Re: sort order
Hi Wes, have you double checked you character set and collation ??

The collation is which determines the sorting order.

Re: BLOB data gets encoded as utf8! (Anyone?)
I think that probably the mistake is in the way you are inserting the
blob.
If i understand right, you are inserting the blob with a traditional
insert statement ??, in my experience i always use prepared statements
to insert blobs, in that way the text goes exactly as the source without
any utf-8 conversion.
Besides this, using the insert can truncate your blob / statement,
because some drivers/connectors limit the size of the sql statement, so
if you are uploading a huge file the statement will not work (I dont
know if this happens with the mysql driver or if there is a limit), so i
strongly recommend using prepared statements for blobs with any database.
Hope this helps.

Subject: BLOB data gets encoded as utf8!
Hello everyone!
I am using an MFC unicode project that uses ODBC to access a MySQL
5.1.50 database via the MySQL ODBC 5.1.6 driver.
character_set_connection is set to utf8 (Which I believe is the default
for the driver) One of the tables contains two LONGBLOB columns, and the
table default charset is utf-8 (since the application is unicode).
However, when inserting into the LONGBLOB columns via an INSERT
statement, the data gets corrupted/modified because is incorrectly UTF-8
encoded.
My insert statement (simplified) does this:
INSERT INTO _table_ (Desc, Data) VALUES ('...', '_blobdata_');
I have also tried the _binary introducer
(http://dev.mysql.com/doc/refman/5.1/en/string-syntax.html)
INSERT INTO _table_ (Desc, Data) VALUES ('...', _binary'_blobdata_');
I'm escaping 0x00, 0x22, 0x27, and 0x5C, which are the only four that
MySQL requires to be escaped per documentation for BLOB fields, and
according to the MySQL docs columns of any BLOB type use no character
set.
Here is the problem: I found that, for example, 0xFF gets modified to
0xC3BF, which is in fact the UTF8 encoding for ASCII/Binary 0xFF.
Needless to say the data becomes useless. I did, however, determine that
the data is already corrupted in the myodbc.log file that the driver
outputs if the option is set, so there is likely a problem with the
driver settings or with the statement itself.
I cannot be the first one to encounter this issue, so maybe if you have
an idea (or a solution would be even better! :) then please let me know.

Re: Innodb buffer pool usage
Hi Machiel, What do you mean with innodb buffer pool is at 100% full ? There are several status variables associated with innodb buffer pool ie: Innodb_buffer_pool_pages_free is the number of unused data pages. Innodb_buffer_pool_pages_total is the total number of pages. Innodb_buffer_pool_pages_data is the total number of used data pages (clean and dirty). Innodb_buffer_pool_pages_dirty is the number of dirty data pages. The number of clean data pages can be calculated from these first two status variables. etc.. You can calculate the usage ratio with a basic recipe: Innodb_buffer_pool_pages_free / Innodb_buffer_pool_pages_total This is the value that you have to monitor. If its close to 1, then you set up too much memory for innodb (warning: that this can be due to frequent flushed to disk, so you have to check that too); if on the other hand the ratio is too low, then you effectively are running out of resources and may need to add more memory to innodb. You can imply other things, with the other variables too. Obviously you have to do the job and review this values along the time, maybe there are some actions/effects like running reports or etl processes, you have to figure out what is going on as a whole not just the values in the formula. BTW: In Oracle is the same story, one thing is what you reserve for...and other thing is the actual usage. The latter if you are tuning Oracle manually, because one important difference in Oracle 10 and 11 is that the buffers can grow and shrink automatically (if you configure it) so you can say use the 100% memory at your convenience and Oracle can, for example, reduce the sort buffers and extend the index buffers on the fly. Obviously this also has advantages and disadvantages, but as a new DBA is good to get involved in this concepts and comparisons between dbms.

Someone replied and stated that this is preferred to be running at 100% usage as it means that it is running optimally. However, the oracle guys in our office disagrees with this and want to know the following: . If the innodb buffer pool is at 100% full, how will we know when it needs more buffers o i.e. let's say the database starts getting very busy and needs more buffers, how will we know that it requires this if the buffer pool usage is already at 100%.

Re: How to change mysql default database directory
As Suresh and others said, you have to stop the dbms, move to content of the dir and restart the dbms. Also, if you have a fresh install, innodb tables will be saved on a datafile inside the same data dir, but if is not a fresh install you may have innodb variables (ie. innodb_data_home_dir) in the config file, and you may need to change those too.

One of the features is we need to record and ensure that the user password is different from any of the last four passwords he/she has used. I was thinking of create four fields called Password1, Password2, Password3 and Password4 to record the old passwords. Is this a preferred method - or does anyone else have any recommendations ? Thanks, Neil I'm not an awesome database designer, most of what I do is code related stuff, I think what I would do for this is 1. hash the password( sha256/512 whatever) and then 2. store the hash in a string with delimiters. In that way, you solve 2 problems. You can store as many as you want to because you can just check hashes to make sure it isn't the same, and second, you aren't storing passwords in plain- text, which is a personal pet peeve. Neil, As others appointed, having another table with old passwords is a good design solution, and can allow you to have more than 4 passwords on your history. But in fact your solution is the best solution for performance and is called denormalization, this solution gives good performance because in 1 read you get all the passwords but has the limitation of be fixed to only 4 passwords (which is not so bad because you can add new columns as needed, you will never have 20 history passwords anyway, do you ?). So, thats the trade, design vs performance, you should pick the best for you. The solution proposed by Colin is another way to do it but, from the good design perspective is NOT a good solution, is what its called a multivalued attribute and all those should be avoided. But again, is up to you. Carlos -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/mysql?unsub=arch...@jab.org

Check how many root rows do you have on the user table (select * from
user where user='root';), some times there are several rows with
different grants and probably you are going through and invalid rule.

Re: error in login
Hola Hector, el problema son las 2 tuplas que mencionas, ya que debido a su jerarquia pueden hacer un conflicto que te evita conectarte correctamente, en tu caso si deseas que el usuario se conecte desde donde sea (%) elimina la tupla de la tabla user donde aparezca el localhost, esto puede ser en la table user o en la tabla db de la base de datos mysql. Hector, the problem is maybe that you have 2 rows granting permissions to this user and is possible that due to hierarchies or precedence one overrides each other. I suggest to eliminate the localhost entry and leave the % because anyways you are allowing this user to connect from anywhere including the localhost.

Re: How do you allow external computers to access server instance?
Mysql restricts access outside the server after the installation (on not
all, but several cases) so i suggest to connect to the mysql database as
root and review the host values on the user table, that can give you an
idea of who is allowed and from where is allowed ...remeber that % means
anywhere.
If you need more information i suggest to read the manual searching by
users permissions.

My first impression es that your insert is wrong, because inserts cant

completely new insert including the column1 or maybe you want an

Re: Growing innodb size
You need to close the size of ibdata1 and add the second file ibdata2 with the size you need (and i you like you can even add the autoextend option, but only to the last ibdata file added) for example, if you are aproaching the 1gb size on ibdata1, you specify the maximun size that you want for that file and then add the second file: innodb_data_file_path = ibdata1:988M;ibdata2:10G:autoextend For further information check: http://dev.mysql.com/doc/refman/5.0/en/adding-and-removing.html Carlos Jean-Sebastien Pilon wrote: The following does not work, it gives a syntax error. innodb_data_file_path = ibdata1:10M:autoextend;ibdata2:10240M I tried this instead and it didn't want to start and mysql crashes, is it because it expects the data to be located in the 1st datafile ? innodb_data_file_path = ibdata2:10240M;ibdata1:10M:autoextend Then I tried with the following option in my.cnf as suggested on mysql website innodb_force_recovery = 4 It still crashes Works good when I put only the following innodb_data_file_path = ibdata1:10M:autoextend Any idea someone ? -Original Message- From: Jean-Sebastien Pilon [mailto:[EMAIL PROTECTED] Sent: Wednesday, February 21, 2007 12:53 PM To: Nils Meyer; mysql@lists.mysql.com Subject: RE: Growing innodb size +---++ | Variable_name | Value | +---++ | innodb_data_file_path | ibdata1:10M:autoextend | | innodb_data_home_dir | /var/lib/mysql/| +---++ There is one defined, since I have innodb tables in there, very small ones.

Re: Error: Duplicate entry 'xxxx-L' for key 6
i think you are in fact duplicating an entry on the index, probably one of
your indexes on that table is length restricted and that cause that 2 fields
that as a whole are different, they are not to the index length.
My two cents.

Hi,
While we were using old hosting company (15 days ago) on php
4.3.4/mysql
4.x based Linux server, the application I wrote to upload new
products i
MySQL was working fine.
After we moved now I'm getting strange error I can't explain.
I think it's
caused by moving to mysql 5.
For example: in the application csv file is uploaded to the
server, then
it reads product no. from product row and search if such
exosts in DB. If
yes, add prod. number to message that will list all products
that admin
tried to upload but they already exists.
But, I'll sometimes get the error message, e.g.:
Duplicate entry 'Lavander Peak Purse-L' fo r key 6
The thing I don't understand is 'Lavander Peak Purse'
(without -L) is
product name and it's not index nor unique?!? And there is
no such a
product in DB?!?
Why is '-L' added to the products? What does it mean? What's key 6?
I tried to find answer on mysql.com but only think I found is

Re: Question Concerning (innodb_buffer_pool_size)
Yes of course you can and...you should As the my.cnf says # InnoDB, unlike MyISAM, uses a buffer pool to cache both indexes and # row data. The bigger you set this the less disk I/O is needed to # access data in tables. On a dedicated database server you may set this # parameter up to 80% of the machine physical memory size. Do not set it # too large, though, because competition of the physical memory may # cause paging in the operating system. Note that on 32bit systems you # might be limited to 2-3.5G of user level memory per process, so do not # set it too high. So if you are using innodb as you main engine i suggest the advice of 80% of ram, obviously it depends of the current load in the server; if you are running ie. an application server you would have to divide the ram according to each needs.

Re: Adding index -- Need help
Remember that if you dont use an index on a colum and you search by that criteria, there would be a whole table scan :(. Its recommended that you always index those columns that appear on a search and/or an order (where column_a='yyy' order by column_b) and those involved on joins; generally speaking joins are always based on primary keys, so, if you have already defined the primary keys there is an index associated with the columns of that primary key (just remember that order matters), so the join use the index and not the whole table.

RE: Lucene with MYSQL
Hi, i have been using Lucene MySQL but separately, MySQL is written in C/C++ with a JDBC driver available and Lucene is coded in Java, so (besides the mysql team opinion) you can mix searches throught both apis and referring to each other with the PrimaryKey. This combination works fine for some scenarios but it doesnt for others, in some cases the best choice is to use the FullText feature available in MySQL which employs the same Vectorial Model that Lucene's do. One advantage of Lucene is that is composed of layers and you can modify it to use different models instead of uniquely the Vectorial; on the other hand Lucene doesnt support concurrency which can be a serious problem in your application or maybe not.

Could you just briefly explain layers and concurrency maybe w/a simple real-life example so I can see the contrast between the two searchs? Thanks very much, Lee G. Sure, i mean layers relating about java packages, Lucene have different packages to store, index, retrieve, apply IR model, etc, so for example if you want to use a different index schema you can modify that package and improve or customize that layer, the same applies to IR models, most models are based on frequency, collection size, etc those methods are available so you can build an entirely new algorithm (ie. Latent Semantic) with the core indexing of Lucene. About concurrency, MySQL is a engine that supports thousand connections at the same time and mantains some indexes in memory (even Full Text indexes i think, someone at MySQL can confirm this ?) so every operation is very fast; Lucene is not an engine its an API, so every add/update must check if the index file is locked, wait and so on. If you need something more robust in this way MySQL is the best choice; if you are thinking in something more static than doesnt update frequently then Lucene can be a good one. Lucene's faq and http://today.java.net/pub/a/today/2003/07/30/LuceneIntro.html are good references for more details. regards Carlos Proal Hope my 5 cents works to you :) Carlos Proal Original Message Follows From: leegold [EMAIL PROTECTED] To: [EMAIL PROTECTED] Subject: Lucene with MYSQL Date: Thu, 29 Jul 2004 13:36:56 -0400 Is it possible to use the Lucene fulltext search on a MYSQL database - say for text type fields? _ MSN 8 helps eliminate e-mail viruses.

RE: MySQL Dump Command Does Not Consider Foreign Key Dependencies
i turn off the checks before a dump in order to restore it properly.
In my scripts looks like:
echo SET FOREIGN_KEY_CHECKS=0;
${mysql_backup_directory}/${2}/${database_filename}
mysqldump --opt -h $2 -P $3 -u $db_username --password=$db_password $1
${mysql_backup_directory}/${2}/${database_filename} 2 $logfile
}
I would suggest that this can be included as a mysqldump option (--nochecks
or similar).

Subject: MySQL Dump Command Does Not Consider Foreign Key Dependencies
Date: Fri, 05 Mar 2004 13:06:09 -0500
Description:
The current mysqldump utility does an alphabetical dump of the
tables as well as a row by row dump of the data following each
table declaration. This is adequate enough for most
databases; however, if there are strict foreign key
constraints, the ordering will not always be conducive to
utilizing mysqldump output to restore databases causing major
headaches in order to restore when the table structures are
sophisticated and/or if there is considerable BLOB output in
the output.
How-To-Repeat:
I apologize for any syntactical mistakes, but I'm sure you can
get the idea. Consider two tables: a,b. After creating
these tables, defining several columns, and then implementing
foreign keys, if a has a
foreign key constraint on yet-to-be-created b in dump output,
then a will fail to create. Further, even if a were to be
created, data input into a would fail without the supporting
rows in b.
Fix:
Ultimately, a dependency graph needs to be considered before
dumping in order to dump the tables and data in an order that
will allow the output to be used to restore the data rather
than alphabetical. However, if we assume that the data
existing now is in a normal state (simplified to mean,
fulfills foreign key constraints), then we could dump
structure and data in same order, but suppress details about
the foreign key constraints and have those appended to the
dump output as ALTER TABLE statements. I believe the latter
to be a much simpler fix and would eliminate this problem.

Hi all, mysql-team i have a very very complicated problem , hope to be clear. i have a file report (.txt) with about 200,000 data about books (title, clasif, year, publisher, authors, subjects, etc etc) without tabs or separation, i built a parser to split each field and works fine. After each sequential parsing (one book) i upload that info to the database but in 5 tables (verifying duplication, ids, etc): book author subject book-author (relationship) book-subject (relationship) When i reach the book number 11500 (aprox) mysql shows a deepth fall in performance , each insertion takes 30 segs or more, even with/without indexes. First i though that parsing takes longer, so i parsed the entire file and generated a java serialized file, then just inserted to db but was unsuccessfully , still the same performance. I have calculated the total number of rows for each table and is about 200,000 for books, 150,000 for authors , 130,000 for subjects and relations can have 250,000 each one. Any have an idea of how can i upload this information quickly ??? I'll really appreciate any advise.

Yeah indeed, imagine an old bibliographical card, well i have a file with
200,000 consecutive cards.
After each sequential parsing (one book)
What defines one book? One file, several records from one or more files, or
one record from a single file?
I have a file something similar to:
---
Classification: QAT67.0
Title: History of America System key: tyup
Authors: Broom, Rodney. Proal, Carlos
Subjects: History, Social Sciences
...other fields
Classification: QE56.0
Title: Mysql System key: iuds
Authors: Broom, Rodney. Dubois, Paul
Subjects: Computer Science, History
...other fields
...200,000 records like these
After each parsing (just reading one record) i have a java object
containing:
Book information: title, classif, systemkey, etc
Book's authors: array of [author1,author2]
Book's subjects: array of [subject1,subject2]
i upload that info to the database
You upload? How is this done, exactly? Do you mean that you run mysql from
one machine with the host set for another machine?
when i begin the whole process i open a connection to the DB by java
using localhost (i work on the same machine).
...but in 5 tables...
So you've split your data into sets that need to get loaded into five
destination tables, or you upload five sets of data?
the first one, i need to split into five tables.
(verifying duplication, ids, etc):
Does this mean that you are checking for duplicates before loading into
MySQL?
yep
let me explain, i have a kind of do-while statement like these:
open connection to db
while (still records in the file)
{
parse one record
insert book information into table book (classif, title, year,
etc)
for(each author (current book))
{
if author currently in db (through a select)
get authorID
else
authorID= insert author into table author (id
authorname)
insert into table book_author (authorID, classif) -
relationship
}
...subjects with similar for that authors
}
close connection to db
thanx again

Hi Carlos,
I'm glad to help, but I'd like to clarify several things, first.
thanx a lot ;)
...with about 200,000 data about books
(title, clasif, year, publisher, authors, subjects, etc etc)

Hardware advise
Hi all, i need to deploy a huge database (about 160 Gb) of information, mainly images and pdf documents, access will be aprox of 25 simultaneous connections in the worst case; so i need to choose the right hardware configuration and i need your help. We are thinking in a Sun Ultra 10 with 128 or 256 Mb Ram, but i have no idea about storage, i saw a Seagate hard drive of 181Gb. Ultra160 SCSI ( $ 2000 usd) but i dont know if this is the best option because i have heard about raids and racks but never used it. Any experienced DBA could give tips about the whole configuration ?? thanx in advance.

multiple databases performance
Hi all, glad to be back in the list :) I have a question related with a huge project, i could have these 2 schemes: 1) just one database with several tables database | tables DB_1 | user, profile, supplier, dept, etc... a lot of tables 2) several databases with few tables database | tables DB_1| user, profile DB_2| supplier, dept DB_etc | etc what would be the best choice ?, think that all tables contain thousands of rows, and applications have to access most of them, for example user information; even when working with suppliers users are required, so in case 2 the application must connect to both databases. any suggestions ?? thanx a lot.
