Re: Can AUTO_INCREMENT return from INSERT function into a table ?
Check out this: http://www.mysql.com/doc/L/O/LOCK_TABLES.html User 1 must do a 'write lock' on the table, before calling the insert statement. Then User 2's qery will have to wait till User 1 calls Unlock. USER 1 === WRITE LOCK USER 1 === INSERT STOP == due to process scheduling USER 2 === INSERT (this query will have to wait until the table is inlocked SELECT last_insert_id(); USER 1 === SELECT last_insert_id(); USER 1 === UNLOCK USER 2's query will be executed It's the race condition, I am talking about. There won't be a race condition. and retrieve the returned value or $last_thread_id = mysql_insert_id(); This function will not work properly if the auto-incrementing column is BigInt, because PHP does not have a BigInt equivalent. Int or smaller works fine.

Problem with binlog (bug?)
Hi there! I'm having a little Problem with the mysql binary log which I
think could actually be a bug of some sort, though I wasn't able to try it
on a new Version of MySQL.
My system configuration is:
MySQL 3.23.41´, Win32 binary Release
WindowsNT 4.0 Service Pack 6
PII, 256 MB Ram
I am using the binary log to back up a databse called 'www' to files like
c:/server/mysql/data/www-bin.???
In this database there is a table 'satzungen', create Syntax is like this:
CREATE TABLE satzungen (
rowid mediumint(8) unsigned zerofill NOT NULL auto_increment,
titel tinytext NOT NULL,
inhalt mediumtext NOT NULL,
data longblob NOT NULL,
content_type varchar(255) NOT NULL default '',
gruppe enum('Allgemeine Verwaltung','Öffentliche Sicherheit und
Ordnung','Schulen') NOT NULL default 'Allgemeine Verwaltung',
kuerzel tinytext NOT NULL,
kennung varchar(10) NOT NULL default '',
last_change date NOT NULL default '-00-00',
PRIMARY KEY (rowid),
FULLTEXT KEY titel (titel),
FULLTEXT KEY inhalt (inhalt),
FULLTEXT KEY kuerzel (kuerzel),
KEY last_changed (last_change)
) TYPE=MyISAM;
due to some specific design reasons I use the following SQL-Statement to
write data into the file
INSERT INTO satzungen 'titel' VALUES('');
SET @rowid = LAST_INSERT_ID();
#...let's conser that @rowid now has a value of 125
#...some other statements, not concerning this table...
UPDATE satzungen SET titel='title', inhalt = 'context',
content_type='text/plain', data='data',kuerzel='kuerzel', kennung='kennung',
last_change = NOW() WHERE rowid = @rowid;
this is logged into c:/server/mysql/data/www-bin.007
what happens is that when I use mysqlbinlog --result-file=c:/log.sql
c:/server/mysql/data/www-bin.007 it gets me a mysql dump which looks like
this:
#...other statements
SET INSERT_ID = 125;
SET TIMESTAMP=1017998537;
INSERT INTO satzungen (titel) values('');
SET TIMESTAMP=1017998537;
UPDATE
satzungen
SET
titel = 'title',
inhalt = 'context',
content_type = 'text/plain',
data = 'data',
kuerzel = 'kuerzel',
kennung='kennung'
last_change = NOW(),
WHERE
rowid = @rowid;
###
#^^^ THIS IS I THINK WHERE THE PROBLEM IS - THE LOG REMEBERS MY
USAGE OF @rowid #BUT IT NEVER REMBERS WHAT I SET @rowid to (the line SET
@rowid = LAST_INSERT_ID()
###
#...other statements
when I then try to read this dump on another server (using mysql -u
username -p dumpfile.sql) which has an empty table satzungen with the
same definition as above I get exactly empty row.
So my question is: is it a design feature that variables are not dumped into
the binary log? Was this problem solved in a later version of MySQL? Am I
just blind and stupid-and is there maybe an easy workaround (w/o using
updatewhere rowid = LAST_INSERT_ID()-this won#t work for me!)
Thanks!

Updated: Lost data problem Was: Corrupt .FRM files
Hi all, Some days ago (March 11) permissions were broken in catalogue of the mySQL database. Even though the permissions were not correct any more, MySQL continued to work. We think MySQL started to work with cache (with image of tables in RAM...) instead and all this time our backup system made copies automatically from HDD (not from RAM) which means that it backed up the same file all the time! On April 4th the server and Mysql were restarted and permissions were corrected at that time. Mysql then took the data from HDD and started to work with database from March 11th. As a result we have a current backup copy now. Is there any way to recover the data that used to be stored in RAM (maybe stored in some kind of cache file on the server)? Hopefully someone has an idea on what can be done!

UNIQUE index on nullable collumn - can't alter table
MySQL 3.23.47: I want to change a column that is currently non-indexed. SessionID is a nullable int column: alter table tbl_Orders add unique SessionID(SessionID); results in Column 'SessionID' is used with UNIQUE or INDEX but is defined as NOT NULL (A throwback to version 3.22???) I have tried creating new (simple) tables with such indices and they work fine. I've also tried adding an index to an existing test table, in the same scenario as this one. I can't seem to reproduce the error under test conditions, but I simply cannot add this index! In the end, I deleted recreated the entire table with the index I was trying to create defined. It worked. Some vestige of mysql's pre-nullable-index days are still haunting it for the alter, though. -- Jamie - 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?

OpenBSD and MySql
Hi, I am using OpenBSD 2.8 and spent a frustrating evening last night trying to make MySql come to heel.

Gave up on that eventually, and tried to load the databases with: /usr/local/mysql/bin/mysql --user=root --password=Dusebig7 dancedetails bars.sql Needless to say, the same thing happenned. I am sure I am not alone in this. Found http://www.hostbaby.com - but he's using OpenBSD 3.0. Being a lazy one, I had just installed 2.8 from the site.

Re: Do any of your applications work?
me thinks hmmm, it's gotta be a troll. I'm so gullible I don't even know if it is or not. If it is, life is good. My favorite it the church lady who storms the linux groups and demands that they stop supporting this operating system because she has ample proof that it is being run on web servers that dish out pornography. This one's good too but somehow I actually think it could be real. There's no way someone could know enough about UNIX to write that letter, and then have a strong opinionated stance like that is there? Is the world that big?

Re: How can I kill the slow query automatically?
Hi Marc, Thanks for the suggestion. I hope you would be kind enought to provide another. My application is transactional, in the business sense, in that, at the point of sale, the transactions must be quick. So inventory must be updated quickly to move the people through the line. The question is would not UPDATE LOW PRIORTY make the UPDATES then wait for any slow selects to finish before proceeding, thus making the point of sale pontentialy suffer? Maybe I don't understand UPDATE LOW PRIORITY. I think in my case I have conflicting requirement, but the main focus is to move the people at the cash register out the door :) These are ususaly very quick and short queries. This conflicts with reporting and product ordering and even data mining. Which in my case could be given a low priority, but not if it locks tables, or even run without locking (as our old system did!). Any advice or discussion is appreciated.

MySQL won't keep running on my Mac OSX
I'm having trouble keeping MySQL running on my computer (PowerBook G3 -Firewire, 576MB RAM, G3/400 - 40GB HD with plenty free in the main OS X partition). I'm running OS X 10.1.3. 1. I installed MySQL (binary) in \Users\hill\MySQL\ directory (logged in as me/hill, not root) 2. I can run the install and safe_mysqld and initially get the database up and running. I can log in as root (database not OS), assign passwords. I can even load PHPMyAdmin and manage the databases. 3. If I restart the computer or log-off/log-on, I've received different errors. The main error is Error 2002: Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2). I've also gotten an error that the current user is not authorized or some other issue with password. I can't connect to the database to test out what the 'password' is supposed to be. So then . 4. If I delete the \data\ directory contents, I can reinstall and go through the process again. It will work well until I do a sleep or restart and then I must delete and do everything all over. I'm somewhat new to UNIX (used it many years ago) and don't know all the tricks, tests but am not uncomfortable digging around for fixes. And I know there are too many folks with success that it's obviously something on/about my system, but not sure where to dive in. Can someone give me an idea as to why the database won't keep running or at least some things to check for? Thanks in advance for any help. -- Jay Hill NetLearning, Inc.

Best field type for ID?
Hi everyone, What is the best field type to use for an ID field which is the primary key and auto-increment? I wanted to use SMALLINT UNSIGNED because its half the bytes of INT but was wondering what happens when it reaches 65535, does the auto-increment go back to 1 or will it cause an error?

Re: MySQL won't keep running on my Mac OSX
I have the same exact setup down to the hardware (believe it or not). Your best game plan is to install the MySQL binary distro into /usr/local/mysql as the root user. And then run the MySQL server as root. You'll have to start the MySQL Server when you start the laptop. Otherwise, you can log out or put the laptop to sleep, and the MySQL server should keep running. This setup works fine on my G3-firewire Mac OS 10.1.3 Lap Top computer. -RG On Mon, 8 Apr 2002, Jay Hill wrote: I'm having trouble keeping MySQL running on my computer (PowerBook G3 -Firewire, 576MB RAM, G3/400 - 40GB HD with plenty free in the main OS X partition).

database setup
Hi, I am setting up a mysql database, with two tables. One keeps the user authentication info such as user name, password and user level. The other table with contains files for upload and download. Is there a good way to setup the user authentication table so it can check appropriate user rights (user level) then provide the appropriate upload or download page? I came up with a scheme as follows, userlevel unsigned tinyint not null primary key, username char(8) not null, userpass char(16) not null I can store user passwords using MySQL's password encryption. But when I need to access the upload/download table I need to somehow notify the database that what level of access the user has. If I set userlevel=1 (or any number) after succesful authentication in the script, I would compromised the other table. As hackers can change userlevel in the php script without going through the authentication. Can someone please provide me a couple of pointers how I go about setting up my database? TIA.

binlog and replication stuff
Hello. I'm using MySQL-3.23.38 on 5 RedHat 7.1/7.2 servers composed by one master and 4 mysql slave, every write is made on the master and then replicated to the slave. The problem is that if one client crash or must be rebooted i've to: - on the mysql master stop mysql, delete binlogfile, tar all the data in a file and then restart mysql - on ALL the mysql slave stop mysql, delete all data, get the tar file from the master and the restart mysql so i've to restart all mysql slave even if only one is really crash, if i don't do this i loose the syncronization between master and slave (as shown in the mysql.log). As your experience what do you do when a mysql slave crash and loose the sync? I would like to use a method to restart only the crashed client without touch other's slave and without restart master. I could make a backup script that get all the data from the the master (like mysqlhotcopy) without restart nothing, but what about the binlog file? i could FLUSH them in the server but then other slave will loose the sync I appreciate any help or suggestion.

RE: Best field type for ID?
* Luke van Blerk What is the best field type to use for an ID field which is the primary key and auto-increment? I wanted to use SMALLINT UNSIGNED because its half the bytes of INT but was wondering what happens when it reaches 65535, does the auto-increment go back to 1 or will it cause an error? Should one use INT instead? The best type to use is the one big enough to hold your expected biggest value, but not bigger. If you think 65535 is too small, use the next bigger type, MEDIUMINT UNSIGNED. Don't use INT just to be sure... been there, done that... ;) when your table grows big, you will benefit from the fact that you save a byte for every column, making the indexes smaller faster. -- Roger query - 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: database setup
First, I assume that the same value for userlevel may be used by multiple users. That is, multiple users can have userlevel equal to 1 or equal to 2 or 3 or whatever. Therefore, you CANNOT use userlevel as PRIMARY KEY. PRIMARY KEY is a UNIQUE identifier. Thus, I recommend that each user be identified by a unique user_id. user_id int unsigned not null primary key, userlevel unsigned tinyint not null, username char(8) not null, userpass char(16) not null, security_key int Next, once the user is authenticated, you can pass value of user_id through sessions, to preserve security. Include with the session values a unique, random key that is generated during authentication. Store this random key in security_key. When a user makes a download/upload request, ensure that the key stored in the database is the same as that of the session. -Original Message- From: Norman Zhang [mailto:[EMAIL PROTECTED]] Sent: Monday, April 08, 2002 12:49 PM To: [EMAIL PROTECTED] Subject: database setup Hi, I am setting up a mysql database, with two tables. One keeps the user authentication info such as user name, password and user level. The other table with contains files for upload and download. Is there a good way to setup the user authentication table so it can check appropriate user rights (user level) then provide the appropriate upload or download page? I came up with a scheme as follows, userlevel unsigned tinyint not null primary key, username char(8) not null, userpass char(16) not null I can store user passwords using MySQL's password encryption. But when I need to access the upload/download table I need to somehow notify the database that what level of access the user has. If I set userlevel=1 (or any number) after succesful authentication in the script, I would compromised the other table. As hackers can change userlevel in the php script without going through the authentication. Can someone please provide me a couple of pointers how I go about setting up my database? TIA.

CREATE TEMPORARY TABLE
If I want to use temporary tables I know I can create tables that are unique without using CREATE TEMPORARY TABLE table_name. What I want to know, because it might be more efficient, is if I use CREATE TEMPORARY TABLE table_name and more than one person hits the page (I am using PHP to access the MySQL DB), does the second person have to wait until the first person is done and the temporary table is gone before the temporary table is created again, or is it unique for each connection. Example: if 100 people hit the page at the same time, will each have a temporary table called table_name that only their connection can see, meaning that there would actually be 100 tables with the same name? I sure hope that makes since.

mysql and java
Hey Guys,
I'm not sure if this is the right place to ask this question, but to be
honest I didn't know where else to turn since my script deals with mysql.
Here's my problem:
I am using stylesheets and javascript to display a small blurb about a
review on my site and it display is in a stylesheet which is only visible
when the mouse is over the link. The page is here for a reference:
http://www.hardware-unlimited.com/hardware.php (The [Description] link is
where im using java script)
Here's my ordeal, this mysql script generates syntax that is hidden from the
viewer until they put their mouse over a review for a description, however
it has to store this lil bit of syntax 90 times (beacuse I have 90 reviews
listed on the page) and it starts to add up, my page is already 132K and I
need to make it smaller. Is it possible to somehow store these descriptions
in a mysql table or on another page and then have them linked to when you
put your mouse over the link?
Syntax for descriptions is here:
?php
$db = mysql_connect( db32.pair.com, **, ***);
mysql_select_db( net3dual_reviews,$db);
$search = mysql_query(SELECT * FROM hwureviews);
while($num=mysql_fetch_array($search)) {
printf (span id='%s' class='myStyle'table bgcolor='#025689' width='300'
style='border-style: ridge; border-color: #00314F'trtdfont
face='Tahoma, Verdana, Arial, Helvetica' size='2' color='#FF'bp
align='center'Description for
%s:/bbrbr/p%s/font/p/tr/td/table/span,$num[name],$num
[name],$num[info]);
}
?
Syntax for links, displaying the descriptions is here:
?php
$db = mysql_connect( db32.pair.com, **, ***);
mysql_select_db( net3dual_reviews,$db);
$r = mysql_query(SELECT * FROM hwureviews ORDER BY num DESC);
$max = mysql_query(select max(num) from hwureviews,$db);
while ($info = mysql_fetch_row($max)) {
printf (bfont color='#ff'Hardware Reviews - %s Articles
Total/b/fontbr, $info[0]);
}
while($a=mysql_fetch_array($r)) {
printf (- a href=\%s\%s/a (Written by: a
href=\mailto:%s\;%s/a) - [a href='%s' onMouseOver='if (window.event ||
document.layers) show(\%s\,event)'
onMouseOut='hide(\%s\)'Description/a]br,$a[url],$a[name],$a[ema
il],$a[author],$a[url],$a[name],$a[name]);
}
?
I need to somehow have the ='if (window.event || document.layers)
show(\%s\,event)' onMouseOut='hide(\%s\)' syntax pull its data from a
mysql table or another page, how can I do this?
Thanks!

Should I remove the [mysqld] section from the file and start the servers from the command line using command line options and just leave the innodb/mysql-client options in my.cnf ?

Re: Reg MYSQL and JAVA
Hi, Thanks for the reply. I also need few 'doc' features such as 1. Bold letters 2.

Strange behavior
I have a table with the following fields: id=autoincrement, int (11) ts_h=decimal ts_pid=int (11) ts_day=text There is a unique record where ts_pid=60 and ts_day=2002032800 (ts_h=0). If I do [update t_timesheet set ts_h=0 where ts_pid=60 and ts_day=2002032800 ], every thing works fine. (nothing is changed because the values remain the same) But if I change the query to ts_h=1: [update t_timesheet set ts_h=1 where ts_pid=60 and ts_day=2002032800 ] The record is deleted instead of being update. I changed ts_h to a decimal, or integer, same behavior. It deletes my record instead of updating it. Any idea why this occurs? Thank you.

sum function doubling

MySQL++ (?) bug
Hi,
I've built MySQL++ 1.7.9 libs on an smp machine. But every application which
is built using mysql++ crashes with segfault when invoking connect() method.
For example:
#include iostream
#include mysql++
void main()
{
try
{
Connection con( use_exceptions );
con.connect();
}
catch ( BadQuery er )
{
std::cout er.error.c_str() endl;
}
}

I don't get where is the problem, because it crashes only on the second
server. Any help would be appreciated.
Thanks in advance :)

I couldn't find anything. Or is it just my SQL? It's your SQL. You're not specifying any criterion for joining the tables, so your result set will contain every possible combination of a row from InsertionFreq that has andersonStart_pos = 1072 and a row from DeletionFreq that has andersonStart_pos = 1072. That means if there are 2 rows like that in DeletionFreq your insFreq sum will be twice what you expected. If there's a relationship between the rows in the two tables, then use it to specify a join criterion. If there's not, then leave it as two queries the way you did first. -- Keith C.

Re: MySQL Power ?
On Friday 05 April 2002 11:32, Steve Rapaport wrote: I'm currently running MySQL for a big, fast app without problems. BUT: I'm in the middle of specifying a new application with a high load, and I'm consideing looking for alternatives to MySQL because without InnoDB, it gets really slow on tables with frequent updates and reads (no row locking). We have, for example, a session table that records all the incoming requests for holding state. Since it's constantly being updated and read, it is frequently locked, and there are often instances where 50 reads will stack up while a lock is held. This slows down the whole database. Only if you insist on locking your tables. If you're talking about a webapp, Apache only really will be servicing 1 request at a time, generally. I have yet to be forced to lock my session table. Maybe you rely too much on this one table? Also you might try using a HEAP table for session state. Its much much faster if you can afford the memory (but again, keep your session state small and simple!). With InnoDB, I'm sure this problem goes away, but as soon as we go to InnoDB, we have to pay for backups and support, which means we start looking around at 'pay' solutions. I guess I don't understand why you see InnoDB as being more expensive than using standard myisam. Its just a table handler, there are not that many fundamental differences in how things work, and 99% of the existing MySQL infrastructure works fine with any table type. Backups are pretty basically the same as ever, just back up the tablespaces! Admittedly they use the disk a bit different, but it has caused us no real problems. Is there something I'm missing? Steve However, my impression is that while the answer, for the very highest volumes, is that Oracle is better, the point at which Oracle betters MySQL is *much* higher than doubters might think. So, if anybody give the reply that Oracle is best at the high end, please could they also try to quantify the point at which MySQL begins to run out of steam - and what it is it can't do and Oracle can at that point. (For example, MySQL can handle high read loads by use of replication, but would bottleneck on high write loads - I think). - 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?
