MySQL University session on Feb 19: Developing MySQL on Solaris
Developing MySQL on Solaris http://forge.mysql.com/wiki/Developing_MySQL_on_Solaris This Thursday (February 19th, 14:00 UTC), MC Brown Trond Norbye will give a MySQL University session on Developing MySQL on Solaris. MC works on the MySQL Documentation Team and has been involved with quite a few Solaris things, for example porting MySQL to openSolaris. Trond has been involved with many things, including openSolaris, as you can see from his blog (http://blogs.sun.com/trond/). For MySQL University sessions, point your browser to this page: http://webmeeting.dimdim.com/portal/JoinForm.action?confKey=mysqluniversity You need a browser with a working Flash plugin. You may register for a Dimdim account, but you don't have to. (Dimdim is the conferencing system we're using for MySQL University sessions. It provides integrated voice streaming, chat, whiteboard, session recording, and more.) MySQL University is a free educational online program for engineers/developers. MySQL University sessions are open to anyone, not just Sun employees. Sessions are recorded (slides and audio), so if you can't attend the live session you can look at the recording anytime after the session.

Re: SPARC to x64 Transition
Aaron, I've currently got a project to migrate a LARGE (3.5TB) MySQL data set from a Sun SPARC machine to a Sun x86 machine, both running Solaris 10 (though obviously one is x86 and the other is SPARC). Is it possible to simply copy the data files from one host to the other or is a full mysqldump/import necessary to preserve data integrity? If a file copy doesn't work, why specificially would it fail? Thanks, -Aaron you can simply copy the files, whether InnoDB or MyISAM. As far as I know, all modern processors use the same floating point format. And all integer and other data structures are platform independent in MyISAM and InnoDB.

what is best upgrade plan for large, replicating database?
I am beginning the process of upgrading a large mysql 5.0 database to 5.1. Specifically, I'm going from 5.0.56 enterprise to 5.1.30 community (which I think is now the GA version?) The db is about 4 terabytes. This means making a dump of the database, installing a new version of the dbms, and reloading the database, would take too long. Also the databases are replicating. I believe I need to upgrade the slaves first, the go to the master. I've read about the possibility of having to rebuild indexes, mainly due to collation changes. I didn't see any compatibility issues in going to 5.1.30, although I can certainly rebuild some indexes if I need to. Can I (after backing up the data) just install the new mysql code, run mysql_upgrade, and reasonably expect the database to work? What is time involved? If I can just install new binaries and point them to the old data, the time taken should not depend on the size of the database, should it (unless I have to rebuild some indexes)? Thanks, Jim -- Jim Lyons Web developer / Database administrator http://www.weblyons.com
Re: what is best upgrade plan for large, replicating database?
Jim, In my experience updating the binaries (or installing the new ones in addition to the old ones) works fine as long as you have made sure there are no incompatible changes. I have done this from 5.0 to 5.1 without any issues. Just run mysql_upgrade and you should be fine. I have never had to rebuild my indexes so I am not sure about that Olaf On 2/16/09 12:28 PM, Jim Lyons jlyons4...@gmail.com wrote: I am beginning the process of upgrading a large mysql 5.0 database to 5.1.

accent sensitivity in fulltext search
Hi,
How can I have accent sensitive, case insensitive fulltext query?
version: 5.0.45
The database, tables, connection, data etc. are all utf8.
select name from people where match(name) against ('königsberger' in
boolean mode);
shouldn't return konigsberger.
Any idea, collation?

Slow connection over VPN
We have an application using mysql. When we run it locally there are no issues. If we try and connect to a remote database machine over VPN it works but takes a VERY long time to get anything done. We are using the exact same database. All other programs using the same VPN run fine and the speed on the VPN has tested fine. Does anyone have any ideas?

Re: accent sensitivity in fulltext search
Hi,
try to set the collation to utf8_unicode_ci.
I have had the inverse problem and I solved with utf8_general_ci.

Re: accent sensitivity in fulltext search
Thanks Santino, but unfortunately didn't help .
I tried utf8_bin, just for checking, same results¸
Not even the case sensitivity is respected.
The following queries return the same results:
select name from people where match(name) against ('königsberger' in
boolean mode);
select name from people where match(name) against ('koNigsberger' in
boolean mode);
Königsberger
konigsberger
Could it be a version dependent problem?

how to deal with multiple authors for one book
In my db there are a number of books with several authors; so, I am wondering how to set up a table on books and authors to be able to insert (via php-mysql pages) data and retrieve and display these books with several authors I suspect that to insert data for a multiple author book I will have to enter all data other than the author names into the book table and enter the authors in the author tables with foreign keys to reference the authors and their book. Then to retrieve and display the book,I would have to use some kind of join instruction with a where clause(regarding the position - 1st, 2nd, 3rd...) to retrieve the authors and their order. The order would probably be done by a third field (e.g. f_name, l_name, position) in the book_author table (tables in db - book, author, and book_author) Am I on the right track, here? -- Phil Jourdan --- p...@ptahhotep.com http://www.ptahhotep.com http://www.chiccantine.com -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/mysql?unsub=arch...@jab.org

how to check for null in string
I know this is not working, but how can I check for NULL; or how can I
configure my field sub_title so I can check if $booksub_title contains
anything or is empty.
This problem as been breaking my back...don't know what to put in as a
default to be able to check against string input (VARCHAR) or should I
use another type?
if ($booksub_title != NULL) {
echo td width='400'b$booktitle[$i]/bbr
$booksub_title[$i]/b;
}
else {echo td width='400'b$booktitle[$i]/b;
}
