Re: Math Computations
I agree with the suggestion below strip the character and typecast it if
necessary. In JSP I think you can convert it to a number and then typecast it.
In PHP, I think the principles might be the same.
In addition, it might be a good idea to restrict the columns that require
computation to a numeric value rather than a string because you can always add
the comma later when totalling it for display. It might also be more efficient
for sorting and doing sums, totals etc from your select statements.(i.e. select
sum() total()) since computers are inherently better at handling numbers than
strings (though I could be mistaken)
So if its possible for you to redeclare the table definition then that will be
great.
Good luck

Re: Encrpt/Decrypt
Just want to add a few more things here that might spark your brain cells. All in all I agree with the suggestions presented. Use an encrypt function in your code, for something simple I've created a very basic encryption function in perl using Crypt::Blowfish modules and then I have control of the key to encrypt and decrypt it. Then you can process your request over SSL (if possible) just run the script over https if supported and then store the encrypted value in the database as a string. I think you can even run SSL on MySQL so that you can secure your connections further especially if you're replication your database etc. The MD5() function in PHP might also do the trick for you. http://www.php.net/manual/en/function.md5.php Good luck JM Gregory Junker wrote: > and it's all-around better to encrypt the password BEFORE you transmit > it over an unsecure connection, or even between processes on a > potentially unsecure machine.

Re: [MANY to MANY] relationship with MySQL ???
I guess You could write Your query with JOIN statements to
to get all information by one single query, not having to store
things in PHP arrays.
a simpe one could look like this...
/* depending on what criteria is beeing used */
$match = "artist.name = $submitted_artist";
$match = "songs.name = $submitted_song";
/* axs = artists_x_songs */
$SQL = "SELECT artists.name, songs.name FROM artists, songs, axs WHERE ";
$SQL .= "artists.id=axs.artist AND songs.id=axs.song AND $match";
I'm sorry but I haven't time to test this in practice but i'm 97% that it
works... ofcource You have to modify the query to match Your DB layout

'Ang on - I'm not a PHP man so I've got to think my way through the

we're starting with a song, the steps are:
1) Grab the song ID (primary key) from the songs table.
2) Select all the Artist IDs from the song_x_artist (x-reference) table
and push them into an array. (This is why we want sub-selects in MySQL 4!)
3) Pop each value from the array and use it as the criterion to select
all the details that you want from the artists table - what comes back

So, yes, what you've done looks right. Only one way to find out ;-)

Re: Math Computations
Hi All,
How do I make calculations in php or mysql if the value has a comma like
2,000 + 32,000 = 34,000. I have a problem
calculating if one of my values has a comma. It doesn't display the right
output. I'll appreciate anyone who can
help me with this.
Thanks.
Delz.

Like most other password functions you'll find in the unix world mysql's password function doesn't 'encrypt' a string, it generates a one way hash. Meaning that there's nothing unique to decrypt; there may be multiple strings which produce the same hash but the likelyhood of any two strings (even very similar strings) generating the same hash is microscopic. But in the context you're raising the answer is "there isn't one". -- TWZ +-+ | Copyright 2001 by Terrence W. Zellers.

Re: [MANY to MANY] relationship with MySQL ???

How does song_x_artist reference the other databases? Is there a way to set
up a field to always be a reference to another table?
I am not quite sure what you mean... but here is my take anyways. Is this
going around my elbow? Or is this just how you do relationals in SQL?
(For each relationship you may want to have in a system, you must set up a
table to house that relationship?)
Table::"song_x_artist"
*
PrimID (can't duplicate)
SongID (can duplicate)
ArtistID (can duplicate)
(PHP) & MySQL
*
$songID = (the id of the song the user selected to sample)
$artistsOnSong = Select * from "song_x_artist" where "songID" = $songID
while ($artistArray= mySQL_Fetch_Array ($artistsOnSong)){
$currentArtists = Select * from "Artists" where artistID =
$artistArray[ArtistID]
while ($artistInfo= mySQL_Fetch_Array ($currentArtists)){
//start to build the html table of the related artists for the song
here.
}
}
Would that work? And if it does... I am not so sure about how to write it
out, so if you have any suggestions on better syntax, please advise.
Thanks
Robbie

Re: [MANY to MANY] relationship with MySQL ???
This is the classic case for a junction table (aka bridge table, associative table). It sits between Artists and Songs; let's call it PlaysOn. Artists: ArtistID: autoincrement ArtistName: varchar DOB: date etc. Songs: SongID: autoincrement SongName: varchar Duration: in seconds, say etc. PlaysOn: SongID: FK into Songs ArtistID: FK into Artists Given this structure you can: a) add any number of players to a song; b) select any song and all its players; c) select any player and all the songs she played on; d) select a song title and see all the versions you have; e) add another layer atop this called Recordings without disturbing anything beneath (now the same song by the same artist(s) can appear on multiple recordings). You could add a ComposerID (FK into Artists) to the Songs table, but that corners you because what do you do about Lennon & McCartney, Rogers & Hammerstein and so on? To go to that level of detail you need another bridge table, SongComposers: SongComposers: SongComposerID: autoincrement SongID: FK into Songs ArtistID: FK into Artists With this table, you could add to the list of selects with a union that grabs any song Artist 123 either played on or helped compose. hth, Arthur - Original Message - From: "Robbie Newton" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Wednesday, April 17, 2002 10:25 PM Subject: [MANY to MANY] relationship with MySQL ??? > Hello all, > > [~~I guess I could do something like MySQL>select FROM "Songs" where > "artists" contains $currentArtist~~] > > I have a sampling section on a site that I am working on and am trying to > find out how to display a table of the artists featured in that song.

Re: [MANY to MANY] relationship with MySQL ???
Hi Robbie, all I have lots of things that need many to many - the way that I do it is this: create table artists ( a_ser int unsigned not null primary key auto_increment, artist_name varchar(64), other stuff... ); create table songs ( s_ser int unsigned not null primary key auto_increment, song_title varchar(64), more other stuff... ); create table song_x_artist ( a_ser int unsigned not null, s_ser int unsigned not null ); ...So the table song_x_artist contains references to all artists in a song and vice-versa. (Field names correspond between tables.) Hope this helps - let me know if not clear. It works for me...

Replication Oddity
Hi I am running MySQL 3.23.49a, installed from the "official" RPMs. The master is on a (Linux) machine with a permanent Internet connection and an routeable IP address. The slave is at another location with a *nearly* permanent Internet connection, behind a masquerading firewall. Due to restrictions on ISP firewalls, I have set the MySQL port on both machines to be a non-standard 119 - this is normally the NNTP port, but I have NNTP commented out in inetd.conf to free the port up. What I am finding puzzling is that replication is only working some of the time. There are no errors occuring in the error logs at either end. Master and slave stati show the same position. If I make a change on the master, the slave position always changes to match. *However*, the data on the slave does not necessarily change! All the transactions are updates and they have been tested in char and text fields on two different tables. Sufficient to say, this all worked fine when I tried it out in the lab (two machines on same LAN). Has anyone seen anything like this before, or can they give me any pointers as to what might be happening?

[MANY to MANY] relationship with MySQL ???
Hello all, [~~I guess I could do something like MySQL>select FROM "Songs" where "artists" contains $currentArtist~~] I have a sampling section on a site that I am working on and am trying to find out how to display a table of the artists featured in that song. The sample section works as follows: Go to the samples page and choose an album to sample. Returns the list of song names that result from the album you chose click on one of the song names to open a new window with the shockwave file that streams the song. The client has asked me to add the (one or many) artists featured in that song in the window that loads up. I am not sure how to set this up. It would be a many to many relationship I think... (one given artist could be featured on many different songs) [many] to (one given song could have many featured artists) [many] My first thout of how to set this up is to just enter comma delimited data into a field in the song database called, "artists". But when I query it I don't know how I could make that work. I guess I could do something like MySQL>select FROM "Songs" where "artists" contains $currentArtist< Would that work? Is there a such thing as "contains". (kinda new to SQL).

Check to make sure your table type is *really* InnoDB.
MySQL doesn't necessarily have the transactional table handlers
enabled (for example, if it's not a MySQL-Max binary distribution,
or if you compiled it from source but didn't specify --with-innodb).
In such cases, you can specify TYPE=InnoDB in the CREATE TABLE
statement, but MySQL will silently create the table as MyISAM.
Use SHOW CREATE TABLE tbl_name to see what its type is.

myodbc ihtml unknow database
Hello all, I'm running mysql 3.23.44-1, myodbc 2.50.39 compiled with --with-unixODBC", and unixodbc 2.0.7-3, and iHTML. mysql and unixodbc were installed via rpm. All running on the same RedHat 7.2 box. I have set up the necessary system dsn's in /etc/odbc.ini and made sure that all driver files are where they are supposed to be. I can successfully connect to the dbase using isql and the system dsn name from the command line and perform sql queries from isql. And to be sure, I tested using user dsn's as well, they work fine. iHTML on the other hand keeps getting "[unixODBC][TCX][MyODBC] unknown database "dbase-name". I have checked the datasource that the ihtml system is using and the dbase name and user name are correct. I have also inserted user dsn files (.odbc.ini) in places where I thought they might be seen... in the /usr/ihtml directory and under the admin directory of the ihtml system. Nothing, however, seems to work. If anyone can help me figure this out I would greatly appreciate it. If you need more info or example dsn's let me know.

InnoDB or BDB & ON DELETE RESTRICT
If I create a table like this: CREATE TABLE depts ( ID Int AUTO_INCREMENT PRIMARY KEY, name VARCHAR(30) ) TYPE=InnoDB; I add three Records to this table. THen I create this other table: CREATE TABLE employees( ID INT AUTO_INCREMENT PRIMARY KEY, name varchar(20), dept_id INT, FOREIGN KEY (dept_id) REFERENCES depts(ID) ON DELETE RESTRICT ) TYPE=InnoDB; Then I add 2 records to this table, one with value 1 on dept_id field and the other with value 2. I want: If I attempt to delete Record with ID 1 on table depts, that MySQL don't allows me to do so, or that it updates the records at table employees to be deleted or updated to value 2 on the field dept_id. i have InnoDB and BDB working on the System, but I don't know how to do this, every time I delete from table depts, nothing happens at the records at table employees, no warnings, no nothing.

RE: print on top
Hi Jule,
You need to sort your records with "ORDER BY" clause . I don't know what
your table looks like and obviously don't know if you have suitable columd
for it.. Say you have a newsid field defined with int datatype with
auto_increment property, then you can issue your statement as "SELECT ..
FROM table ORDER BY newsid DESC" to make the last inserted row at the very
top. Likewise, if you have a inserted date/time column to keep track of the
times that news are inserted , it may be used for the same purpose as well.

RE: One field or numerous datatype-specific tables?
Howdy - Am I missing something? Why would you have to create all of your columns as BIGINT? Whether the "has pool" column is a TINYINT, BIGINT, or whatever, the SELECT statement would be the same, wouldn't it? Won't "SELECT FROM HOMES WHERE HasPool = 1;" return houses with pools regardless of the underlying column type for HasPool? Even if you absolutely have to create the HasPool column as a BIGINT, you waste 7 bytes. Unless you are talking about a database of all houses in North America, I would really rethink worrying about the wasted space, anyhow. Especially versus the complexity of a multiple table solution.

I am having a problem determining the best SQL DB schema to use. I have a table which stores attributes on homes, attributes such as "square footage", "price", or "includes pool". Now the problem I am having is how to store the actual value of the attributes. An attribute like "square footage" or "price" can simply be stored as a BIGINT. However, an attribute like "includes pool" is a boolean and I don't want to make a bloated table by storing a 1 or 0 in a BIGINT field. Plan 1 CREATE TABLE homes (id BIGINT UNSIGNED not null , fkey_attrib BIGINT UNSIGNED not null , value BIGINT UNSIGNED not null , PRIMARY KEY (id), INDEX (id), UNIQUE (id)) Let's say I wanted to show all properties that had a price of less than $200,000. Let's say that the price attribute is attribute number "32". I would execute the following: "SELECT id FROM homes WHERE (fkey_attribid=32 && value<20)" Now let's say I wanted to show all properties that had a pool and the "includes pool" attribute was attribute number 12. "SELECT id FROM homes WHERE(fkey_attribid=12 && value=1)" The problem I am having is in defining the field "value".

It just seems like a waste to me, however, to have a BIGINT datatype used for boolean attributes (such as "includes pool"). Plan 2 The alternative I came up with is to make the field "value" be relational. I would create several other tables such as: CREATE TABLE homes (id BIGINT UNSIGNED not null PRIMARY KEY (id), INDEX (id), UNIQUE (id)) CREATE TABLE homes_bigint(id BIGINT UNSIGNED not null , fkey_attrib BIGINT UNSIGNED not null , value BIGINT UNSIGNED not null , fkey_homes BIGINT UNSIGNED, PRIMARY KEY (id), INDEX (id), UNIQUE (id)) CREATE TABLE homes_boolean(id BIGINT UNSIGNED not null , fkey_attrib BIGINT UNSIGNED not null , value TINYINT UNSIGNED not null , fkey_homes BIGINT UNSIGNED, PRIMARY KEY (id), INDEX (id), UNIQUE (id)) Now it would fall on the responsibility of my script (which I am fine with) to determine which attribute pairs up with which table. Let's say I wanted to show all properties that had a price of less than $200,000. Let's say that the price attribute is attribute number "32". I would execute the following: "SELECT id FROM homes AS h LEFT JOIN homes_bigint AS hb ON homes USING hb.fkey_homes=h.id WHERE (hb.fkey_attribid=32 && hb.value<20)" Now let's say I wanted to show all properties that had a pool and the "includes pool" attribute was attribute number 12. "SELECT id FROM homes AS h LEFT JOIN homes_boolean AS hb ON homes USING hb.fkey_homes=h.id WHERE (hb.fkey_attribid=32 && hb.value=1)" So the question I am debating is if I should put everything in just one table (in which case boolean values would be stored in the same field as BIGINT values) or if I should have separate tables that are streamlined to particular datatypes. Would having everything in one table be faster? Or could I simply optimize the numerous datatype-specific tables in plan 2 and be just as fast? - 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 unresponsive ....
Hi all, Last friday we found that mysql was unresponsive (all the SQL activities were on hold) but the daemon was still running. We shutdown the daemon and restarted and everything was OK. My questions: 1) What could cause this behavior ? 2) Is there any way to monitor such a behavior ? any commands, scripts that could test for inactivity etc. Needless to say that I am a newbie on mysql front.

RE: LOOKUP
Hi, Your solution would work if the set of the values you'll get from one table is primary key.. If it is not a primary key, i.e. allowing duplicate values, then everytime there is an insertion to the table you will have to check to see if it is a new-added value or not.

Re: foreign key on update cascade in mysql doesn't work
Hi! The brand-new source prerelease 3.23.50b-pre which you can download from http://www.innodb.com supports ON DELETE CASCADE and ON DELETE SET NULL. But does not support ON UPDATE CASCADE. Typically a foreign key refers to the primary key of another table, and it is not that common a primary key is updated. Thus I chose to write ON DELETE CASCADE first.

Mysql 4.0.1 crashing in fulltext search with some words..
I'm not sure if this has been reported earlier, but my mysql-server goes
down if I run a query with two 'match against' where one of them
contains/matches the word 'think'...
It terminates after the first query, but when I change the word 'think' to
'excel' or any other word it works flawlessy. I have written the queries
like this since '... against ('+windows +excel' IN BOOLEAN MODE)' doesn't
work in the 4.0.1 version of MySQL.
I find this pretty strange
>From mysql consol:
mysql> SELECT count(*) FROM DB_GNIST.varer WHERE MATCH (tittel) AGAINST
('windows' IN BOOLEAN MODE) AND match (tittel) against ('think' IN BOOLEAN
MODE);

Changing international charset for ORDER by sorting
Hi! Anybody knows how can I change the character set, when MySQL is running, to be able to do ORDER BY using international strings? I would need to do this without changing config, while I run my perl script. I would need to do sortings for different languages. So locale definition should be changed right from within MySQL. (changing locale in config is not solution, because I need to change more times for different languages) How it is possible to change character set dynamically, or to set different character sets for different tables within the same database?

C API - intermittent problems with insert
Hello, I'm using the Suse-provided binary of 3.23.47 on Suse7.3 Linux, and I'm having a funny problem with my program, which uses the C API, on this database. The database I'm accessing is using only the BDB table type. The host system is a relatively low powered IBM 300XL, (PII-233, 96MB RAM, 2GB WD EIDE disk). Every so often, (under heavy load?), the database appears to miss an INSERT operation. This happens intermittantly, so is not predicatable. It also doesn't happen very often, (< 1%), but even so it's darned annoying when it does happen (sigh!). Has anyone out there in MySQL land got any ideas on how I can track this down? I was going to enable the ascii log and see if an actual INSERT is being issued, (in which case I've got a MySQL bug) or not (in which case my code is defective in some way - more likely methinks). Any opinions welcomed, and feel free to take this off the list, so as not to annoy everyone else with my stupidity. Regards Bob Cross.

Re: Multiple Inserts
Hi all
Thanks for your replies to my question about multiple updates in one query. I think
Kittiphum Worachat is right in that I have designed it wrong. I couldn't get it to do
what I wanted, so I reverted to single update queries.
cheers
Mark
---
Summary of replies
-- from Paul Wilson
I'd guess that $job_number = 'AA3' or something similar.
To update all 3 records inserted as above, try :
update mytable set jobdate='$job_date' where job_number like 'AA_';
--- from DL Neil
However if you look at the template for the INSERT command notice that
after the VALUES clause there is an ellipsis - something like:
VALUES(expression [,expression]...) [,(expression, etc)...]
thus you can add as many rows' worth of data as you like - each row
within its own set of parentheses:
insert into mytable (id,name,job_number,job_date) values
('1','Mark','AA1','2002-04-15'),
('2','Mark','AA2','2002-04-16'),
('3','Mark','AA3','2002-04-17')
Kittiphum Worachat -
Your problem is misused of form transfer data please notify that by GET
method the data transfer to server with name and equa sign (=) and then
value each data seperate by & so
id=1&name=Mark&job_number=AA1&job_date=2002-5-19
mean the data have 3 elecment id,name and job_date as your data you send 9
element but use the same name so finally it only have 3 element and the
value id the last assign so you will got at last
id=3&name=Mark&job_number=AA3&job_date=2002-5-25
the first and the second set has over write so when you update data you got
the last data (id=3) update only
how to solve this problem you shoul declare the name seperate like this
id1=1&name1=Mark&job_number1=AA1&job_date1=2002-5-19
&id2=2&name2=Mark&job_number2=AA2&job_date2=2002-5-21
&id3=3&name3=Mark&job_number3=AA3&job_date3=2002-5-25
and update 3 time
$sql = "UPDATE mytable set job_date='$job_date1' where job_number
='$job_number1'";
@mysql_query($sql, $connection) or die.;
$sql = "UPDATE mytable set job_date='$job_date2' where job_number
='$job_number2'";
@mysql_query($sql, $connection) or die.;
$sql = "UPDATE mytable set job_date='$job_date3' where job_number
='$job_number3'";
@mysql_query($sql, $connection) or die.;
Original question --
That the thing see, the form(using GET instead of POST) sends data with
the new dates like this:-
id=1&name=Mark&job_number=AA1&job_date=2002-5-19
&id=2&name=Mark&job_number=AA2&job_date=2002-5-21
&id=3&name=Mark&job_number=AA3&job_date=2002-5-25
and the UPDATE query like this:-
> $sql = "UPDATE mytable set job_date='$job_date' where job_number
> ='$job_number'";
> $result = @mysql_query($sql, $connection) or die.;
just updates the last record.
Can the query be written so that it updates each of the three records?

Re: Problem with query
Depends on how the fee paymnents are defined. At its simplest: SELECT Members..Name FROM Members WHERE NOT(Members.MemberID = FEE_PAYMENTS.MenmbersID) would select members that have no fee payment records. You could build on it from there...

Problem with query
I am having a small problem with a small mysql query... I want to make a list of: "WHO HAS NOT PAID THEIR MEMBERSHIP FEE". I guess I could maybe solve this one myself, its not too hard ... I have one table with members MEMBERS -- | MemberID | Name | etc. One table with fee payments FEE_PAYMENTS -- | MemberID | date | price | etc... Now: How would I make a query that would list all members that have not paid their fee? How would I make a query that would list all members that have paid their fee? I'm just too tired to think it out myself :) Forgive me :) - Med vennlig hilsen, Torkil Johnsen [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?

LOOKUP
Dear Group, Could anyone help me please, I want to create an ENUM column in one table that lists the entries in another table. For example, the sales table to have a "staff" column that automatically gives a choice of the names of all staff listed in the staff table. I have been told that Access has a data type that does this called lookup, but I only want to use MySQL. I couldn't locate the answer in the manual and I'd appreciate it if someone can explain how this can be achieved / worked around. many thanks Simon T - 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?
