[PHP-DB] Mysql MaxDB Support?
Does PHP natively support MaxDB? I have not seen any mention of it in the manual anywhere. If not and anybody uses ODBC could you kindly post the configuration? Cheers! -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP-DB] Mysql MaxDB Support?
MaxDB is based on sapdb, try searching for that you probably get better results because sapdb is older that maxdb. In the near future maxdb will support the mysql protocol, so i guess you could then use the mysql functions with maxdb. - Original Message - From: Carolyn Longfoot [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Thursday, March 11, 2004 8:57 AM Subject: [PHP-DB] Mysql MaxDB Support?

[PHP-DB] Pulldown value not passed to next page
What is wrong with this picture? I build a pulldown for selecting page size(number of
rows in one page). If page is new, it gives the default (selected) of 15. For some
reason, when Previous/Next are clicked, the value passed is still 15 even though the
pulldown says something else (5 or 15 or whatever). Down below my pulldown code is the
code to call the Next/Previous pages (just the important part)
**

[PHP-DB] Impact of MySQL Queries
I have IIS 4.x and MySQL running on the same machine. So do queries use up bandwidth? Does it matter if I have 20 queries per page? Will that slow it down if many people started using my site? Currently only I, and some friends for testing, use it. -- Marcjon -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP-DB] Pulldown value not passed to next page
Hi Karen,
Depending upon the method used for your form, you should be able to find the value in either $_GET['pagesize'] or $_POST['pagesize'].
hth,

RE: [PHP-DB] Pulldown value not passed to next page
Karen,
I'm assuming that when you say:
For some reason,
when Previous/Next are clicked, the value passed is still 15
even though the pulldown says something else (5 or 15 or
whatever)
you're drawing that conclusion because 15 images (or whatever) are displayed
on the resulting page regardless of what you select in the pulldown. Does
the actual URL say 15 or does it say something else (e.g. 20)?
If the URL shows that pagesize=15, but the resulting page displays 20
images, it's possible the problem is that you're not checking the actual
value passed in the URL.
Your current code:
If(!$pagesize)
{
$pagesize=15;
}
Should read:
If(!$_GET[pagesize]){
$pagesize=15;
}
Else{
$pagesize = $_GET[pagesize];
}
This is assuming that you have register globals turned off (I think that's
right). Because, otherwise, each time the page loads with your current code,
$pagesize would never be set and would always default to 15.
Hope this helps.
Rich

Re: [PHP-DB] Impact of MySQL Queries
Think of bandwidth as the volume of data returned by the web server to the browser, not machine cycles. MySQL will use machine cycles, but there's more to it than that. For fastest response the fields you are running the query against should be indexed. What pushes you to 20 queries per page? That seems a little excessive, as each of those is a hit to the database. Are the fields indexed? Are they cascading queries, the second depending on results returned by the first, the third upon the second, and so forth? Could you handle your returned result set by getting more data and grouping it? More information is needed to answer your question properly.

Re: [PHP-DB] Impact of MySQL Queries
If both services are running on the same machine then no, the number of queries per page will not affect bandwidth. It will however, affect you processor usage. Without having seen your code, I can only make generalizations. 20 queries is a bit excessive but it's still manageable if the server is not being hit too heavy. To answer your question directly, yes, it will start to slow down as you have more people using the system. I would suggest you consider the following. 1: Use ADODB as your abstraction layer. It has built in query caching and could dramatically improve page speed as well as lower processor usage. 2: Take a hard look at your code and make sure you actually need 20 queries on a page. Would a single query be possible and then spin through the result set? 3: Consider moving to a Linux box. (Sorry, had to be said) Without the overhead of a GUI, your processor will be more available for mysql and your web server. 4: Make sure you have the proper indexes set. If you do need 20 queries, 20 fast queries are better than 20 slow queries. :) HTH.

[PHP-DB] Sort Order Description

Re: [PHP-DB] Re: Sort Order Description
I'm not clear on your question. The code I quoted, set forth below, has
the text that ends up above the table. The following introduces the
series of column headings with sort statements (of which the initial code
is one):
# write out title
if ($sort_order == asc) {$sort_title = Ascending;} else {$sort_title =
Descending;}
echo pbData Set Sorted By $sort_field in $sort_title
Order/b/p\n;
# write out table heading
echo table width='75%' border='1' cellspacing='0' cellpadding='0'
align='center' bgcolor='#99'\n;
echo tr\n;
The following is at the beginning of the script:
# get sort order (if any) passed to script
$sort_field = $_REQUEST['sort_field'];
if (! $sort_field) {$sort_field = (ssa1202.total/vapall.vapall)*100;}
$sort_order = $_REQUEST['sort_order'];
if (! $sort_order) {$sort_order = desc;}
Thanks.

First things first. That code (it seems to me) is vulnerable to SQL
