The SQL format - in decreasing order of unit size - is of course the most logical way because you can guarantee to sort on it and do other calculations. Over here in Europe we at least use dd/mm/ (increasing unit size order), which is the next most logical, but to start with the middle-sized unit, put the smallest unit in the middle and end with the largest is just... weird! -- Cheers...

Re: Can Innodb reuse the deleted rows disk space?
Hi, Try using the optimize table tablename ,but this will keep the data accordingly,but really if it is a disk space constraint you can go with re-org process in which you will have to get a down time for mysql db.Process is something like . Dump all the Innodb tables drop the existing innodb tables and shutdown mysql, clear the Innodb log-space as ibdata1 indata2 iblogfile0 iblogfile1 and also the redo logs of the innodb. Then start the mysql this will create innodb logs 1 innodb2 as what u have mentioned in ur cnf file and import the dump . In this case u can able to reduce the space usage of innodb. Try this it might help u out. With Regards Dilipkumar [EMAIL PROTECTED]: Hi, all I know the Innodb use MVCC to achieve very high concurrency. Can Innodb reuse the deleted rows disk space? I have an database which have many update operation. If Innodb can\'t reuse the space of deleted rows, I worry about that MySQL will exhaust our disk space very quickly.

Hi Chris, John all! Chris' explanation is nearly correct: Chris Sansom wrote: At 15:43 +0100 23/7/06, John Berman wrote: I have a table called: submissions and each record has an approvedate field which stores the date mm/dd/ Why? If you're storing the date in this format [[...]] John, you should ensure to differ between storage format and presentation format(s): - For storage, ensure that it can be sorted on (order year, month, day). Typically, this is achieved by telling the database a proper type (like DATE or DATETIME) and then just supplying a value. - For presentation, use what suits the users' taste. This may be configurable or depending on context (like drop the year if it is obvious etc.), and you can achieve all (?) desired results by the DATE_FORMAT() function. There should be only one storage format, but there may be many different ways to present a date. If you do not use the proper SQL type (DATE, DATETIME, ...), you cannot rely on SQL doing the desired operations (sorting, calculations, ...). [[...]] The SQL format - in decreasing order of unit size - is of course the most logical way because you can guarantee to sort on it and do other calculations. [[...]] That is correct except for the designation SQL: It really is an ISO format. The important property is having the most significant value (year) in the first (leftmost) place.

Select Query taking time
Hello All, I run a select query to see its speed. It took around 5 seconds. Now i run the same query simultaneously twice usng two instances of the client tool. It took 10 seconds for both the queris to complete. Its not 5 secs + 5 secs. Both the queries were running till 10 secs when i saw using mytop. In the 11th sec both the queries ended. Running it thrice simultaneously, it took 15 secs for all the three queries to complete. In such a case should this query be considered as slow? We are actually checking for queries which take longer than 12 secs and regarding such queries as slow. The moment we find such a query, a mail is sent to the DBA saying that the query is slow. So in a day there are more than 400 such slow query notifications flowing into the mail box. My questions are, Should the simultaneous queries take so long? Should'nt both queries have finished by 6 secs rather than 10 secs? Is this a right strategy to track slow queries? Any suggestions would help. Thanks, Ratheesh K J

Running it again immediately should be instantaneous, as the result set is in memory (and if it isn't, it should be in the OS disk cache [assuming a small result set]). Two queries executed simultaneously will cause disk contention, because the query isn't cached by mysql, and the OS cache probably hasn't had time to commit the data coming from the disks either. In the case of a single disk serving up the data, two simultaneous queries for the same data will cause the disk to go back and forth trying to satisfy each query.

Without query caching enabled, yes it is perfectly normal that the time spent is rising in a linear fashion, eg 4 simulatious would be 20 seconds, 5 25 secs and so on - this just means that your query run by itself is able to utilize all available resources such as cpu time. Look at it this way: 1 query will use 100% of the available cpu and it takes 5 seconds. When you run two at the same time they each have 50% cpu to use, and thus take 10 seconds (5 seconds * 100 / 50). With 3 they each have 33,1/3% and take 15 seconds ( 5 seconds * 100 / 33,1/3) and so on. Is this a right strategy to track slow queries? Yes and no. It is always wise to test your queries to see how the do speed wise, but if you only measure time you aren't really getting the full picture. You have to also look at what else the system is doing - if a query is bottlenecked only by available cpu, it will run at very different speeds depending on how busy the system is with other things - try to bzip2 a 500MB file while running the query and see how much time it takes then for instance ;) And as always remember to use explain to see how mysql optimizes your query so you can modify it if needed, especially complicated joins can sometimes be alot faster if you tweak them a bit.

Re: Struggling with the logic
As mentioned before you really should sue the date data type in mysql,
or alternativly use an int and store the date as seconds since the epox,
so that you can do simple math for this type of query. Any other way of
storing dates is basically shooting yourself in the foot.
That said, if you choose to store it as a varchar use:
Select * from submissions where approvedate in ('07/01/2006',
'07/02/2006', '07/03/2006',...);
Be aware how extremely slow this performs compared to the options
mentioned above tho.

Select * from submissions were approvedate - this is were im getting stuck
Pointers appreciated, im sure its simple ?

RE: Replication Problem
Hi Brett, Just about to go when your email rocked up 8-) Like you, I can't see any reason why it is not replicating according to the logs. Have you tried to create a database on the master and see if it appears on the slave? What commands are being replicated at this time? You can use the mysqlbinlog command to check the binary log to see what it is trying to replicate. There are certain commands that are not replicated and we want to eliminate those from the equation. Try the create database command eg. On master CREATE DATABASE THING; On Slave SHOW DATABASES; You should see the database thing on your slave. You can then drop the database on the master and it should disappear.

Will UPDATE block on SELECT?
I would like to know whether a SELECT query would block an Update on the same table. The table is of InnoDB type. Since InnoDB tables apply row level locks should the Update queries be blocked until the select query completes? I experienced such a scenario wherein an update query had to wait until the select query completed. Also how different is the locking when there is a CREATE TEMPORARY TABLE tblname AS SELECT * FROM TBL_TEST and an Update on the table TBL_TEST simultaneously? Pls Note: We are not using transactions. Currently all our tables have been converted to InnoDB type. Very soon we are planning to use transactions. Thanks, Ratheesh K J

MySQLHotCopy
I read in the manual that MySQLHotCopy would be better than MySQLDump for backing up MyISAM tables. However, I cannot find a .exe in the bin directory by that name. I found a script by that name in a 4.1 installation that I have, but I don't think it's the latest version. Is this a script? If so, does anyone know where can I get the latest copy? I've checked MySQL.com, but can't seem to find it there.

Hi, I've recently changed MySQL versions and I am puzzled by the difference in display of float values. CREATE TABLE test ( id int unsigned NOT NULL auto_increment, val1 float default NULL, val2 float(3,3) default NULL, val3 float(5,3) default NULL, val4 float(10,6) default NULL, PRIMARY KEY (id) ) TYPE=MyISAM; INSERT INTO test VALUES (1,36705.586,36705.586,36705.586,36705.586); select version(); select * from test; drop table test; === OUTPUT 1 mysql select version(); +-+ | version() | +-+ | 4.0.16-standard | +-+ 1 row in set (0.00 sec) mysql mysql select * from test; ++-+---+---+--+ | id | val1| val2 | val3 | val4 | ++-+---+---+--+ | 1 | 36705.6 | 36705.586 | 36705.586 | 36705.585938 | ++-+---+---+--+ 1 row in set (0.00 sec) === OUTPUT 2 mysql select version(); +---+ | version() | +---+ | 4.1.13| +---+ 1 row in set (0.00 sec) mysql mysql select * from test; ++-+---++--+ | id | val1| val2 | val3 | val4 | ++-+---++--+ | 1 | 36705.6 | 9.999 | 99.999 | 1.00 | ++-+---++--+ 1 row in set (0.00 sec) How is it possible that the two versions behave so differently?

mysqldump large file (2GBs) : some tests
Hello This is kind of a follow up of the previous thread Got errno 27 on write. file too large and kind of a survey. The problem was : on a solaris 9, 64 bits and mysql 4.1.7, I could not mysqldump in a file more than 2G . Thank you to the people that help me. I make a new thread since my question is different: is there anybody using that version of mysql (more or less) and that version of Solaris and be able to mysqldump more than 2GBs. If so I would appreciate to have more details on revision etc. ? Here is why I am asking this question: Since it appears it was the revision on my server that might be the problem, but because the upgrade could not be done in short term and because Sun Support did not find any problem of that sort on the system, I decide to forget about the mysqldump for now and copy files for backup. But then I wondered if, later on, as my datafiles increase in size, I will have the problem with the 2 gbs limitation for the datafiles themselves . Which would be much worse. But I succeded in dumping 4gbs in one table. Good news! Then I wonder if my OS allows to do that, how come it does not work for mysqldump. Thank you in advance Johanne Duhaime [EMAIL PROTECTED]
RE: Replication Problem
Hi Brett, I am a little bit lost as to why this is happening. The only suggestion I have at this point is to go through the replication troubleshooting in this chapter and see if something there is causing the problem.

Brett Just about to go when your email rocked up 8-) Like you, I can't see any reason why it is not replicating according to the logs. Have you tried to create a database on the master and see if it appears on the slave? What commands are being replicated at this time? You can use the mysqlbinlog command to check the binary log to see what it is trying to replicate. There are certain commands that are not replicated and we want to eliminate those from the equation. Try the create database command eg. On master CREATE DATABASE THING; On Slave SHOW DATABASES; You should see the database thing on your slave. You can then drop the database on the master and it should disappear.

mysql_stmt_bind_param error
I tried to execute the example code (see below) from the function
mysql_stmt_execute I found in mysql 4.1 documentation
(http://dev.mysql.com/doc/refman/4.1/en/mysql-stmt-execute.html). This
source code runs perfect under linux red hat with version 4.1.7 but it
prints out an error if I try to run it under windows XP SP2.
This is the output of this code
prepare, INSERT successful
total parameters in INSERT: 3
mysql_stmt_bind_param() failed
Using unsupported buffer type: 838860800 (parameter: 2)
It seems that the function mysql_stmt_bind_param is not working under
this environment.
I tried installing version 4.1.20 and linking my program with the new
library but the result is the same.
Is that a bug of windows version? Can anyone help?
Thanks in advanced

If things worked before, check if any updates to glibc were done. Otherwise I'd just google around a bit for AIX+mmap64 and see what comes up. Previous version which did compile was 4.1.9. May be glibc was not required for this version. Glibc is not native to AIX so I can see some fun ahead. First: The binaries built and distributed by MySQL for AIX are done using the IBM C compiler, not gcc, so we at MySQL do not encounter this problem - that's why I can only speculate. I know that gcc on AIX uses the header files provided by IBM, but modifies them when gcc is installed - a vague memory says the tool for this is called fixincludes. Try to search for this, there are good chances in the archives of comp.unix.aix (or via Google Groups). AFAIR, gcc on AIX does not link to glibc but to IBM's libc, that's why the system headers must be used. According to the error message, the system-provided header file /usr/include/sys/mman.h is now inconsistent between lines 110 and 115 - this might be a problem caused by fixincludes. Can you check the file and see what is happening there, maybe post the lines here or on comp.unix.aix ? The warning about Z_ASCII being redefined seems to be less critical, but you should check that also to be sure. I propose you look at the two conflicting definitions of Z_ASCII and compare them. If you have sources for the zlib and can compile them using gcc, this might be a way out (after you solved the conflict of the definitions). If you do not need the archive table handler, you might also exclude that from the configuration and try without it - bypassing the problem, not solving it. Regarding the successful build of 4.1.9: Most likely it did not need the header file(s) in question, so the inconsistency did not matter. Also, if you upgraded gcc in the meantime, this might also be a reason. I hope you get it solved! Regards, Joerg PS: Curious: 1) What is your reason to compile yourself ? 2) I assume using IBM C is no alternative, because you do not have it ? 3) Remember that 5.1.6 does not have production quality, and please check the changelogs so that you do not get stuck on a later change. -- Joerg Bruehe, Senior Production Engineer MySQL AB, www.mysql.com -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
replicated queries are not placed in the binary log of dual master replication set up
Hi, I'm building a dual master set up that looks something like this: master A - master B || slave A slave B Replication between the masters works. Replication between the slaves and their respective masters works (ie, inserts on master A are replicated to slave A, and inserts on master B are replicated to slave B). However, queries that are run on master A, do *not* make it all the way to slave B. The queries execute on master B but I have verified that they are not being written to master B's binary log. Hence, slave B is not seeing the updates. I can't find any extra configuration options in the docs that shed light on this issue. Have I missed something, or have I found a bug? I'm running mysql-5.0.22 on Solaris. Thanks!
mysql + LVS
How stable has it become to run an instance of mysql ontop of a LVS cluster to produce a massively parrallel system to be used for huge databases? Back in the day i remember tyring to do it with mosix, not sure where they are now a days. but either way i am looking for some current information on the subject.

Hello, Just to make sure we separate the two... mysql cluster that preforms reads on all the slaves, and writes only on the master.

Granting all to a user with a db name prefix
Hello All, I'm trying to GRANT ALL to a user only on DBs that math a prefix, but i can't find the way to so it on the documentation. Let's assume the username is john. I want him to have all privileges only on databases with the prefix john, so he can: - create and drop databases starting ONLY with john (like john_sessions, john123, john_mytest, john_mail, etc) - have any kind of privileges on such databases According to the documentation, i can use % and _ as wildcards. However, mysql gives my an error if i try to use % wildcard. Only _ wildcard is accepted, but the following example: GRANT ALL ON JOHN_.* to 'JOHN'@'%' IDENTIFIED BY 'foo'; ..only allows user john to create databases starting with john, followed by ONE single character. Using this, i can give 32 different grants in order to allow up to 32 characters after 'john', but i'm sure that's not the way. If i try the wildcard %, i get an error. I've tried the following: GRANT ALL ON JOHN%.* to 'JOHN'@'%' IDENTIFIED BY 'foo'; GRANT ALL ON 'JOHN%'.* to 'JOHN'@'%' IDENTIFIED BY 'foo'; GRANT ALL ON JOHN%.* to 'JOHN'@'%' IDENTIFIED BY 'foo'; GRANT ALL ON 'JOHN%'.'*' to 'JOHN'@'%' IDENTIFIED BY 'foo'; GRANT ALL ON JOHN*.* to 'JOHN'@'%' IDENTIFIED BY 'foo'; GRANT ALL ON 'JOHN*'.* to 'JOHN'@'%' IDENTIFIED BY 'foo'; ..and almost all similar ways. Am i missing something? I temporarily fixed the problem by directly editing mysql.db to change the wildcard _ for % in the respective record, and it works fine. However, i really want to know the right way to do it. I hope someone there gives me the answer. Thanks a lot, have fun.
