[PHP-DB] database sends unclear messages
Hi there, I have a LAMP appplication which sends a report via email if a database error occures. This workes pretty fine. The message contains sql statement and error message from the db server. Lately there are lots of errors showing up every few days which look not like sql errors. Sometimes the message only contains error executing mysql statement: And thats it. In most cases it contains the sql statement as well (as it should!), but the error message from the sql server is missing. So this seems to be a problem of the server. I am running a 1 year old mysql version which might contain bugs. My guess is that there is a machine crawling my site which brings the server down. But I cant prove it. If such a message occures it always comes with tens or even hundred messages all sent in a few or even one minute. Has anybody a suggestion what to do, or a hint what could be happening here? Thanx a lot in advance, Merlin -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP-DB] User defined function in a mysql query
1. Is the function allowed by MySQL? 2. Can you execute the function before the query, assign what it returns to a var, then place the var in your query?

Re: [PHP-DB] User defined function in a mysql query
From: antonio bernabei [EMAIL PROTECTED] I need to make a join between two tables. And I can use the mysql_query function: this is ok.

Although it'll negate any indexes you have and make for a very slow join.

[PHP-DB] Cookies with fopen
Hi all, Attempting to use PHP to navigate a foreign website, to collect data. This is thus only tangentially related to databases, so I apologize if some feel it's too off-topic. Is there any way to do something similar to fopen() except to also have PHP present a cookie to the foreign webserver as credentials during the HTTP GET?

You can use it to send authentication information or to login to a page and it will keep track of cookies for you. http://pear.php.net/package/HTTP_Client If all you need is to do one request, it may be easier to use HTTP_Request instead. -- paperCrane Justin Patrin -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP-DB] ordering output
I have a page that I put together that pulls in data for the time in individual fields - hour, minute, am/pm, month, day. I am going to alter the db to add year as well. I want to order this list by multiple criteria - first by year, then by hour, am/pm, minute. It is a page that lists shows that are running on a local cable channel. Is there a way to do what I am asking? I know that I can 'select * from table order by year asc' but don't know how to sub order the items. thanks, DF -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP-DB] Missing Data in Columns
Only six of ten columns in a php table show up on the web. I've been using a standard format for many months now and the only difference here is that I'm drawing on more (seven) tables. Even more curious, running the select and where statements in mysql produces the full table. Also, clicking on Sort in a blank Vote column rearranges the visible vote columns which suggests sorting based on the invisible column. Worse (which I won't try to solve here), when I delete some select statements the table disappears. The link and select statement are shown below (I won't copy the extensive where statement, but the table didn't appear when that was wrong). Any ideas?

When you start looking for things that span certain lengths of time, you'll thank yourself. You can still pull each part out if need be. You'll also only need to sort based upon the single column. ---John Holmes... -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
