Re: [PHP-DB] Big speed problem with MySQL
Ok I found what was the main source of slowlyness in my application : awful coding I made, which make several thousands of useless big queries !!! So I am optimizing my system. Nevertheless, I am new to DB cogin, so could you tell me more on Indexes ? What do they do ? Do they really incease speed on great tables ? How do I set or create them ? Thanks for your answers ... Miles Thompson [EMAIL PROTECTED] a écrit dans le message de news: [EMAIL PROTECTED] How are you fetching the data? Do you have indexes on the key fields used in queries? Are you doing the work in SQL or sorting /rearranging a lot of arrays? There are many possibilities for slowness, but you have to tell us what you're doing.

Everything seems ok, but when I do accesses to my DB, it is very slow ! For example, I am able to download the csv file for a specified account (that is not the problem). If I download a dumb file generated by random text by PHP, the transfer rate (on my LAN) is fast 50Kb/s (for example). But if this file is generated by PHP from data collected in MySQL (which base is on the same PC than PHP webserver) then the transfer rate is less than 3.5Kb/s!!! I don't know what to do ... The consequence of that is that the PHP programs are stopped because of script timeout. Anyone has an idea to save me ?

Re: [PHP-DB] finding ID's
Ok Jonathan, [I've put the answer back on the list - there are others who can help, and may well get back to you faster than I] Ok I get the auto_increment stuff... Just one more question. Let's say I want to show 25 rows per page. I want the script to generate links to the next page, and so on. How do I make it show from the highest ID to 25 rows down? There is no auto_decrement Here's an example: ID 1 4 5 8 10 11 12 15 17 18 I want to show the 5 newest rows (have the highest ID's). AUTO_INCREMENT (and your 'AUTO_DECREMENT) only has relevance when a row is being added to the table. When a SELECT is performed, the value is returned, fixed, and numeric, just as if it were any other integer and/or one that you had loaded as a literal value. It does not have any effect on SELECTs. Thus if you SELECT * FROM tblNm, you will not necessarily retrieve the rows in ascending sequence of the id field! Did you already realise this? To retrieve the data 'in order' you will need to add an extra clause: SELECT * FROM tblNm ORDER BY id; That said, perhaps you have two questions here: - sequence the results of a SELECT in inverse order to the AUTO_INCREMENT/id field value by using the ORDER BY id DESC. [RTFM: 3.3.4.4 Sorting Rows] BTW Chapter 3 of the manual is a useful tutorial/user guide that covers many of these topics/offers a functional introduction. - how can a long resultset be split up and displayed on several web pages using a PREV/NEXT page link facility? This answer revolves around the LIMIT clause [RTFM: 6.4.1 SELECT Syntax] SELECT select_expression,... [LIMIT [offset,] rows] The first page is populated with a query saying LIMIT 0, 25, and the next LIMIT 25, 50 (or that 24 and 49?) BTW I was working off your earlier quote of 25 cf the later of 5 This combination of HTML, PHP, and MySQL is not discussed in the MySQL manual, but there are a number of tutorial articles available on the various PHP support sites. If you need to get started/make contacts, visit the MySQL and/or PHP home pages and follow their links, or Google-it. There are also some prepared classes/scripts available for the downloading which will save you the coding time (unless you want to learn for yourself). You will also find this in any book covering PHP and MySQL - a most worthwhile investment if you're going to 'walk amongst us' for a while! Regards, =dn (comments interposed, below) Try using something like $getlist = mysql_query(SELECT id FROM yourdb,$dbconnectetc); $numrows = mysql_num_rows($getlist); echo $numrows\n; This will give you the number of records in your db. If you use autoincrement for the id field your will not have to worry about your ++. If you delete any records numrows will always be correct. =this is correct, but COUNT(*) is optimised/more efficient (RTFM: 6.3.7 Functions for Use with GROUP BY Clauses) First off, sorry for the newbie question... :(. I want to be able to query the database and find the record with the highest ID value. Example... each row ideally has an incremented integer ID (1, 2, 3, 4...) but I am running into problems when I try and delete a row (let's say row 2). My PHP currently selects all of the rows and formulates the ID off of that... This I found out is bad because when I delete row 2 the query says there are 3 rows so my PHP will try to make the ID = 4. I just need the code to find the highest ID so I can ++ it. Sorry again for the easy question! =no need to apologise, we all have to start somewhere. =It is an FAQ. By asking it you indicate that you don't (yet) understand the philosophy of the AUTO_INCREMENT facility. It is there to provide an ID for new rows of data, not to be a 'count' of the rows. If you consider that this ID may be used as a key into this table's data from another table (foreign key), then you will realise that changing ID values to reflect intermediate deletions is less than logical. (RTFM: 3.5.9 Using AUTO_INCREMENT, although it doesn't seem to get into this point - the annotated comments are worth a read though). I've just a had a quick look to see where the manual discusses the 'philosophy' and have come up empty - perhaps someone else can steer you right, if you need more. =It is worth reading through PHP's large collection of built-in MySQL_ functions. There are specific functions that will return various 'numbers of rows' to the script to suit various situations. -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP-DB] Session confusion :-(
I presume that the session is not updating because PHP does not automatically overwrite session variables. You should use something like this: $category = $HTTP_GET_VARS[category]; session_register(category); Session register can be called more than once, and has no effect on current session variables with the same name. See if that works, and if it doesn't have a look at this... http://www.php.net/manual/en/language.variables.predefined.php Adam -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

You could use this script:
?php
$columns = 3;
$count = 0;
while ($query_data = $yoursearch){
$count++;
if ($count $columns)
{
echo td$query_data[]/td;
}
else if ($count == $columns)
{
$count = 0;
echo trtd$query_data[]/td;
}
for ($i=$count;$i=$columns;$i++){
echo tdnbsp;/td;
}
echo /tr;
}
?
I think it works.

[PHP-DB] RE: I cant get the logic for this...
Firstly thanks to everyone who have supplied various way to implement
the issue I was having.
Unfortunately I cant seem to get any one of them to function correctly
I have included my code to see if someone can help adjusting it.
I think I am going wrong in where I am putting the count var.
You may notice I am using the var $v1list. this is so I can display the
output in suitable place on screen.
The code I have included makes my 7 selected items go straight across
the page(obviously) hence the need to
Block it of with some kind of count function.
Thank you for any help or advice

I tried creating a db using a php script and then selecting it and got
the
same problem.
I'm new on Linux so it might be something in the configuration which
needs
working on.
Any suggestions?
Well, if you had posted some code, someone might have seen the error...
:(
Anyway, here is how i do it:
if($db = mysql_pconnect($dbhost, $dbuser, $dbpasswd)){
mysql_select_db($dbname, $db);
} else {
echo mysql_error();
exit;
}

Re: [PHP-DB] Problem connecting to db on Linux
Greg, et al,
Now the re-installation is complete, I am getting past the original error --
only to hit another.
My query is as follows (echoed to web page):
SELECT DISTINCT Nickname, HEI_ID FROM customers WHERE Nickname '' ORDER
BY Nickname
I have checked case against db an it is correct. Am I missing something else
which is obvious?

Do you have your error messages crossed? I ask, because I would think
your
cannot select message would go with your mysql_select_db() and your

Rick,
I snipped the code from my windoze system. I did have to change the case
of
the dbname to reflect the Linux version (all lc).
The error message I got (not displayed on screen but visible on 'view
source') was 'Could not connect' which, to me means that it got past the
login to server and stalled on the select db part?

Oggetto: [PHP-DB] RE: I cant get the logic for this...
Firstly thanks to everyone who have supplied various way to implement
the issue I was having.
Unfortunately I cant seem to get any one of them to function correctly
I have included my code to see if someone can help adjusting it.
I think I am going wrong in where I am putting the count var.
You may notice I am using the var $v1list. this is so I can display the
output in suitable place on screen.
The code I have included makes my 7 selected items go straight across
the page(obviously) hence the need to
Block it of with some kind of count function.
Thank you for any help or advice

RE: [PHP-DB] Problem connecting to db on Linux
so, you probably have something like, right? If not, change your code to:
$query = SELECT DISTINCT Nickname, HEI_ID FROM customers WHERE Nickname
ORDER BY Nickname;
$result = mysql_query($query) or die(error: .mysql_error());
show us your code.
I ask, because you appear to have an extra in fron of ORDER BY

Re: [PHP-DB] cron job
Hi Jen,
Remove the WHERE clause (in your code: WHERE uid={$session[uid]}) in
your query and that will update all rows in the table.
Hope that helps,

[PHP-DB] Dynamic Table Columns
I have a form (criteria.php) that includes two drop down lists from which a
user can select a start period and an end period from a MySQL table. This
form posts to a form called order_summary.php on which I am using the
$start_period and $end_period variables from the criteria.php form to pull
data from another MySQL table which will produce a summary of sales for
those periods as illustrated by the following example:
$start_period $end_period$total
-
Order Type | APR-00| MAY-00| Total |
-
Widget 1 | $100 | $200 | $300 |
Widget 2 | $300 | $200 | $500 |
.
.
.
OK. Fine and good. I have this working. My problem is this:
How can I create a table which will dynamically adjust the number of columns
based on the users request. That is, if the user requests APR-00 through
MAY-00, the table will be built as illustrated above. If the user requests
JAN-01 through JUN-00, the table will be built as illustrated below:
$start_period through
$end_period
--
Order Type | JAN-01| FEB-01| MAR-01| APR-01|
MAY-01 | JUN-01|Total |
--
Widget 1 | $100 | $200 | $300 | $300 | $300 | $300 | $300 |
Widget 2 | $300 | $200 | $500 | $300 | $300 | $300 | $300 |
.

.
I have posted order_summary.php below.
Any thoughts?

Re: [PHP-DB] Semi-newbie - postgres polygon/points and PHP?
sorry the late reply,
could you consider having each set of coordinates in 2 different fields?
select r.x, r.y from room r

Subject: [PHP-DB] Semi-newbie - postgres polygon/points and PHP?
Ok, a kinda newbie question. I set up a Postgres DB with a table that had
a
Point and a Polygon in it (to hold XY and shape settings for munging a
jpeg
image in php).
I could not easily figure out how to extract the data into a reasonably
easy
to use format in PHP. The best I could do seemed like it was extracted
into a string, and then I had to parse that.
While this works, it seems like a BIG hack to me, and the docs have been
less then forthcoming.
I've also tried the usual google search of php postgres polygon to see
if
I could get an idea.
For example, I stored the Point as:(432, 120)
And I got (432, 120) as a string, and had to parse it:
...
$Q = SELECT * FROM room WHERE id=$id;
if(!($Result = pg_exec($Connection, $Q)))
{
print(Query failed $Q);
print(pg_errormessage($Connection));
print(BR\n);
exit;
}
$myroom = pg_fetch_array($Result, $i);
$xy = $myroom[xy];
$xyar = split([\(,\)], $xy);
$x = $xyar[1];
$y = $xyar[2];
...
Any ideas?

Re: [PHP-DB] Dynamic Table Columns
Randy,
Suggest pulling the data out of the resultset using a numberically-indexed array. Then
o/p each TD.../TD
inside a loop - you know how many times to loop, because that is set by the number of
rows (plus Total column).
BTW if you use aliases on those SUM() columns - it will make life a lot easier when
you are using associative
arrays to post-process the data.
Regards,
=dn
I have a form (criteria.php) that includes two drop down lists from which a
user can select a start period and an end period from a MySQL table. This
form posts to a form called order_summary.php on which I am using the
$start_period and $end_period variables from the criteria.php form to pull
data from another MySQL table which will produce a summary of sales for
those periods as illustrated by the following example:
$start_period $end_period $total
-
Order Type | APR-00 | MAY-00 | Total |
-
Widget 1 | $100 | $200 | $300 |
Widget 2 | $300 | $200 | $500 |
.
.
.
OK. Fine and good. I have this working. My problem is this:
How can I create a table which will dynamically adjust the number of columns
based on the users request. That is, if the user requests APR-00 through
MAY-00, the table will be built as illustrated above. If the user requests
JAN-01 through JUN-00, the table will be built as illustrated below:
$start_period through
$end_period
--
Order Type | JAN-01 | FEB-01 | MAR-01 | APR-01 |
MAY-01 | JUN-01 |Total |
--
Widget 1 | $100 | $200 | $300 | $300 | $300 | $300 | $300 |
Widget 2 | $300 | $200 | $500 | $300 | $300 | $300 | $300 |
.
.
.
I have posted order_summary.php below.
Any thoughts?
Thanks,
Randy Rankin

RE: [PHP-DB] sql query
try replacing

with
WHERE display='$custcatergory');
and also tru echoing the value of that SQL statement (assign it to a var
first) to make sure you are getting the right thing.

[PHP-DB] How to make logout from database server (ORACLE for example) when user closes its session
Hi all Is it possible to track such situations when http user closes connection to HTTP server to close opened persistent connections to the database? This connections is still active all the time (if using php not as CGI but as module for Apache) and when user trying to login next time PHP uses previously opened (by OCIPLogin for example) persistent connection (the same connection resource) - but this connection may be broken from the server side if its idle time is too long. So I found only way to restart my Apache + modphp from time to time. :( Thanks, Vlad -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
