Re: [PHP] PHP-MYSQL Question
This isn't PHP but mysql question.
You didn't mention that the table itslef is created or not. If not, then it
is probably a mysql error,
maybe your installation of mysql doesn't support INNODB.

Re: [PHP] PHP/mySQL question using ORDER BY with logic

Basically I've got data coming from the database where a wine producer-name is a word like: Château Bahans Haut-Brion or La Chapelle de La Mission Haut-Brion or Le Clarence de Haut-Brion but I need to ORDER BY using a varient of the string: 1) If it begins with Château, don't include Chateau in the string to order by. 2) If it begins with La, don't order by La, unless the first word is Chateau, and then go ahead and order by La. Example sort: Notice how the producer as-in comes before the parenthesis, but the ORDER BY actually occurs after a re-ordering of the producer-string, using the above rules.

I think it might involve a mySQL alias-technique but I could be wrong. Right now, my PHP call to generate the search is this: $query = 'SELECT * FROM wine WHERE MATCH(producer, varietal, appellation, designation, region, vineyard, subregion, country, vintage) AGAINST ( ' . $searchstring . ') ORDER BY producer LIMIT 0,100'; Maybe there's a good way to do it with the table as is... but I'm doubtful. I would create a second field that contains a pre-processed version of the name that performs stripping to achieve what you want. This could be done by a PHP script when the data is inserted into the database, or if not possible like that, then a cron job could run once in a while, check for entries with this field empty and generate it.

RE: [PHP] PHP/mySQL question about groups
You are correct, but that is what I meant by all columns (all those in the query, and therefore subject to the distinct). At this point different database engines work differently, without an order by, some will use the primary sequence, some will scan table space (in other words, without an order by [or group by], some engines will give you a performance hit). It's always good practice to write your queries to help your DB engine find an index.

That's something MySQL will allow that IMO it should not. Being able to use SELECT * and GROUP BY at the same time can create confusion as it did here.

$query .= AND Deceased = 'N' ;
}
$query .= AND (First_name like '%$name%' or Last_name like '%$name%'

$query = select * from honorclub;
if ($dead != || $unknown != || $name != || $county != ||
$year != || $countynow != || $state != )
{$query .= WHERE ;}

{$query .= `Deceased`='N' AND;}
if ($unknown == )

What needs to be 'OR' is the $name section to be:

OR

// loops through the entire recordset
while( $qrResults = mysql_fetch_array( $rQuery )) {
print( $qrResults["SomeField"]

// reset the recordpointer to the first record
mysql_data_seek( $rQuery, 0 );
