[PHP-DB] PostgreSQL lib and character case
I use pg_fetch_array() to get a record content. But it seems that to access elements of the returned associative array, I should use lowercase field names. Is there any way to use case-insensitive field names? -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP-DB] MySQL - counting number of instances of a word in a field
It is easy to get around this limitation: for each column containing indexable content, create a shadow column containing content prepared for FULLTEXT indexing. I usually do the following: - for each word: - replace all non whitespace, non-blank characters by _ - right pad to 4 with _ for example B.M.W. become B_M_W_, tax will become tax_ now you prepare similarly the string to MATCH actually doing so is good personal hygiene regardless of the value of ft_max_len set by the host. it is mandatory when you deal with languages which do not separate words by whitespaces (in my case Japanese) HTH Ignatius _ - Original Message - From: Gavin Amm [EMAIL PROTECTED] To: Ignatius Reilly [EMAIL PROTECTED] Sent: Wednesday, April 28, 2004 10:03 AM Subject: RE: [PHP-DB] MySQL - counting number of instances of a word in a field Yes, They do.

Hi - Tumurbaatar S. wrote: I use pg_fetch_array() to get a record content. But it seems that to access elements of the returned associative array, I should use lowercase field names. Is there any way to use case-insensitive field names? This is how Postgres works: it always returns arrays indexed with lowercase results. AFAIK there's no way to change this behavior from PHP. In general, it's important to know that different databases do this differently: - MySQL will return case matching the case of column names in the db -- or if you specify column names in your select clause (SELECT myColUmnName FROM ...) then the case of the array will match the case you use in your SELECT clause. - Oracle will return all UPPERCASE column names. - SQLite is configurable (defaults to mixed case) - PostgreSQL returns all lowercase ... etc. Of course, as someone mentioned, you can always col strtolower() when trying to access a column from postgres result set: $arr = pg_fetch_array($q); $value = $arr[ strtolower($mixedCaseColName) ]; It's best practice to use a database abstraction layer that provides column name case changing portability features -- like PEAR::DB or Creole. That way you can always use a single case (e.g. lowercase) for accessing columns and you won't have to rewrite all your code when you try to deploy your app on Oracle.

RE: [PHP-DB] Request for help on (My)SQL Statement
That would work except I'd change the last line to send email. The problem is the
users are showing up to see any alert of new posts on the site. And when they do
access PHPBB it will highlight those topics that have new posts anyway. Just got to
get them there in the first place.
Thanks,
John

Well then there's no reason to copy the value. Just select from the BB table.
Just:
$l = mysql_fetch_array(mysql_query(SELECT max(post_time) as latest_post FROM
nuke_phpbb_posts));
$s = mysql_fetch_array(mysql_query(SELECT max(script_run_date) as
latest_script from script_data)
if ($l['latest_post'] $s['latest_script']) {
echo NEW POSTS!;
}
Or something of that nature. I've done this in the past by setting a cookie on
the user's system when they log in so I know the last time they logged in,
and then you can count how many posts have been made since they were there
last.. that works pretty good.

The client is trying to generate traffic - the members aren't using the
site. She figures if they are reminded when there's activity on the site
(without just forwarding all posts to the members - she doesn't want to
turn it into a mailing list per se) they'll start using it.
The design may be flawed but I don't know any other way to do it. As long
as it serves the purpose and isn't a total abomination... :)

Not with MySQL that I know of, some local guru might have an idea..
Why are you storing the data in another table? Usually duplicating data in
a database is a big signal of flawed design. If you're using it somewhere
else, just select it from the originating table each time. Unless you're
trying to do something else that I'm not taking into account.

That would be the way to do it except that MySQL doesn't support
sub-selects until version 4.1, which is in alpha still.

:::Novice Alert:::
I've done simple select and insert statements, so I suppose this is the
most complicated thing I've tried to do. but seems to me it should be
pretty easy. But I'm a designer by background, not a developer or
programmer. I've got everything else I'm trying to do working.
I'm trying to take the largest value out of one table and update
another table. The former is a PHPBB table and the latter is a table I
created just to store the value of the date of the most recent post for
use in something else.
UPDATE ngc_polling SET lastrundate = max(nuke_phpbb_posts.post_time)
It returns Invalid use of group function.
I've been looking at the documentation on MySQL.com to no avail. I'm
testing my query in phpMyAdmin before I try to implement it elsewhere.
This is what I'm trying to do, any help besides RTFM (been doing
that) would be greatly appreciated.
Thanks!

No. PHP is case-sensitive, so you have to use lower case (unless you made the relation name case-sensitive when you created the PG table). -- 19:21:02 up 43 min, 6 users, load average: 1.46, 0.73, 0.58 - Martín Marqués| select 'mmarques' || '@' || 'unl.edu.ar' Centro de Telematica | DBA, Programador, Administrador Universidad Nacional del Litoral - -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Hi Matt
You can teat a string like an Array
$first = $string[0];
$second = $string[1]
and so on.
Actually this method is deprecated. The current best way is to use curly
braces.
$first = $string{0};
$second = $string{1};
