Re: New to MySQL on Linux
On Friday 11 February 2005 09:15, Terry Riley said something like: Having inherited an elderly PIII/500MHz box with an 8Gb SCSI disk, that had an apparently unusable XP SP2 OS on it, I decided to wipe the disk and install my first Linux instead, using an ancient RedHat 7.3 distribution. First suggestion: get something recent: Suse 9.2, Mandrake 10.1, Fedora Core 3, the latest Debian. A distro that old will have major security (and probably usability issues). Now the question: If I'm only using this as a database (no development) on RH7.3, which is the preferred download? I am confused by the plethora of options available for Linux. Just need something that is relatively simple to install (either 4.1.9 or 5.0.x). I would doubt the current MySQL RPM's would support something as old as RH 7.3. If you install something recent, there will be recent versions of MySQL (Mandrake even has 5.0 in the contrib section, I would assume Fedora would too. You will have to intstall the server portion, and probably the client portion. You then can use the MySQL GUI tools to admin the box from a Windows machine. Using something like Mandrake or Fedora, their installer tools will resolve all the dependencies for you. Hope that gets you started a little.

A UUID is designed as a number that is globally unique in space and time. Two calls to UUID() are expected to generate two different values, even if these calls are performed on two separate computers that are not connected to each other. This was added in MySQL 4.1.2.

Re: MySQL Secure Connection(e.g. SSL) Question
Something else to check out is Stunnel. It creates SSL tunnels between hosts without requiring logins (basically port redirection). Also, MySQL has built in SSL now, so you might want to look at that. j- k- On Wednesday 25 August 2004 08:10 am, [EMAIL PROTECTED] said something like: Something else I have done in the past was to use Cygwin to create an SSH session with the remote computer and use the remote computer's MySQL client/tools.

I also fiddled around with Cygwin long enough and hard enough (translate: I spent lots of time reading groups and docs and experimenting) to enable me to create local X windows so that I could run a full GUI shell (GNOME or KDE, I can't remember) remotely.

If I have maps of each state, pictures of each state's capital, etc., is there some BLOB feature that I would find really useful? All conventional wisdom I've ever come across for this type of application is that there's no advantage to keeping the image in the db itself. Just keep them as files on the server, store a filename /or location in the db if necessary, and use your middleware to display the images. Its faster, easier to maintain, and easier to backup. IMO, storing images in the db just bloats the file and complicates all the backup issues. -- greg willits -- Joshua J.

Re: triggers (or too-many-crappy-questions)
I found that the Postgres mailing list was full of very polite, super helpful people. I found that the MySQL list was full of relatively cranky people with little patience. Over that last year, I've I think I've discovered why. The average quality of the questions posted on the MySQL list are quite low (compared to the Postgres lists), and I think many of the people who are in a position to respond are fed up. That's part of the price of fame. You get more people who know of MySQL as a buzzword, so think Oh, I'll try that. In addition, there are a lot of open source programs out there that use MySQL as their back end, thus, many more people are trying to install MySQL. In the end, you get the people that don't and/or refuse to read documentation, and just post to the list. Sir, How I use MySQL? Why I want use it? Where I download from? Kindest regard. Not to disparage our foreign members, but it does seem that often those for whom English is not their mother tongue do not want to read through pages of English documentation. There are other languages for the docs I believe, but those don't always get found. Maybe a new MySQL list is needed - one called Dumb Questions, and when someone posts one to any other list, someone can quickly respond, Please repost this on the MySQL Dumb Questions list, as that's where it belongs. What is needed is moderation. I would happily volunteer to serve as moderator on this list (check back later to see if I've changed my mind :), as it is not terribly high traffic (and would be even lower if we eliminated all the newbie posts). When a post came across the list that is answered in the archives or the docs, a message could be bounced back saying so. It would probably cut list traffic by half. j- k- -- Joshua J.

Re: SELECT duplicate rows
Well, doing on all tables at once woule probably bring the server to its knees due to the cartesian product producing a VERY large temporary table. You can do it on two tables at once like this (if my memory serves): SELECT * from mytable as t1, mytable as t2 WHERE t1.column1 = t2.column1 AND t1.column2 = t2.column2 AND t1.column3 = t2.column3 AND t1.id t2.id Of course, you can extend that to as many tables as you want, but the syntax and performance complications quickly arise. I would recommend comparing all your tables to one another, two at a time. A quick perl or C script should accomplish this quickly. For 10 tables, that is only 45 queries. Not bad. j- k- On Wednesday 21 April 2004 12:56 am, John Mistler said something like: Thanks for the response, Joshua. I am so very new to MySQL, that I am afraid I require more guidance.

Re: disabling backslash as an escape character in strings
Are you using a high level library such as Perl::DBI? If so, you should run
all your strings the quote method. That will quote it properly for each
database you connect to. If you are connecting to all the databases yourself
using custom code, I would recommend you find some database neutral libraries
and go from there.
j- k-
On Thursday 08 April 2004 01:37 pm, Christos Karras said something like:
Is there a way to disable the use of the backslash as an escape
character in strings? I need to use an application that's designed to
work on any database server supporting ANSI SQL. When it generates SQL
insert/update queries, it doesn't escape backslashes in strings, because
the ANSI SQL standard doesn't require backslashes to be escaped.
So to insert the value \, the application generates the following query:
INSERT INTO (test) VALUES('\');
Which causes an error in MySQL because it thinks the \ is an escape
character and the string is not closed.
If I modify the application to escape backslashes by replacing \ by \\,
it works with MySQL, but with other databases that don't interpret the
backslash as an escape character, it inserts two backslashes instead of
one.
What could I do to tell MySQL it should interpret strings in the
standard way?
I tried starting mysqld in ANSI mode (mysqld-max-nt --ansi) but it
doesn't solve the problem.
I would also prefer a per-connection way to fix this, is there an option
I can set when connecting that won't affect other connections? I also
have other applications using the same MySQL server, some of which are
designed specifically for MySQL, so they may escape backslashes in the
MySQL way and switching the whole server to ANSI mode would break them.
I'm using MySQL 3.23 but I'm willing to upgrade to the latest 4.0x if it
can solve this problem.

Re: Security
You've been perfectly clear. The MySQL permission system will not define this level of security. You must design you application so that it will only give access to the rows that pertain to the customer that is logged in. Create a MySQL user which can read and write to your database. Then create another table in your database which defines users and passwords (separate from the MySQL users). When a user logs in, you check their username and password against your user table, and then once they are logged in, you make sure the only rows they see or update are rows that pertain to them. I hope this makes things clear. On Wednesday 10 March 2004 05:39 pm, Mulugeta Maru wrote: Hi Mike, I am sorry for the confusion I might have caused. May be it would help to give a clear example.

Re: Security
Yes, you make sense. But when you go in to access your bank account, you are not directly accessing the database. The web application is opening the database and only returning rows in the table that pertain to you. The web application can read all the rows; your user name has *no* read or write permissions to the database: the web application connects via its own username, and selects your account information from the database. So, in other words, you need to keep a list of users separate from the list of MySQL users. The mysql database controls which username/passwords can connect to the database. Your user list would contain users which can log in to your system. j- k- On Wednesday 10 March 2004 01:47 pm, Maru, Mulugeta wrote: When I go online to access my bank account I only see transactions pertain to my account only.

Re: Information request
Currently, everything you listed can be done via queries to the server. Take a look at the MySQL manual for all the queries and their requisite responses.

And the testing burden of the same software against several database back-ends would be considerable. Just one comment. If you are using MySQL, there would be no testing burden...against several database backends. The protocol, commands, connection methods, etc, are identical. A client on Windows, Mac, or *nix can talk to a MySQL server on a Windows, Mac, or *nix server, and will never know the difference. All it knows it that it is connecting to port 3306 and it's talking to a MySQL server. There is no difference among operating systems. j- k- -- Joshua J.

Re: locking
You can use MySQL's built in locking, or you can do this:
Find a job that is waiting
Run an update like this:
UPDATE table SET status = 'processing'
WHERE jobid = found_job AND status = 'waiting'
If you get back a 1 from that query, it made one change, and you're good. If
you get back 0 (no rows updated) someone beat you to it.

FieldTypeNullKey Default Extra

jobidint(11) PRI (NULL) auto_increment
status enum('waiting','processing','done','failed') YES waiting
created timestamp(14) YES (NULL)

Right now, a single process checks this table occasionally.
If it finds rows in 'waiting' status, it grabs the info,
sets the row to 'processing', and does the computation.
Upon completion, the process stores the results elsewhere,
sets the row to 'done' (or failed, if it failed), looks for
more work to do, and sleeps a bit if there is no futher processing
to be done now.
For speed, I'd now like several processes to grab work from the table.
I am not sure how mysql handles locking.
While a process is seizing a row (changing row status from
'waiting' to 'processing'), how do I prevent another process
from grabbing the same row?
Thanks for any help or advice

That's true. I'm only using one table. It is called a self-join. You alias the tables in the FROM clause, and then can refer to them as two separate tables in your WHERE clause. See the part of the FROM clause where I say as? That's aliasing the table. A temporary renaming, if you will.

Also, my reference material also indicates I need to add a line to the httpd.conf to give mod_auth_mysql the parameters it needs to connect to MySQL: Auth_MySQL_Info hostname user password Is this right? Where in the httpd.conf should this be placed. Any help would be great! Thanks, James -- Joshua J.

Re: problem: Loosing .MYD Files
Daniel - This might be a long shot, but since I've actually run into this problem before, here goes: Check your partitions. I had a server on which this very thing happened, and it turned out there were overlapping partitions. This was all fine and dandy until data was written to those overlapping areas, and created BIG problems when fsck was run. It sounds like your server might have gone down hard without a proper shut down, and then run fsck upon startup. Check your boot logs. It is also possible that there was severe corruption on the filesystem as a result of the system going down hard, and fsck did a best guess fix, which blew away your data. I may be totally off base, but your symptoms at least match what mine were. Hope that helps. j- k- On Wednesday 26 February 2003 00:50, Daniel Geske wrote: No, I didn't do anything at all.

The 10GB pretty sure weren't the 3 missing tables - the entire database never gets bigger than 1MB. To get back running for now, is it OK to 'touch tablen.MYD' to recreate the missing files.

Re: resetting mysql server gently
I agree completely with Egor! You should not be killing your processes to solve load problems. If there is a load problem 1) You need to write your applications better, 2) you need to have a better database structure, 3) you need to analyze where indexes would help you, or 4) you need a more powerful machine. I know Apache has directives in the config file to tell it the maximum number of daemons to run. As in real life, so it is with computers: killing never solves the real problem, it just make it go away for a while. So, tune your app, tune Apache, tune MySQL, or get a bigger machine. But DO NOT implement your kill when load is high solution. BTW, enough temporary glitches and you won't have users any more.

It's not illogical at all. You often want (sometimes need) that field to make sure a record has not changed when you go back to update the row. MS Access (and others) uses this so as not to overwrite changes made since the record was retrieved. You can't always rely on the client to set field=NOW(), and it makes for that much less coding. mysql, query j- k- On Friday 05 April 2002 07:53, Hihn Jason wrote: Yes I did, but it is very long, and it was very long ago. Could someone please explain to me why this was done? It seems more confusing to do this than to not do this. Why when you can just say SET field=NOW() in the update statement would anyone build this auto update of timestamps in? (the kicker is you HAVE to do it for all timestamps in a schema past the first) Additionally, what if I wanted the time stamp format (without formatting (spaces, colons, and dashes)) (which I do) A very illogical feature I must say...

Re: MyODBC for Core Business, followup...
To all: This is in response to a request for more information. I thought others may find it useful. Thanks so much for your reply. It's good news to hear that someone is relying on MyODBC for an important purpose, much of the usage I've seen seemed rather small. Like I said, we have had not problems with it, other than the problems that Access is causing because of its non-standard implementation of ODBC. I will make note of the fact, however, that we *did* have some issues with the driver, but those were fixed, and those bugs are now no longer a problem. Again, I think when it came right down to it, it was Access issues, and not really MyODBC issues. If you don't mind, I'd like to ask just a few more questions... Not at all. I'll do my best. - Can you describe what your application does a bit? I'm also interested in why you chose the Access/MyODBC route. My reasoning is a desire to PHP on the Web side of things, and certainly the easse and cost of running a MySQL server... The application primarily provides for entry, editing, and procession (through various states) of student government legislation. It also keeps track of who is in what postion, when they were placed and removed, and why. We also plan to implement a module that prints agendas and minutes. We chose Access/ODBC for a few reasons. 1) We were rewriting an existing application, and while it *was* a total rewrite, and went from using a local Access database to using a MySQL server, we wanted to keep the interface and behavior as similar as possible. 2) We wanted more control over format of reports. As much as I hate to admit it, Access does have strong (and pretty easy) report design and generation. This especially comes in handy when printing out official documents. Also, I didn't want to design reports by hand, as I would have had to do in Perl (formating issues, etc). 3) When wanting to update fields on the fly, e.g. change the values available in another field based on a drop down box, it can be very cumbersome to convert that to the web. Either you have to use Javascript and pull a new page every time, or make it a multistep process. It is much easier, from a design viewpoint, to use the instant response of a local GUI. We will, however, have an online module pretty soon here to search and view existing legislation, which was why we moved it to a MySQL back-end in the first place. - Any details on the 'gotcha' issues with Access you mentioned you've been through is certainly appreciated. Some you may have heard, others you may not. 1) Make sure every table has a unique ID field (auto increment works just fine) and a TIMESTAMP field. Access will use those on updates to make sure nothing has changed since it pulled in the record for edit, and to make sure it's only affecting one record. 2) On your connect options (either the FLAGS in connect parameters, or in ODBC setup) make sure you select Don't optimize column width and Return matching rows. Using both of these would make for FLAGS=3 in your connect statement 3) On direct connections, for some reason, using rst.addnew, adding values, and rst.update, then repeating that will repeat the value of the first rst.addnew. I'm quite sure it's an access bug. I have an MDB file with a test case if you are interested. 4) If you don't use the Don't optimize option above, updates using recordssets may end up with truncated data if the new data is longer than the old data. 5) Inserts on direct connections (and an empty table) using recordsets (not a direct INSERT query) fail, and insert blank records. Again, I have a test case for that. - I'm assuming your Access application is all with linked ODBC tables... what type of load does it receive and how is performance (vs. a more typical SQL Server setup if you happen to know)? We use a hybrid linked/direct connection set up. Partially for Gotchas 3, 4 and 5 above. But also for speed. We use some pretty hairy joins in our program. Some as large as 4 or 5 tables. When Access processes that, it breaks it down into 3 or 4 queries (for computability, I'm sure) and sends those. This makes it very slow. In one case, when I pull in a history, it could take 2 or 3 seconds (literally). When I optimized the query, and sent it over the direct connection, it could pull in histories as fast as I could click the mouse. We also use the hybrid setup because reports can't use direct connections. This does, of course, make for a rather dicey situation, since we need to do inserts and updates (sometimes with recordsets) on attached tables. Which means those tables need to be connected with the proper username/permissions. Which means we have the slightly ugly hack of attaching/unattaching the tables everytime someone logs in or out. It's not pretty, but it works. Our next time around for this application is going to be in VB (using

Re: Problem with MySQL and SMP?
We are having the same problem. Mandrake 8.1, kernel 2.4.17, MySQL 3.23.47. Dual PIII-500, 512MB of RAM, Mylex DAC960 RAID 5. After being up for a few days, the system completely froze.

What kind of crashes with GCC 2.96?
On the MySQL download page, there is a warning for GCC 2.96/x86/Linux that reads thus: Several of our users have reported random crashes and table corruption with MySQL binaries compiled with gcc 2.96 on the x86 Linux platform. I was wondering what kind of crashes users had experienced. Crashes of the database server, or crashes of the entire system?

But, I just installed a GCC 2.96 compiled binary** on a new Mandrake install, and today my server stopped responding after being up for a few days: couldn't ssh in, no console/keyboard/ctrl-alt-del. Nothing. Is this the kind of crash we are talking about, or should I look somewhere else? ** As to compiling with GCC 2.96, I don't have a choice. For MySQL to work with one of our Access applications I have to comment out one line of code (so SELECT...WHERE id = NULL behavior is the same as LAST_INSERT_ID() behavior).
