Re: Help somehow turn this into a single query
Ken writes: Query question: Can anyone think of a way to accomplish this in a single query?: I have a table with elements that each have a date.

Do it in two queries or be prepared to take a performance hit. Honestly I can't even think of a way to do it with just one query, but looking into using SQL variables might help.

RPM or SourceCode ???
Hi all I was just getting thru the documentation of MySQL at the mysql.com site and there it is specified that The recommended way to install MySQL on Linux is by using an RPM file Can anyone tell me in what way it is different installing mysql from the rpm's and from the source code ?? except that if we install from the source code it is a bit tedious where as with the rpm it is convineint. Are there any reasons other than this ?? i for one feel that installing from the source gives us a lot of options and flexibility thanx in advance. cheers !!

Corrupted tables -- for 'no apparent' reason
Hello, We are using mySQL on over 6 servers here, we have been doing so for over 2 years, and we are constaly facing problems with corrupted tables, especially on two of our busiest servers. Tables seem to corrupt out of the blue and we have to shut them down ( the servers ) occassionaly to fix all tables and then bring them up again. This is really not something we want to do, bringing down a server that is, so we were wondering if we are doing something wrong. There must be other users of mySQL using it for far most difficult tasks who maybe faced the same problems once but managed to solve them. We are using mySQL 3.23.41. Tables corruptions occur regardless the server's configuration ( even on a system with PIII@1MhzX2 with 1.5G RAM we get those problems ) so maybe there is something wrong with the startup options we are using for mySQLd. This is how we start mySQLd. --skip-locking -O back_log=1024 -O table_cache=280 -O max_connections=2048 -O wait_timeout=30 -O interactive_timeout=30 -O long_query_time=2 --log-slow-queries=slow.log --big-tables Please reply to [EMAIL PROTECTED] Thank you in advance, Mark Papadakis - 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?

If not, someone should really think of adding a section to the Functions area to list out all of the aggregate ones. Probably a good idea if they aren't already clearly labeled in the manual. On that note, I'm curious if there is an aggregate version of CONCAT or CONCAT_WS (and if there isn't, make a suggestion for the creation of them). Something like join() in Perl, maybe? I'm not sure quite what you're looking for. Can you give an example of where/how you'd use it? It might also be nice for whoever writes the manual to include the minimum MySQL version supporting the function (my ISP is still using 3.22 and it's annoying to learn of a cool function only to find out that it doesn't work when I try it)... That's in the manual sometimes, and sometimes not. What you really need is the manual that comes with the 3.22 distribution. Then you won't have that problem. What you really need to do is get your ISP to jump into the year 2001 and upgrade. But you already knew that. :-) Jeremy -- Jeremy D.

Re: command line open source ARRRGGGGGG!!!!!!
Chadrick Mahaffey wrote: what does all this mean? I tried to type this in my command console changin / to \ and I don't understand what is happening. I get all kinds of errors. It looks to me that you're trying to use the Unix install notes - don't! Refer to section 2.1.2 in the excellent manual, (worth downloading so you've a local copy). Open source would go much farther if they had self explanatory GUIs and had basic pre-setup apps that were ready for the average user to use. Why? Maybe I'm really offbeam, but I'd suggest that MySQL is more of a server product than one which should reside on the desktop. Further, why then saddle the server admin with a GUI. In my experience even the best GUI is not as flexible as a half-decent command line installer. A GUI is fine if you've to install on just your PC, but there's no way I'd be happy if I was doing multiple installs - at least with the command line you can make a small (one-line?) batch file to do the job on however many systems you have. I could be mean and turn this on it's head - if you want a GUI, do it yourself and then contribute it back! Most open source apps I have attempted to use have some of the worse documentation around. The writers assume so much about the users. You've been very unlucky then. Nearly all the major apps, (and most of the smaller ones), have excellent docs, simply because the vocal user community wouldn't let them away with anything else! (If you don't like a bit in the manual rewrite it and submit it back ?) That said, I will agree slightly in that some of the app docs are very Unix-centric (not MySQL's), and I personally find the Apache manual a bit hard to use. For your core apps it's probably worth getting one of the 3rd party books, (the MySQL one is very good indeed). OK - call me inept, stupid, or whatever but I had to say it. Fair enough - you're stupid! ;-) Quote for you real stupidity is quite rare, (except in politicians where it seems to be a qualification), and what is generally perceived as 'stupidity' is nothing more than inexperience, can't remember who to attribute this to, but it seems pretty apposite. As to MySQL I'm just past the caveman stage myself. Keep in there and it'll all fall into place, (with a bit of help from this mailing list), and then who knows?

information about deiferences oracle/mysql
Hi guys, I'm just a student, working on a project. We have to migrate a oracle database to MySQL. In order to do that we must search for diferences between the two and for other information that can help us. (of course we're not allowed to just download software and convert) Now, I've allreaddy searched for 1,5 days but I only find, or to technical, or to extended or whatever, I can't vind what I'm seraching for.

Optimization question and possible bug
Hi, i'm using MySQL 3.23.37 on a Linux system with an average of about 20 queries/second. First of all i have a little question how i can optimize a query. The query is like that: select * from tbl where key_field1 constant1 and key_field2 constant2 Examine that query with explain select... show that the indexes are not used. The keyfields are unsigned tiny int where every bit has a different meaning. Any clue how i can rewrite this query in a way where the indexes are used? In the database i have a merge-table that merges 10 myisam tables. Sometimes the loadaverage of the system raise above 50 and the long-query-log is filled with some query accessing the merge table. This happens 2-3 times a day. Only a minute later everthing is okay again without doing anything. I can't believe that it is a performance problem because there is a summary of only 10,000 entries in the merge table and 50,000 entries in other tables. Does anybody experienced this strange problem, too? The last thing i found is a possible bug in merge-table implementation of 2.23.41. After an update from 2.23.37 to 2.23.41 i got only the first row of the result set again and again. Maybe it's a communication problem between php (with included mysql interface) and the new MySQL version. (Haven't determined it yet).

RE: A question about load / queries pr second
Hi, About a year ago, I used mysql-super-smack and was able to hit 8,000 per second on our [then new] server. The highest I've recorded on an actual production application was around 5,000. But I don't watch the numbers closely very often... Just out of curiosity, on what hardware? This was Linux 2.2.x on a dual-cpu P3-850 with 1GB of RAM and 5 36GB SCSI disks. I'm quite surprised that this level of performance is available from such standard (well, not standard as in 'common', but y'know what I mean...) hardware. The last I heard, 1K+ queries/sec was only being done on extremely high-end Sun enterprise-level machines. On the other hand though, it gives me some comfort that the hardware being used in my operation will meet any future needs. We have similar spec servers (P3-1Ghz dual-cpu, 512Mb RAM, 3x36Gb SCSI RAID5). Maybe I should try out mysql-super-smack and see what kind of numbers it turns up. :-) Regards, Basil Hussain --- Internet Developer, Kodak Weddings E-Mail: [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: Problem with paswords
Any ideas?

Hi!
I've just installed (a couple of days ago) mysql.
I will use mysql for using with hlstats. That is
a stats-program for HalfLife Counter Strike. (game)
But I got errors... I guess it's a problem with mysql
or me not knowing how to do it.
Here is some printouts what I'm trying to do:
mysql select host,user,password from user;

+---+-+--+
3 rows in set (0.01 sec)
mysql SET PASSWORD FOR 'hlstats'@'%' = PASSWORD('test');
Query OK, 0 rows affected (0.00 sec)
(nothing changed but look att password below)
mysql select host,user,password from user;

ERROR 2003: Can't connect to MySQL server on 'localhost' (10061)
Hello, I am running version 3.23.41 on windows '98. When I run winipcfg I show that my hostname is siren.goldengate.net and my ip address is 10.0.0.1. When I type c:\mysql\bin mysql I get an error message: ERROR 2003: Can't connect to MySQL server on 'localhost' (10061) I tried several versions of -h switch: mysql -h siren.goldenget.net mysql -h localhost mysql -h siren but no luck. After much playing around with the scripts located in c:\mysql\bin I noticed that c:\mysql\bin mysqld-opt starts the daemon and then allows me to run c:\mysql\bin mysql to get in. I then need to run c:\mysql\bin winmysqladmin to shut down the server. This works for me now but I'm not sure if it will cause problems later. I can't tweak any of the scripts in c:\mysql\bin so not sure what other options I have. Is there a better approach than this kind of work around?

Subject: Problems retrieving tables
Can anyone help- I am new to MySQL.
I am using Ultradev. I have installed MyODBC on my PC and set it up
connect to my ISPs MySQL server.
The connection works OK.
I have successfully exported and imported tables from an MS Access
database on my PC.
When I set up the connection through the site on my PC, all works fine.
However, when I use the connection string
Driver={MySQL};Server=localhost;Database=dbname;UID=uidname;PWD=passwor
d
and upload the site to the web I get problems.
The connection seems to be OK, but when I try to get to the tables I get
the error message
'Unable to retrieve tables from this connection'.
Has anyone else encountered this?

Re: command line open source ARRRGGGGGG!!!!!!

These are the commands and instructions for installing MySQL on a UNIX box. They are UNIX shell commands, not Windows DOS commands. You need to find the commands and instructions for installing MySQL on a Windows box, if that's what you are using. cm Open source would go much farther if they had self explanatory cm GUIs and had basic pre-setup apps that were ready for the average cm user to use. I program in Java and I feel the same about the JDK cm Sun produces. I use JCreator because it has an easy to follow GUI cm interface. Most open source apps I have attempted to use have some cm of the worse documentation around. The writers assume so much cm about the users. OK - call me inept, stupid, or whatever but I had cm to say it. Open source software is written by technical people. They do it because they enjoy it. Most of them don't get paid for it. Many technical people don't enjoy writing documentation at all, and _very_ few enjoy writing documentation at the complete newbie level. If they don't enjoy it, they aren't going to do it for fun. If someone who _did_ enjoy it were to volunteer to help, well, that would be great. Further, you are working on a Windows platform. Microsoft has, at almost every turn, expressed its deep-seated hostility for Open Source software of all kinds, and even the very idea of OS software. Also, many developers, esp. those doing OS software which has a very UNIX-based ancestry, don't _like_ working on Windows, as they don't think it's a good platform either to use or develop on. So, naturally enough you won't find all that many Open Source developers who are very interested in expending a lot of effort to keep people who use Windows happy. They don't want to _encourage_ people to use an environment that is so hostile to the things they like to do, and they don't like using Windows themselves. So, I doubt you'll see a big effort expended on the part of OS developers to make the Windows-specific parts of their software simpler. There are, obviously, some well-known exceptions like the StarOffice/OpenOffice folks, Emacs, Apache, etc. who do spend a lot of effort trying to get Windows versions easier to use and install. If you wanted to buy a support license for MySQL, I'm sure they'd help you get it installed properly. If you want to use the free version and you want to use it on Windows, then, for better or for worse, you're going to have to get used to life on a second-tier platform :(. -- --- Paul D.

Floats
Hi List, I'm a little bit confused. I do the following: Create a table with 1 int and two floats. mysql create table testfloat(z int, ll float, ul float); Query OK, 0 rows affected (0.00 sec) inserting one row into the table mysql insert into testfloat values(1,-0.1,0.1); Query OK, 1 row affected (0.00 sec) check if values where inside mysql select * from testfloat; +--+--+--+ | z| ll | ul | +--+--+--+ |1 | -0.1 | 0.1 | +--+--+--+ 1 row in set (0.01 sec) and now I wants to take a look on special rows.. mysql select * from testfloat where ul=0.1; Empty set (0.00 sec) I didn't understand why I didn't get what I expect.

I have found that sometimes (esp. with older versions of MySQL which is not the case for you) that the only way to either repair or permanently repair a table is to dump/drop/reload the table and data. I had some instances a number of years back where the table would repair and be okay with isamchk but would, at a random time, be corrupted again.

Re: COUNT elements in a LIMIT query
On Friday 07 September 2001 15:37, Torgil Zechel wrote: Is it possible to get the total number of records when doing a select with LIMIT? No. As least, not in MySQL, unless I am missing something. For example, if I do: SELECT * FROM tbl LIMIT 0,10 I would like to get the total number of records in tbl along with the 10 first ones.. I need this to display showing 0 - 10 of 354, and my query is much more complex so I dont wan't to make two queries: SELECT COUNT(*) FROM tbl SELECT * FROM tbl LIMIT 0,10 COUNT is an aggregate function which works on the result set returned. You can therefore select a number of rows to be displayed and count these, or select all rows in the table and count these, but not both at once. (You can't have both your cake and eat it ;-) If UNION was supported, you could do something like SELECT field1, field2, ... fieldx LIMIT 0,10 FROM tbl UNION SELECT count(*), '', ... ''- provide x - 1 blank fields of the same datatype as 'fieldn' in the first SELECT which would provide you with the first 10 results as well as the total number of rows. This is however a pretty messy way of doing things and I would stick with two SELECT statements. BTW a simple COUNT(*) without a WHERE clause is optimized in MySQL.

Re: command line open source ARRRGGGGGG!!!!!!
I wanted to put in my 2 cents. Access is not an RDBMS.. It is a single user - small user, and frequent fix type system. I have never worked on a real database system that does not have a command line interface. It seems fearsome at first, but it's actually easy. SQL Server do doubt has very nice GUI tools, but having used that DB a bit, [as a user] I am not very impressed. I know these are pathetic questions to most of you so please have patience with a Windows user... what is shell? what is the ./? is mysql_installation_directory supposed to be replaced with my installation dir? On of the afore mentioned e-mails already answered most of this, but IU wanted to add some significance about the './' and why you need it and you DON'T need '.\' on a dos/windows systems. Any file in a unix environment can be marked executable. That does not mean it will run but any file can. Unix/Posix shells [you could related cmd.exe, or command.com to a shell] rely on the PATH variable to tell them where to run programs from. No Unix has './' [or the local directory] in the path, because it would present a small security risk when running programs, especially for the root user. Hence, if you want to run a program from a specific location that is _not_ in the PATH, you need to type in the relative, or the full path to the program. In this case, change to the directory where you find the program, and type: './progname' I realize that I'm going to be in the minority here but I have to say it. Open source would go much farther if they had self explanatory GUIs and had basic pre-setup apps that were ready for the average user to use. I program in Java and I feel the same about the JDK Sun produces. I use JCreator because it has an easy to follow GUI interface. Most open source apps I have attempted to use have some of the worse documentation around. The writers assume so much about the users. OK - call me inept, stupid, or whatever but I had to say it. I don't know what you've been using, but I have used a TON of open source, and most of it has good documentation. Partly because most opensource programmers think that you might want to understand the underlying process that the computer is going through in order to complete your requests, run the program, etc. Windows silently teaches you something else - using the pretty eye candy. You are gently brought in and taught one way of thinking and relating to your computer. But if you could step back and look at the skills necessary to run a GUI vs. use a command prompt , one is not actually more complicated than the other. [And you lose a lot of flexibility with a GUI]. Save one problem, people tend towards visual things, it's natural, and so they seem to fear CLI more than GUI. Oh, and on a more personal note, most people who have huge issues with open-source apps don't completly RTFM. They are impatient, frustrated and want all this stuff to work in 30 seconds otherwords is MUST be crap. However, 15 minutes of patient reading will often alleviate those issues. =P. Hope you get this figured out to your comfort. MySQL may take a little bit of extra effort to administrate, [esp. at first] but it is vastly superior to Access, and MUCH MUCH cheaper than SQL Server 7, or whatever. Also, it boasts one HUGE advantage over SQL server: You are not tied to a single proprietary platform =). - 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?

Mysql Fulltextsearch
Hello, Actually I am programming an web directory (like yahoo). But my sql queries need ernormous cpu resources. So it is quiet slow. I can't use indexing because my serach works with LIKE '%$serchstring%'. (apparently then it dosen't help). Now I was wondering if it would get faster by using FULLTEXTSEARCH on my tables. As it is quiet some work, I first want to ask you guys if this is really going to make my queries faster (much faster ?) Or perhaps you know any better solution ?

Let's approach stored procedures
I think this is a little OT here, so after reading please indicate me where to talk about this subject. I'm a skilled programmer in C, C++ and others progr. lang. I have also a solid background in SQL and some RDMS (DB2, Oracle, SQLServer, and of course, Mysql). I'm going to attend a long period of holidays (finally) so, I thought: why don't try to implement stored procedures in mysql ? Now, on with the questions: I think that MySQL programmers had yet thinked on some way to implement sp, and I'd wish that someone say me: - No, dude it's impossible/too hard - No, dude, we are in the way to finish that by ourselves - No, dude, we never insert big patches in our official distribution branch, that does not belong to us Or, better, something more optimistic... I don't want to loose my time, in something that you know is impossible or too hard to get. Another question: At a first glance, I think Oracle PL/SQL is the best (afaik) programming language for sp, but, in the case we implement that language, should we go against some Oracle copytight infringment ?

Re: Optimization question and possible bug
Stefan Pinkert wrote: Examine that query with explain select... show that the indexes are not used. The keyfields are unsigned tiny int where every bit has a different meaning. Any clue how i can rewrite this query in a way where the indexes are used? If MySQL thinks it will be faster to scan, it will. Make sure you analyze the tables with [my]isamchk -a. If that does not help, please send the output from SHOW INDEX FROM table and the EXPLAIN. In the database i have a merge-table that merges 10 myisam tables. Sometimes the loadaverage of the system raise above 50 and the long-query-log is filled with some query accessing the merge table. This happens 2-3 times a day. Only a minute later everthing is okay again without doing anything. I can't believe that it is a performance problem because there is a summary of only 10,000 entries in the merge table and 50,000 entries in other tables. Does anybody experienced this strange problem, too? Is the long query different than the other queries? Have you done an expain on it? The last thing i found is a possible bug in merge-table implementation of 2.23.41. After an update from 2.23.37 to 2.23.41 i got only the first row of the result set again and again.

Microsoft has, at almost every turn, expressed its deep-seated hostility for Open Source software of all kinds, and even the very idea of OS software. Also, many developers, esp. those doing OS software which has a very UNIX-based ancestry, don't _like_ working on Windows, as they don't think it's a good platform either to use or develop on. So, naturally enough you won't find all that many Open Source developers who are very interested in expending a lot of effort to keep people who use Windows happy. They don't want to _encourage_ people to use an environment that is so hostile to the things they like to do, and they don't like using Windows themselves. So, I doubt you'll see a big effort expended on the part of OS developers to make the Windows-specific parts of their software simpler. There are, obviously, some well-known exceptions like the StarOffice/OpenOffice folks, Emacs, Apache, etc. who do spend a lot of effort trying to get Windows versions easier to use and install.

Re: Query question.
Not quite. We're not looking for a left join or natural left join. I'm not sure MySQL or any database can even do this, it may have to be done (rather unattractively) on the API side. The data in the two tables aren't tied by ID, and shouldn't mix w/ each other at all. To do this, all we've been able to come up with is to use the API (PHP in our case) to make 2 queries, copy them into the same array, and sort the array by timestamp. However the API's array sort isn't the quickest thing ever coded, and the SQL level is where we'd like to do the sorting. To clarify, I'll give an example of what we are trying to do: daily_notes: note_iduser_numtimestampnote 111Hello 212Goodbye 3231 Blah project_notes: note_iduser_numtimestampnote 121Working hard 215Watching others work hard We'd like a query that would return daily_notes #1 and #2 and project_notes #2. However, like I said earlier, I'm not sure SQL can do this. This list is kind of a last resort before defaulting on letting the API sort it out after the 2 queries. Ken wrote: Sounds like a left join, maybe even a natural join, which I haven't tried yet. select message from project left join daily on project.uid = daily.uid order by timestamp Check manual for syntax. Or am I missing something? - Ken [EMAIL PROTECTED] At 05:47 PM 9/6/01 -0700, Michael Garvin wrote: Ok, we just can't seem to find a solution for this problem.

No, they do not differ from the rest. The only thing is that they need longer time to process (between 1 and 4 seconds, normally the SAME query is processed in a few miliseconds). The only correlation i found is that all queries in that log query the merge table. How does mysql handle locks on merge-tables?

Re: Let's approach stored procedures
Let me clarify. I'm in great favor of stored procedures in MySQL. It is my HO that all interaction with the database should take place within stored procedures. But the ANSI standard is sufficient for most interaction with the database. My call to arms was to resist the urge that Oracle could not, implementing a full-blown language within the context of SPs. (Oracle used Java, rumor has it that MS will implement C#, Java's moronic cousin, in a future release) Again, IMHO, take it for what it's worth.

Re: Let's approach stored procedures

SPs are also part of the ANSI spec so to be compliant, MySQL will have to have them. XML is not part of the ANSI-SQL spec. The other thing about all of this is that MySQL is feature rich so most people might not have a use for stored procedures. Unlike, say, Informix which has not build in MIN or MAX function. Again, if having stored procedures built in does not slow down queries that do not use stored procedures, I do not see what the harm is. --Bill - 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: Let's approach stored procedures
SQL. Stored procedures are loosely analogous to shell scripts. No additional language constructs, outside of what is defined in the ANSI-SQL standard are necessary for them. IMHO, C would be a bad thing. My $.02 worth, (which is worth less, each time I post) Cal * * Cal Evans * Senior Internet Dreamer * http://www.calevans.com * - Original Message - From: William R.

IMHO, Cal * * Cal Evans * Senior Internet Dreamer * http://www.calevans.com * Since the current version of MySQL is open source you could write stored procedures in the same language used in (until recently) DB2, i.e., C. I don't think that would be useful for those of us who are C challanged... I think the real question is, can it be done w/o impacting performance. Related question, what language or psuedo language would be used to code them. - Original Message - From: Ed Carp [EMAIL PROTECTED] To: [EMAIL PROTECTED]; [EMAIL PROTECTED] Sent: Friday, September 07, 2001 10:44 Subject: Re: Let's approach stored procedures Claudio Cicali ([EMAIL PROTECTED]) writes: At a first glance, I think Oracle PL/SQL is the best (afaik) programming language for sp, but, in the case we implement that language, should we go against some Oracle copytight infringment ?
