Hi This is not a "bug" in the documentation, it is the way you have interpreted what it says On a Win9x/ME system the Windows-System-Directory is called x:\Windows but in Windows NT and Windows 2000 it is called WinNT. If the author meant to write windows(winnt)\system that is what he would have written, not windows-system-directory. So I am sorry to say it is you that is wrong not the documentation writer.

Re: Database Planning
well, start with reading a book about designing databases, especially about
the subject 'normalisation'.
normalisation is a way to split up data ('entities') in a way that every
piece of data only occurs once in your database. (although sometimes for
practical reasons you may decide otherwise, but normalising your data is
always a good first step!)
Since you say newbies will like this, i'll try to give an example.
suppose you have a database of books. The database stores the book, it's
title and so on, the author, the publisher and the bookstores that sell this
particulair book:
book title description author author_address publisher publisher_address
bookshop bookshop_address [bookshop bookshop_addr], []
well, you could try to make this fit in one table, but you'll get a tough
time.
so, you split up ('normalise'):
books:
book_id
ISDN
title
description
author_id
publisher_id
authors:
author_id
author_name
author_addr
author_email
publishers:
publisher_id
publisher_name
publisher_addr
publisher_phone
publisher_email
bookshops:
bookshop_id
bookshop_name
bookshop_addr
bookshop_phone
availability:
available_id
book_id
bookshop_id
So, you split up your data in more elementary parts.
Especially notice how you create a table that links books to the bookshop
that sell those books, you only need the two id's from the book and the
bookshop.
If your very smart, you might figure out by yourself further. Elsewise i
still recommend to go to a (online) bookshop and get a nice book about
developing databases.

Subject: Database Planning
I realize this may be a little OT but I'm sure many of us MySQL rookies
would be interested in the responses.
I would be interested in hearing how someone goes about planning the
layout
of their database including how they determine what tables, fields, column
types, queries, etc they will need. How do you start the process? How do
you determine the correct questions to ask of your application? Do you
use
some kind of diagramming tool? Blah... Blah... Blah...
Thanks!

Help with LOAD DATA INFILE
If this is the incorrect place to ask, please feel free to point me in the right direction! I've got an old mySQL database that imports a load of data with LOAD DATA INFILE from a number of CSV files. One particular import is only processing about 50% of the 13,000-odd records. The LOAD command shows a large number of warnings on completion. Although I've got through the manuals, I can't see any pointers that would help me find out what these warnings relate to. I think if I can identify what the warnings are, I'll probably find out why I can't get the other 50% of the records. Clues, abuse and assistance gratefully received!

Re: Possible bug in 3.23.32 or later
As Far as I can remember it is explicitly said in the Manual that inserting

Subject: Possible bug in 3.23.32 or later
Description:
When i insert into a negative integer into primary key (id int) field, it
works fine.
However, the next insert i do without specifing the id explicitly and
relying on mysql to
generate the next number in the sequence (should be 1) will use the upper
bound (2^32 - 1)
Then every other insert after that will not insert since there are no id's
available.
How-To-Repeat:
CREATE TABLE category
(
idINT NOT NULL AUTO_INCRE17;6,
name VARCHAR(50) NOT NULL,
code VARCHAR(50) NOT NULL,
description TEXT,
picture VARCHAR(50),
parentINT NOT NULL DEFAULT 0,
activeTINYINT,
members INT NOT NULL DEFAULT 0,
storeid INT,
feature1 INT NOT NULL DEFAULT 0,
feature2 INT NOT NULL DEFAULT 0,
priority INT,
KEY (code),
KEY (name),
PRIMARY KEY (id)
)\g
INSERT INTO category
(id,name,code,description,picture,parent,active,members,storeid,feature1,fea
ture2) VALUES (-10,'NEW','NEW','All new products','none',-1,0,0,1,0,0);
Then try:
INSERT INTO category
(name,code,description,picture,parent,active,members,storeid,feature1,featur
e2) VALUES ('test','test','All test products','none',-1,0,0,1,0,0);
That should make the id 2^32 -1 (or something aroudn there).
That id should be 1!!!

Hi!
The above can not work on any system.
create table mytable (
(field defs)
);
This will cause parsing error on any system.
If the aobve is just an abbreviation, then you have most probably a
permission problem.

building advice needed on database structure
I have a database project, historic building materials... I've designed 4 Tables like this (there are more fields which I didn't listed here): table products - primary key(productid) - product description ... table category - primary key(categoryid) - category description table subcategory - primary key (Subcatid) - subcatdescription table subtype - primary key (suptypeid) - subtype description now I like to join those tables. For example I got the product of a single door (there are other doors which are double doors. This product belongs to subtype single doors, which than belongs to the subcategory doors and category historic building material out of wood. My aim is to have a hyperlink which shows me the categorys if click on it it shows me the subcategorys and than the subtype and than the products which belong to all this. So if I now create another table called for example table Ids - productID - categoryID - subcatID - subtypeID will I be able to join those together and get all I want to achive building it like this? Or do I have to many tables to join together? Also the Id's make up my product code say for example category b.m.o of wood makes number 10 (20, 30, 40 for others) subcategoryid will be 1 for doors (2,3,4 there after) subtype also 1 (2,3,4) and than the products will be 1, 2 , 3 etc. My logic doesn't let me think of any other way.

Hi!
Somewhere on Contrib or Link pages on our site there is a link to the
site devoted to building MySQL with Cygwin.
Also, after 3.23.37, there should not be any problem that you build it
yourself, provided you upgrade to gcc 2.95.2.

RE: Database Planning
The actualy tool I find that works the best is a sheet of paper.. or a white
board. I write down all the fields that are required. Then find out what I
can break out (normalize). After that I try to figure out what I can slice
away and still get the required data. For instance, say the book price is
$19.44. You also have a base cost of $18, and 8% tax. You can always write a
query to find out the total cost of any book, and get rid of anything to do
with the total cost in your tables. Finally I find that primary keys that
have no relation to data works the best.. You could have used the ISDN
number for the primary key of the book table, but it works out a whole lot
easier the other way. Also what I see all the time is text fields as primary
keys.. I hate that. Finally come up with some sort of logical naming
convention. There is a system called the Leszynski Naming Convention (LNC),
which I use where I work.
cost:
cost_id
book_id
curCost_base
intCost_tax_rate
curCost_total

Subject: Re: Database Planning
well, start with reading a book about designing databases, especially about
the subject 'normalisation'.
normalisation is a way to split up data ('entities') in a way that every
piece of data only occurs once in your database. (although sometimes for
practical reasons you may decide otherwise, but normalising your data is
always a good first step!)
Since you say newbies will like this, i'll try to give an example.
suppose you have a database of books. The database stores the book, it's
title and so on, the author, the publisher and the bookstores that sell this
particulair book:
book title description author author_address publisher publisher_address
bookshop bookshop_address [bookshop bookshop_addr], []
well, you could try to make this fit in one table, but you'll get a tough
time.
so, you split up ('normalise'):
books:
book_id
ISDN
title
description
author_id
publisher_id
authors:
author_id
author_name
author_addr
author_email
publishers:
publisher_id
publisher_name
publisher_addr
publisher_phone
publisher_email
bookshops:
bookshop_id
bookshop_name
bookshop_addr
bookshop_phone
availability:
available_id
book_id
bookshop_id
So, you split up your data in more elementary parts.
Especially notice how you create a table that links books to the bookshop
that sell those books, you only need the two id's from the book and the
bookshop.
If your very smart, you might figure out by yourself further. Elsewise i
still recommend to go to a (online) bookshop and get a nice book about
developing databases.

I realize this may be a little OT but I'm sure many of us MySQL rookies
would be interested in the responses.
I would be interested in hearing how someone goes about planning the
layout
of their database including how they determine what tables, fields, column
types, queries, etc they will need. How do you start the process? How do
you determine the correct questions to ask of your application? Do you
use
some kind of diagramming tool? Blah... Blah... Blah...
Thanks!

Re: use of the skip_networking option
You are correct. Mike Cermak wrote: This is probably a silly question, but I've read the one reference to skip_networking in the documentation and searched the archive (first rule of MySQL: RTFM, second rule of MySQL: read it again, third rule of MySQL: do an archive search on the term or concept you're looking for and read all relevant results), and I'm still not totally clear about something: If I'm setting up a MySQL server on RedHat Linux that will only be accessed via the following methods, can I safely start the server with the skip-networking option to more tightly secure the server? The access methods intended are: PHP or perl via web browser (for both queries and administration) console via Secure Shell (admin only, and only when necessary) local console (admin only, and only when necessary) I'm thinking that skip_netowrking will prevent any network-based connections other than via http (since the connection isn't to MySQL, but to the web server, which then locally connects to MySQL), and that console via SSH is not a network connection to MySQL, but a network connection to the console, which then locally connects to MySQL. Am I correct in my assessment? If skip_networking is used, does MySQL still advertise on port 3306? I'm thinking it shouldn't, but just want to be sure.

Corrupt tables after long queries
Hi all, Has anyone experienced anything like the following ? I have several queries which, admittedly, are quite complex and operate on several million rows of indexed data. The tables are naturally locked while the query occurs, which is fine, but what is *not* fine is that occasionally, completely unrelated tables end up needing a repair after thw long query has completed. The only pattern I can see is that towards the end of the query, I see a hell of a lot of "Opening table" "Closing table" status messages in the processlist - as soon as I see this, I can assume that the mentioned tables will have become corrupted - see a sample processlist below. Any ideas ?

Efficiency of MEDIUMTEXT columns?
Is it efficient to store things in MEDIUMTEXT columns? I am developing a web based system (using perl and MySQL) for viewing an archive of mailing list messages. In my database, I have one row per message. The column called "message" is of type MEDIUMTEXT. My perl code retrieves it using $sth-fetchrow_hashref and then prints it. Message size is typically ~10K; sometimes it's as high as a few hundred K. Here's an example URL from my site: http://qd.anifics.com/browse.asp?y=1995m=12d=30 I'm wondering if it's a good idea to use MEDIUMTEXT like this, or should I put the message body into individual separate files?

Re: Output from select is not what expected
Hi, It seems like you are not "joining" the tables in any way. Say you have: Table1 --- record1_id = 1 --- record2_id = 2 Table2 --- record1_id = 3 --- record2_id = 4 Table3 --- record1_id = 5 --- record2_id = 6 If you do a select all, you get all permutations: 1, 3, 5 1, 3, 6 1, 4, 5 1, 4, 6 2, 3, 5 2, 3, 6 2, 4, 5 2, 4, 6 * records. What you want is to link the tables in some way. For instance: table 1: id int name varchar(100) table 2: id int person int address blob select * from table1, table2 where table1.id = table2.person This will only pull out records in table2, where table2's current record has a value for field "person" equal to the value of "id" in the current record in table1. I suggest you get yourself a good SQL book (any suggestions anyone?) or have a look at some online tutorials: http://www.devshed.com/Server_Side/MySQL/Intro/ has a good overview of MySQL and some examples. http://www.wdvl.com/ is a good web devlopers resource, with tips and examples of different programming languages...

Re: Efficiency of MEDIUMTEXT columns?
Messages that are around 10k should be just fine, as long as they are the majority. A few tips for you... Store all the varchar/text columns for each message in a seperate table so that the primary message table only has fixed length fields (ie messageid, size, #of replies, userid, bodyid, ...). Then use the "bodyid" field as an index to the table that contains the varchar/text columns (you can do a left join on it when you need the bodies). This way it will be very fast for mysql to find a row in the primary message table. Also it will help you remember to not transfer the body unless you need it (try to make your queries return the fewest number of rows that you can live with because it reduces the strain on the server). One thing to keep in mind about using mysql with something like this with heavy load: inserts lock the table so you can not perform selects during that time (same with updates). So if you are dumping/posting a lot of messages into the table the select performance is going to suffer. If you make the inserts low priority and have a bunch of load they may not get inserted for quite a while. The innobase tables dont have this problem, but I dont think they support mediumtext column types because they have a row size limit (correct me if Im wrong). Hope this helps. ryan Is it efficient to store things in MEDIUMTEXT columns? I am developing a web based system (using perl and MySQL) for viewing an archive of mailing list messages. In my database, I have one row per message. The column called "message" is of type MEDIUMTEXT. My perl code retrieves it using $sth-fetchrow_hashref and then prints it. Message size is typically ~10K; sometimes it's as high as a few hundred K. Here's an example URL from my site: http://qd.anifics.com/browse.asp?y=1995m=12d=30 I'm wondering if it's a good idea to use MEDIUMTEXT like this, or should I put the message body into individual separate files? It runs fine right now, but I'm worried that it won't scale up under significant load. -Philip Mak ([EMAIL PROTECTED]) - 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: Plase Let us know if there is a Racialism for Mysql product and quit
lol. guess yusuf gots some point here. Obviously, for one reason or another m$ decided to place some files in the %windir%, and some in the %windir%\system32 dir. Although it never became totally clear to me what structure they had in mind (if there is any). Roughly said: %windir% is for executables, .ini files and other stuff, and %windir%\system32 for 32-bit dll's (and %windir%\system for 16 bit dll's). but hey, take a look at a random installation, and you see loads of (especially big...) companies messing up. In the end, windows doesn't care at all where .dll's , and lot of other stuff, is placed, as long as it is in the path.

Syncronization
Here's the situation. I have two application servers, each running their own mysql databases. If one goes down, the other takes over for it. But when it comes back up, whatever user preferences were stored on the other server during the downtime are lost. I need a way to syncronize the databases. This needs only be a periodic process, say once a day or so, running at command line with no environmental dependencies. It is not the case that one app server is the main and the other is the backup, they are both main servers, both maintaining separate lists of info, even though the type of info they store is the same (ie the load is just balanced between the two).So i need a way to do a two-way sync, so that if a situation like this arises, the user prefs are not totally from the server that went down lost. It isn't especially important to mirror everything on both servers up to the transaction. A loss of preferences over a day or two isn't that big a deal. Just something to sync them once a day so the information on both is relatively current in the context of say weeks rather than days. Suggestions? -- A.

Corrupt tables after long queries (fwd)
Hi all, Has anyone experienced anything like the following ? I have several queries which, admittedly, are quite complex and operate on several million rows of indexed data. The tables are naturally locked while the query occurs, which is fine, but what is *not* fine is that occasionally, completely unrelated tables end up needing a repair after the long query has completed. The only pattern I can see is that towards the end of the query, I see a hell of a lot of "Opening table" "Closing table" status messages in the processlist - as soon as I see this, I can assume that the mentioned tables will have become corrupted - see a sample processlist below. Any ideas ?

Re: Database Planning
I just got done figuring out how to --100%-- normalize a database to make it very flexible. Methinks that Oracle has done this in some fashion, as they claim to be able to make an intersection from any row in any table to any other. A note: Objects, Actors, and Attributes use the names of the tables having 0:1 relationships to them as the value in their name . Example: Actors ActorID=1,TypeID=1,Name=Company ActorID=2,TypeID=1,Name=Company ActorID=3,TypeID=2,Name=Member Objects ObjectID=1,TypeID=1,Name=Schedules ObjectID=1,TypeID=2,Name=Bookings ObjectID=1,TypeID=2,Name=Bookings the database application code/constraints, or scripts accessing the database have to enforce that no ObjectID,ActorID,AttributeID EVER gets used twice and only appears in once of the tables in 0:1 relationship to it.

Re: getting started...the hardest part
You've got a long way to go. "tar" is short for tape archive. It is an ancient unix utility that takes directory and file data and builds it into a contiguous data base file. This is for portability and manageability. You should have to get past "gzip" before you get to "tar". gzip is a gnu compression utility. The mysql tarball is tar'd and gzip'd so one normally has to; gzip -d mysql.tar.gz tar -xvf mysql.tar That leaves you with a directory you need to enter and "make install". Read the INSTALL and README files. They'll get you through it OK. The reason for GNU TAR is that the Solaris "tar" has a 128 charachter path limit to filenames. I think MySQL exceeds that with the windows32 stuff. Warning! Solaris has a number of other problems out of the box. The "cc" compiler is bad, as is the "ld" or linker libraries. If your serious about using open source software you'd be best to go to www.gnu.org and get; gzip bin utilities make tar gcc Your best off to compile and install them so they are custom to your current solaris' environment. It goes something like; gzip -d whatever.tar.gz tar -xvf whatever.tar cd whatever ./configure make make install Compile and install all of these, add /usr/local/bin to your path; PATH=$PATH:/usr/local/bin:/usr/local/lib export PATH You are then "in the ball park". It's a tough haul. The solaris 2.8 CD has a lot of these gnu utilities pre-compiled for Solaris. These can help but the practice of compiling and installing the minor support libs can set you up better for the big installs. If solaris wasn't such a rock solid OS on rock solid hardware I'd recommend setting up FreeBSD on an old intel box. It's easier but not as robust as freeBSD's development environment is "GNU/BSD" centric as are most open source efforts. Simon Chan wrote: Hi Everybody!

Installing all prepared tables
After posting yesterday about mysql_install_db haning when it says "Installing all prepared tables" I've tried the rpm version, and it hangs in the exact same place. How do I get it to work? The other posts suggest that it's a permissions problem. If that's the case, what do my permissions need to be? I've tried setting various ownerships and privs and nothing works. I've also tried "scripts/mysql_install_db --user=mysql" and that doesn't work either. Any help would be greatly appreciated. I'm about to tear all my hair out.

sql_create_basic_N questions
NOTE: I have cross-posted this to the plusplus mailing list as well.
I am using sql_create_basic_N to generate structures that mirror my database
tables. The problem I have is that some of the fields in my database are
"blobs" that need to be escaped before insertion.
Questions:
1. I am using a string to represent the data in the structure:
sql_create_basic_2(StoryBody, 0, 0,
INT32, StoryID,
string, Body);// this is actually a blob
Is there a better data structure for this?
2. The data that I am trying to store has nulls scattered throughout. When
I create the insert string using the following code, it only puts in the
data up to the first null. That's a side effect of the string, so I have
tried escaping the string before I create the insert statement. That
doesn't seem to work either. Apparently, MySql is ignoring the escaped
characters.
StoryBodysb;
sb.StoryID = -1;
string tmpS(blobSize, blob);
sb.Body = tmpS;
escape_string(sb.Body);
Query q = m_dbconn-query();
stringstream strbuf;
try {
string tmpQS = "INSERT INTO STORYBODY (Body) VALUES('";
strbuf "INSERT INTO STORYBODY (Body) VALUES(" quote sb.Body
")";
q.exec(strbuf.str());
} catch(BadQuery e) {
// handle error here
}
Any help would be greatly appreciated.
Thanks,
Steve
Re: ADO RS.Update problem
- Original Message - From: "Pat Sherrill" [EMAIL PROTECTED] Sent: Saturday, April 14, 2001 7:34 AM Subject: Re: ADO RS.Update problem Just a quick note about RecordCount. RecordCount only returns the number of records or rows from the recordset that have been 'seen'. Therefore it is only reliable if you have traversed the entire recordset before calling it. That is true in some cases, using MoveLast and then issuing the RecordCount request does give the most accurate result. However, if I remember correctly, when working with MySQL and ADO, MoveNext is one of the few methods that is supported. Further note that even if all the records are "seen" (by using a loop and MoveNext), the RecordCount property will still not work. Therefore, the work-around would require a separate counter with ASP or other language of choice.

Re: question about integrating ASP pages
Is it possible to use ASP with MySQL? I found a link in the documentation to www.amedea.cz/mysqlx/index.html which was supposed to have a downloadable MySQL COM extension but the website was not found. Yes, it's possible to use ASP with MySQL. In a nutshell, you need to make sure that you have the MyODBC driver installed on your server and you can then create a connection object with the DSN name. From there, you will be able to work with it almost like any other connection recordset object, although there are some limitations with a few ADO properties. PLUG I wrote a case study for ASPToday that address this very issue (ASP and MySQL integration).

RE: Inserting data to multiple table at once
Yeah, it does require one insert command per table, thats why some people
like transaction capability in tables. If we all could insert data into
multiple tables with one insert command then we wouldn't need transaction
support would we? H, that would be nice though! :o)

Re: Efficiency of MEDIUMTEXT columns?
On Wed, 18 Apr 2001, ryc wrote:
A few tips for you... Store all the varchar/text columns for each message in
a seperate table so that the primary message table only has fixed length
fields (ie messageid, size, #of replies, userid, bodyid, ...).
I have some VARCHAR columns (name, e-mail address and subject) that are
used in every query, though. Should I change them to CHAR(255) so that I
can do this? (On a related note, does anyone know whether the RFC for
e-mail messages limit the subject length/name length/e-mail address length
to a certain number of characters? What is this number?)
Also, is it a good idea to make a field called size and use that instead
of calling length(message) (message is MEDIUMTEXT) when I don't need to
retrieve message, or does MySQL have length(message) cached?
...
I just ran a crude benchmark on three different ways to retrieve text from
the database. The time required for 100 iterations of each method is:
DB2: 3.7 seconds
DB3: 11.5 seconds
Text: 5.6 seconds
DB2 is where I retrieve the message from the database:
my $sth = query("SELECT * FROM ffml WHERE num=6051");
my $this = $sth-fetchrow_hashref;
print $this-{message};
DB3 is where I retrieve the message from the database and split it:
my $sth = query("SELECT * FROM ffml WHERE num=6051");
my $this = $sth-fetchrow_hashref;
my @message = split("\n", $this-{message});
for my $line (@message) { print $line."\n"; }
Text is where I retrieve the message from a disk file:
open(MSG, '6051');
while ($line = MSG) { print $line."\n"; }
So it would appear that retrieving a message (the message that I used in
this test is 300k, about the largest that is in the archive) from the
database is faster than loading it from a disk file. However, when I have
to split() the message into a list (one entry per line), it becomes
slower. Any idea how I can split it more efficiently? (My code has to
process each line individually in order to hilight text from quoted
replies; e.g. look at the different colors in
http://qd.anifics.com/read.asp?num=32)
So if you are dumping/posting a lot of messages into the table the
select performance is going to suffer.
Inserts shouldn't be too common; just once every time the mailing list
receives a new message (no more than 100 per day).

Marino wrote: You've got a long way to go. "tar" is short for tape archive. It is an ancient unix utility that takes directory and file data and builds it into a contiguous data base file. This is for portability and manageability. You should have to get past "gzip" before you get to "tar". gzip is a gnu compression utility. The mysql tarball is tar'd and gzip'd so one normally has to; gzip -d mysql.tar.gz tar -xvf mysql.tar That leaves you with a directory you need to enter and "make install". Read the INSTALL and README files. They'll get you through it OK. The reason for GNU TAR is that the Solaris "tar" has a 128 charachter path limit to filenames. I think MySQL exceeds that with the windows32 stuff. Warning! Solaris has a number of other problems out of the box. The "cc" compiler is bad, as is the "ld" or linker libraries. If your serious about using open source software you'd be best to go to www.gnu.org and get; gzip bin utilities make tar gcc Your best off to compile and install them so they are custom to your current solaris' environment. It goes something like; gzip -d whatever.tar.gz tar -xvf whatever.tar cd whatever ./configure make make install Compile and install all of these, add /usr/local/bin to your path; PATH=$PATH:/usr/local/bin:/usr/local/lib export PATH You are then "in the ball park". It's a tough haul. The solaris 2.8 CD has a lot of these gnu utilities pre-compiled for Solaris. These can help but the practice of compiling and installing the minor support libs can set you up better for the big installs. If solaris wasn't such a rock solid OS on rock solid hardware I'd recommend setting up FreeBSD on an old intel box. It's easier but not as robust as freeBSD's development environment is "GNU/BSD" centric as are most open source efforts. Simon Chan wrote: Hi Everybody!

Phrase based fulltext searching

This way if someone posts 100 messages, you only store their email address once. The subject field is a bit more tricky. You COULD change it to Char(255) but that would waste a lot of space seeing that most subjects are a lot shorter. You can move the subject into the table that holds the varchar bodies. This wont hurt anything because that table already has varaible length rows from the body column, adding the subject wont hurt. Also, is it a good idea to make a field called size and use that instead of calling length(message) (message is MEDIUMTEXT) when I don't need to retrieve message, or does MySQL have length(message) cached? Yes definitly. Although it is tempting to calculate the length/count/other stats on the fly using database functions, it is not scalable. For any stat type field like length(in your case size) ask yourself how often it changes. If it doesnt change often or at all, it is much better to calculate it once and store 'cache' the result in the database. Do the same for number of replies (ie dont calculate them on the fly). Otherwise you are going to find yourself with 500k rows and the counting replies isnt so fast anymore. So it would appear that retrieving a message (the message that I used in this test is 300k, about the largest that is in the archive) from the database is faster than loading it from a disk file.

Instead of splitting it into lines based on a newline, you can do a global replace using \n as an anchor. Something like: search for "\n" and replace with "\n$colorcolor". I am not sure if this would be much faster than doing a split you can try it out. But again thinking scalability you might want to do this conversion once, and store the results in the database. So you dont have to worry about parsing it into lines once you retrieve it from the db, you can just spit it out because it already has the color info in it. ryan - 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?

MySQL 3.23.37 released
Hi! 3.23.37 is now released. This release mainly fixes some minor bugs, so we assume that most users doesn't have to upgrade from 3.23.36. The main change is that Innobase tables changed name to InnoDB to not conflict with the German INNOBASE company. If you are using Innobase, you need to change all your options in your startup and config files from innobase to innodb. (You can still create tables with type=INNOBASE, but this should be changed to type=INNODB over time). We are just now building the first MySQL-Max binaries with support for Berkeley DB and InnoDB tables. The first one will be a Linux x86 RPM (which should be available tomorrow), but other binaries should be available within a few days (or when 3.23.38 is released if we have to do any major porting change). Because of a problem on our windows computer, the windows version of 3.23.37 will be delayed a couple of days. Changes in release 3.23.37 -- * Fixed a bug when using `HEAP' tables with `LIKE'. * Added `--mysql-version' to `safe_mysqld' * Changed `INNOBASE' to `InnoDB' (because the `INNOBASE' name was already used). All `configure' options and `mysqld' start options are now using `innodb' instead of `innobase'. This means that you have to change any configuration files where you have used `innobase' options before upgrading to this version! * Fixed bug when using indexes on `CHAR(255) NULL' columns. * Slave thread will now be started even if `master-host' is not set, as long as `server-id' is set and valid `master.info' is present * Partial updates ( terminated with kill) are now logged with a special error code to the binary log. Slave will refuse to execute them if the error code indicates the update was terminated abnormally, and will have to be recovered with `SET SQL_SLAVE_SKIP_COUNTER=1; SLAVE START' after a manual sanity check/correction of data integrity * Fixed bug that erroneously logged a drop of internal temporary table on thread termination to the binary log - bug affected replication * Fixed a bug in `REGEXP()' on 64-bit machines. * `UPDATE' and `DELETE' with `WHERE unique_key_part IS NULL' didn't update/delete all rows. * Disabled `INSERT DELAYED' for tables that supports transactions. * Fixed bug when using date functions on `TEXT'/`BLOB' column with wrong date format. * UDF's now also works on windows. (Patch by Ralph Mason) * Fixed bug in `ALTER TABLE' and `LOAD DATA INFILE' that disabled key-sorting. These command should now be faster in most cases. * Fixed performance bug where reopened tables (tables that had been waiting for `FLUSH' or `REPAIR') would not use indexes for the next query. * Fixed problem with `ALTER TABLE' to Innobase tables on Freebsd. * Added `mysqld' variables `myisam_max_sort_file_size' and `myisam_max_extra_sort_file_size'. * Initialize signals early to avoid problem with signals in Innobase. * Applied patch for the `tis620' character set to make comparisons case-independent and to fix a bug in `LIKE' for this character set. *NOTE*: All tables that uses the `tis620' character set must be fixed with `myisamchk -r' or `REPAIR TABLE' ! * Added `--skip-safemalloc' option to `mysqld'.

Re: Efficiency of MEDIUMTEXT columns?
On Wed, 18 Apr 2001, ryc wrote: The subject field is a bit more tricky. You COULD change it to Char(255) but that would waste a lot of space seeing that most subjects are a lot shorter. You can move the subject into the table that holds the varchar bodies. This wont hurt anything because that table already has varaible length rows from the body column, adding the subject wont hurt. Well, I was wondering if there is a point in putting the SUBJECT field in a separate table, when every query that I would execute needs to retrieve the SUBJECT field anyway... Also, is it a good idea to make a field called size and use that instead of calling length(message) (message is MEDIUMTEXT) when I don't need to retrieve message, or does MySQL have length(message) cached? Yes definitly. Although it is tempting to calculate the length/count/other stats on the fly using database functions, it is not scalable. Okay, I'll do that. The messages don't change once they're posted so it's easy to keep another field indicating the size. Instead of splitting it into lines based on a newline, you can do a global replace using \n as an anchor. Something like: search for "\n" and replace with "\n$colorcolor". It's not quite that simple; the color changes depending on how many 's there are. My current algorithm counts the (number of 's + 1) % 6 at the beginning of the line to decide what color to use. If this were C, I could probably do this efficiently using character pointers. Come to think of it, when I split the message into a list, that causes two copies of the message to be held in memory: the unsplit version, and the split version. Maybe that's what's slowing it down. I can't think of doing it any other way though. thinking scalability you might want to do this conversion once, and store the results in the database. So you dont have to worry about parsing it into lines once you retrieve it from the db, you can just spit it out because it already has the color info in it. I might do that once I get my system better developed. Most pages never change once they've been created, and the ones that do change (e.g. when a message gets replied to, its page needs to link to the new reply) can be found and updated relatively simply. So I could just write out a lot of this stuff to static HTML pages for the ultimate performance boost. -Philip Mak ([EMAIL PROTECTED]) - 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: starting MySql on redhat 7
I don't know if you have fixed this probelm, but I had the same problem on Red Hat 7.0. I had installed the rpm files from MySQL.com and RedHat.com. The problem was solved by doing the following. chmod 755 the "mysql" directory that contains the "mysql.sock" file. I am currently running the latest release of MySQL Server Client. Don't take this advice as perfect. I am a newbie also. Mike, "bobit" [EMAIL PROTECTED] wrote .. Hi - here's my prob and background info. Tried the fix - it didn't work. MySQL Connection Failed: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (111) Any thoughts...? I'm not sure if it's the same problem but here goes: I just did a fresh install of RH 7.0 with apache, php, and mysql. I had the same problem. All I had to do was change the permissions on my MySQL directory (in your case "/var/lib/mysql") so that my apache user (the user/group that apache runs as) has access. check to make sure it also changes permissions on the mysql.sock file. That's the important one. I believe apache only needs read (maybe execute) access. chmod 755 /var/lib/mysql (that's from memory, but you know the gist of the problem) Groan..I knew linux was tough but I didn't think I needed a black belt. I've got exactly the same prob after a straight redhat7 install. I tried to take milner's advice and: changed the /var/lib/mysql/mysql.sock to 755 for root who I'm logged in as. Then tried to do the same thing for the Mysql directory. It won't change. Tried a re-boot. Then figured there was something screwy with the directory. Moved mysql.sock to /test rmdir mysql mkdir mysql copied the file back in. The file now had rw permissions only. But in the test dir root had all the permissions to it. Is it being blocked higher up in the tree. My linux book isn't very good on dir permissions. Will chmod change these even if the directory is not empty. And how do u list permissions to a directory? ls -l only seems to work for files. In the error log in the same directory I also get: mysql.host doesn't exist - but this may be a susequent error.

That doesn't make really sense. According to the SQL specification, without ORDER BY the records are retrieved in an undefined order. Inverting an undefined order makes the records still being in an undefined order. You see my point? It seems that you are relying on the internal order of MySQL, which is considered a *Bad Thing*. MySQL is free to change this order at will, any time. According to the specification, if you leave out the ORDER BY clause, generally spoken, an RDBMS is even allowed to return the records in different order each time you run the same query! And there is no guarantee that the next MySQL version won't do exactly that (even if it is very, very unlikely). So you may want to describe to us what you want to archieve (why do you want that inverting) and maybe someone will come up with a solution.

Weird Ordering Queries
Ive come up with a curly problem and im wondering if anyone can shed some
lights on it. I looked under the SELECT part of Mysql but it didnt seem to
cover this and I didnt know how to phrase it.
What I have is a displayed list on the site. This data that makes up the
list comes from 2 tables. 'item' and 'location' are the 2 table names. For
each item there is 1 entry in the item table. But under location there is
several entries depending on where the part is. Its done this way to log a
history of whether the item has been sent out, or received in. Each entry
in the location table is date stamped and records the items location, and
the item_id field.
Currently I am doing my list like this.
$item_q=mysql_query("select * from item order by item name");
while ($item=mysql_fetch_array($item_q)) {
$location_q=mysql_query("select * from location where
item_id=$item_q[item_id] order by date desc limit=1");
$location=mysql_fetch_array($location_q);
echo"$itemlist[item_name] - $location[location] - $location[date]";
}
The reason I do it this way is that I firstly need it to list all items,
but then next step (and next SELECT) it grabs the most recent entry in
location for that item. My problem is, I need to be able to combine the
SELECT queries into 1, so that I can order by either Location, Date or Name
Im not sure if this sort of thing is possible but it would make life so
much easier if I could do it.
Thanks
