' AND wsdate ' . $sevenDays . ' AND cancelled = 0; $wsResult = mysql_query($wsQuery); $wsid = mysql_result($wsResult, 0, improvwsid); $emailQuery = SELECT members.email AS email, members.firstname AS firstname, members.lastname AS lastname FROM members, improvwsattend WHERE members.id = attend.attendeeid AND attend.improvwsid = . $wsid; $emailResult = mysql_query($emailQuery); While this is getting the job done, it doesn't sit right because it feels like I'm being inefficient. There must be a way to get the results I want in one query. But not only can I not figure out how to do that, I'm at a loss as to how to describe where my thinking is going wrong. Any help would be much appreciated. -- Yoroshiku!

Re: Cannot connect on the internet...Do I need to open a port on my router?
If remote clients will connect directly to your MySQL server then you will need to open port 3306. If you are only going to access MySQL via server side scripts (PHP) then you will not need to open this port as the scripts will connect to the localhost. If you cannot see your web site then it sounds like a configuration problem with Apache. You might check your Apache config file. You might also check your firewall and router settings to make certain that port 80 is open. -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

For instance: SELECT * FROM EMPLOYEES WHERE last_name LIKE ? + % ? means parameter Are you sure you want to add two strings together? That's a math operation, and you'll just get zero. You probably want WHERE last_name LIKE concat(?, %) or WHERE last_name LIKE ? , and make sure the string you're passing in has a % at the end. Note that only MySQL 4.1 and above truly support parameters (aka bind variables); if you're using mysql 3.23 or 4.0, your language's database API will have to expand them before sending the query to mySQL. -- Dan Nelson [EMAIL PROTECTED] -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
MySQL/InnoDB-5.0.0 is released
Hi! Due to Christmas, this release note comes late. For MySQL users release 5.0.0 is a milestone: you can now write stored procedures in MySQL. InnoDB in this MySQL release is essentially the same as in 4.1.1, with the bug fixes of 4.0.17 included. Later 5.0.x versions will probably include new space saving table formats for InnoDB. IMPORTANT NOTE: if you upgrade to InnoDB-4.1.1 or higher (like to 5.0.0), you cannot downgrade to a version lower than 4.1.1 any more!

Re: INNOB error and mysql won't start
Hi! I accidently deleted the ibdata and iblogfile files. InnoDB: Error: log file ./ib_logfile0 is of different size InnoDB: than specified in the .cnf file! You really have not deleted the ib_logfiles from the MySQL datadir. And probably not the ibdata1 file either. If you have already valuable data inserted, best to edit my.cnf so that it agrees with the real ib_logfile size. Or, if you can start from scratch: http://www.innodb.com/ibman.php#Wrong_creation If something goes wrong in an InnoDB database creation, you should delete all files created by InnoDB. This means all data files, all log files, the small archived log file, and in the case you already did create some InnoDB tables, delete also the corresponding .frm files for these tables from the MySQL database directories. Then you can try the InnoDB database creation again. It is best to start the MySQL server from a command prompt so that you see what is happening.

Re: Redhat crash - help needed
Hi again, sorry for replying to my own message, but I found the [obscure] problem. turns out mysql doesn't like getting its gid information from an LDAP server. There is no mention of this in any of the docs I found, but I will do more looking this morning. The solution was to change my nsswitch.conf file from group: files ldap to group: files and this solved things. I think this is dumb and should be fixed/changed in mysql. I now have to have my group definitions on every system, even though the information for users is taken from LDAP. (and yes, I've tried simply creating a local group/user for mysql, but to no avail - so long as the group line contains ldap in nsswitch.conf, mysql falls over). -Dan On Mon, 29 Dec 2003, Dan Goodes wrote: Hi folks, just compiled up mysql-4.0.17.tar.gz on a (stock, basic install) RHEL3 system, and get similar symptoms to something I experienced a while ago with RH9. that is... it compiles fine, but wont start.

That column gets converted to be readable. My problem is I have many rows that need to be updated, but I dont want to re-convert the times that have already been converted. I know from about 61500 and up that the records are partially updated. mysql select start from table where ID =61500; +-+ | start | +-+ | 2003-12-28 00:45:16 | +-+ 1 row in set (0.00 sec) mysql mysql SELECT start,ID FROM table ORDER BY id DESC LIMIT 1; ++---+ | start | ID| ++---+ | 1072603517 | 617168732 | ++---+ 1 row in set (0.01 sec) mysql So now I want to run my update statment, how do I not update the times that have been converted??? Help my current update statement: from script: OID=`echo select ID from $TBLE order by ID desc limit 1; | $MSQL -u$UI -p$PD -h$HT $DB|grep -v ID` echo update $TBLE set start = from_unixtime(start) where ID '$OID';| $MSQL -u$UI -p$PD -h$HT $DB Thanks for your help up front Rob -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
left join-ing for two values
hi how do u create a query to select two diff values of the same column from another table using a left join? i know i'd retrieve them with aliases but where do i set which alias is for which value? here's a simplified version of the tables table1: colours id colour table2: choices id old new old and new are both ids in the 'colours' table. what i wanna do is something like: select id, colours.colour as old1, colours.colour as new1 from choices left join colours on colours.id = old... now here, can an and clause be used so it reads on as... and colours.id = new or do i put another left join? either ways, how do i specify which join / equality is which alias or whateva? i don't wanna use two queries...as far as possible. ty abs ps: i wouldn't be going through all this just for colours ;-) also (unrelated to mysql) ;-) i didn't know that pink's song feel good time is from charlie's angels 2. just saw the video on mtv and realised. my question: the rythym guitar, bass and to some extent, the lead guitar are playing this tune throughout the song, any idea which song it's from? i don't think it's original to that song, anyone know where...?

5.0 binary question
I downloaded the 5.0 preview alpha binary for Win32 and installed it - so far, so good. But I don't see anything in the doc on the stored procedure capability (how-to/syntax) and I can't create one within 5.0 (using SQL99 syntax - at least I think/hope so). Is stored procedure capability not available in the provided binaries (maybe it's only in the source tree?)? Just want to make sure I'm not missing something. Thanks, Rick

java APIs v.s. c APIs

Thanks, chasee Connector/J does not use the MySQL C-API, however it exposes most of the functionality in a JDBC-like way. Funtionality such as mysql_last_insert_id() _is_ exposed via the JDBC-3.0 Statement.getLastGenerated() keys method, or via a 'custom' method of com.mysql.jdbc.Statement.getLastInsertId(). Other MySQL-specfic functionality is exposed in a JDBC-compliant manner. You will have to specify _which_ functionality you're looking for to get any more specific answers (or look in the README for Connector/J).

Log Files in MySQL
I think I am confused. I have many bin index files, but I have not gotten rid of them. I read somewhere that I should not remove them...or I should not remove the entries in the index file. Since I am unsure of which one above is correct, I am posting to the list. Can someone let me know which of the above is correct, and what I should do?

RE: 5.0 binary question
Hi Mikhail- Thanks for responding; the presentation is very helpful; However, I think I may not have been clear enough - I was asking whether the binary alpha 5.0 that is now available from the web site had stored procedure support. I don't think it does as I don't see a catalog table mysql.proc defined and I cannot create any procedures. It's a little odd that 5.0 would be made available as a binary without the primary feature to exercise built into it. Oh well. I still feel like I'm missing something because that just doesn't make sense.
