[PHP-DB] IBM DB2 and php
Maybe in early August, I got my code to work with DB2 8.1.3 via ODBC
after a bit of teeth pulling.
I played with it for about 2-3 weeks, and it seemed ok (slow but ok).
Earlier this past week, I was modifying the DB drivers for my script,
and now, DB2 refuses to cooperate.
I don't remember changing any php.ini settings so Im confused as to why
it doesn't work now.
Im testing on w2k, php 4.3.3, db2 8.1.3
The problem revolves around field lengths being too long, because, as
soon as I select
a text field, the query fails, when trying to retrieve specific result rows.
If anyone can shed any light on this, I would greatly appreciate it.
Thanks

$result = odbc_exec($db-_connection_id, $sql);
odbc_longreadlen($result, 0);
odbc_binmode($result, 0);
// Trying to retrieve 2nd row out of 6 rows returns false when
// the query contains a text field

[PHP-DB] Ranges query gone wild
Hi. I have a MySQL table where a product price ranges are set according to quantities. For instance for a certain product you'd have (besides id columns): range_begin | range_end | range_price 0 | 35 | 1.5 36 | 70 | 2 71 | - | 3 Where '-' is always the character that means '..and above' and closes the entire range field. So in the above example a quantity of 71 and above has a price tag - $3. I have limited success with writing the simple query that when given a quantity returns its correct price range. This is what I came up with: SELECT `range_price` FROM `price_ranges` WHERE `product_id` = '$product_id' `size_id` = '$size_id' ((`range_begin` = '$quantity' `range_end` = '-') || (`range_begin` = '$quantity' `range_end` = '$quantity')); It partially works. But given the above example, it'll correctly return for a quantity of 71-79 the price of 3, but for anything above that it'll return the wrong price - 1.5. It works fine if I remove the second part of the OR construct. Also it returns nothing for the quantities of 4-9 (?!). I've tested this on my machine (MySQL ver: 3.23.54) and on the customer's server (ver: 4.0.14), and got the same results. Obviously I'm not getting the logical scheme right. If anyone can point out the problem or suggest a better way to write the query I'd appreciate it.

[PHP-DB] PHP/MySQL Help
From: Conbud [EMAIL PROTECTED] To: [EMAIL PROTECTED] Subject: PHP/MySQL/Server not working Date: Friday, October 17, 2003 6:17 PM Hey, just a quick question, I have a form that users can fill out to join a certain group, we can then view that info from an admin page that requires logging in. When a user fills out the form I get an email letting me know that the form was submitted with the users info as well. Here recently, I've been getting that info but their info isn't being saved into the database for somereason, anyone have any idea why ? I have filled out the form at least 15-25 times using different info and everyone of them worked for me. I even filled out the form using different special characters and still with no problems, I am using stripslashes on the form data, but I don't think that could keep the info from being saved to the database, it only does this periodically. Could this be due to a slow server ? or is there some sort of special character that could conflict with my PHP or with the MySQL syntax ? I just have no clue now. Any thoughts are appreciated.

[PHP-DB] Re: PHP/MySQL Help
Hey, Also the webhost only allows us a direct database connection using phpMyadmin, I did notice that on the table that stores the info, it keep getting an error after someone is posting the form. The error says something about Overhead: 275 bytes, Is this just an MySQL limitation that is set by the webhost ? and this overhead you think that would keep the info from being entered into the database. To get the error to go away I have to optimize the table.

Re: [PHP-DB] $_POST in MySQL query issue...
A couple of days ago I placed a post regarding using the $_POST[]
variable in an insert sql query. Both
$sql=insert into $table set Name = '.$_POST['elementName'].';
and
$sql=insert into $table set Name = '{$_POST['elementName']}';
worked perfectly. Thanks to everyone for your help. My question now is
regarding the curly brackets in the 2nd example. Can anyone describe
why using the curly brackets works and/or how php processes them. I
have read quite a bit about php and never come accross thier use in this
way. Thanks again.

The only remark which I would make here is to beware of SQL injection.
Here are a couple of good resources to explain what an SQL injection
attack is and what you should do to protect your code:

[PHP-DB] WHERE statement used multiple times.
Hi, If I was to want to use the WHERE statement multiple times (more than once) how do I seperate each WHERE statement? Would it be with a ',' (coma) or a ' ' (space) or what? Or not possible to have multiple WHERE's in the one query? I need 2 tables checked before executing the results. So that is why I need 2 WHERE statements done.

You can put together WHERE statements with an AND or an OR. For instance, SELECT id FROM users WHERE id='2' OR id='3' You know, if you had a few suspicions about this sort of thing you could always give it a spin in a Query. Worst case scenario is you will get an error. - Chris -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
