Re: [PHP-DB] Creating an INDEX on multiple tables?
I have moved the GROUP BY outside now Chris.
In the queries that make up the UNION ALL (such as below) is there a way to
only SELECT matches that are 70% or greater based on the users input? Right
now each and every listing is a search result.

[PHP-DB] [PHP5 AdoDB] Correct return value after oracle package function call should be a string and I get a number instead.
Hello.
I'm using PHP5 and ADODb(could not find a version number for the life of me,
the closest thing I could
find is an old-changelog.htm file topping version 3.92.22 well buried in a
docs folder).
I have this php code:
/*getTitoloFromID si riferisce alla tabella CONF_RELAZIONI!!!*/
function getTitoloFromID( $anno, $trimestre,$id )
{
$r_titolo = str_pad('', 50,'@');
$params = array(
'p_anno'= $anno,
'p_trimestre' = $trimestre,
'p_id'= $id,
'r_titolo'= $r_titolo
);
trace( 'Parametri: ');
trace( $params );
$sql = BEGIN :r_titolo :=
PKG_RELAZIONI.getTitoloFromID(:p_anno,:p_trimestre,:p_id); END;;
$this-Execute($sql, $params);
trace( 'Titolo nella chiamata: '.$r_titolo);
return $r_titolo;
}
Backend is Oracle(don't know the version, again don't have a clue where to
look for it, but I'm
pretty sure it's above 9 because we use constructs that... d'oh! are present
from ver 9 on :D).
When I check the LOGS table in my db, I see the *correct* result being
added.
When this value gets to PHP, however, something happens and I receive the
value 1(without quotes)
without any apparent reason. The correct value is a string and, again, it
gets displayed in the logs
table correctly, hence I assume the SQL is correct.
I am also sure it does not depend on the params(trimestre means quarter, the
first thing I thought was
that I could be misplacing parameters or something like that) but that's not
the case either.
Return value is properly sized because I had already received the invalid
buffer size error.
Other calls use the same pattern and they all work beautifully.
I am pretty much at loss and would love some help nailing this because I
can't seem to
wrap my head around it :-)
Many thanks for reading this :-)
Andrew

[PHP-DB] big table / hadoop / map reduce
Hi there guys and girls Have anyone came across any reasonable explanation / articles on how hadoop and map reduce work in practice? i have read a few articles now and then and i must say i am puzzled am i stupid or they just cant find an easy way to explain it? :P What i would hope for is explanation on simple example of application with some code samples preferably. anyone good at it here? cheers -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP-DB] big table / hadoop / map reduce
Hi Artur, Here is an article on wikipedia: http://en.wikipedia.org/wiki/MapReduce And here are the native implementations in php: http://www.php.net/manual/en/function.array-map.php http://www.php.net/manual/en/function.array-reduce.php The basic idea is to gather a lot of data, from several nodes, and map them togheter; then, assuming a lot of this data is repeated across the dataset, we reduce them.

Re: [PHP-DB] big table / hadoop / map reduce
hehe sorry but this does not help :-) i can google for wikipedia definitions. I was hoping for some really good articles/examples that would put it into enough context. I would like to have good idea when it could be useful. So far had no luck with that. Its like with design patterns ... people who dont understand them should not write articles trying to explain them to others :P Art On 22 October 2010 15:29, Andrés G.

Re: [PHP-DB] big table / hadoop / map reduce
Imagine you have to get track of some kind of traffic, for example, ad impressions; lets supose that you have millions of those hits; you will have to have a few servers to receive the notifications of the impression of an ad. After the end of the day, you will have that info across a bunch of servers; mostly you will have a record of each impression indicating the Identifier (id) of the Ad. To this info to become useful, you will have to agregate it; for example to know which is the Ad with most impressions. You will have to iterate over all servers and MAP the info into one place; now that you have all the info, you will have to REDUCE it; so you will have one record per Ad identifier indicating the TOTAL impressions of that day. That's the basic idea. It's like aftermath of Divide and Conquer. Hope this will be useful. Cheers.

[PHP-DB] How to Sync MySQL with iPhone or Google Contacts
Hey all! Does anyone know how to go about syncing a MySQL db with an iPhone over the internet? An alternative would be syncing with Google Contacts, which then could sync with the iPhone. I think Google Contacts uses Exchange Server to sync with devices. Thanks! - Ron -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP-DB] How to Sync MySQL with iPhone or Google Contacts
I believe there is a MySQL for the iphone iMy? http://forums.mysql.com/read.php?58,249718,249718 You'd probably want o use JASON or an equiv. to talk back and forth with your database and app. At least thats the consensus I'm finding on posts about it.
