INSERT query crashes MySQL
This morning our MySQL exited for no good reason!
mysql.err:
021020 17:25:53
021020 17:
021022 18:20:16 mysqld ended
mysql.log:

243748 Init DB mydb
243749 Connect [EMAIL PROTECTED] on
243749 Init DB mydb
243748 Quit
243749 Query INSERT INTO IDRefs
VALUES('5136110c98b89de5d389df0754182ff2','','',NOW(),'Not available','','')
When I logged into mysql manually, there was an error relating to the IDRefs
table, (can't remember exactly but it was something like Cannot get data of
table structure - I was in a rush to get things up and running!). I deleted
the contents of this table and used OPTIMIZE and it has worked OK since
then.
However, a similar crash occured on Sunday, but I didn't investigate it
fully. So, why is this INSERT query causing MySQL to crash? The table it
uses is the one that keeps track of users and their shopping bag (online web
ordering facility).
There was plenty of disk space on the server, Solaris 2.7, using mysql
3.23.51.
Thanks for any advice
John

Here you get it right. glibc is much more responsible for ip-hostname-mapping than the operating system kernel itself. Kernel implements the IP protocol with dotted-format addresses, and it expects user-mode libraries to do any necessary conversions. That is, when you do this: ping www.google.com the ping binary calls a couple of conversion functions in user-mode libraries so that it can pass a real IP address to the kernel/protocol interface.

RE: Remote Connectivity
Well, you could have the Canadian admin add your pakistan IP address/host to the mysql database in the hosts table, along with the proper user and db I'm sure. Then you can use any 3rd party mySQL client to connect and do whatever you want. Something I just did recently is to install phpMyAdmin (http://www.phpmyadmin.net/) on the remote (canadian) server and use the built in export feature. This feature is incredibly slick, it even automatically .zip or .tgz the file for you and pushes it to you! The compressed version is significantly smaller than the full version of the .sql file. Then you simply login to your local mysql database (whichever you choose) using the 'mysql' command line client and use the \. option to create the tables and all the data in one go from the unarchived .sql file you just created. It worked flawlessly for me. The other option is to have your ISP send (email/ftp) all the /var/lib/mysql/mydatabase files (archived I assume), put them in the same dir on your server, and restart mysqld. I have MySQL 3.23.36 on my web server somewhere in Canada, while I live in Pakistan. I want to connetc to my database out there and use a query to download all the data from that mysql db to my own mysql db.

RedHat8.0 and MySQL
Hi, dont know if this is old information, but: RedHat 8.0, MySQL 3.23.52. It works like a charm from the local machine, but when you try to connect by TCP, the active thread seg-faults. (strace on mysqld) The solution was to place the host I connect from in /etc/hosts. Voila, no more seg-faults.. I guess this is due to some oddity in RedHat 8.0, but I could not find this documentet anywhere. So now everybody knows..

Re: INSERT query crashes MySQL
Error 144 that the table is crashed and the last repair failed. You should run a check and optimize on this table if possible. Error 13 indicates that you do not have permission to access the file. If you are the System Administrator you may want to check the file permissions. Otherwise, you will want to get in touch with the System Administrator. Thanks Victor I had moved the tables to IDRefsOLD.* so I could look at them later if necessary, and copied them back - with my user login instead of the mysql:* user. That explains the error 13. What could cause the error 144? This particular table keeps getting corrupted, and I have no reason why.

Problem with select.
HI, I don't know is it bad or not but I face queries the work quite long time. the sql is : select * from log_answers_index limit 0,10 and it takes too much time for me to receive the result. I got indexes on most of the fields, i got primary key which is auto_increment int(11). When I did explain on the query I got this : type : ALL rows : 123010 all other cells are empty. When I do : select * from log_answers_index where log_entry_index between 1 and 10 i got type : range For me it is strange that the primary key is not used when there is LIMIT clause without WHERE one.

Another bit off-topic question
I'm planning on using Win2k Adv. server, IIS, MYSQL, PHP on a dual processor 2.4GHz processor with 1 or 2GB RAM, with either SCSI or ATA HDs. The webpage will be dynamic. 1)How many concurrent connections would something like this handle? 2) Will it make a big difference if I use SCSI or ATA? Example SCSI 1000 conncetions, ATA 100 connections. Just want a ball park figure if there is a difference. 3) How much RAM do I need for 1000 conncurrent connections? 4) Should I use RAID 1 or 5? Will it make a big difference if I want 1000 concurrent connections?

help displaying results from a mysql query with php
Can someone please tell me what's wrong with the following code? This info
is inside a function that I defined. One of the arguments that I pass the
function is the actual query. Based on the info that I know is loaded in
the database (it's a development database...there are only 2 rows of info),
the query I define only returns two answers. In case you're wondering...the
query works fine from within mysql, no problems there. The problem seems to
lie in the loop construct. It displays the first record fine. But the
second record comes up as an invalid index reference. Someone help... How
do you all display your results? I know there is another while() that I've
seen used, but I can't remember the syntax. And I'm new to this by the
way...
$result = mysql_query($query);
$num_results = mysql_num_rows($result);
if($num_results)
{
echo I have located .$num_results. results that match the
information you provided.;
}
$i = 0;
while($num_results $i)
{
$row = mysql_fetch_row($result);
echo p . ($i + 1) . Display the queried info: ;
echo htmlspecialchars( stripslashes($row[$i]));
echo /p;
$i++;
}

Re: Problem with select.
Without an ORDER BY, there is no order. Any order you see is purely accidental. If no order is requested, how could it be quicker to read through the index, and jump madly about the table extracting small records from large buffers. A linear read from the table is much faster.

RE: how do you define a relationship?
Perhaps what is confusing you is that you never explicitly define a relationship as such: there are no relationship objects. Rather, at the table leve you define a foreign key that references the primary key of another table. Second, you must use the InnoDB or BDB table types to get foreign keys. Both tables have to be InnoDB type and there must be an index where the foreign key and the referenced key are listed as the first columns. InnoDB does not auto-create indexes on foreign keys or referenced keys: you have to create them explicitly. Finally, here is the (relevant part of the) syntax: [CONSTRAINT symbol] FOREIGN KEY (index_col_name, ...) REFERENCES table_name (index_col_name, ...) [ON DELETE CASCADE | ON DELETE SET NULL] Just tack a clause like this onto the end of your CREATE TABLE statement. If your tables are already built, then you can use ALTER TABLE instead. Look in the manual under CREATE TABLE and ALTER TABLE. hth, Arthur -Original Message- From: Hammons Randy G SSgt 612 ACOMS/SCXX [mailto:Randy.Hammons;dm.af.mil] Sent: Monday, October 21, 2002 3:48 PM To: [EMAIL PROTECTED] Subject: RE: how do you define a relationship?

From: Arthur Fuller [EMAIL PROTECTED] Unfortunately that oversimplifies the situation. A least a few movies have more than one director. My motto: Generalize for the norm; specialize for the exception. The vast majority of movies have but one director. And I suspect that movies with multiple directors have but one who is primary. Keep a single director field, with a second NULL FULLTEXT field for additional directors. The NULL test for the normal case is much cheaper than what you have to go through by assuming that ALL movies have multiple directors! This is how books are handled in large databases. Each has a primary author, and may contain secondary authors. There is no assumption that large numbers of books have multiple, equal authors. This way, you can easily and conveniently list multiples as Speilberg (et. al.) without doing joins. An interested browser can then go further to find out who the others are. In the other case, each request for a director requires a JOIN. Of course, your particular application may be director-centric, like if you're building a special database to support research on directors. But if it's just a general-purpose movies database, why bog the whole thing down just to suit a few exceptional cases?

You're still constrained to a maximum precision that matches that of DOUBLE, and you get the inefficiency of storing values as strings but you don't have to worry about rounding errors. (unless you're recording truly enormous sums of money...) -JF -Original Message- From: gerald_clark [mailto:gerald_clark;suppliersystems.com] Sent: Wednesday, October 23, 2002 10:10 AM To: Jan Steinman Cc: [EMAIL PROTECTED] Subject: Re: Rounding floats Oh, for BCD floating point.

Vague error message...
A colleague asked me what was wrong with this query: mysql select user.id, email, count(click.id) as c from user, click where when_signup = '2002-11-10' and click.user_id = user.id group by c; ERROR 1056: Can't group on 'c' Of course, it's logically impossible to group by the result of an expression involving an aggregate function and my colleague certainly knows better -- he just spaced out a bit. That said, the error message here wasn't useful in helping him to diagnose the problem. It would have been far more useful for the error message to be more clear about *why* one cannot group on 'c'. -JF - 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: RedHat 8 and mysql-server-3.23.52-3
My dear friend, TCP/IP is a protocol with KNOWLEDGE at ICMP level(see RFC792 ). The DNS server have a different purpose(see RFC 1034 or RFC 952 HostNames table). Ping work at ICMP level. The KERNEL is responsible about what is happened in the OS including the TCP/IP protocol. The TCP/IP IPV4/IPV6 and functions like socket(),accept(),listen(),bind()...etc are implemented on the KERNEL level...also the sockaddr structure type and many others. Functions like gethostbyname(),gethostbyaddr(),res_init,res_query()...etc and hostent structure type are implemented in glibc. Without all this, the TCP/IP communication CAN NOT EXIST. MySQL have the own way/functions for resolving hostnames but which is based on the glibc functions. The glibc defines the SYSTEM CALLS and others functions and it used by the C/C++ compiler. In fact by adding IP address in /etc/hosts, the glibc function gethostbyaddr() reserve the RIGHT MEMORY SIZE FOR IT(seems to be a recast to int type). If the IP address/Alias is not present in hosts, this function make an wrong allocation memory and for this MySQL daemon is crashed. That's it. In my previous e-mail i don't say nothing about Domain Class(A,B,C) or canonical name or reverse lookup or other things which is on DNS responsibility.I try to say about how it work and was my wish to not to be too technical.

AFAIK, IP-to-hostname mapping isn't done by _kernel_ functions. At least the Linux kernel knows very little about hostnames. Some exotic Unixes may implement this differently, but no operating system I'm aware of has kernel interfaces for name resolution. Making the server recognize the client correctly with an updated /etc/hosts seems logical enough. It's strange, though, to have to make changes on the server for clients to be able to connect. For using this functions IS NEED TO HAVE the properly system call library which is(in this case) GLIBC.2.2.40.If some incompatibilities(BUGS) exists between this, a lot of problems can be raised after compilation.For this reason EGOR send a strongly message to all to make a downgrade to a version of glibc which is stable. Here you get it right. glibc is much more responsible for ip-hostname-mapping than the operating system kernel itself. Kernel implements the IP protocol with dotted-format addresses, and it expects user-mode libraries to do any necessary conversions. That is, when you do this: ping www.google.com the ping binary calls a couple of conversion functions in user-mode libraries so that it can pass a real IP address to the kernel/protocol interface. Personally, i can't do that because i have installed and others applications which require this version(2.2.40) of glibc.For me was a compromised solution because i use Red Hat 8.0 and MySQL 4.0.4 for testing purpose.My applications run under Suse 7.x with MySQL 3.x (MyISAM). The problem was for who which make have installed MySQL from Source Distribution or Red Hat distribution.

full-text performance question
I have a table with a full-text index that spans four text columns. It
seems that the more records a query matches, the longer it takes to
execute. Is that normal?
Examples:
I have 15,376 records in this table:
mysql select count(*) from NS_articles where
match(artHeadline,artTagline,artByline,artText) against('foobar' IN
BOOLEAN MODE);
+--+
| count(*) |
+--+
|0 |
+--+
1 row in set (0.00 sec)
mysql select count(*) from NS_articles where
match(artHeadline,artTagline,artByline,artText) against('trucks' IN
BOOLEAN MODE);
+--+
| count(*) |
+--+
| 59 |
+--+
1 row in set (0.10 sec)
mysql select count(*) from NS_articles where
match(artHeadline,artTagline,artByline,artText) against('football' IN
BOOLEAN MODE);
+--+
| count(*) |
+--+
| 1823 |
+--+
1 row in set (1.81 sec)
mysql select count(*) from NS_articles where
match(artHeadline,artTagline,artByline,artText) against('nebraska' IN
BOOLEAN MODE);
+--+
| count(*) |
+--+
| 9673 |
+--+
1 row in set (3.29 sec)
As you can see, as the number of matching records grows, the length of
time for the query to execute gets longer (pretty much linearly.) Why is
this? If I had 1,000,000 rows, I would presume the query would take a
_very_ long time.
TIA

RE: Optimizing Query to use Index in ORDER BY
What version of MySQL are you currently running? There exist a feature in release 3.23.x where a filesort will be used to perform GROUP BY and ORDER BY's actions when the key part is not used in the where clause. If I am correct, the optimizer has been tweaked in version 4.x. Forgive me if I am off base with this information. I hope this helps.

match against ('best') bug?
Hi-
I don't know if this is a bug (I'm pretty new at mysql),
but I figured I would fill out the report anyway. I don't know how to answer some of
the questions, but did my best.
I have looked in the manual, searched the list archives,
and am using 4.0.4-beta-max-nt on Win2000.
Description:
Whenever I perform a match against the word best [and,
interestingly, only the word best by itself, because (+best +friends) and (friends
best) both DO work] using
match against, I get an empty set. If I use like '%best%'the correct records are found.
How-To-Repeat:
CREATE TABLE booleanbug (
id int(11) NOT NULL auto_increment,
name char(40) NOT NULL,
PRIMARY KEY (id)
);
#
# Dumping data for table 'booleanbug'
#
INSERT INTO booleanbug VALUES ( '1', 'Best in Show');
INSERT INTO booleanbug VALUES ( '2', 'Star Wars');
INSERT INTO booleanbug VALUES ( '3', 'Hannah and Her Sisters');
INSERT INTO booleanbug VALUES ( '4', 'Best Friends');
INSERT INTO booleanbug VALUES ( '5', 'Office Space');
INSERT INTO booleanbug VALUES ( '6', 'The Professional');
INSERT INTO booleanbug VALUES ( '7', 'Terms of Endearment');
INSERT INTO booleanbug VALUES ( '8', 'Father Knows Best');
INSERT INTO booleanbug VALUES ( '9', 'The Flamingo Kid');
INSERT INTO booleanbug VALUES ( '10', 'Repo Man');
CREATE FULLTEXT INDEX name on booleanbug(name);
select id, name from booleanbug where match(name) against ('best');
select id, name from booleanbug where match(name) against ('+best IN
BOOLEAN MODE');
#[BOTH OF THE ABOVE SELECTS RESULT IN EMPTY SETS]
select id, name from booleanbug where match(name) against ('+best
+friends IN BOOLEAN MODE');
select id, name from booleanbug where match(name) against ('wars');
select id, name from booleanbug where name like '%best%';
#[ALL 3 OF THE ABOVE SELECTS WORK]
# NOTE - I called the test case table booleanbug,
# but have since realized it's not just a boolean
# problem. For some reason match against ('best')
# doesn't work for me, boolean or not.
Fix: no idea
Synopsis: match against ('best') doesn't work

On Oct 21, Jakob Nielsen wrote: In scenario 1 I'm using this SQL-statement: SELECT * FROM tArticles WHERE ( Title LIKE '%HYDRO%' OR Body LIKE '%HYDRO%' ) In scenario 2 I'm using this SQL-statement: SELECT * FROM tArticles WHERE ( MATCH( Title, Body ) AGAINST( 'HYDRO')) My problem is that if I'm searching for a word (For instance HYDRO) that are found in a lot of my articles, then scenario 1 is much faster than scenario 2. But if the search word is in just a few of the articles then scenario 2 is _much_ faster than scenario 1. Can someone explain this to me? What do I do? Yes, it's a well known issue. There're two reasons for this. The first one is that when you select too many rows, it's faster to do a table scan - reading the file in sequential order - than scan the index and read row data in some random - implied by the index - order. That's why MySQL doesn't use index if it's expected to select more that one third of the table. But fulltext search (in 3.23 at least) cannot work without an index. The second thing is that fulltext search - as implemented in 3.23.x - uses some complicated statistics to produce adequate relevance rating (optimized for natural language queries). To do it, it keeps a list of all matched rows. Actually, not a list but a binary tree, so lookup time is O(log(N)). So search time is O(N*log(N)), while search time for LIKE grows linearly. Second issue can be resolved by using fulltext search IN BOOLEAN MODE (available since MySQL-4.0.2), it's not optimized for natural language queries and doesn't need these complicated relevance calculations. So it's O(log(N)) times faster than fulltext search in natural language mode and almost always faster than LIKE.

Re: MySQL not starting.
One line says : The file /usr/local/mysql/libexec/mysqld doesn't exist or is not executable Does it exist? Is it executable? Is it owned my mysql? Does mysql own /usr/local/mysql and all its subdirectories and files? Another line says ./mysqld: Can't change dir to '/usr/local/mysql-3.23.52-pc-linux-gnu-i686/var/' (Errcode: 2) Error 2 means that the directory doesn't exist. Does it? Does mysql own it and all its subdirectories and files? Why is one directory /usr/local/mysql and the other /usr/local/mysql-3.23.52-pc-linux-gnu-i686 ? It looks to me like the log is telling you everything you need to know to find the problem. [EMAIL PROTECTED] wrote: I have tried both as myself and as root and received the same results.

relevance ranking with IN BOOLEAN MODE
Hi,
How do I get a full-text relevance ranking when using IN BOOLEAN MODE?
The manual shows how to get the relevance, but if I try to apply the
same technique to a boolean search, I get a score of either 0 or 1 as
the relevance. There are relevance parameters for boolean searches,
so it must be possible?
select match(artHeadline,artTagline,artByline,artText) against('trucks'
IN BOOLEAN MODE) as score from NS_articles where
match(artHeadline,artTagline,artByline,artText) against('trucks' IN
BOOLEAN MODE) 0;
query returns:
+---+
| score |
+---+
| 1 |
| 1 |
| 1 |
| 1 |
| 1 |
| 1 |
| 1 |
| 1 |

Re: Another bit off-topic question
Hello. On Wed 2002-10-23 at 10:47:28 -0400, [EMAIL PROTECTED] wrote: I'm planning on using Win2k Adv. server, IIS, MYSQL, PHP on a dual processor 2.4GHz processor with 1 or 2GB RAM, with either SCSI or ATA HDs. The webpage will be dynamic. 1)How many concurrent connections would something like this handle? The short answer is: it depends. The long answer: Since you mention both, IIS and MySQL, it is not clear what you refer to. Concurrent web connections or concurrent database connection. Either way, concurrent connections is not a meaningful measure, as performance also depends on time needed per request, i.e. 10 concurrent connection with a response time of 0.1 seconds is better than 50 concurrent connections with a response time of 10 seconds (the former can answer 100 requests/sec, the latter only 5). The performance of the setup depends on many factors, among other things: - CPU speed / number of CPUs - disk space + speed + latency - memory size + free mem for database buffers + free mem for OS file caching - database usage + whole size + size of regularly used parts - usage pattern (i.e. the queries) + read/write ratio + complexity of queries - operating system + quality of threading support - MySQL + required version + required table type That are only the most common of the factors. Even if all of them were known it would still be hard to make a reasonable guess. You provided less than half of them, so the answer must be: it depends. Btw, the simplest scaling possibility you have, if needed, is to install two servers, one for the web server part, one for the database server. A data point: A dual Pentium III 1133MHZ, several 18GB IBM SCSI disks, 2GB RAM (0.5GB used, 0.5GB used for caching, rest sparely used), only for MySQL. Linux 2.4, ext2 filesystem. Seperate app server. Database is 15GB, of which no more than 1GB is often used. About 40 Million records. 80% simple SELECTs, 10% SELECTs without perfect index, 10% writes. MyISAM tables on v3.23.49. Indexes and tables are optimized a lot. This setting is able to handle about 120 queries/s, where one web request triggers about 8 queries, i.e. 15 request/s with a CPU utilisation of 20% and disk throughput of 400MB/s. Experience tells that this system on this database manages to sustain 2GB/s, so CPU usage will become first bottleneck at about 75 req/sec resp. 600 queries/sec. For this application, RAID/SCSI/IDE is a non-issue for now, because the relevant database parts are cached (by the OS) in memory, and there is room for the database to about double the size before the cache ratio will get worse. The CPU requirement is unusually high due to certain shortcomings of the 3.23 optimizer, which are already fixed in the 4.x tree (so I do not care and plan to switch to 4.x when CPU becomes a problem). Additionally, the query cache of 4.x will benifit my kind of application *a lot*, so expect to get up to 4000-5000 queries regarding the CPU, but some other bottleneck will hit me first. When the database is 5 times the size, the situation will have changed completely (given the same hardware), because the relevant parts cannot be cached anymore - the disk throughput increases - the disks are too slow - the whole system bogs down. A RAID system may be able to partially compensate for this (or simply buying new mem, which will be cheapier by then). 2) Will it make a big difference if I use SCSI or ATA? Example SCSI 1000 conncetions, ATA 100 connections. Just want a ball park figure if there is a difference. It depends. ATA is about as fast as SCSI or faster for a single disk. For several disks, SCSI has less congestion and will be faster. (Only high usage disks count for this number, not a disk holding the system.) There are other advantages to SCSI which have nothing to do with speed. 3) How much RAM do I need for 1000 conncurrent connections? What kind of connections (see above)? MySQL's memory usage is quite configurable. According to my experience the web server will use more memory than the database per connection. But you want a key cache of a reasonable size for your database. 4) Should I use RAID 1 or 5? Will it make a big difference if I want 1000 concurrent connections? If you are concerned about disk speed, RAID 1 or RAID 10 is the way to go, if you can afford the needed system and disks. But be sure that you need a RAID system at all (regarding the speed issue). Btw, using a UNIX system like Solaris, FreeBSD or Linux will give a significant speed boost for MySQL (up to 30%, IIRC).

Help Please ... PHP Problem - /libraries/grab_globals.lib.php
I still can't get get PHP working - Apache and MySQL work fine, but loading PHP pages continually show errors such as: Fatal error: Failed opening required './libraries/grab_globals.lib.php' Compiling from source presented a lot of dependency issues, so I reinstalled everything via deb files - phpmyadmin, apache, and php4, and uncommented appropriate httpd.conf lines: AddType application/x-httpd-php .php LoadModule php4_module /usr/lib/apache/1.3/libphp4.so Typing localhost in the browser loads docroot ok, and the phpinfo test page works fine, showing all the php config settings. I thought I was all set! http://localhost/test.php However, nothing else with .php, .php4, .php3 works at all. They fail with various errors, one of which is the following: Fatal error: Failed opening required './libraries/grab_globals.lib.php' (include_path='.:/usr/share/pear') in /var/www/index.php on line 8 I tried copying all the files from where I originally tried to compile php, into /var/www/, but it didn't work (dumb guess anyway): /usr/php-4.2.3/pear /usr/php-4.2.3/pear/scripts/pear Can someone give me a suggestion?

Using the embedded mysql server - how do I create a database on the fly?
Hello.
I'm just getting started with the embedded mysql
server and I'm not trying to do anything fancy. I
just want to initialize the server and call
mysql_create_db and have the database get created
and then start using it.
I've modified the basic embedded server example as
follows:
mysql_server_init(sizeof(server_args) / sizeof(char
*), server_args, server_groups);
if(mysql_create_db(one, my_database)) {
fprintf(stderr, Failed to create new
database. Error: %s\n, mysql_error(one));
}
one = db_connect(my_database);
two = db_connect(NULL);
db_do_query(one, SHOW TABLE STATUS);
db_do_query(two, SHOW DATABASES);
mysql_close(two);
mysql_close(one);
I get a test_mysqld.c:53: warning: implicit
declaration of function `mysql_create_db' when
compiling and then I get a Seg Fault when it is ran.
What am I doing wrong?
