FirePHP not returning ajax request queries, yet returns normal page load queries


HOME ยป Web Design

I am using firePHP(Zend profiler) on on FF 3.6.3(firephp addon installed) and it returns queries, when I do a normal page load. Ajax requests, however, are not returning the proper queries. I am using Prototype 1.6.0.2 for ajax requests. Is there something I am missing? Most of the write-ups seem to imply that this should work by default.

how to prevent MySql Cross Join Query returning zero results if one of the queries returns null
Web Design

I use this query to fetch the ID of the Next and Previous Events in a mysql events table:


SELECT e.id AS current, prev.id AS previous, next.id AS next
FROM events e
CROSS JOIN
(
SELECT id FROM events
WHERE date < '{$result['date']}'
ORDER BY date DESC
LIMIT 1
) prev
CROSS JOIN
(
SELECT id
FROM events
WHERE date > '{$result['date']}'
ORDER BY date
LIMIT 1
) next
WHERE e.date = '{$result['date']}'

This query works fine.


lets pretend the table looks like so:

Count number of queries per page request?
Web Design

I need to know how many sql queries are being executed per page request. As the site is already done and I am just running optimization analysis, I would prefer if any solution offered doesnt require that i change the entire website structure.


I use a single connection to send all queries to the MySQL database:


define('DATABASE_SERVER', '127.0.0.1');
define('DATABASE_NAME', 'foco');
define('DATABASE_USERNAME', 'root');
define('DATABASE_PASSWORD', ');
$DB_CONNECTION = new mysqli(
DATABASE_SERVER,
DATABASE_USERNAME,
DATABASE_PASSWORD,
DATABASE_NAME,
3306
);

WCF Data Service returns 400 Bad Request for POST queries
Web Design

I need to host a WCF Data service as part of a legacy ASP.NET MVC website running in IIS 7 Integrated mode.


Read access to the web service is working fine, but whenever I try to POST to the web service, I get a 400 Bad Request error.


For testing purposes, I have downloaded the sample odata service from http://www.odata.org/developers/odata-sdk#/media/7582/odatasampleservices.zip. Posting to that webservice works fine when running it in a separate IIS website. However, when I put it in my legacy website, I am geting that 400 Bad Request error wen sending a post request to the service again.


Therefore the problem seems to be relat

When optimizing database queries, what exactly is the relationship between number of queries and size of queries?
Web Design

To optimize application speed, everyone always advises to minimize the number of queries an application makes to the database, consolidating them into fewer queries that retrieve more wherever possible.


However, this also always comes with the caution that data transferred is still data transferred, and just because you are making fewer queries doesn't make the data transferred free.


I'm in a situation where I can over-include on the query in order to cut down the number of queries, and simply remove the unwanted data in the application code.


Is there any type of a rule of thumb on how much of a cost there is to each query, to kn
