MySQL
A while ago we chatted about a better MySQL search engine. So, I wrote a script to turn the list emails into web pages, and set these into a directory, then installed the Alkaline search engine, and added www.mysql.com to the list of sites to index. the url is here http://workinout.com:9998/workinout/search.html It should be up most of the time, and over time, I will add improvements. Its fast, and simple to use, and its 100% MySQL related. Comments welcome anytime.

Slave on same machine?
Hi, I know, it sounds a bit like a stupid question, but can I run a slave mysqld server on the same machine? The idea of just running a slave for the purpose of bringing it down, each night, to make a backup, is quite appealing. I now use the hotcopy method.

Displaying news across several pages
Hi, I am a beginner in this MySQL thing, and i am trying to figure out how i can split, for example, some news articles i already have in a table, into several pages. On the site i am building, i get the 10 first news and display them. I use SELECT FROM NEWS ... ORDER BY DATE DESC LIMIT 10. Is there any mysql command to select the next 10 items, for example? something like LIMIT from 10 to 20 hehe, i know it sounds weird. :-) Thanks.

permission or config error
Hello,
Probably a question that has been asked a million times before, I searched
google and it
has been brought up before but there didn't seem to be that many solutions
and alot fo the
time it would just Start working.
Anyway,I have just set up my mysql server
Server version: 3.23.54
Protocol version: 10
Connection: Localhost via UNIX socket
UNIX socket:/var/lib/mysql/mysql.sock
and wrote a little php test script to access the database (not php is
configured properly and works
when it is just plain php but as soon as it (tries to) connect to the
database all fails).
?
$connection=mysql_connect(localhost,melinda,mypasswd);
$connection= mysql_connect(localhost,melinda,mypassswd) or
die(Couldn't connect);
if($connection)
{
$msg=success;
}
?
? echo $msg; ?
The message I get when I connect is:
Warning: Can't connect to local MySQL server through socket
'/tmp/mysql.sock' (2) in /home/melinda/public_html/test-sql.php on line 2
Warning: MySQL Connection Failed: Can't connect to local MySQL server

Warning: MySQL Connection Failed: Can't connect to local MySQL server
through socket '/tmp/mysql.sock' (2) in
/home/melinda/public_html/test-sql.php on line 3
Couldn't connect
I am still trying to understand all the info on access but I did setup the
user melinda as follows:
mysql use mysql
Database changed
mysql insert into user (host, user, password) values('localhost',
'melinda',password('mypasswd'));
- then flushed privileges
mysqladmin -u root -p flush-privileges
and I can login to mysql as the user melinda.
Is the error message above due the fact that I have not enabled some other
permission or it simply due to the fact that
the socket is in /var/lib/mysql/mysql.sock not in /tmp/ and if so how do I
tell it that the socket file is in /var/lib
Many Thanks,
Melinda

Re[2]: Storeing images in Database
Dobrý den, sexta-feira, 24 de janeiro de 2003, 22:41:47, napsal jste: WRM Since you obviously aren't going to search the images themselves there is WRM no reason to put them into a database. File systems are designed for WRM this. I might suggest using an Id field and then split them into WRM subdirectories based on the 1st or last digit of the ID (0..9). This WRM would reduce the number of files in a given directory which can be a WRM problem with VERY large numbers of files. You can also put them on a WRM totally differnet drive from the database data to increase performance. WRM The cost is bit of setup (have to create the directories) and WRM programming. This should allow the database rows to be uniform in size WRM which should help performance. OK , but my database is only for images... and i want integrate my client application with the Internet page around the world ... What is more easy, one select and get image or a connection to download the image ? The point is this. in my case... the images in sql database is more comfortable , but is it secure ? you loose data using BLOB fields ? please send me a reply to help me in my decision :) The suggestion bout ID in database and store an a file system, it is very interesting , but if i loose the id´s ? atomically i loose the images correct ?

How to speed things up in MySQL ?
Hello, While reading this you may think this is off-topic... but please read on.. I'll get on-topic in the end :-)) First of all I have Web Server on which I have a Paradox table with 320 records. I also have a CGI Script (or program if you like) I made in Borland Delphi which I use to access the Table... When I enter the address of my CGI-script in my Internet Browser the following happens: The CGI script on the Web Server is starting. The CGI script reads the SQL command to execute passed on to the script through the HTTP protocol. The CGI script establish connection with the Borland Database Engine (Loading BDE dll's etc..) The CGI script opens/initialize the Paradox Table. The CGI script execute the SQL command sent to it. The CGI script sends back the result of the SQL command to the Browser (HTTP protocol). The CGI script closes down (shutting down db connection etc..). My PC and my Web Server is connected on the same LAN (switched 100 MBit/s) All of the above is completed in 1.5 seconds. ** here the fun begins ** I have now successfully installed MySQL (on the same WebServer) and converted the Paradox Table to MySQL Table type: MyISAM. Database Name: TDD Table Name: DVD This new Table contains the same 320 records using the same field definition as in the Paradox Table. On my Web Server I go into \MySQL\bin\ and start mysql -uroot -p and execute the same SQL command as sent to the Paradox table through the CGI script. see screen dump below for result.

How to combine two selects into one ???
Hi! I need to make a select which is the combined result of 2 selects. I assume I could do this in v4 using UNION or in v3 by running 2 select into statements, however I'd prefer to do it in v3.23 and if possible with just one select and just read permissions. The table is like this : mysql desc process; ++---+--+-+- +---+ | Field | Type | Null | Key | Default | Extra | ++---+--+-+- +---+ | timecode | datetime | | | -00-00 00:00:00 | | | systemid | smallint(5) unsigned | | MUL | 0 | | | username | varchar(20) | | | | | | cpuusage | float(4,2)| YES | | NULL | | ++---+--+-+- +---+ It's a table containing unix users and their cpu usage. The table contain more info about processnames memory usage per process etc. etc.. I first make a select to find the 2 users with the most CPU usage : SELECT username, sum(cpuusage) AS sum_cpuusage FROM process WHERE systemid = '2' AND timecode now() - INTERVAL 1 DAY GROUP BY username ORDER BY sum_cpuusage DESC LIMIT 2 I then use the result from this select to make a new select with the format timecode, user1, user2, user3 etc... where user1, user2 etc. is the sum() of these users cpu usage at any given timecode. I use sum because every user can have more than one process active at any given time, and I store all active (cpu using) processes in the database. What I want is the combined output of selects like these (example with 2 users) : SELECT timecode, sum(cpuusage) AS jfn FROM process WHERE systemid = '2' AND username = 'jfn' AND timecode now() - INTERVAL 1 DAY GROUP BY timecode ORDER BY timecode SELECT timecode, sum(cpuusage) AS root FROM process WHERE systemid = '2' AND username = 'root' AND timecode now() - INTERVAL 1 DAY GROUP BY timecode ORDER BY timecode With combined I mean that I want it in the form timecode, jfn, root. How do I rewrite this into one select, and can it be done without having to use features only present in v4, or features that require write access to the database ??? For people who want to test/try the real database, there's a read only web interface at http://statdb.dassic.com/sql.php The 2 queries from the example that I want to combine into one produce useful data, so the question is just to merge them into one, since the goal is to later, using another interface, ask a PHP script to draw a graph with a top 5 of CPU usage among users. To do this I need a output like this : timecode, user1, user2, user3 etc. /Jesper - 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?

Hello, While reading this you may think this is off-topic... but please read on.. I'll get on-topic in the end :-)) First of all I have Web Server on which I have a Paradox table with 320 records. I also have a CGI Script (or program if you like) I made in Borland Delphi which I use to access the Table... When I enter the address of my CGI-script in my Internet Browser the following happens: The CGI script on the Web Server is starting. The CGI script reads the SQL command to execute passed on to the script through the HTTP protocol. The CGI script establish connection with the Borland Database Engine (Loading BDE dll's etc..) The CGI script opens/initialize the Paradox Table. The CGI script execute the SQL command sent to it. The CGI script sends back the result of the SQL command to the Browser (HTTP protocol). The CGI script closes down (shutting down db connection etc..). My PC and my Web Server is connected on the same LAN (switched 100 MBit/s) All of the above is completed in 1.5 seconds. ** here the fun begins ** I have now successfully installed MySQL (on the same WebServer) and converted the Paradox Table to MySQL Table type: MyISAM. Database Name: TDD Table Name: DVD This new Table contains the same 320 records using the same field definition as in the Paradox Table.

Re: How to speed things up in MySQL ?

Good question. I do not know the answer, but I can tell you that there is something seriously screwed up. It should only take a fraction of a second. When I run a similar query on my database, it displays 0.00 sec, i.e. it took less than 0.01 secs. The same query on a database with 600.000 records takes about 4.7 secs. And this was when I was directly logged on to the Database (via Localhost)! When Using my Paradox table this took 1.5 second through my CGI script over the Intranet. [...] What can I do to speed this up ? As I said, I am not sure. This is not a question of optimizing your database or queries. Your installation of MySQL does not behave normally. Usually, there is no way any operation on 320 records would take more than at most 0.1 seconds or such. PS: The DVD table containing the 320 records is the only table on the server. (except from the MySQL database and the empy Test Database). Both the Paradox Table and the MySQL server is installed on the same Harddrive so harddisk speed shouldn't be a factor. Harddrive speed shouldn't be a factor at all, as 320 records need so few memory that they usually are kept in memory after first access. Appreciate any help to solve the above :-))) Just to be sure to exclude anything I might not have thought of, can you post the result of EXPLAIN for the select above SHOW CREATE TABLE DVD SHOW INDEX FROM DVD SHOW TABLE STATUS LIKE 'DVD' Is there anything running on the server while you do your tests?

Re: How to combine two selects into one ???

What I want is the combined output of selects like these (example with 2
users) :

AND timecode now() - INTERVAL 1 DAY

With combined I mean that I want it in the form timecode, jfn, root.
How do I rewrite this into one select, and can it be done without having
to use features only present in v4, or features that require write
access to the database ???
If I understand you correcty, the following should do what you
want (untested):
SELECT timecode,
SUM(IF(username='jfn',cpuusage,0)),
SUM(IF(username='root',cpuusage,0))
FROM process
WHEREsystemid = 2 AND
timecode now() - INTERVAL 1 DAY AND
username in ('jfn', 'root')
GROUP BY timecode
ORDER BY timecode
Note that it will be somewhat slower than two seperate queries, I
think.
For people who want to test/try the real database, there's a read only
web interface at http://statdb.dassic.com/sql.php
The 2 queries from the example that I want to combine into one produce
useful data, so the question is just to merge them into one, since the
goal is to later, using another interface, ask a PHP script to draw a
graph with a top 5 of CPU usage among users. To do this I need a output
like this :
timecode, user1, user2, user3 etc.
For that application, I do not see why the output of something like
SELECT timecode, user, SUM(cpuusage)
FROM process
WHEREsystemid = 2 AND
timecode now() - INTERVAL 1 DAY AND
username in ('jfn', 'root')
GROUP BY timecode, user
ORDER BY timecode, user
is not enough. That is easily post-processed in the application.
HTH,
Benjamin.

RE: Need nulls in my join
Unfortunately I tried to implement what you suggested, but in my case it didn't work. I have stories that can have zero or more photos, one or more author, one or more sections, and one or more active dates. Trying to join all those items together using your suggestion actually did return stories with no photo, but I would then get 3 copies of a story that had 3 photos, and 6 copies of a 2-photo story that appears on 3 days. What I really need is mysql 4's SELECT blah WHERE (SELECT blah) subselect feature, but that's not an option either due to the host I'm using. I ended up writing a simpler query get all the unique story id's for a section, then doing a foreach loop in PHP to query for all the additional data for the story where ID = $loopindex. I'm sure there's a supermysqlguru out there who cringes when you issue a bunch of queries in a PHP loop, but it works fine for now.

Re: How to speed things up in MySQL ?
Hi Bhavin.
Thanks for taking interest in my problem...
Here is the table definition as requested.
I'm sorry I could take a full dump... Each record consist of approx 600 KB
(just as in the Paradox table) so the file would be very big. (200 MB).
Kind Regards

Hello,
While reading this you may think this is off-topic... but please read
on..
I'll get on-topic in the end :-))
First of all I have Web Server on which I have a Paradox table with 320
records.
I also have a CGI Script (or program if you like) I made in Borland
Delphi
which I use to access the Table...
When I enter the address of my CGI-script in my Internet Browser the
following happens:
The CGI script on the Web Server is starting.
The CGI script reads the SQL command to execute passed on to the
script
through the HTTP protocol.
The CGI script establish connection with the Borland Database Engine
(Loading BDE dll's etc..)
The CGI script opens/initialize the Paradox Table.
The CGI script execute the SQL command sent to it.
The CGI script sends back the result of the SQL command to the
Browser
(HTTP protocol).
The CGI script closes down (shutting down db connection etc..).
My PC and my Web Server is connected on the same LAN (switched 100
MBit/s)
All of the above is completed in 1.5 seconds.
** here the fun begins **
I have now successfully installed MySQL (on the same WebServer) and
converted the Paradox Table to MySQL Table type: MyISAM.
Database Name: TDD
Table Name: DVD
This new Table contains the same 320 records using the same field
definition
as in the Paradox Table.
On my Web Server I go into \MySQL\bin\ and start mysql -uroot -p and
execute the same SQL command as sent to the Paradox table through the
CGI
script. see screen dump below for result.

good manner for handling multiple languages dynamic websites
Hello, I have, for the first time, a website to do in several languages. I'll do a variable replacement whereever needed, with several lang files (as I've seen so many times in open source PHP applications) but I am wondering how in sql I could do for translating items' names.. I explain : I have a site in english, where the user posts an ad, when he has to choose the color of his object, he chooses RED I will store RED,BLUE,GREEN,etc. in a table 'color' so I can build a dropdown list for the user to choose from well now, if a visitor browse the ads in french. I'd like the color to read 'rouge' not 'red'. How should I go about that, database items ? Cheers if you see what sort of problem I am facing right now.

Charset and French Diacritic Characters
Hello everybody, I'm french and use MySQL 3.23.40 on the Windows environment. And I have a problem with the special french characters (é, è, ê, à, â, etc.)... I want that the search queries are insensitive to those special characters. So that, for example, the é character is handled as the e character. and the query élégant finds elegant. A very common problem I think, but until now I have no simple solution (and find nothing interesting on the Net) ! I read the MySQL manual about the charsets and their handling. It seeems that, for a given charset, sorting, upper casing and lower casing are done according to the configuration stored into the charset.conf file... (with the 4 arrays ctype[ ], to_lower[ ], to_upper[ ] and sort_order[ ]). By default, the charset used by my MySQL is Latin1. According to the Latin1.conf file (and the sort_order[ ] array), the é character is sorted (and compared) as the e character... But it does not work ! WHY ? Obviously, there is something that I don't understand, but what ? What can I do ? What should I do to obtain that the queries are insensitive to french characters ? Any help will be appreciated !

Workable solution: writing program to communicate with remote internet MySQL server
Hello All, Just thought I'd report back with what seems to be a simple, elegant solution to my previous inquiry re: writing a program to connect with the MySQL server that powers my internet site from my desktop PC. Yesterday I downloaded the latest release of PHP (ver 4.3.0) and, while reading the announcements and release notes, I noticed that PHP appears to be positioning itself as not only a dynamic environment for web site development (and one amply provided with functionality to connect to MySQL), but also as a serious contender for the local desktop scripting jobs, presumably in response to the growing popularity of packages such as Perl / Python / Ruby / etc for desktop tasks. To this end it appears the PHP team have been developing a command line interface flavour of PHP to complement the popular web server flavour. The CLI flavour appears to run oblivious to your local web server environment and presumably is available even if you don't have Apache / IIS / etc installed or configured to serve PHP pages (though, I must admit I haven't had a chance to test whether this is the case). And the great thing about THAT, from my perspective, is that communicating from my desktop PC to my web site's MySQL server on my host's machines is as simple as: $db = mysql_pconnect(mydomainname.com, myusername, myusernamepassword); In the same script I can easily connect to both my local machine's MySQL server and my host's remote MySQL server, compare recordsets retrieved from both and fire synchronizing update / insert / delete statements in response to any differences. As a bonus, I can fire PHP CLI scripts from my box's task scheduler, so I can write scripts to automatically update my remote server in quiet times of the morning, or hourly and so on. I'd also like to thank the several people who communicated with me off-list re: possible solutions to my list question on this topic. All of your suggested solutions were helpful and appreciated.

Needed: Working VB6 example of DAO DSN LESS connection using MyODBC to MySQL preferably with passthruquery
This message intended for MyODBC questions list.
Hello VB6, MySQL, and DAO developers,
A very simple example of my problem:
Dim ws As Workspace
Dim conn As Connection
Dim str As String
Set ws = DBEngine.CreateWorkspace(testing, , , dbUseODBC)
str = odbc;driver={MySQL ODBC 3.51 Driver}; _
SERVER=localhost; _
DATABASE=test; _
UID=;PWD=;OPTION=3
Set conn = ws.OpenConnection(test, dbDriverNoPrompt, False , str)
'this last line errors with
' -- Run-time error '3146' - ODBC--Call Failed.
'if I use:
' Set conn = ws.OpenConnection(test, dbDriverPrompt, False , str)
'and just select OK on the ODBC Connection Manager
' everything work properly - I can't figure out why.
' Maybe because this turns my connection into a DSN
connection.
I'm using all the latest and gratest installs on a MS WIndows 2000.
Does anyone know OFFICIALLY if the DAO DSN LESS openconnection is
supposed to work or not?
If so, could you please post hyperlink for all to share?
Can anyone please test this OpenConnection on their PC?
Can you get it to work?
If so, Could you please post the working code here for all to share?
Does anyone have DAO DSN LESS openconnection code working?
If so, Could you please post your working code here for all to share?
I'm interested in working/tested/proven code examples.
Also, could someone please point me in the right direction for setting
the passthruquery flag?
Where do I set the flag? MySQL or maybe in the connection settings?
If you don't know what DSN LESS means then please post your question in
another thread.
If you want to discuss ADO over DAO please post your question in another
thread.
Thanks,
Barry G. Sumpter
