RPM help
This is really a question of RPMs (though it arises because I'm eager to move from MySQL 4.1 to MySQL 5). If I knew the correct place to post the question, I would probably know where to find the answer. I do suspect that it's a FAQ, but I haven't found the right search terms. I'm using SuSE 9.3 (not the Enterprise Server), and I would like to upgrade from MySQL 4.1 to the latest stable version. There do not appear to be SuSE rpms for 5.0. I'm happy to build and install MySQL from source, but I would like to integrate the fact of that installation into the RPM database. I'm sure that there are tools or instructions on how to do that, but I haven't found any yet. Thanks for any help with this.

Re: MySQL 5.0 character sets

I like MySQL very much, I'm using it since 3.x versions, so I think I know it very well. But... I'm new to everything, but I can tell you what I think that manual says. character_set_client | latin1 This is, what the client thinks about itself, determined from the environment. It will be used for autoconverting character data sent from the client. It is what the client tells the server about the queries that the client sends. character_set_connection | latin1 This is, what the client thinks about the server, but I'm not sure, how it will be determined, and what exactly is it for. As the documentation says, it will be used for autoconverting character data sent to the server. It is what the server uses internally. The server will convert queries from character_set_client to character_set_connection character_set_database | latin1 It's the general database default character set, used when you create a table. No more additional meaning. ? That is my guess. character_set_results| latin1 It is, what the client thinks about itself, and will be used for converting character data coming from the server. When the server sends results to the client it will send the results in character_set_results. That is the server will convert from character_set_connection to character_set_results when sending results. character_set_server | latin1 Pass. Fogolmam sincs. (I can't figure it out from the documentation either). character_set_system | utf8 Pass. Sincs (nor here). And another strange thing I found: you can set the table's (default) character encoding, but I see no effect. The table data - of course - won't be converted (that's another alter table command), the results I got won't be changed - so I don't know, what exactly default table character set is good for. I've also been having some difficulty with this. I recommend using utf8 for everything, unless the window in which you run the client can't handle utf8. Remember, those accent marks matter. After all Szárba szökik just isn't the same without them.

Re: Map of MySQL Users

Hmm. That located me perfectly, but on the map, I was off by 2000km. However, I had just updated my location (deleted my entry and then created a new one with my correct address), so if that fed back into the location system, that might explain it.

Turning tables on their side
I suspect that this is the wrong list for this kind of question, but if someone could point me to appropriate sources, I would very much appreciate it. I am new to SQL but inherited project designed by someone who doesn't seem answer his email anymore. Essentially date were collected on the web using PHP inserting things into a MySQL data base. It took me time, but I now have a handle on what is in which of the 15 tables involved. Each response to each question by each respondent produced its own record (row). That is, I have something like respondent_idquestion_id answer_id answer_text 23 201 56 NULL 23 202 20 NULL 23 203 1 NULL 23 204NULL Arlington 24 201 52 NULL 24 202 21 NULL 24 203 0 NULL 24 204NULL Richmond and so on for other respondent_ids as well. What I would like to get for my users is something that looks like respondent_id q201 q202 q203 ... --- 23 text-for-ans56 text-for-ans20 text-for- answer1 ... 24 text-for-ans52 text-for-ans21 text-for- answer0 ... So instead of having a record for each response, I'd like to have a single record for each respondent that shows all of that respondents responses. For someone who knows SQL this should be easy. I suspect that a group by respondent_id clause will play a role, but I just don't see it. As I said, references to books or sites that I should learn from would also be welcome. -j -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

What you are trying to do is store the data as you see it, which is rarely a normalized data model. Your presentation layer should handle the formatting for the user. I'm sorry that I didn't make the question clear. My goal is to export an MS-Excel file that looks like my target. I do not wish to change how things are done in the DB. The end-users will want a spreadsheet like that for doing their analysis. Not for queries. I'm using phpmyadmin which will do an Excel export of a table for me. I just need to create the temporary table long enough to do the export. -j -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

That snippet of sql code will help you get one answer from the 2 the original database had. Thank you. I can immediately see several places where that will come in handy Unless there's ever an answer_id AND an answer_text, although the example doesn't support that. Well, there shouldn't be any cases like that, but I'll can run a quick query to check.

Re: Encryption for mySQL 3.23
On Oct 4, 2005, at 4:34 PM, Jeff Pflueger wrote: Where might I find the key so that I can send it along to them? any suggestions on this? The password is what you need to send. The encryption and decryption functions generate a key from the password. Internally, the key that the AES/Rijndal algorithm uses is a 128 bit (or 256 bit) sequence, but the AES_ENCRYPT() function will convert the password (in a deterministic way) probably using a hash function such as SHA-n or MD5 into a 128 bit sequence. If you could describe a bit more fully what it is that you are trying to achieve we might be able to suggest alternative strategies that will better meet your needs than encrypting particular fields this way. -j -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
Documenting and visualizing a database
This is probably a FAQ, but I haven't been able to find the answer. Briefly, I am looking for tools that will help me document a database. Visualization would be nice too, so that I could quickly see the relations between tables. Less briefly. I am new to MySQL, SQL in general and databases. I have inherited a project that uses, Apache, PHP, and MySQL. The MySQL Press book, MySQL Tutorial has been extremely helpful. My predecessor, who did know something about MySQL, left no documentation. As I am trying to figure out what is what and what the relationships are between tables, I've got paper and pencil pictures, and a text file full of notes. But, mostly it is just an understanding -- for the parts that I understand -- in my head. Now I can always redraw my paper and pencil stuff with something like xfig, but it struck me that there is probably a standard, well conventional, notation for this kind of thing and tools for the purpose. I'm a bit of a geezer and my memory isn't as reliable as it used to be. Plus, I don't want any successor on this project to curse me quiet as vehemently as I curse my predecessor. So advice or pointers to advice would be very welcome. As for tools, I'd be looking for things that can run on Unix systems (GNU/Linux and/ or OS X). If I've hit the wrong list, I sure someone will tell me where to go.

Re: Documenting and visualizing a database
On Sep 25, 2005, at 5:44 PM, Robert L Cochran wrote: I would start by writing down what you believe the database consists of: 1. The table structures -- write them down, commit them to paper. Thanks, I've already printed out all of table structure information. 2. The relationships you believe exist between the tables. Document them in writing and visually. That is what I have started to do. Because the stuff that I was writing down seemed, well, fairly structured, I'd assumed that there were some useful conventions for recording these. Use whatever tool works for now -- don't make the mistake of allowing the tools to stand in the way of proper documentation. Of course. But I was hoping that existing tools might remind me to note down things that I might not have occurred to me to note down. Now look at the code components. 1. Print and organize all the code that exists. 2. Study the code; determine how each component relates to the others. Diagram this program flow as above for the tables. Don't let lack of software stop you. Pen and paper is better than exactly nothing. I wasn't looking for software for this part, though something like ctags for PHP would be nice. After printing everything out, the next thing I did was put things under revision control. As to learning MySQL and PHP, there is really only one good technical writer for MySQL: Paul DuBois. His book MySQL 3rd edition is a must-read. Thanks. But even Paul is not a magician; you can't learn MySQL from a book alone. You need Paul's book, and the willingness to practice working with MySQL. Of course. The Tutorial from MySQL AB requires that. And I've successfully added some new required things to the project. Of the various PHP writers, I really have great respect for Tim Converse and Joyce Parks. Again, thanks for the recommendation. But I'm still left puzzled. If people haven't developed tailored tools to document a database, then I find more than a bit of irony in the fact that people who specialize in organizing data in useful ways would not have developed a way to organize data that they need to make use of on a daily basis.
