Re: Intermitent join problems
Frank, if the tables are InnoDB type, then the following patch might fix the problem. The patch will be in 3.23.54, which, I guess, will be released around December 5th, 2002. MySQL/InnoDB-4.0.5, November 18, 2002 ... Fixed a bug: if a SELECT was done with a unique key from a primary index, and the search matched to a delete-marked record, InnoDB could erroneously return the NEXT record. If you re-run the problematic query, does it produce the correct result? The bug above was automatically corrected by the InnoDB purge after some time. Can you produce a repeatable test case?

Re: innodb and table_cache
Rafal, the table cache size limit parameter in my.cnf affects also InnoDB. MySQL is not aware that InnoDB does not open any files when InnoDB creates a handle to a new table. Hmm... I doubt that opening tables really takes much time. You can try empirically if the table cache size has any effect.

Why does altering the order alter my result?
Dear Readers, I have a little mySQL problem here. Maybe it's a bug, maybe I'm just too stupid to read the documentation correctly, who knows... I'm sorry if I bother anyone with my stupidity. I run a simpy query like: SELECT INTERVAL((UNIX_TIMESTAMP(ReceivedDateTime) - UNIX_TIMESTAMP(StartDateTime) - 86400) / 60, 360, 720, 1440, 2880, 5760) FROM Station, File WHERE File.StationId=Station.StationId ORDER BY File.FileId First I calculate the time between two DATETIME fields (in seconds), then I substract 84600 (that's the number of seconds a single day has) and divide the rest by 60 to get minutes (is there an easier way to do this? Let me know please). In the end I get a time difference in minutes that I want to compare with a set of numbers, that's what I use the INTERVAL for. If there are less 360 minutes, it should return 0, if there are less than 720 it should return 1, ... and if there are more than 5760, it should return 5. And guess what, that's exactly what it does! :-) But the result is sorted by the FileId. I don't want it to be sorted by the FileId of the file, but by a Station ID that consists out of four characters. So I modify the query like this: SELECT INTERVAL((UNIX_TIMESTAMP(ReceivedDateTime) - UNIX_TIMESTAMP(StartDateTime) - 86400) / 60, 360, 720, 1440, 2880, 5760) FROM Station, File WHERE File.StationId=Station.StationId ORDER BY Station.FourCharacterId It's exactly the same query as before, I only altered the sort order, so I expect the same result, just in a different order. But it's not the same result at all. All of a sudden the INTERVAL function seems to always return 3, because all rows have 3 as result. WHY? :-/ I just changed the search order, so how can it have such a big influence on the result? And how can I get the desired order and still get the desired result for each row? Can anyone shine a light on this issue please? -- Best Regards, Markus Hanauska - 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: MySQL on windows
Simon, I have been asked to support/bug-fix a Windows based web site using MySQL. I have used MySQL on Linux/FreeBSD for 3/4 years, but never on Windows. How does MySQL compare on Linux and Windows for stability and performance ? =congratulations. Your relief appears in the phrase, MySQL is MySQL is MySQL! =it's very difficult to answer your question because 'it all depends...'. You are probably aware (see manual) that MySQL is developed on the likes of Suse Linux and then ported. One expects then that any 'gotchas' are going to be in the ports, rather than in the 'original' environment. However I have been using MySQL under Windows for quite some time and it sits there chugging away. So, porting MySQL from one OpSys to another doesn't cause instability per-se. =as you will be well aware, a properly set up operating system is a pre-requisite for any app/service (M$ word for daemon) to be stable. Accordingly the 'Windows connection' comes down to the skill of the tech setting up the h/w and OpSys s/w. If the h/w keeps burping a fault or the OpSys can't handle something, then everything else goes down in a heap too - regardless of Win or Linux! (not seeking a religious war here, merely pointing out that there are many flavors of (in)competence!). On the other hand I'm no propeller-head and yet have had no problems (so far). =I don't recall seeing any meaningful comparative-performance specs - how could one make such a comparison 'fair and true' anyway? Then there are the real-world issues of what else the box is expected to perform, its place in the network's routing, blah-blah-blah. =One thing you may have to watch is whether you can use Win equivalents of your preferred admin/mgmt tool - if MySQLCC then you're in-to-win, but some have no Linux/Win equivalents. Another is the use of different directories/paths, but I'm sure that will be obvious enough. =Jump on in, the water's fine! =dn - 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?

Large Data Import
MySQL Gurus: I am working on a process to import data from a VMS database (SJ2) to MySQL. The table that I am importing has 10378507 (over 10 million) records in it. I have the records exported to a comma-delimited text file, as the fields within the database do not contain any commas at all. The command I am using to do the import is: mysql LOAD DATA LOCAL INFILE '/home/warehouse/importfile.txt' - INTO TABLE importtable - FIELDS TERINATED BY ',' - ENCLOSED BY ''; The process runs through (it takes about an hour into a non-indexed MyISAM table). At the end I get the following message: Query OK, 5184509 rows affected Records: 5184509Deleted: 0Skipped: 0Warnings 13376589 I have logging turned on, but the log file only shows the MySQL commands that I entered without showing me what all the warnings are. Now my questions: How can I see what the errors are that are occuring that cause half of the records not to import? Has anyone every done an import of over 10 million records before? Is there a limitation in MySQL? Thank you in advance for you assistance with this issue.

Re: table_cache too high?
If you with Linux, you can use the 'sysctl' programm. sysctl -h gives you the parameters (i.e -u is for the maximum number of processes created by a user). I use the sysctl command in the safe_mysqld script to increase this number. if you want to set a parameter systemwide you may also use /etc/sysctl.conf.

Re: Large Data Import
Well, I've done imports of about 50.000-100.000 posts from other databases.
I've gone another way then, and through perl/vi generated a file of
mysql commands
that I've then run. Maybe is a bit slower, but you get a complete log in
case some things dont
work out when you have logging turned on.
I would guess that most likely you have problems with quotation marks,
special tokens or the like
that interferes.
anyway, one way of doing it would be something like this. (
cat file | perl -e 'while($x=){chomp $x; $x=~s/,/\,\/g; print
insert into XX values(\; print $x; print \);\n }' file.sql
cat file.sql | mysql
as for limitations.. I've run databases that had 12million records in
mysql, with no
problems, except selects with criterias from that database tended to
become slow. :-)

Wrong port is shutdown with several mysql(s) running in Win.
Hello, I have several mysql 3.23 daemons running in a Windows XP Professional computer. To achieve this, I have run the following commands: mysqld-opt --basedir=C:\mysql --datadir=C:\mydb\data1 --port=3020 --standalone --default-table-type=MyISAM --tmpdir=C:\mydb\temp1 mysqld-opt --basedir=C:\mysql --datadir=C:\mydb\data2 --port=3021 --standalone --default-table-type=MyISAM --tmpdir=C:\mydb\temp2 mysqld-opt --basedir=C:\mysql --datadir=C:\mydb\data3 --port=3022 --standalone --default-table-type=MyISAM --tmpdir=C:\mydb\temp3 After running these three commands from three different ms-dos windows, I have three mysql running in ports 3020, 3021, and 3022. Now from another ms-dos windows, I execute: mysqladmin --port=3022 shutdown This command should shutdown the mysql running on 3022 but it shutdown 3020 instead. I try again: mysqladmin --port=3022 shutdown And 3021 is shutdown instead of 3022. I have concluded that there is a possible bug which always shutdown in the order of creation no matter which port you specify. I have tried the same thing in the newest version: 4.04 and it does not happen. 4.04 shutdown the port correctly. Any thoughts? Thanks. __ Do you Yahoo!? Yahoo!

Reuse MYSQL object instead of multiple connections?
Hi,
Currently, my program creates a new MYSQL object each time a connection
is needed to save or load information from my MySQL database.
Sometimes, this connection is created 10,000 or more times during one
use of the program. I'm wondering if I reuse the connection (have a
static MYSQL attribute on my database class object) if that would
improve performance at all? This is what I'm thinking of doing:
class MyDatabase {
public:
// various constructors, destructor, and query functions...
private:
static MYSQL *mysql;
MYSQL_ROW row;
MYSQL_RES *result;
};
Then the object is created once for the database that I'm working with
in the constructor for MyDatabase, and reused for subsequent queries.
Has anyone else tried this? Any other ways to do this? I'm using the C
API and MySQL 3.23.48 on RedHat Linux 7.2.
Thanks,
Anna

At the end this query returns a the correct result, but all the lines with the fields during and late in blank. The function DATE_SUB is returning NULL and there isn't more examples.

Re: fulltext, trying to index 2 character words
Hi, Sergei. In myisam/ftdefs.h I changed: #define MIN_WORK_LEN 4 to: #define MIN_WORD_LEN 2 and I commented out the line: #define COMPILE_STOPWORDS_IN (this should leave out stopwords right?)

The problem is with the types of the arguments you're giving to DATE_SUB(). It appears from your query that dthr_occurrence is a DATETIME column, so it's appropriate to use it as the first argument to DATE_SUB(). However, the expression in the second argument is supposed to be a string indicating an interval. In this case, since you've said HOUR_MINUTE, MySQL is expecting a string giving a number of hours and a number of minutes. Instead you're giving it something like '2002-11-20 12:54:43', which is not hours and minutes, so you get a NULL result. You have to give it something like '12:54', or whatever interval it is you're trying to subtract. -- Keith C.

The dreaded move from Oracle to MySQL
Well, This is my first attempt at moving from Oracle to MySQL on such a large scale and so far it isn't going well at all. We are running oracle 7.3.4.0.1 and MySQL 4.0.4-0 standard. We are moving 101 tables with a total of 45 millon records over. I have tried several diffrent methods including using a MS-SQL server to act as go between using DTS services. We have run into two problems, one, we don't get all the data over we loose rows and the like. Two it is super slow on the order of 18 to 30 hours to do a pull. We need a way to move the data in a resonable amount of time around 8 hours is the goal. Things I have tried so far include using MS-SQL as a go between fast but with data loss, using a custom ADO application to move the data and handle any transforms we get the data but it REAL slow, and trying to get the oracledump.pl perl script to run with no success. If anyone has had a chance to do this type of migration please point me in the right direction. I would really hate to stay with Oracle for the only reason that we can't get the data off of it and on to another box :) Thanks, Wes - 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: The dreaded move from Oracle to MySQL
Hi I have moved huge amounts of data around in the past, from Oracle to Oracle, and Oracle to MySQL. The problems to consider are - export speed - load speed It can take hours to download a large database, nevermind re-loading it into another database. It is usually best to export the data into a simple file that can be read whilst you are writing to it. Load speed is tricky. Do not have any indexes. Use the MySQL LOAD command, it is fast. To do this I would do the following, - on Oracle server - - Create a NFS device - - Create a FIFO pipe, using mknod - - export data from Oracle to FIFO pipe - on MySQL server - - Mount remote NFS device - - Use MySQL Load command to load data, or write your own loader in perl - - when load is finished, build the MySQL indexes I hope that this helps Simon On Wednesday 20 Nov 2002 6:24 pm, Wesley Brown wrote: Well, This is my first attempt at moving from Oracle to MySQL on such a large scale and so far it isn't going well at all.

RE: The dreaded move from Oracle to MySQL
Well, it looks like Simon has the best possible answer so far. I did a test dump into a delimited file from Oracle and imported that using the LOAD command in mysql and sustaned about 11,000 inserts a second. This is with no indexes on the mysql tables at all. I have also tried using the dbtools import function but it will ether time out or just hang on the big tables. --Simon Says To do this I would do the following, - on Oracle server - - Create a NFS device - - Create a FIFO pipe, using mknod - - export data from Oracle to FIFO pipe - on MySQL server - - Mount remote NFS device - - Use MySQL Load command to load data, or write your own loader in perl - - when load is finished, build the MySQL indexes Can you explain this procedure to me a little better or point me to something I can read? I still have to convince the person who manages the Oracle box to open up an NFS share. Another way we could increase load times would be to use 4 scripts to load data from 4 tables at once.

Re: The dreaded move from Oracle to MySQL
Can you explain this procedure to me a little better or point me to something I can read? I still have to convince the person who manages the Oracle box to open up an NFS share. The point of using NFS to transfer the files from the oracle box to the mysql box is to avoid copying the data twice. If this isn't possible (because the oracle box doesn't already have nfs set up, and the admin doesn't want to make changes...), you can copy the data via any other means. CD-R's, DLT, FTP, scp, wget, . NFS would likely be the easiest to use, and cuts out an intermediate step of copying the data to a second location, but it is not necessary.

RE: The dreaded move from Oracle to MySQL
Wesley, Forgive me because I'm not overly familiar with Oracle, and this is an unproven idea If you can run the oracle export function from unix shell, you could do something like the following -- Install the mysql client on the oracle db server (will be quick and won't need any downtime) -- grant permissions on the new mysql server to allow the newly installed remote client access to it -- make sure the mysql client on the oracle server can write to the new mysql db ok -- create all the required tables on the new mysql server's db (leaving out indicies if you want to gain performance) -- In a script (using variables and loops), run something like the following from shell on the oracle server (where t is the table name): [shell]# Oraclexportutility --tabdelim t t; mysqlimport multimaps t;sleep 5;rm -f t (where Oraclexportutility --tabdelim t is the oracle export widget that I know nothing about!!) I know that the same method works with: [shell]# mysql -B -N --execute=select * from t multimaps t; mysqlimport multimaps t;sleep 5;rm -f t If you can find a way to pipe the output straight to the mysql import utility without writing a copy to disk then that's even better! (I drew a blank at this one..) Also, if your tables are small enough to use a ramdisk for the temp table t then that's good too. You could run several of these occurences at once (although it would hammer your disks) to make the most of the bandwith available. There are lots of options to mysqlimport such as: -C, --compress Use compression in server/client protocol. -f, --force Continue even if we get an sql-error. -i, --ignoreIf duplicate unique key was found, keep old row. -r, --replace If duplicate unique key was found, replace old row. And (I quote) If one uses sockets to connect to the MySQL server, the server will open and read the text file directly. As I said, these are ideas I hope it will at least give you some ideas too...

help with a query accross multiple tables (pt 2)
Hi all,
I have the following query i'm running through a PHP script:
SELECT DISTINCT board_threads.*
FROM board_threads
LEFT JOIN board_replies
ON board_threads.id = board_replies.threadid
WHERE (board_threads.stamp '{$startDate}' OR board_replies.stamp
'{$startDate}')
ORDER BY board_threads.id DESC
Quick translation: Show threads on a msg board, only if:
a) the thread was created in the last 7 days
b) the thread has replies within the last 7 days
The stamp field in both tables is a unix time stamp.
It works as expected, and I'm happy, however, I'd liek to know a few things
(to help me learn):
1. Is there anyway this can be optimised?
2. Why was I getting SOME threads returned twice when I didn't have
DISTINCT in there?
3. Currently, the results are ordered by board_threads.id... is it possible
to order them by date? The issue is that there are multiple dates to
consider...
- board_threads.stamp
(the timestamp the thread was created)
- board_replies.stamp
(the timestamp each reply was created -- there may be zero or more
replies, so the newest stamp of these should be taken)
Any help appreciated, or links to a magical page that enables me to find out
for myself :)
Thanks,

Re: The dreaded move from Oracle to MySQL
since you're comfortable with rolling your own tools, here are some observations about the ado approach, and which could be applied to odbc as well. i'm running an oracle enterprise server in a test environment for corereader, and i've noticed that, although oracle sometimes takes a while to wake up, after you have its attention, it throws data at you very fast. sometimes a developer does not use connections properly. in your case, i would create a single connection and keep it open for the duration of the 45 million record move. after the connection is open, i would not move records. instead, i would ask oracle for the biggest record set that the infrastructure can handle. it will come back to you very fast. then i would do the inserts into mysql. when that data set is done, i would retrieve another. i would log the operation. i always expect a an operation of that size to overwhelm the infrastructure, so i would keep a running check of where the operation is. i would write that log into a local disk file. if the process crashes, you pick up from where it went down. be sure that oracle's nolog is set for every table. in fact, turn off all logging everywhere except for your app's log. also, insure that there are no indexes in the mysql side until you're finished. i'm still becoming familiar with mysql, but insure that there's no transaction logging going on. glad to hear that you had no errors before, but be careful of oracle's data typing. if you have the resources, copy the app to additional boxes. run all of them simultaneously against the servers. they'll bump into each other, but there's enough latency in all the systems to let them all operate. (hopefully, you're running on at least a hundred meg network for this.) for your operation, it would be worth it to borrow five or ten machines from the rest of the organization for a couple of days. if you run multiple apps, increase the query timeout of all of the connections. that's the way that i would do it. Well, This is my first attempt at moving from Oracle to MySQL on such a large scale and so far it isn't going well at all. We are running oracle 7.3.4.0.1 and MySQL 4.0.4-0 standard. We are moving 101 tables with a total of 45 millon records over. I have tried several diffrent methods including using a MS-SQL server to act as go between using DTS services. We have run into two problems, one, we don't get all the data over we loose rows and the like. Two it is super slow on the order of 18 to 30 hours to do a pull. We need a way to move the data in a resonable amount of time around 8 hours is the goal. Things I have tried so far include using MS-SQL as a go between fast but with data loss, using a custom ADO application to move the data and handle any transforms we get the data but it REAL slow, and trying to get the oracledump.pl perl script to run with no success. If anyone has had a chance to do this type of migration please point me in the right direction. I would really hate to stay with Oracle for the only reason that we can't get the data off of it and on to another box :) Thanks, Wes -- John Ragan [EMAIL PROTECTED] http://www.CoreReader.com/ - 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: SELECT Statement Question
thanks for the chuckle. we've all been beginners and i still do dumb things with sql. download corereader from http://corereader.com it will let you click on the database objects to build your queries. when you click on your table name and your field name, it will return the data to you and, if you care to look at it, it will show you the correct query of select * from table_name instead of your select * from postcode Hi I am a beginner in using mysql on Windows platform, and I have a question regarding the use of SELECT * from TABLE_NAME statement within the mysql prompt. I have a table of consisting of three columns POSTCODE, SUBURB, STATE where the primary key is a composite of all three fields. When I run SELECT * FROM POSTCODE; in mysql prompt I get garbled display of data and some of my data is not shown. However when viewed from within a tool like PHP MYADMIN all the data is displayed correctly. Is this a bug or a limitation of mysql? Or am I doing something wrong? Any advice/help would be most appreciated.

Re: MySQL on windows
my experience is rather limited since i use linux only as a file server. after installations of mysql on win2k and nt4.0 sp6, i can say that it came up without incident, and has been running for months in the corereader test environment. it was far far easier to install than oracle, and easier to install than mssql. when i reboot the windows box, mysql has always popped back up. my philosophy with tools is if it doesn't keep running after i install it, i don't need it. so far, mysql seems to be a keeper. TERRIBLE! at least with ver mysql-3.23.53 on Win98. It crashes my machine after a while and when I close it, it sends the hadr drive into an infinite loop doing who knows what.

Character Based Front end for mysql
I have recently installed msql v 3.21 on my UNIX server (SCO Openserver Enterprise). Can someone steer me to where I might find a UNIX character based front end (NOT GUI) so that I might be able to interactively add, edit, delete, and browse the records of my database.

question about Sum()
Query: SELECT Count(id) AS Taken FROM ClassGuests WHERE id=5 Returns 1 record, value 0 Query: SELECT Sum(nGuests) AS Taken FROM ClassGuests WHERE id=5 Returns 1 record, value '' (nothing) And Query: SELECT Count(id)+Sum(nGuests) AS Taken FROM ClassGuests WHERE id=5 Returns 1 record, value '' (nothing) I expected to be 0, but it's not. And because of that I need to convert this through code. Is that anyway to force Sum() to return 0 if nothing found? Thanks.

RE: MySQL on windows
I've been running MySQL on Windows 2000 and Windows XP as local services on my DESKTOP, (I know, I know) without any problems. In fact, I hardly even know that the services are running except when I process a large chunk of data...

If so, you're probably not getting '' back, but NULL. And if *that's* so, you can detect that by checking for whatever value your API uses to represent NULL. - 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?

needing help with files
Greets: I just have a quick question. I've been setting up a website using a MySQL database loaded with a large number of articles but I'm having a problem. Some of the articles did not load correctly into the database. Is there a method of loading a text (well, in this case a *.html file) file directly into a field within a column? Any ideas?
