[PHP-DB] [plain SQL Problem] Group By
Hi, sorry if this is off topic. I hope you don't mind a plain SQL question here. I know I can do what I want using subqueries (I'm on Oracle9i here), but I would really like to avoid them for performance reasons. Here's my example data: DESC dept NameType - DEPT_ID NUMBER(10) DEPT_NAME VARCHAR2(20) SELECT * FROM dept; DEPT_ID DEPT_NAME --- 1 sales 2 marketing DESC emp Name Type -- EMP_ID NUMBER(10) EMP_DEPT_ID NUMBER(10) EMP_AGE NUMBER(2) EMP_NAME VARCHAR2(20) SELECT * FROM emp; EMP_ID EMP_DEPT_IDEMP_AGE EMP_NAME - --- -- 1 1 32john 2 1 19 mike 3 1 40 alex 4 2 42 norman 5 2 33 jason 6 2 20bert And here's the result I'd like to produce: ??? DEPT_NAME YOUNGEST_AGE YOUNGEST_NAME OLDEST_AGE OLDEST_NAME - - -- --- marketing 20 bert 42 norman sales 19 mike 40alex Here's what I have so far: SELECT D.dept_name, MIN(E1.emp_age) AS YOUNGEST_AGE, MAX(E2.emp_age) AS OLDEST_AGE FROM dept D, emp E1, emp E2 WHERE E1.emp_dept_id = D.dept_id AND E2.emp_dept_id = D.dept_id AND E1.emp_id E2.emp_id GROUP BY D.dept_name DEPT_NAMEYOUNGEST_AGE OLDEST_AGE -- marketing 2042 sales 19 40 What is missing ist the name of the younges and oldest employee, since I can't use aggregate functions to get at them. Any help would be greatly appreciated! Thanks, -sapporo. -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP-DB] hotornot functionality
I am toying with the idea of implementing functionality similar to the hotornot.com site -- for a different purpose, mind you, but the same kind of user experience. Here's what it does: 1. A picture is served up. 2. User clicks on a radio button scale from 1 to 10 to rate the picture. 3. The page refreshes. The rating is re-computed with the user's rating for the original picture. The original picture becomes that last rated pic, and a new one is served up. 4. The user can cycle through as many pictures this way as they want. I have MySQL and PHP to work with. What I am trying to do is figure out the best approach to implementing it. Specifically, when the user clicks on the radio button, that triggers the form submit via JavaScript. The form submit updates the database with the rating and then fetches the next row. The problem that occurred to me as I was putting together a prototype is: I don't want the user to get the entire result set of all the images in the database at once. I really want them to get just the two images (the one they just rated and the one they are about to rate). Is there a way to remember the last row they selected and then use that number to fetch the next one on the subsequent request? I can keep recycling hidden form fields with a number, which should work ok, but the problems come up when they reach the last row. Anyway, just looking to see if you folks have some ideas. I would prefer to roll my own rather than use one of the available hotornot-style PHP scripts to do this. Matthew J.

Re: [PHP-DB] hotornot functionality
Why not have a field called last in the db? You set it equal to true for the last image and then check it for all of the images. If it's true, you just null the next option and the user can't go any farther.

RE: [PHP-DB] hotornot functionality
i would do it totally different if i understand you right.. you start with row number one, show it, give it a rate, then show number 2, and show number 1 as last rated pic!!! then you have the problem of reaching the last record!! but !! i also see another problem: if you do row 1,2,3,4 you always gets the first image , then the second etc etc what I would do: take a random picture from the mysql table (you can use the mysql random functin within a query for it) then show this one! give it a rate then after rating it, put it in an array then do a new random query but use the 'not in' function and don't select the numbers what are in the array!! so you get a new picture! and the last rated pic is the picture at the last place in the array so you can show it... and when the array has equal number of rows as the table has, you showed them all and you empty the array so they can start over you get my point ?

Re: [PHP-DB] hotornot functionality
I think the best way is to use sessions. when the user comes to the site or he submits a rating, start a session and create a variable, in which you store the images' id that the user rated like $var=1,1423,523 etc.. then use it in your query mysql_query(select id from images where id not in ($var) order by rand() limit 1); this will keep the images the user rated out of your recordset and gives you a random image from the database -- Finest, Mengü mailto:[EMAIL PROTECTED] MH I am toying with the idea of implementing functionality similar to the hotornot.com site -- for a different purpose, mind you, but the same kind of user experience.

Then on the next page, you can get the id. Or geez, it's gonna be there
anyway -- after you do the insert/update of your vote, just pass that ID to
the function that displays the page.
function display($x) {

Re: [PHP-DB] hotornot functionality
I agree with both Peter and Mengü, in a manner of speaking. Assuming you want
visitors to return, I think it's best to use sessions and cookies so that
they're not served the same image twice. Passing that information between pages
is easy with Peter's method. Mengü's technique (albeit slightly altered) would
work well at storing that information for future use.
Storing this information is *very* important. If users keep seeing the same
images, they won't return.

Anyway, just looking to see if you folks have some ideas. I would prefer to
roll my own rather than use one of the available hotornot-style PHP scripts to
do this.

Hello!!
If your storing the file name, file type, in mysql; and are storing
the files on a server.
(Which you should be doing!!!)
You could use this!!
//
$query = SELECT * FROM Images WHERE Num = $num;
$result = mysql_query ($query, $db);
$data = mysql_fetch_object($result);
function sendfile($to, $subject, $text, $cc, $from, $file, $type) {
$content = fread(fopen($file,r),filesize($file));
$content = chunk_split(base64_encode($content));
$uid = strtoupper(md5(uniqid(time(;
$name = basename($file);
$text = stripslashes($text);
$subject = stripslashes($subject);
$header = From: $from\nReply-To: $from\n;
$header .= Cc: $cc\n;

[PHP-DB] pg_fetch_result() get unexpectly trimmed
Take a look at the titles in this site (revision project of my bigbands
site):
http://studorg.nlh.no/storband/revisjon/vis.php
An then, move up one folder, and hava look at the same on the current site:
http://studorg.nlh.no/storband/vis.php
To show the database-entries, I use code similar to this one:
--- snip ---
$query = SELECT * FROM nyheter_view WHERE visframside = 't' ORDER BY
endradato DESC;; // listar oppslag for framsida
$resultat = pg_query($dbtilkobling, $query);
if (!$resultat) {
$feilmelding .= $F1101;
include ($exit);
}
$num = pg_num_rows($resultat); // tilordnar antal rekker på spørringa viss
den blei vellukka
$i = 0;
while ($i$num) {
$nyheter_id[$i] = pg_fetch_result($resultat, $i, nyheter_id);
$tittel[$i] = pg_fetch_result($resultat, $i, tittel);
$ingress[$i] = pg_fetch_result($resultat, $i, ingress);
$i++;
}
pg_free_result($resultat); // frigjer resultatet frå spørringa
$i = 0;
while ($i$num) {
if ($tittel[$i]){
echo h3.$tittel[$i]./h3\n;
}
if ($ingress[$i]){
echo p.$ingress[$i].br\n;
}
$i++;
}
--- snip ---
But some of the returning strings like $tittel[$i] get trimmed, and show
only first letter in the string stored in the actual database-cell. The
strange ting is tha $ingress[$i] returns the whole string... So the problems
seem to be in returning values from the column.
The code is copied from the script which queries the same table for the same
data on the second URL. So the data presented should be exactly the same.
I've had a similar problem while developing the current site, but then the
problem got solved, and I can't remeber if I did anything (I guess not). But
then it happened when I printed the result from the oid-query in the
insert-script.
Why do this happen? Is it an postgre-issue, or a php-issue? What can I do to
solve the problem?

Then you should be able to use that function...
So are you storing the Path of the file in MYSQL or any other
database?!?!!?
If not then replace
/-
$file2 = (./images/$data-name);
//--
to reflect your path...

Re[2]: [PHP-DB] connection pooling
of course I did, let me tell you how apache and php interact with php as far as I know: I'm using php set up as a module for apache. so apache handles each web page request and forwards the request to one of its threads (the thread count is set up from httpd.conf). the algorythm it uses is pretty much the same I described before If there is an idle thread, hand the request to that thread, else create a new thread So, each thread creates a persistent connection to mysql, regardless of the connections created by the other threads. Which at the end, comes to 'a persistent connection for every thread' and this, I don't find very effective. what I want to do is, get between apache and mysql, and handle every connection request with a resource dispenser. regardless of the thread count, I want my dispenser handles connection requests in the way apache handles web page requests: If there is an idle connection, use it. else create a new connection -- Finest, Mengü mailto:[EMAIL PROTECTED] JG Did you read the manual page?

[PHP-DB] Multiple inserts revisited
The subject would lead you to believe that this is a check the archives post.
Worry not, I already did. Besides, this is more informative than anything.
I'm working on a catalogue (menu, really) admin page from which a client will
set their daily specials. My design calls for the user to select the day's
special items (already in the DB) with checkboxes. Submitting the form will set
the selected items as the day's specials by inserting the item_id and date into
another table. (This is done so that previous specials may be recalled later.
I don't see a need for it but the client requested the feature).
Regardless whether the items are inserted or simply updated, I was stuck on how
best to perform the operation. My initial thought was to create an array of the
selected items and loop through it to insert or update the various items.
However, I don't like running nearly a dozen queries to perform the operation,
something this would entail.
My other option, as I saw it, was to loop through the items, appending value
data to the query text with each iteration. If that seems cryptic, here's a
basic idea of what I mean.
?
$query = INSERT INTO specials VALUES (
foreach ( $specials as $item ) {
$query = substr_replace( $query, $item., , strlen( $query ) );
}
$query = substr_replace( $query, ), strlen( $query )-2 );
?
If $specials was an array with the values spec1, spec2, and spec3, the final
value of $query would be:
INSERT INTO specials VALUES (spec1, spec2, spec3)
This provides precisely what I need and reduces things to one query. Let it be
noted that the actual script would be a bit more complex (associative arrays)
but the general structure is there.
I know that there have been a few multiple insert questions posted to the list
lately so perhaps this will prove helpful to those who asked. If not, than
perhaps some of you can point out flaws in my design, should there be any.
Thanks for your time.

[PHP-DB] Operation must use an updateable query
I am using PHP 4.2.3 on a Window 2K Pro box with Service Pack 3 installed.
I am trying to access an MS Access 2000 database through the MS Access ODBC
driver. When I try to write to a table, using an INSERT INTO command (see
below) I get the following error:
Operation must use an updateable query
The SQL statement that I am trying to odbc_exec is as follows:
INSERT INTO testtab ([user_name],[subject],[comment]) VALUES ('chad','test
data','Comment x')
This works when I run it as a query in MS Access, and I've been able to get
info from the database using SELECT statements.
I'm just not sure what the Operation must us and updatable query means.
I actually found the same error in the help files for MS Access and this is
what it says, but to me it is just as unintelligible as the message:
This error occurs when the current query's Update To row includes a field
from either a crosstab query or select query in which an aggregate (total)
was calculated for the field (using either the Totals row or a domain
function in the Field row). To update a field using the aggregate of another
field, calculate the aggregate in the update query itself, not a different
query.

copy($userfile, $HTTP_POST_FILES['userfile']['name']);
} else {
echo error. File: '$userfile'.;
}
$filename=$HTTP_POST_FILES['userfile']['name'];

Basically the file is not recognize as local, i have no idea why, the file I sent was
C:\\ based
This is another code that I have tried
?
$userfile = C:\\joey lim.jpg;
$UPLOAD = fopen( $userfile, r );
$contents = fread( $UPLOAD,filesize($userfile));
fclose( $UPLOAD );
$SAVEFILE = fopen(upload//.$userfile_name, wb );
fwrite( $SAVEFILE, $contents,$userfile_size);
fclose( $SAVEFILE );
echo Server HaD Receive the Upload Files!;

Re: [PHP-DB] Firebird PHP Module (Repost)

Anybody has Firebird 1.5 an php working properly in linux? Hi Julian, may be you have already solved for you own, if so the following could be helpful for everyone else who have such a problem. I have just read a post form Edwin Pratomo having same problem with Perl and he's right. Look in your syslog and you will find +/- the same thing: Finally caught the culprit in the syslog: perl5.9.0: Missing configuration file: /home/edwin/bleedperl/firebird.conf, exiting (No such file or directory) looking for firebird.conf in the wrong place. This seems to be a bug in 1.5 RC2, which is no longer exist in RC3. we can enjoy Firebird-1.5rc2 with php on Linux too ;) Daniela -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP-DB] Operation must use an updateable query
Hi Chad
Make sure the webserver has write permissions on the Access database file.

I am using PHP 4.2.3 on a Window 2K Pro box with Service Pack 3 installed.
I am trying to access an MS Access 2000 database through the MS Access ODBC

below) I get the following error:
Operation must use an updateable query
The SQL statement that I am trying to odbc_exec is as follows:
INSERT INTO testtab ([user_name],[subject],[comment]) VALUES ('chad','test
data','Comment x')
This works when I run it as a query in MS Access, and I've been able to get
info from the database using SELECT statements.
I'm just not sure what the Operation must us and updatable query means.
I actually found the same error in the help files for MS Access and this is
what it says, but to me it is just as unintelligible as the message:
This error occurs when the current query's Update To row includes a field
from either a crosstab query or select query in which an aggregate (total)
was calculated for the field (using either the Totals row or a domain
function in the Field row). To update a field using the aggregate of another
field, calculate the aggregate in the update query itself, not a different
query.

RE: [PHP-DB] Multiple inserts revisited
-Original Message-

My other option, as I saw it, was to loop through the items,
appending value
data to the query text with each iteration. If that seems
cryptic, here's a
basic idea of what I mean.
?
$query = INSERT INTO specials VALUES (
foreach ( $specials as $item ) {
$query = substr_replace( $query, $item., , strlen( $query ) );
}
$query = substr_replace( $query, ), strlen( $query )-2 );
?
If $specials was an array with the values spec1, spec2, and
spec3, the final
value of $query would be:
INSERT INTO specials VALUES (spec1, spec2, spec3)
I'm actually slightly dubious that this query *does* do what you want, but if you've
double-checked it and it does, then this is a somewhat more compact way of producing
it:
$query = INSERT INTO specials VALUES ( . implode(',', $specials) . ')'
Cheers!
Mike

Do you know anything like the connection pooling system of asp?

What I want is, something that does this: If there is no existing connection or the existing connection is in use, open another persistent connection. if there is an open connection and it's idle, use that one ML Try SQLRelay.
