Re: Prevent execution of queries without a WHERE clause
Hi, You can check this feature out on section 2.9 on the mysql 5.0 certification guide (page 44). this feature has some side effects other than requesting a where with deletes and updates i.e. Quoting for whoever doesn't have the MySQL certification study guide 1.UPDATE and DELETE statments are allowed only if then include a WHERE clause that spedifically identifies which records to update or delete by means of a key,value or if they include a LIMIT clause. 2. Output from single-table SELECT statments is restricted to no more than 1,000 rows unless the statment include a LIMIT clause 3. Multiple-table SELECT statments are allowed only if MySQL will examine no more than 1,000,000 rows to process the query. The --i-am-a-dummy option is a synonym for --safe-updates. :) Gluck Darren On Tue, Sep 8, 2009 at 10:25 AM, Ian Simpson i...@it.myjobgroup.co.ukwrote: Thanks John, that's done the trick On Mon, 2009-09-07 at 18:24 +0100, John Daisley wrote: Add the option 'safe-updates' to the mysql section of your 'my.cnf' / 'my.ini' file and restart the mysqld service.

I now can't find any reference to it, other than a vague mention of using safe mode in the comments in the mysql docs; it doesn't explain if that is starting with --safe-mode, or using the mysqld_safe script. Both of these modes seem remarkably poorly documented, making me unwilling to experiment with them without advice, in case one of them disables networking or something similar.

Re: optimize my.cnf
Hi Christos, Performance optimization is very subjective, and if you are experiencing low performance it can be a million different things. The description you provided didn't mention any of your current my.cnf settings, nor did it mention what kind of tables your database contains, size of data, types of indexes, engines used by your tables etc. You mention you have a quad core machine running 8G ram how much of that ram is being used by MySQL and how much by other applications? how much of it is free? What kind of CPU usage are you experiencing, what is the size of your db, are you logging slow queries and checking for missing indexes? My.cnf is not a magic box which improves performance by setting a couple of variables and normally the performance improvements are minimal as compared to other things like: 1: faster disks 2: normalized and correctly designed db (not in your power I guess) 3: good code in your application (not in your power either) I'd suggest you read High Performance MySQL 2nd ed which will definitely be of help. Sorry for bombarding you with questions but performance tuning is not something you do by setting a couple of params on my.cnf!

[OT] HP DL760G2 vs Opteron for large DB on Linux
Hi all, I am looking to purchase hardware for a large database running MySQL or Oracle on Linux. Was thinking of the Opteron for its good scalability and memory bandwidth until my friend told me that the DL760 from HP that uses the F8 (from Intel Profusion) chipset allowing up to 8 CPUs and memeory up to 32GB. I have always though that the Xeons cannot go beyond 4 CPUs and 4GB but this changes the equation. Has anyone got experience with this server or similar ones?

MySQL database. It keeps bombing with a segfault during what I think is the
db connect. I recompiled everything with debug and ran mysql_debug in the
code and am getting the following:
[youngd@fett]:~/src/logit $ ./searchlog -d

It picks up the connection info from a config file. I have other utils that
use the same config file and parsing code which work ok. The host, db,
username and password are used by other scripts and programs. The only thing
this program does is runs a single select query against the db.
Any ideas what error 111 and/or 2003 is? Other thoughts?
The actual debug used in the code is:
mysql_debug(d:t:F:L:n:N:P:o:, /tmp/client.trace);

MySQL List
I've sent a couple of messages to the MySQL list today that didn't seem to
get through. Have there been any problems with the list and/or the manager
today? One of them was returned as being too large to be posted and it
really wasn't all that long. One of them never made it through and was never
returned. This one was originally returned as spam since it didn't contain
any words related to sql, mysql or query. Are the list filters or posting
rules available somewhere to read?
Here's the question I had earlier from the first message that was returned.

It doesn't generate a core dump by the way. If I run a strace on the same

The username/password/host/database all work fine from the mysql client as
well as from other programs that use similar shared code as the one that's
broken.

Re: Re: problem with load data local infile
Both files are world readable. How do you know this? Because FTP tells me they are. Also, when you say client machine, what do you mean? In particular, are the web server and the MySQL servers running on the same machine? Client machine is the machine running the webserver and MySQL client. The host machine runs the actual MySQL server. - 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: Queries entering Sleep state.
If say, that client closes the connection at some point in the future...that will clean up then? Or has the connection been severed? -Original Message- From: James Montebello [mailto:[EMAIL PROTECTED]] Sent: Tuesday, January 15, 2002 1:59 PM To: Greer, Darren (MED) Cc: '[EMAIL PROTECTED]' Subject: Re: Queries entering Sleep state. This is caused by a connection that's still held open by a client, or (more commonly) by a connection that wasn't closed gracefully by the client. One of the oddities of TCP is that one end of the connection won't know that the other end has dropped the connection until it tries to write something to the connection. Since MySQL doesn't write except in reply to a query, it's sitting there with one end of a dead connection patiently waiting for a new query to arrive. james montebello On Tue, 15 Jan 2002, Greer, Darren (MED) wrote: Hello again all.

General Query time question
Hello all. I have a database which is around 10million rows.

RE: General Query time question
You are correct, they are simple Y/N fields. I am not familiar with the process you mentioned, but will do some digging. If you have any information you could give me that doesn't require too much of your time, I would appreciate it. Thanks, Darren -Original Message- From: Bogdan Stancescu [mailto:[EMAIL PROTECTED]] Sent: Tuesday, January 08, 2002 10:37 AM To: Greer, Darren (MED) Cc: '[EMAIL PROTECTED]' Subject: Re: General Query time question I'm just guessing here, but I suppose most of the char(1) fields are y/n fields. If that's the case you should consider using a single BIGINT and flag those bits instead. That would considerably reduce the size of the table on one hand and I guess it should improve things speed-wise as well. Obviously, my whole theory stands on a supposition, so I might be wrong in suggesting this.

RE: General Query time question
If I move the status to another table, and then wanted to get a count of everyone who is of status 'A', how would that be any quicker? Would I join the tables? -Original Message- From: Carl Troein [mailto:[EMAIL PROTECTED]] Sent: Tuesday, January 08, 2002 11:34 AM To: [EMAIL PROTECTED] Subject: Re: General Query time question I didn't think/read far enough. One more attempt is due. Correction on the query: SELECT count(*) as count FR OM userdata WHERE status = 'A'; I didn't see that it was on that column you had an index, so forget I said 'of course'. Have you used EXPLAIN to figure out if the index is actually used in the query? If you haven't already, consider running an ANALYZE TABLE just so MySQL can get some idea of the distribution for the indexed columns. It might help the optimizer make a better decision if it's not already doing what's best. If the status column only has a few different values, an index will not be used because the overhead of using the index will be greater than the benefit. If this is the case, you'll be better off without the index, and you could consider one of the two options I rambled about in my previous mail. //C - sorry 'bout that. -- Carl Troein - Círdan / Istari-PixelMagic - UIN 16353280 [EMAIL PROTECTED] | http://pixelmagic.dyndns.org/~cirdan/ Amiga user since '89, and damned proud of it too. - 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?

mysqld daemon ended on first connection
Hi, My server just crashed yesterday nite. After I got it up and running again, I couldn't get connection to MySQL database. Mysqld processes are checked and verified running upon booting up. But it just went dead after I tried to get a connection thru mysqladmin!! It just says error connecting to server at localhost. /etc/hosts has been checked and the entry for localhost is found in it MySQL version is 3.22.32 and is currently running on Redhat 6.2. What could be the possible reason? Could it be permission problems? I have already carried out a repairing and reindexing of the database tables but to no avail! Please help... Thanks, Darren
Build problems.
apologies if this is documented somewhere, but i have found much of the material confusing. I am attempting to build mysql-3.23.39 on a sun Solaris 2.6 box, with the languages / utilities installed. 1. perl5.6.1 2. GNUmake 3. GNUm4 4. GNUtar 5. apache1.3.19 6. autoconf-2.13 7. automake-1.4 8. gawk-3.0.4 9. bison-1.28 through documentation i can see there are a number of ways to install the mysql 1. compile the source (currently i am using this), but i have hit problems that suggest i don't have the relevant C++ libraries for my gcc complier. a. Installing the libstdc++-2.8.1.1 should rectify this? compiling the source for this is a problem , producing unhelpful errors after a lengthy configure process. if somebody can provide docs on how to install these libraries successfully i would be keen to hear about, either as the precompiled binaries or the source code. b. mysql documentation recommends that In this case, you can remove the code in `configure' that tests for the C++ compiler and then run `./configure' with the `--without-server' option - can anybody throw light on what the without server option is about? 2. use binaries (not used yet).

AIX recommendations
This note is primarily meant to stuff something into the archives in case other people have problems compiling mysql under AIX. There are a number of changes that need to be made that aren't detailed in the documentation, (some alteration to those docs could save someone a lot of effort in the future). I don't know how universal this is so I will say that this works under AIX 4.2.1 for mysql 3.23.37 using gcc 2.95.3 To begin with, you may need to use the following config as opposed to the one given in the docs... CC=gcc -pipe -mcpu=power -Wa,-many \ CXX=gcc -pipe -mcpu=power -Wa,-many \ CXXFLAGS=-felide-constructors -fno-exceptions -fno-rtti \ ./configure --prefix=/usr/local/mysql --with-low-memory The key change here is the -mcpu, the docs specify power2, but that causes compiles on older equipment to toss out bad assembly code. Determine what your cpu is if you are experiencing errors that indicate that problem. Typically power2, power, or powerpc may need to be used, alternatively you might need to use 604 or 604e. I'm not positive but I would think using power would likely be safe most of the time, even on a power2 machine. If you don't know what your cpu is then do a uname -m, this will give you back a string that looks like 000514676700, with a format of xxyymmss where xx and ss are always 0's, yy is a unique system id and mm is the id of the CPU Planar. A chart of these values can be found at http://www.rs6000.ibm.com/doc_link/en_US/a_doc_lib/cmds/aixcmds5/uname.htm This will give you a machine type and a machine model you can use to determine what type of cpu you have. Next, after configuring, edit config.h and change the line that says #define HAVE_SNPRINTF 1 to #undef HAVE_SNPRINTF Do the same for include/my_config.h There is probably a better way to handle that that would address the issue for the entire source but I didn't take the time to find it nor did I stumble across it. And finally, in mysqld.cc you need to add a prototype for initgoups. #ifdef _AIX41 extern C int initgroups(const char *,int); #endif After doing this, I had a version of mysql that I could compile and install. Hopefully there aren't any bugs waiting for me as a result of these changes. I'm seeing test failures for tests rpl15 and rpl16 that I haven't dug into yet but everything else looks ok.

MySQL Failing in Runlevel 5 on SuSE Linux 7.1 Pro
Hi I've recently installed MySQL onto suse linux 7.1 pro using the YaST2 installation program. When my system restarts a mesage saying that mysql has failed in runlevel 5 appears, however the database does appear to be running as I can connect to it via the mysql client and view databases etc. I would be very grateful if anyone has advice that would enable me to track down the cause of the message and the problem (if there is a problem).
