Re: [PHP-DB] Splitting a CSV file
Chris, If you are on a Redhat machine, you could try running a CLI command on this. Try looking up the 'split' command, it may solve your problem if you combine it with some PHP. -Matt On Mon, 2003-11-24 at 19:14, Chris Payne wrote: Hi there everyone, I'm writing an automation system to automatically insert data into a mysql database from a CSV file, and it works great - until I try to insert a large file, then it just doesn't do anything. I've set my PHP filesize to 10 Megs so that's not the issue, and a server timeout isn't the issue either. So, is that a way that I can split a CSV file into 2 files if it's larger than a certain size so that I can still use the automation I am working on? Actually, I won't see the files as it's for a company who just wants to be able to select their CSV file (No matter what size) and it will insert it automatically, and as I said it does work on small files but not large :-( Any help would really be appreciated.

[PHP-DB] Need some MySQL Optimization suggestions - uber slow queries
I have a page that when all said and done is super slow. The queries are running a bunch of JOINs and SORTs and WHEREs. I recently implemented the my-large.cnf file in hopes it would help out the situation, but the change appears negligible. Does anyone have any suggestions for speeding up the query process...a lot?

Re: [PHP-DB] Need to Run a PHP script using CRON or ?
Goto your shell and type php -i w/o the quotes. You should see the phpinfo() output. You can pass the path to your script as a command line variable, and it will process it. Here, read about it, I think this is the right answer for you: http://us3.php.net/features.commandline Matt On Mon, 2003-09-15 at 15:41, Jonathan Villa wrote: I have an application which creates temporary tables.

[PHP-DB] changing datatypes in the query
Hi all- Tough question (I think). I am pulling some numbers out of a data base, currently they are stored in a blob. When I try to order by user_hits desc it does a text ordering, not a numerical ordering. Is there a way to get it to do a numeric ordering?

Re: [PHP-DB] changing datatypes in the query

[PHP-DB] storing serialized() data in the db - can it be queried on?
Hi All- I don't think that this is possible but maybe through some custom function perhaps? I am storing data in a database, and it is an Array (in PHP) so I serialized it for storage. I want to be able to query that data and be able to do something like WHERE thisField = 'john'. the field 'thisField' though would need to be pointing to the first element in the Array, which I don't think is possible.

Yes. You only need to maintain one list, actually, the list of things
that the user has viewed. Then, do something like this:
$list = ' . implode(',',$_SESSION['viewed_hash']) . ';
$query = SELECT thing FROM Thing_Table WHERE thing_hash NOT IN ($list);
Run that query and you'll have all of the results in the table that the
view has not seen.

RE: [PHP-DB] help with $_Get in form
Just from quickly looking you are trying to submit a form and grab the
submitted value and stick it into the DB?
If so try using METHOD=POST on your form, and using the variable
$_POST[form_field] in the insert statement

[PHP-DB] MySQL Clustering, redundancy
Hi All: I quickly skimmed the MySQL manual and didn't see any information on clustering. Does MySQL have any support for clustering or some type of redundant failover systems? Thanks!

RE: [PHP-DB] MySQL Clustering, redundancy
Thanks for your response Adam! Do you know if there is any way MySQL can be spread across multiple machines? I am looking at a huge application for a client, that will need to support thousands of simultaneous users. I am wondering if MySQL can handle load like that. That's why I was asking about clustering MySQL servers for the ability to handle more users simultaneously. Has anyone had any experience with a large scale application on MySQL?

However, since the info in the manual is kind of sparse so I would hop on google and do a search for specific instructions on how to do it when your ready, but to answer your question, yes, MySQL does do Redundancy/Failover. (Ofcourse you must take account of this in your code interacting with the server, but the data will be sync'd).
