Problem with replication
SQL Hi all! Nearly very night I have this problem. This query is done every 3 hours. But problem is happened only at 3:00 Both master and slave are 4 CPU (2 with HTT) computers. Both have mysql 4.0.16 And when I test table analit. There are many records which have the same conditions as in WHERE statement. This records are inserted into analit before this UPDATE. UPDATE finds records on master, I have checked the records on master and I see the result of UPDATE. But there is the error on slave server. If I run any query on analit like select count(*) from analit where label=1070931600 and after this SLAVE STOP; SLAVE START problem is solved. Is it a bug in server? Can mysqld break the order of replication query on multy-CPU computers?

Re: replication/binary log
Use PURGE {MASTER|BINARY} LOGS TO 'log_name' instead of RESET
MASTER.
From the manual:
Deletes all the binary logs listed in the log index that are strictly
prior to the specified log or date. The logs also are removed from this
list recorded in the log index file, so that the given log now becomes
the first.
(...)
You must first check all the slaves with SHOW SLAVE STATUS to see which
log they are reading, then do a listing of the logs on the master with
SHOW MASTER LOGS, find the earliest log among all the slaves (if all the
slaves are up to date, this will be the last log on the list), backup
all the logs you are about to delete (optional) and purge up to the
target log.

wonder how this will affect replication. Is this going to break replication

Dear All, Please comment on Best Practices for sharing members database between different portals. Suppose we have 3 portals running on different networks. Assignment is to make a single Login/Pass for all portals, means once LogedIn in one of the portal, could able to access the other portals without loging In. Constraints are, every portal have different Database structure and also have different Global / Session variables. Please share your experience and which approach is the best practice. Regards, TM

Running MySQL Daemons with same data files
Dear All, I am working in Linux 8.0 and running mysql 4.0.16. I am trying to access same data files from the two mysql daemons. I mean there are two PC's running with mysql and one NAS server where data files are kept. To run mysql on the machines I first mount the NAS file system and then run it like shellsafe_mysqld --datadir=$PATH_TO_DATA_FILE) Daemons are running well but there is problems with synchronization of the data files i.e when i insert some tuples in the tables its not immediately writing then to file its kept in the cache only and when I try to see from the other machine its displaying the old tuples. I want after every transaction or query the database update the data files, how can I do this? And always read from the data files for select operations. My main aim is no cache operation to use the mysql as file system(for every operation file operations only), I know it will degrade the database performance but its the requirement OR if there is any other way by which I can achieve this, please tell me. regards bhartendu -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
Delayed Insert Question
Hi list, I've got a small MyISAM table which is used for some statistics. I'm only doing insert into this table. I need that clients doing INSERT queries can exit as soon as possible. So, i'm using INSERT DELAYED with some good succes. But I've got a question. If i decrease delayed_insert_limit to ten secondes for example, is that mean that delayed_queue will be flushed every ten secondes ? Is there an other variable that specify the flush time ? For the moment, MySQL can handle an average of 92.12 query/sec. Thanks.

RE: ?? .tcshrc On OS X ??
.tcshrc is the config file for your settings on the environment variables for your session of tcsh. When your looking for $SHELL your looking for the command line interpretor.

If you increase delayed_insert_limit then you're effectively giving the DELAYED thread more preferencee to the table; it will write more rows (once it can, ie there's a phase of time where there's no locks on the table) in a batch, which potentially makes other selects wait longer. Inserting delayed_queue_size means the clients can pile more and more rows into the DELAYED thread while it gets chance to write.

running mysql 3.23 and mysql 4.0 on same linux/suse box
Hi there,
I'm having problems running two versions of mysql simultaneously on the
same box.
The versions I'm using are:
* mysql 3.23.48
* mysql 4.0.16
What happens:
* I have the 3.23 version up and running (can see that it has 5
processes running with ps,
and 'bin/mysqladmin status' shows that it's nicely running locally
* When I start up the 4.0.16 version it seems to bring down the 3.23
version... First,
the 4.0.16 version itself starts up with error messages and the 3.23
can no longer be
queried ('bin/mysqladmin status' says it cannot connect). The error
message from the
4.0.16 startup is:
'Can't start server : Bind on unix socket: Permission denied'
What I did with the 4.0.16 is to have it run on a different socket file.
Anyone can help me out on this? What could go wrong when you have two
versions
running? Am I running with wrong user? But then, why does the start of
4.0.16
somehow crash the 3.23 version (the processes of the 3.23 version are
then still
there but not reachable. Killing the child processes of the mysql daemon
brings
3.23 up and running again)?
Thanks for any help!
cheers,

If that returns what it should, then take reference_number from the results and lookup in images using it: SELECT image_filename FROM images WHERE reference_number=[reference_number]; (where [reference_number] is from the previous result) If the first query returns nothing, then your problem is that there's no record for properties.country='Spain'. If the second returns nothing, then there's no record for images.reference_number matching Spain's reference_number in properties.

HTTP 404 is an error code, when you try to reach a file, what is not exist. For example, if you have a webserver, http://mydomain.com and you have only an index.html nothing else, if you write http://mydomain.com/myfile.html then you will get this error, because myfile.html is not an existing file.

Creating temp table is causing locking?
Hello all, I'm having an issue with mySQL that causes some poor performance. I'm running mysql Ver 13.5 Distrib 4.1.0-alpha, for portbld-freebsd5.1 (i386); front-end is Apache 1.3.27 with PHP 4.1.1. My database is using all MyISAM tables, with 50 or so tables and about 60MB of total data. My overides on variable defaults are: [mysqld] set-variable = max_connections=500 set-variable = table_cache=128 set-variable = key_buffer_size=32M set-variable = query_cache_size=32M set-variable = long_query_time=3 set-variable = tmpdir=/usr/tmp CPU use on the mySQL server is usually 20% - 30%; but every so often it jumps to almost 100% and remains there for some time. My site slows to a crawl. When I check SHOW PROCESSLIST I see a large number of processes in 'Locked' status, and one as 'Creating tmp table'. When I manually kill this process, the server returns to normal. I turned on slow query logging and general query logging, and I'll be looking through them for any strange queries, but aside from that, is there anything I can do to prevent this locking issue?

MySQL 4.1.1 create table : why negatives values need quotation marks?
Hi. First, sorry, if my problem is know or documented. I have made a rapid search on the MySQL site, but without success. Here is my problem : the following 'create table' command refuses to execute on 4.1.1, if -1 is not put between a quottation mark: create table testTable (name varchar(10), age smallint default -1); If the value -1 is changed into '-1', the command works. Is this the correct behaviour in 4.1.1 ? An application here (written by a colleague) was using numbers without quotation marks as default values in the create command. The application worked untill today. Before he updates the code, I would like to have more precisions. Following is the output of the create commande with a 4.1.1 and a 4.0.3 MySQL server. mysql select version(); +--+ | version()| +--+ | 4.1.1-alpha-standard | +--+ 1 row in set (0.00 sec) mysql create table testTable (name varchar(10), age smallint default -1); ERROR 1064 (42000): You have an error in your SQL syntax. Check the manual that corresponds to your MySQL server version for the right syntax to use near '-1)' at line 1 mysql select version(); ++ | version() | ++ | 4.0.3-beta-max | ++ mysql create table testTable (name varchar(10), age smallint default -1); Query OK, 0 rows affected (0.01 sec) Does somebody have the same problem ?

Re: Comparing strings containing possible quotes
Three messages quoted, with my responses interspersed: zzapper wrote: [8 Dec 2003 19:07:49 -] Hi Ya, I have a typical select as follows SELECT * FROM ytbl_development AS t1 WHERE (t1.txtDevName LIKE '%#form.searchtext#%') However users a complaining that if they search for for a name that contains a quote eg a development named King's Reach it is not found. A) Now it simply won't match King's Reach whether I include the quote or not. WHY?? (Have the quotes been converted ie to URL Encoding)) Consider what your query looks like when form.searchtext contains a single quote. Using your example, you get: SELECT * FROM ytbl_development AS t1 WHERE (t1.txtDevName LIKE '%King's Reach%') The single quote in King's completes the quoted string! I'll rewrite it with a newline for emphasis: SELECT * FROM ytbl_development AS t1 WHERE (t1.txtDevName LIKE '%King' s Reach%') s Reach%' is not valid SQL, so I expect that if you checked, you would find that mysql is throwing a syntax error in this case (or waiting for the 4th '). B) Now I can filter any quotes from form.searchtext easy enough, but how do I filter them the Left Hand Side eg from txtDevName?) You don't want to filter the quotes from the input string, because they exist in the data. (Well, you could filter from both sides, but that's inefficient.) What you need to do is escape the quotes with backslashes before sending them to mysql. Then your query will look like this: SELECT * FROM ytbl_development AS t1 WHERE (t1.txtDevName LIKE '%King\'s Reach%') So, you need to replace ' with \' in your form.searchtext. I'm not familiar with ColdFusion, but I expect you can use a variant of the replace function you mention below to do the job. PHP has a single function call to handle escaping text -- perhaps ColdFusion does as well? I look forward to seeing how you solve this. [9 Dec 2003 10:59:11 -] Is there no mysql solution to this? Most Where clauses are thus WHERE LHS Like/= RHS Now MySQL provides lots of operators for the RHS eg WHERE LHS RLIKE RHS But what I want to do is preprocess/filter the LHS before doing the comparison, I can find no information on this. In the past I have cheated by creating an additional column in my database eg txtDevNameClean which has all non-alphanumerics removed. am I barking up the wrong tree?? I think so. As I described above, I think the problem is with your query, not mysql. Hence, you must escape the search text on the application side to ensure valid SQL before sending to mysql. Note that single quotes are not your only worry. As your form stands now (I'm assuming based on the piece you've shown), imagine what could happen if the user entered something like King'); DELETE FROM TABLE ytbl_development WHERE txtDevName LIKE ' as the search text (form.searchtext). You would end up with SELECT * FROM ytbl_development AS t1 WHERE (t1.txtDevName LIKE '%King'); DELETE FROM TABLE ytbl_development WHERE txtDevName LIKE '%') The moral is that you should always validate user input before passing it to mysql. [9 Dec 2003 11:54:58 -] Hi Ya. I seem to have solved my problem if I clean out any punctuation from my search string (see below (ColdFusion script)) cfset form.searchtext=replace(form.searchtext,'[[:punct:]]','','all') When I perform the WHERE LHS-Containing-Quote LIKE RHS-without-quotes The LIKE appears to ignore the quotes (which is what I want) BUT IS THAT A FEATURE OF LIKE??? It's hard to say without seeing the query. I don't believe LIKE ignores quotes, but if your wildcard (%) is in the right place, it could seem to. I think your emphasis on LHS versus RHS is confusing the issue. If you'd like to pursue this, post your query and the results you get so we can see what you mean.

RE: Is mySQL right for me??
From what you describe, I have to wonder if a database is even truly appropriate for the situation at all. How large is the data set in question? If it's very small, save for actual image data (which could be stored as files) the question becomes how often and under what circumstances the data will *change* If it's relatively fixed then why not hard-code it in an include file (or encode it as XML and slurp it in via whatever nifty mechanism ASP provides for doing so)? Assuming that a database is the appropriate solution here then MySQL should be just fine. -JF -Original Message- From: GREG BARBER [mailto:[EMAIL PROTECTED] Sent: Monday, December 08, 2003 7:21 PM To: '[EMAIL PROTECTED]' Subject: Is mySQL right for me?? Hi All, I want to create a small database that allows a user to populate a report by choosing many different parameters whcih are linked to a variety of images and text entries. The front end would be HTML/ASP based and would feature several choices that the user makes to define what is included in the final report or form. The output would then be printed and forgotten about. The next user could then come along and create their own custom page from the options available. Is mySQL capable of creating such as system?

Re: Best practices for sharing members database between different portals
On Tue, 09 Dec 2003 15:26:10 -0600 Tariq Murtaza [EMAIL PROTECTED] wrote: Please comment on Best Practices for sharing members database between different portals. Suppose we have 3 portals running on different networks. Assignment is to make a single Login/Pass for all portals, means once LogedIn in one of the portal, could able to access the other portals without loging In. Constraints are, every portal have different Database structure and also have different Global / Session variables. In one word, webservices, more specifically the nuSoap library (for PHP). Take the user databases out of the 3 portals and unify them in one place. Add an interface (webservice server) in front of the user db that will handle user authentication and session tasks. Add code in the 3 portals that will talk SOAP to the user db interface, thus making the portals webservice clients. The beautiful part is, the portals can have completely different databases, languages, or webservers. They just each need a bunch of functions that speak SOAP and that implement a common user auth/session API. If you're worried about having to connect to the user db for each page a portal serves, you can cache the session ID locally in each portal's own database after the authentication. But you'll run into some other issues this way. There's however one big problem I see here: I don't see how you're gonna convince a browser to remember state information from one site address and apply it automatically to the other two portals upon login. You can't set cookies for other domains. -- Skippy - Romanian Web Developers - http://ROWD.ORG -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

From the manual:
Deletes all the binary logs listed in the log index that are strictly
prior to the specified log or date. The logs also are removed from this
list recorded in the log index file, so that the given log now becomes
the first.

You must first check all the slaves with SHOW SLAVE STATUS to see which
log they are reading, then do a listing of the logs on the master with
SHOW MASTER LOGS, find the earliest log among all the slaves (if all the
slaves are up to date, this will be the last log on the list), backup
all the logs you are about to delete (optional) and purge up to the
target log.

That worked quite nicely, thank you :) Is there some reason why
MySQL keeps these log files ? Why wouldn't it delete them as a
new one got created?
thanks
You can also use those to restore a database that is lost somehow.
Just run all the binary logs and pipe them into mysql from the last
snapshot you have taken a backup from.

RE: New to joins - this simple one doesn't work.
. Dear List, My thanks to those who replied.

I can thus stick all the fields in the one table and, with that, my need for Joins goes west. While this now needs loads'v table reconstruction, at least I'm well able in that area.

In that case you'd be right back at the drawing board. If you build it that flexible from day one, though, he can change his mind to his heart's content.

Popper mysql db problem
I'm new to MySQL, so this might be a stupid question/problem, but I can't figure out the answer: I'm trying to install the Popper webmail client on my web server. I'm following the instructions exactly. It told me to log in to the mysql console with mysql -u root -p and then create database popper, which I did. It then said to GRANT insert, update, select, delete, alter, drop, create ON popper.* TO [EMAIL PROTECTED] IDENTIFIED BY 'theuserpassword'; I changed the [EMAIL PROTECTED] to [EMAIL PROTECTED] and the 'theuserpassword' to an appropriate password, but whenever I switch to the mysql user account and mysql -p popper and put the specified password in, it gives me a ERROR 1045: Access denied for user: '[EMAIL PROTECTED]@localhost' (Using password: YES) I've even tried mysql [EMAIL PROTECTED] -p and it gives me the same error.

Production problem porting from PHP to ASP
Dear Members, For the last two years we have had a large software application written in PHP 4.0.6 with a MySQL 3.23.56 database all running on a single box with RedHat Linux 9.0. This has worked fantasticly and it is very fast. For certain business reasons that I wont go into detail here, we had to rewrite all the code from PHP to Microsoft ASP. The box that contained the MySQL database on Linux remained as is. A second box was purchased and runs the ASP code on Windows 2000 Server. The existing database on the Linux box is called by an ODBC connection on the Windows machine. The problem is that now the software runs terribly slower. The reason could not be that anything is wrong with the MySQL database since the database on the Linux box was absolutely unchanged. I suspect that the culprit is that PHP connects through a native MySQL driver, while in our new way ASP connects through ODBC. Does anyone have any ideas about this ?

Re: Production problem porting from PHP to ASP
Yes ODBC connections is considerably slower i have found, it could also be the native connections class you may be using for ASP, but why why why. Bad mistake.

ODBC is an additional abstraction layer between your code and MySQL, whereas the MySQL driver that mod_php uses is optimised for use explicitely between MySQL and PHP. There is a lot of extra baggage that you're dragging around with ODBC. Also, I assume that the app originally ran on the one box, ie apache with mod_php was on the same box as MySQL. Putting the web server on a different box and running queries across a network is obviously going to slow things down. I would also expect that IIS / ASP is slower than Apache / PHP, no matter what DB drivers you're using. So yes, your app should run considerably slower. If you post some details about what you're doing, maybe someone can give you some pointers as to how to optimise things.

Replication and failover question
I'm thinking about doing this: Setting up 2 mysql servers each replicating to the other (each a slave of the other). Code the connect/j connection creation to try one server on connect. If it fails, connect to the other server. Both servers are writeable, but my code is never talking to more than one server at a time. The one question I have here is this: DBX is replicating to DBY. DBY is replicating to DBX. If apps are writing to DBX and DBX fails, then apps will reconnect to DBY and continue writing. Is it possible that some writes from DBX haven't replicated to DBY, conflicting writes occur in DBY and when DBX is brought back online, DBY's slave SQL thread fails when it sees DBX's unpropagated writes? What are ways to get around this short of a DBA manually skipping the conflicts in DBY? Thanks

sending array data using php mail
Hi, can anyone tell me what is the problem of my script:

$rows1 = mysql_query($sql2,$linkptr1) ;
$OwnnerMail =[EMAIL PROTECTED];
$Subject = Testing;
while ( $row = mysql_fetch_array($rows1) ) {
$newvalue = $row[Password];
echo $newvalue\n;
}
$Body = $newvalue;
$From = $HP;
mail( $OwnnerMail,$Subject, $Body, From: $From);
I can see all the data for $newvalue in browser. But, when i receive email, i

Re: sending array data using php mail
hi
the error is in this line:
$newvalue = $row[Password];
make it
$newvalue.= $row[Password];
(notice ^ the dot - for concatenation with the
previous value).
and if u want to see each password in the browser too,
in that same loop, put:
echo {$row[Password]\n;
so it would now look like:
while ( $row = mysql_fetch_array($rows1) ) {
$newvalue.=$row[Password];
echo {$row[Password]\n;
}
u may also want to use a br in ur echo line to make
the browser output nicer, the \n affects only the html
code. and while u're at it, put a \n in $newline so
that ur email looks nicer.

Upgrading from 3.23 to 4.0 and trouble vith auto_increment
Hi, just got a new MacOS X Server 10.3 (Panther) that came with MySQL 4.0.14. Previous system we had was MacOS X 1.2, the really old one. I old system I was running MySQL 3.23.39 (if I now remember it right). I have good reason to believe that we made the change from old to new by the book. We took double backups from every table we had. Then we installed the new system and uploaded the databases. Everything was ok, mostly. For some strange reason, some of the tables just went berjerk. The main trouble is in the id field and it's auto_increment. Normally when I add a new line the new id is previous+1 (like 8993, 8994, 8995 ect.), but now the new id would be 0 and after that when I try to add a new line, I get the announcement: Duplicate entry '0' for key 1 The strange thing is that this does not happen in every table, just in some of them. Does anyone have a clue what is happening?
