Database recovery
Hi, I have recently had a system crash that required the installation of a new hard drive. I have access to the files on the old hard drive, on which is a database I need to recover. I am running MySql 3.23.37 and all the tables in the database to be recovered are MyISAM. How can I recover the old database onto a new server with only file access? The documentation suggests to me that I need to copy all the *.frm, *.MYD, and *.MYI files. If this is the case, where should I copy them to on the new server? The technical director is away and I am in charge of this recovery... I dont want to get it wrong, so *any* help is greatly appreciated. Andy Hall.

Re: Mysql Linux can't auto flush-tables
TTBMK, there is no such thing as 'auto flush' in MySQL. When you say Everytime I add some record on my local computer then upload ... are you saying you upload the raw database files (from your data directory), or are you inserting/updating the data in your Linux databases with a query? If you are uploading the raw files, that is not a good practice. If you are updating/inserting it with a query, you shouldn't need to flush tables anyway. G.

join problem: indexed columns being ignored
Afternoon all. I wonder if any experts on the join optimiser could help me
out. I have read the docs, including the material on how mysql optimises
joins, and have redesigned my schema somewhat to try and simplify the joins,
and that has worked to some extent. But I am still way off the performance I
should be getting on my problem queries.
My Question: Why don't my queries use the entire index I have created on the
spam(t1) table? Is there any way to force mysql to use my index as I intend?
What factors influence the choice of index/column in this case?
Basics first: I am using MySQL 4.0.18 (mysql.com official build) on a Dell
1750 dual Xeon running slackware 9.1, kernel 2.6.3, loads of memory, loads
of disk space. My my.cnf is pasted in at the end. All tables in this query
are innodb.
My problem: I have 2 problem queries which involve a join on 3 tables. I
have created an index on each table, and all columns required for the join
are indexed. All boolean operations are AND. All conditions are x=y or
x=const. On 2 of the tables, only 1 column is used - no problem there; on
the 'problem' table (spam(t1)) 3 columns are used, and I have created a
multi-column index (SP_RID_STA) which includes all 3 relevant columns. The
problem: according to 'EXPLAIN' mysql is not using the entire index. I have
two sample queries below; the first counts the items in the table, and uses
2/3 columns), and and the second selects the first 10 items (uses 2/3
colums). I am judging the index usage by the 'key_len' value in the explain
output. The first column should be '1', the second '8' and the third '1'. I
am therefore expecting '10' in the key_len result for both queries.
Currently the script which runs these queries times out. I need it really to
take of the order of a couple of seconds. I don't see why this should not be
possible with the right indexes, judging by what I have been abloe to
achieve with similar scripts on the same data.
Thanks in advance
Jim

I think the problem is here: and (workorders.closedby = personnel.id OR workorders.closedby IS NULL) There is no way for a personnel record to be selected if the closedby value is NULL, so no record gets selected. The simplest way to fix this is to add a 'null' personnel record with personnel.id set to NULL. Then remove the 'OR' phrase, and it should work, the null record being selected from personnel when closedby is NULL.

Re: MySQL on Linux
I ran into the same issues on RH8, with a default implmentation. It can be overcome, but the mysql failed to write to the table after 2gb or so. It turned out to be a filesystem limitation issue, which was fixable. I am not sure, but given the size of files nowadays, RH9 defaults probably take care of it. I am currently running several very large tables on RH8 (5-30G) and it is stable. One should always beware that large tables can easily be corrupted, and are not a joy to recover though :-/ P Alan Williamson [EMAIL PROTECTED] 04/06/2004 05:57 PM To: Dan Nelson [EMAIL PROTECTED] cc: [EMAIL PROTECTED] Subject:Re: MySQL on Linux Thank you, a much reasoned and sensible reply.

This is not old hardware (12months old). That is because although Linux binaries can access files over 2gb, they do not do so by default.

Hello, MySQL gurus, I have been trying to output the result of some large query to a temporary table and then query from there.

Database design question
Hi, I'm writing a database for an online candle store. Here's the situation. This store sells all sorts of items including candles. Now the gist is that some of the candles can be made in different types of waxes and some only have one wax. My question is how do I resolve this when I write up the order and write up the line items. This almost seems like it is going to be some sort of a three way join or something.
Re: ERROR 2013 at line 7: Lost connection to MySQL server during query
What is your max packet size? Are you able to determine where the `error` occurs in the process? During the load of the temporary table? During the query of the temp table?

Re: MySQL on Linux
Well I guess it depends on what is meant by Default. I was using RH8 and had no such issues, even with RH7... I think it's important to note the filesystem chosen can make a huge difference. as of RH8 and onward I'd suggest EXT3, especially for Peter's issue of possible corruption - because it is a fully journalling filesystem. of course, a filesystem cannot (and will not) overcome issues with the software or OS itself. It's always best to use the latest stable Mysql (4.0.18 as of last I checked), and don't always upgrade just because. too many admins will upgrade just because the latest thing is out, if it's working, stable, etc, leave it alone. don't fix it if it aint broke. the point is, choosing the right options during install. myself, I never had an issue with the defaults, even back as far as RH7, using files larger than 2gigs with mysql. perhaps because I always choose the best file system available at the time. I chose journalling as soon as it was available, things like ReiserFS come to mind. for me, large files was always the default, never had to choose it manually or change any settings. oh well... Dan. On Wed, 7 Apr 2004, Peter J Milanese wrote: I ran into the same issues on RH8, with a default implmentation. It can be overcome, but the mysql failed to write to the table after 2gb or so. It turned out to be a filesystem limitation issue, which was fixable. I am not sure, but given the size of files nowadays, RH9 defaults probably take care of it. I am currently running several very large tables on RH8 (5-30G) and it is stable.

The easiest answer is just to have an extra column waxtype and have the ordering application only allow valid settings to be put in it, allowing NULL in the case where there is no choice of waxes. You seem to have discarded this option - but you haven't told us why, so we cannot tell what alternative to suggest.

Re: ERROR 2013 at line 7: Lost connection to MySQL server during query
Hi, The max packet site is 1048576. But I don't think it is a problem cuz I have successfully outputted the result of this query before. I checked mysqld.log. This is the tail I think might related to the problem: Number of processes running now: 0 040406 22:22:01 mysqld restarted Cannot initialize InnoDB as 'innodb_data_file_path' is not set. If you do not want to use transactional InnoDB tables, add a line skip-innodb to the [mysqld] section of init parameters in your my.cnf or my.ini. If you want to use InnoDB tables, add to the [mysqld] section, for example, innodb_data_file_path = ibdata1:10M:autoextend But to get good performance you should adjust for your hardware the InnoDB startup options listed in section 2 at http://www.innodb.com/ibman.html Does that mean it tried to create the tmp table as an innoDB table instead of MyISAM and I need to get innodb_data_file_path set to correct it?

RE: Using BYTEFX to connect to MySql , closing connection do not release the connection.
I'm not sure why this is happening, but the behavior you described in the first email is correct pooling behavior. By default, connection pooling is enabled which means connections are not killed when they are closed but remain open and able to serve new connections if necessary. Only when the app quits is the pool manager collected and the connections killed. If this is not desired, you can add pooling=false to your connection string. -reggie -Original Message- From: tweewan.wong [mailto:[EMAIL PROTECTED] Sent: Wednesday, April 07, 2004 6:44 AM To: [EMAIL PROTECTED] Subject: RE: Using BYTEFX to connect to MySql , closing connection do not release the connection.

Hey what, no pity for a new user?
A couple days ago, I posted a careful message of my troubles, but no reply to date. Remember, after I tried to assign a password for the root user, it broke. Since then, I discovered that Mac OS X refuses to let me create a user account called 'mysql'. Apparently that account comes preconfigured since the latest version (Panther). But since I had an account by that name before I installed Panther, but then deleted in a misguided attempt to fix my problems, I was in a boat. I created a new dummy account, then used NetInfoManager to rename everything. Then I used Terminal to rename the home directory, and SharePoints to add the new user to the mysql account and delete the dummy group. Then I used Terminal to change the group of all the stuff in the new home directory. So now it has quit complaining about the chown command, but it still quits immediately when I try to run mysqld_safe, as follows: [iMac-dv:/usr/local/mysql] kj% cd /usr/local/mysql [iMac-dv:/usr/local/mysql] kj% sudo bin/mysqld_safe Starting mysqld daemon with databases from /usr/local/mysql/data 040407 09:55:25 mysqld ended [iMac-dv:/usr/local/mysql] kj% I would be happy to just kill it and start over. -- Sincerely, Kevin Jaques (at home) Use [EMAIL PROTECTED] for work related messages Send lawyers, guns and money!

Re: Database design question
Everything I've read about creating online stores is that you are selling inventory items, not the items that makeup the inventory item. So if you sell a red candle made from wax X, candle is the product and red wax X are two attributes of the product. Ideally your structure would work for any product, which means no columns like waxtype or color. Off the top of my head I'm thinking a product table with things like name, description, price, etc. An attribute table. And a productattribute table to link the two. Your attribute table could be a multipurpose table from which you could group your attributes into categories (i.e. wax type, colors, etc.). Something like this: IDPrime IDCategory AttrName AttrDesc The IDCategory field would be a relation to the IDPrime field (a self join). If the IDCategory field is '0', you know it's a top level category. This gives you the ability to create a hierarchy with unlimited depth. The data might look like this: 1 0 Candles Burns bright for hours 2 1 Shape Shapes of candles 3 2 Round 4 2 Square 5 2 Pyramid 6 1 Color Colors available 7 6 Red 8 6 Blue 9 6 Gold 10 1 Wax Type 11 10 X 12 10 Y 13 10 Z You can add as many attributes as you like without having to ever change your database structure. So if they are buying a Candle, you search the attributes for Candles and get Shape, Color and Wax type (scent, logo, etc). The user then picks each attribute. If you code it right, you wouldn't even have to change you code when you add attributes and categories. You then store the user selection in the productattribute table. The Product table would be pre-populated with the products you offer, including their links to the attributes. But the design is flexible enough to allow a user to create a custom product or customize and existing one. The shopping cart then only contains the link to the product table. Obviously there is a lot more too creating the whole system, but hopefully this gives you some ideas.

Many thanks Alec. I need to wait a couple of hours before I can block access to the DB by messing with the indexes, but I will try out what you suggest. What you say makes sense as probably over 99% of the values in that first col will be 'y'. I will post my progress. I am also looking into recoding the where clause as inner joins ... I didn;t expect this to make any difference as I would have thought mysql figures this out but it _seems_ to cut down the query time to 2-3 secs without using any extra index columns ... bizarre.

Table lock problem on INSERT with FULLTEXT index?
Hi there, I've got a bizarre problem I can't seem to solve. I have a small MyISAM table (6533 rows) with a small FULLTEXT index (3 columns per row, an average of 1 word per column). When I do an INSERT on the table, many times the thread gets stuck perpetually in Query | update. Future reads from other threads, of course, stay Locked. When I try to kill the thread using mysqladmin, the thread sticks around for thousands of seconds in Killed | update until I finally just have to kill mysqld manually and let it restart. I've tried REPAIR, ANALYZE, and OPTIMIZE on the table, both using mysql and myisamchk. Tried all the options, such as extended and force and the like. I've even tried wrapping the INSERT with LOCK TABLE table WRITE and UNLOCK TABLES. Still no dice, the INSERT still hangs sometimes. I haven't bothered trying INSERT DELAYED since LOCK TABLE seems more drastic anyway and it didn't work. This happens both on 4.0.17 and 4.0.18. This is a RHEL3 WS dual AMD64 box w/8GB of RAM. Strangely enough, I have another MyISAM table with 1,285,742 rows and a larger FULLTEXT index, and it never locks this way. I have a third MyISAM table with 61,834 rows and a larger FULLTEXT index that locked on me once like this last night, but then I ran through and updated nearly every row overnight, and inserted a few hundred new ones, and it didn't lock at all. FWIW, it only seems to hang on INSERT, not on UPDATE. I haven't tried DELETE yet. I'm stumped. Any help would be greatly appreciated!

Re: Hey what, no pity for a new user?
I'm not sure if this is part of your problem or not Kevin,
seems you have a few issues, so I'll cover them one at at time...
getting the permissions and ownership correct, this is cut/paste from the
INSTALL docs, pretty much cut/pasteable to your sytem (errr):
groupadd mysql
useradd -g mysql mysql
cd {wherever mysql is installed}
scripts/mysql_install_db
chown -R root .
chown -R mysql data
chgrp -R mysql .
run mysql with:
bin/mysqld_safe --user=mysql
setting up the root user access:
I found a few times MySQL had issues with setting up the root user,
host access. This was in the past, and I've since found it seems ok,
but every now and then it bombs out. Never did figure out why. But
there is a solution to it.
if you read the docs as per installation, it talks about setting up
the new install, setting the root user password, and then allowing
the host access.
here's the root user password setup line:
bin/mysqladmin -u root password your_password
where your_password is the password you want.
and password is the actual word password - so many people get confused
about that. and this line:
bin/mysqladmin -u root -h `hostname` password password
for me, it was always the host access line that failed. but give this
a shot.
hopefully it helps a bit.
Dan.

RE: Database design question
I'm not 100% sure as to what you are trying to do, however, the relationship you describe could, I believe, be modeled as: Candles (candleid, description, price) Waxes (waxid, name/description) Candle_Waxes (candleid, waxid) Thus one table holds the description and price of each candle, another table holds the name of each wax, and a third table connects the two - as a candle can have multiple waxes, the logical way to do this (to me, anyway) is via this third table - glueing the other two together. You'll need to be a bit clever when querying, as simplying joining all three together will bring back multiple rows for candles which contain more than one wax - this could be eliminated by not bringing back the wax details (and using distinct), or in a number of other ways. One other way might be to come up with a way to combine all of the wax names into one field (tricky - can't think how to do this in mysql, off the top of my head). What precisely are you trying to achieve, though - this might be completely wrong for you!

Getting Aggregate Object Data
I'm in the process of trying to move some of our systems to MySQL from SQL Server and Oracle. At this point I'm learning and testing MySQL. One immediate question I have is regarding getting aggregate information. For example, the SHOW DATABASES command would be an example of something I would get from the SQL Server data dictionary table, sysdatabases. It appears that MySQL has no such mechanisms, and that you must rely on many of the SHOW commands. In the case of databases, it works great, but what about other objects? For example, if I want to see all indexes in my sales database? Or do I have to loop through each table with the SHOW INDEXES command? That's one example of what I'm talking about.

yeah, there's a whole lot wrong with that. 1. you're using the wrong versions of mysql, the freebsd sparc64 version wont work on solaris, perhaps you should get the solaris package? hrm, just a thought... and 2, it actually has to be installed before you try to run it, best option is to read the INSTALL-BINARY docs that come with the solaris version. trying to get a freebsd binary working on solaris is in for a world of pain tho.

However when I go to the link provided in the documentation http://search.cpan.org, I can't figure out how to find the Perl module. Can someone show me the light.

it mentions that the easiest way to install Perl DBI is to use CPAN. However when I go to the link provided in the documentation http://search.cpan.org, I can't figure out how to find the Perl module. Can someone show me the light. I'm not sure about the light, but when I typed in DBI in the search box at http://search.cpan.org and hit the search button it displayed a list of links and descriptions, the first of which was DBI. You can then either go to the descriptions DBI link or to the DBI-1.42 link just below it to get to the source directly.

Re: 5.0 on the Mac?
Thank you all for the responses. Looks like no one's had problems getting 5.0 running on the Mac. I'll be trying it after this weekend. If I have any problems, you'll be hearing from me again!

unique varchar in field
Hello again, How do you make a field unique, but not have it as part of the primary key? For example, I have a 'computers' table that has a 'comp_id' field that's the primary key. It's an int that's auto-incremented with each new entry. The same table has a 'comp_serial' field. I want this field to be unique, but I don't want it to be a part of the primary key, or any key for that matter. I just want it to be unique. How do I achieve this? Thanks, Brad -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

I don't know of any way to enforce uniqueness without making a unique key on the column.

RE: Using BYTEFX to connect to MySql , closing connection do not release the connection.
Thanks reggie, implement that and tested the scenario as per my first email, it work the desired way as per you have expected and suggested. My feeling about the second scenario is that it is a bug. Try this link and search for the exception text: http://cvs.sourceforge.net/viewcvs.py/mysqlnet/mysqlclient/MySqlPoolManager. cs?rev=1.4 it has been great help! :-)TweeWan -Original Message- From: Reggie Burnett [mailto:[EMAIL PROTECTED] Sent: 08 April 2004 22:23 To: 'tweewan.wong'; [EMAIL PROTECTED] Subject: RE: Using BYTEFX to connect to MySql , closing connection do not release the connection. I'm not sure why this is happening, but the behavior you described in the first email is correct pooling behavior. By default, connection pooling is enabled which means connections are not killed when they are closed but remain open and able to serve new connections if necessary. Only when the app quits is the pool manager collected and the connections killed. If this is not desired, you can add pooling=false to your connection string. -reggie -Original Message- From: tweewan.wong [mailto:[EMAIL PROTECTED] Sent: Wednesday, April 07, 2004 6:44 AM To: [EMAIL PROTECTED] Subject: RE: Using BYTEFX to connect to MySql , closing connection do not release the connection.

Hi, Encounter an interesting here using VB.NET with ByteFx.mysql.mysqlclient to connect to Mysql Database. I have a sub-form (called from another main form) with 4 mysqlconnections declared and new. X1= new mysqlconnection X1.connectionstring = a valid connection string X1.open() X2= new mysqlconnection X2.connectionstring = a valid connection string X2.open() X3= new mysqlconnection X3.connectionstring = a valid connection string X3.open() X4= new mysqlconnection X4.connectionstring = a valid connection string X4.open() Msgbox(Phase 1) X1.close() X2.close() X3.close() X4.close() Msgbox (Phase 2) I am using MySQL Administrator to monitor the connection , at the Phase 1 break point I can see that 4 connection is allocated. And at Phase 2 , I expect the connection will be closed, but to my surprise, it did not. Not until I quit entire application. Then I see the connections are release. Anyone has encounter this before and any pointers for me to investigate further?

Re: Why can't I use an AS value in the WHERE clause.
Mike, I see what you're saying `active` was the alias name not an actual column. Ironically I was using a HAVING clause because I agree with that last post. Mike, why keep the `IF` statement? You're really saying give me all the records where this expression is true. Why not just move the expression in the `IF` to the HAVING clause? So take my old statement and ditch the where clause. You'll get: SELECT * FROM wifi_table HAVING unix_timestamp()-unix_timestamp(last_seen) 600; A little easier on the eyes no?

RE: Too Many Connections
Run mysqladmin extended-status Look for something like this: | Max_used_connections | 138| If it says, 512 is your max connections that you have used, then you need to raise it. If your number is much lower and you are getting that problem, it's a different problem, but that's just what mysql is reporting.
