RE: Getting the unique auto-increment primary key after an insert
As stated only few days ago on this list, the LAST_INSERT_ID() is relevant per connection, i.e. it returns the correct last inserted id of the current connection, disregarding other possible inserts done through other parallel connections. So each connection has its own counter for this.

Can you get the results of an UPDATE command?
I've looked around and believe this to not be possible, but am checking just to be sure. Basically I want to run the command UPDATE MyTable SET SomeRecord = NewValue WHERE SomeRecord = OldValue But, I need to know which rows were modified, not simply how many. So far this is the best that I have come up with LOCK TABLES MyTable WRITE SELECT * FROM MyTable WHERE SomeRecord = OldValue UPDATE MyTable SET SomeRecord = NewValue WHERE SomeRecord = OldValue UNLOCK TABLES My question is.. isn't there a better way. One that doesn't require 4 queries to do such a simple thing? Or one that can be safely done in a multi user environment without locking the table? The queries run very quickly, and I don't actually process the SELECT results until after the table is unlocked... but it's kinda nagging at me that there must be a **better** solution than this. -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
Re: Can you get the results of an UPDATE command?
Hi Jason, If I understand correctly you need the SELECT statement first to detemine which records to update. However perhaps on the SELECT statement you could speed up things by showing only the required columns and not all. While this doesnt make a big difference for small tables, it can make one on big tables ;-). I know it is not what you were originally asking for, but in this way you could increase the availability of the server.

If You install Mysql from .dmg file it doesn't install mysql databases (grant tables, etc.) I think You have a permission problem so open a terminal and type su this command allows You to be root then chown -R mysql.mysql data(data owner must be mysql) chmod -R 577 data (allows everyone to write/read/list data) Then: ./scripts/mysql_install_db --force check again data I hope this solve your problem.

RE: mysqld question
Not a silly question... we all had to start somewhere... you can do it during the create table ( primary key ) http://www.mysql.com/doc/en/CREATE_TABLE.html or after http://www.mysql.com/doc/en/CREATE_INDEX.html what indexes do... lets say you do ALOT of queries on column user_id in the table user... select * from user where user_id = x or you sort,join,match on user_id alot. Then indexes will use a little more memory and it will make those queries a little (sometimes ALOT) faster. However, if you are inserting new rows ALOT vs selects... then indexes might actually slow you down a little because the database has to write to the table and then write to the index on each insert... So you dont want to add indexes on EVERY column... just the ones that you select or sory on most of the time.

mysqldump 8.22 and inifinite double values: Bug?
Hi All, I use MySQL 3.23.53 and mysqldump 8.22 and there is a behaviour in mysqldump I consider a bug. Anyone agrees? % mysql test mysql create table doubletest (d double not null); mysql insert into doubletest values(inf); mysql insert into doubletest values(-inf); mysql exit % mysqldump test doubletest d1.sql % mysql test mysql drop table doubletest mysql source d1.sql ERROR 1048: Column 'd' cannot be null ERROR 1054: Unknown column 'inf' in 'field list' mysql exit % cat felix.sql CREATE TABLE doubletest ( d double NOT NULL default '0' ) TYPE=MyISAM; INSERT INTO doubletest VALUES (NULL); INSERT INTO doubletest VALUES (-inf); The problem seems to be as follows: Apparently, mysqldump checks the value of the fields using isalpha. If isalpha returns true, the value is mapped to NULL (which is problematic if the column is defined NOT NULL). In the instance of -inf, isalpha returns false so mysqldump believes -inf to be a really numeric value and will dump the value unquoted. Questions: Is there a good workaround? I have found no option of mysqldump to force quoting on values of all colunm types. What possible values can be stored in a column of type double that are not merely numeric?

[MYSQL] Question about 'SHOW PROCESSLIST' output columns
Hello All, I'm having an intermittent problem with a MySQL server that I have running on a Windows 2000 Advance server systems. This issue occurs every few days depending on the load of the system. Here are the details. MySQL version 3.23.42-nt (I know I need to upgrade. Soon). Machine: Windows 2000 Advanced Server 2G memory 36G disk space. I have a Web page that allows my operators to monitor various process tasks on this server. Sometimes they receive an error that PHP cannot connect to MySQL. If this happens during the day they call me. I log into the server and bring up the WinMySQLadmin 3.1 client and click on the 'Process' tab. There are a few (maybe 250 attached processes). I know there are many machines connecting to this database to feed updates from enterprise applications. So I bumped up the 'max_connections' limit to 1000. This just seems to delay the limit and the phone call. My question is in looking at the output form the 'Process' tab I see the columns 'Command' and 'Time'. In all of the rows for 'Command' the value is 90% 'Sleep'. This would tell me I have some processes out there that are not dis-connecting (right?). In the 'Time' column is see numbers ranging from 150 to 1000+. I'm guessing this is the time the connection is idle (correct?). What I would like to do is define my parameters so that these dead processes will be disconnected by MySQL after a shorter time but not sure which variable to change. Advice? Paul
Anyone had a chance to try an Opteron yet?
I'm surprised there is not more interest in this; is it that not many work with large-ish (10+ gig) databases that need high-end performance? A 64-bit CPU won't have the 4-gig memory limit that a 32-bit processor will; even worse, Linux is apparently limited to about a 2-gig process. SuSe Enterprise Linux supports 512-gigabyte processes with 16 processors. Imagine 10 gigabyte database all in memory. Even better, larger file sizes - no more 2-gig files. Max file size is 9-Exabytes ( 9 followed by 18 0's ). All the posts I see about people trying to get around the 2 gig file limit should be really excitied. I guess I'm just surprised by lack of interest. I've been bugging our CTO once a week about this, and hopefully should have a server on my desk by mid summer to late fall. If you're interested, SuSe has a good PDF on AMD64 and SuSe Enterprise Linux 1.0: http://www.suse.com/en/business/products/server/sles/misc/sles8_amd64.pdf Anyone have some practical experience with the software and hardware?

Re: Anyone had a chance to try an Opteron yet?
Excellent point. How does MySQL run on Tru64? Any familiarity with it on Intel32? But there are some big drawbacks to these platforms: - they only run apps that have been specifically ported and compiled for them. The Opteron runs the same 32-bit code that an Athalon or Pentium class computer will run. Ports aren't always available, and they can lag behind w/regards to the versions available. Ports can be buggier as well. - Those systems are expensive. Opteron hardware is relatively cheap ($1000 for a motherboard and two processors), and much of the hardware is generic (no super-expensive RAM from Sun). Because the hardware is generic, you have more options at a lower price point. I'm not sure how a 32-bit IDE RAID driver would do in a 64-bit version of Linux. If a 64-bit driver is needed, then there might be some issues. - This is new hardware. People who work with computers like new toys. They like to set them up, test them, and then tell everyone what they thought. Anyway, hopefully someone will have some insight.

Not necessarily. People that need relatively affordable 64 bit systems may be waiting for the Opteron to stabilize.

Also, given that HP has basically dropped Alpha, I don't think a lot of people are likely to be implementing that platform.

Re: Anyone had a chance to try an Opteron yet?
64 bit servers have different performance characteristics and tend to be used for different things. than PC systems. They are generally backplanes to which are attached some number of processors and some amount of memory, and a lot of IO. They aren't used as much for processor speed (you could get a bunch of PCs to do that) as they are for doing a lot of IO. Even a small server like the old Sun e450's (4 processors) had something like 6 or 8 PCI busses on them. Larger systems could be configured with a large number of IO cards for those computers that just need a few gigabit per second of network IO and a ton of disk space (multiple disk controllers, or FC controllers all going full speed). You would use the memory to store temp information as a query would run and you rely on the systems fast access to the disks to scan through the tables. You would generally attach anywhere from a few hundred gigs of disk (spread out over many smaller disks) up to many terabytes (it's been a while since I've done large system admin work, so I have no idea what the largest systems are doing, but imagine 72 cabinets full of 72 GB or larger disks). This way instead of getting speed from caching the data you get speed by reading the data off the disks quickly. 64 bit workstations had an advantage over PC systems most of the time in that the memory bus was not the bottleneck it can be on the PC avoiding delays due to cache misses, which made them great for visualization workstations where the system had to scan through a lot of memory quickly to generate an image or process scientific data. There's a lot of other things going back to the fact that Digital, HP Sun and IBM have always had a head start on superscalar and multi-core CPU designs, so comparing Mz was never even close between two processors. On the other hand many people never saw that advantage because they would compile with gcc which was never the best choice for pure speed on a given processor. If you need a 64 bit processor for memory and file size concerns and can sacrifice some of the processing speed (which often goes away because of the faster IO) there's always been a good used market, in particular for Sun equipment. I've seen some dirt cheap prices on fully loaded Sun E450 systems which are very nice for their size. I think they hold 20 disks internally and there's PCI slots for a lot more if you need large files. On the other hand I think need 64 bit and affordable are rare situations. -- Michael Conlen Mike Wexler wrote: Not necessarily.

MySqL running very slow on HP 900-UX 11 - 32 bit
Hi all, I am trying to create tables and insert data into MySql Version 3.23.53-Max database on HP 900-UX 11 - 32 bit server. For some reason a job , which is suppose to take 45 mins, is not completing even after 2 days. It means all jobs against mysql are running very slow on HP 900-UX 11 - 32 bit server. I did check file system, system load and other system related things, they are fine. I wonder anything to do with MySql installation of 32-bit v/s 64-bits. MySql is installed on /data drive and all mysql database files, log files and dump files are on same drive i.e I am having everything /data drive as we have only one external drive on this server If anyone of you think of anything on this, please let me know. Thanks, shanth
Replication Performance
Hello 1/ I have a search engine which crawls auction sites and returns information which is inserted into a mysql database. This activity represents on average about 3 inserts per second with a combined payload of 450 bytes per second added to the database. This updating occurs continuously throughout the day. Since this activity puts a burden on the machine on which it occurs (not only the mysqld inserts but also the scripts and http client activity), I am planning to dedicate one box to the crawling/inserting and replicate the data to one (or possibly more) other servers. These slave servers will handle all client requests (almost exclusively reads). The mysql documentation states: You should set up one server as the master, and direct all writes to it, and configure as many slaves as you have the money and rackspace for, distributing the reads among the master and the slaves. My questions are: Since the updating occurs throughout the day and the same amount of data has to be eventually inserted into the slaves I assume the updating will require the same amount of resources (disk, cpu usage) on the slaves as on the master - the same number of writes will occur on the slaves. So the the benefit of this configuration (in terms of performance) is that it is the extra processing required to do the crawling will be offloaded to the one master server, not the resources required for the mysql writes. I assume inserts done thru replication are not more efficient than regular inserts. What is the performance hit of replication and is there a way to limit the effect of the writes on the slave servers, thru configuration parameters, for example, or would it even make sense to take the slave offline at regular intervals while replication is taking place? 2/ Is there any documentation on handling and configuring large tables? Hope this is not too confusing...

Re: mysql 4.1 authentication problems
Funny. I was just readin about this on the www.mysql.com web site. Under the
documentation section about upgrading form 3.23 to 4.0. The exact URL is
http://www.mysql.com/doc/en/Upgrading-from-3.23.html
Ensure that you don't have any MySQL clients that use shared libraries (like the Perl
DBD-mysql mode). If you do, you should recompile them, because the data structures
used in `libmysqlclient.so' have changed. The same applies to other MySQL interfaces
as well, such as the Python MySQLdb module.
MySQL 4.0 will work even if you don't do the above, but you will not be able to use
the new security privileges that MySQL 4.0 and you may run into problems when
upgrading later to MySQL 4.1 or newer

I think you are definitely overgeneralizing here. I used DEC Alpha's back when they were in Alpha testing and I've also used several machines with the MIPs chip in them. Not all 64 bit machines are of the sort you describe. I've had several different 64 bit machines on my desktop. As far as mysql is concerned, there is definitely a market for cheap machines with 4GB of memory in one process. My DB server currently is an x86 system with 4GB of memory. I guarantee that having twice as much RAM and having it usable by the MySQL process would be a big win. And an opteron system with a 64 bit processor is roughly the same price as an Intel system configured similiarly. Where as similar machines from companies like Sun, HP or IBM are definitely much more pricey. I do understand if you want terabytes of disk and very wide I/O buses that costs more no matter what CPU you have. But its also true that given a particular requirement for CPU, I/O and memory, if an Intel system with relatively stock parts can handle it, it will be cheaper due to the economics of scale and the amount of competition in that marketplace. You would use the memory to store temp information as a query would run and you rely on the systems fast access to the disks to scan through the tables.

Confused about MyISAM vs InnoDB tabel types
Can anyone either summarize for me a comparison between the MyISAM and InnoDB MySQL table type? I am getting ready to upgrade from MySQL 3.23.42 to 4.0.13 in the coming week and started reading the upgrade documents on the www.mysql.com site. Never had even thought about using another table type since my current database seems to work fine. But thought I would ask.
Searchable docs in french, german, russian etc
Hi MySQL doc team, I have was wondering if a change could be made so that when I browse the MySQL docs in some selected language there is a search window that searchs first the language I have currently selected. The search always returns the english documentation page even when the page exists in the language I am browsing! Browse in french, http://www.mysql.com/doc/fr/index.html then use the search and it returns english!

RE: AES 256-Bit Encryption and /etc/my.cnf
It would be really nice if ANY of these kinds of configuration options were settable via the /etc/my.cnf file. I use RPM's almost exclusively for their ease of maintenance, compatibility and stability and I certainly wouldn't want to go and have to re-compile anything just to change a value from 128 to 256.

Re: Replication Performance
On Tue, Jun 24, 2003 at 03:34:48PM -0500, Todd Burke wrote: Hello 1/ I have a search engine which crawls auction sites and returns information which is inserted into a mysql database. This activity represents on average about 3 inserts per second with a combined payload of 450 bytes per second added to the database. This updating occurs continuously throughout the day. Since this activity puts a burden on the machine on which it occurs (not only the mysqld inserts but also the scripts and http client activity), I am planning to dedicate one box to the crawling/inserting and replicate the data to one (or possibly more) other servers. These slave servers will handle all client requests (almost exclusively reads). [snip] My questions are: Since the updating occurs throughout the day and the same amount of data has to be eventually inserted into the slaves I assume the updating will require the same amount of resources (disk, cpu usage) on the slaves as on the master - the same number of writes will occur on the slaves. Yes. So the the benefit of this configuration (in terms of performance) is that it is the extra processing required to do the crawling will be offloaded to the one master server, not the resources required for the mysql writes. The real benefit is that clients reading the data don't block writes on the master AND you can have many, many, many more clients reading the data this way--more than a single machine could ever handle. I assume inserts done thru replication are not more efficient than regular inserts. Right. What is the performance hit of replication and is there a way to limit the effect of the writes on the slave servers, thru configuration parameters, for example, or would it even make sense to take the slave offline at regular intervals while replication is taking place? The performance hit of replication on the master is trivial. I've had 40 slaves (or was it 30?) replicating from a master with no side-effects. I can think of no reason to pause replication on the slave(s). 2/ Is there any documentation on handling and configuring large tables?

I was assuming (until now) that HEAP tables are (the only one type of) temporary tables. I tried CREATE TEMPORARY TABLE temp TYPE= InnoDB SELECT * FROM relations; or CREATE TEMPORARY TABLE temp TYPE= HEAP SELECT * FROM relations; and they are all created as in-memory tables no files are created. Can I use any table format (ISAM,MYISAM,BDB,InnoDB,HEAP) for temporary tables ?

Re: LAST_INSERT_ID() returns different values on different connections
At 16:02 +0300 6/17/03, Baris Akin wrote: Hello, I try to get last inserted autoincrement record ID on table with LAST_INSERT_ID() function (SELECT LAST_INSERT_ID() FROM TABLE). Every connection returns it's own last inserted ID not actual ID. Is this a bug? Also it returns more than one record (20 rows). It's supposed to return the last ID generated on that connection. (I'm not sure what you mean by actual ID, because I would expect the connection's last ID and actual ID to mean the same thing.) The reason you get back multiple records is because you're using SELECT LAST_INSERT_ID() FROM TABLE rather than SELECT LAST_INSERT_ID() What's happening with your query is that you're returning the ID once per row in your table. Drop the FROM TABLE in your query and you'll get just one row back.

Re: default value does not set using LOAD DATA INFILE ...
Thank you for your response to my first post on this list. I really appreciate your time to answer my question. I tried every thing I could think following the manual for LOAD DATA before I joined this list. I probably did not explain my problem clearly in my initial post. What I try to do is to import a csv data file into MySQL using LOAD DATA INFILE I would like to leave some fields blank in the csv file, and let MySQL to set default values to those fields in the database when loading the data. But every thing goes fine except the default values do not set. Although it was the first time for me to send the post on this list, I was sure that I did not follow other people's threads. I checked my original post again after read your response, and I did start with a new thread. However, I apologize if somehow I did make any mistake.

SELECT something FROM somewhere MINUS SELECT something_else FROM somewhere; Or this one could do the job but mysql doesnt seems to accept it either.. SELECT id FROM there WHERE id != ( SELECT id FROM this_one ); so Here's what I want to do... my Tables are : CREATE TABLE Place ( id INT UNSIGNED NOT NULL AUTO_INCREMENT, Name VARCHAR(60) NOT NULL, Desc TEXT, PRIMARY KEY (id) ); CREATE TABLE Place_link ( Place INT UNSIGNED NOT NULL REFERENCES Place(id), LinkTo INT UNSIGNED NOT NULL REFERENCES Place(id), PRIMARY KEY (Place, LinkTo) ); I got a table with different places (Amusement park, Store, etc... ) and the Place_linf table contains the id of a place (Place) and if from that place, you can go to another place, its in the LinkTo. example : You got the 1:Market, 2:Zoo, 3:Pool, 4:Arena, 5:Stadium From the market you can go to the zoo and the Arena, and from the pool, you can go to the zoo, and the market... so we have : Place - LinkTo 1 2 3 1 3 2 1 4 so my query is: I want Place(id,Name) from Place but not the market (id != '1') and not the place where the market has a link to (not 2, 4).

emalloc() error being thrown {LONG}
Good morning!
(My apologies for sending to both lists, I found emalloc() info on both
PHP and MySQL that might be applicable and could not make a good call as
to where this might be more appropriate)
We are attempting to return a rather large file from a set of queries to
MySQL via PHP. Each time the query completes we are freeing the result
(mysql_free_result) so that we do not get memory errors, but at about 20
MB (tested multiple times) we get ...
FATAL: emalloc(): Unable to allocate 2 bytes
Here is the code
?php
//connect to and select database
include(dbconnect.cali.php);
//include test data vs. real data
include(choose_data.cali.php);
// get list of originating RC
$qorg = SELECT DISTINCT(originating) AS original FROM .
$curtblRCscope . ;
if(!($dborg = mysql_query($qorg, $dbconnect))){
print(MySQL Reports: . mysql_error() . \n);
exit();
}
// create array so memory from query can be freed
$a = 0;
while ($org = mysql_fetch_object($dborg)){
$orig_array[$a] = $org-original;
$a++;
}
mysql_free_result($dborg);
$orig_count = count($org_array);
if ($curtblRC == tblRC){
$curpath = /var/lib/apache/htdocs/callscope/output/;
} else {
$curpath = /usr/feynman/lcs/;
}
if (!($npanxxfile =
fopen($curpath.npanxx.cali..date(Ymd)..txt,w+))){
print(Failed to open file!\n);
exit();
}
//file was opened
for($i = 0; $i $orig_count; $i++){ // start writing loop
//get npanxx list
$qnpanxx = SELECT DISTINCT c.originating as origin, c.terminating as
termination, a.npanxx as o_npanxx, b.npanxx as t_npanxx ;
$qnpanxx .= FROM .$curtblRC. a, .$curtblRC. b,
.$curtblRCscope. c ;
$qnpanxx .= WHERE a.RCname = ' . $orig_array[$i] . ' ;
$qnpanxx .= AND a.RCname = c.originating ;
$qnpanxx .= AND b.RCname = c.terminating ;
$qnpanxx .= ORDER BY c.originating, c.terminating, a.npanxx,
b.npanxx ;
//$qnpanxx .= LIMIT 5 ; // for test purposes jb
if(!($dbnpanxx = mysql_query($qnpanxx, $dbconnect))){
print(MySQL reports: . mysql_error() . \n);
exit();
}
if (mysql_num_rows($dbnpanxx) 0){ //start if
$npanxxcnt = 0;
while($urownpanxx =
mysql_fetch_object($dbnpanxx)){
//output originating npanxx
fputs($npanxxfile,
$urownpanxx-o_npanxx);
//output terminating npanxx
fputs($npanxxfile,
$urownpanxx-t_npanxx);
//output spaces in characters 13-66
for($spaces = 13; $spaces = 66;
$spaces++){
fputs($npanxxfile, );
}
//output N
fputs($npanxxfile, N);
//output spaces in characters 68-86
for($spaces = 68; $spaces = 86;
$spaces++){
fputs($npanxxfile, );
}
//output terminating newline
fputs($npanxxfile, \n);
$npanxxcnt++;
}// end while
mysql_free_result($dbnpanxx);
}// end if
}// end writing loop
fclose($npanxxfile);
?
Here are a couple of lines of the output file...(the spaces are
necessary). Each line is 87 bytes long including the newline character.
626677213532 N
626677213533 N
626677213534 N
626677213538 N
626677213542 N
I have STFW, RTFM taken a couple of SWAG's and still cannot come up with
a solution. Is the opened file held in memory and therefore as it gets
larger it approaches the memeory limit of the machine? Any insight would
help...a BIG THANKS IN ADVANCE!
