Hi,
I'm having intermittent problems with queries from my php script to a
postgresql database.
I have a form where I can enter a search query - for instance a last
name. This leads to a results page with a brief bit of information
about each of the matching results. From there, I can click a link
associated with any of the results which takes me to a page with all of
the details. Pretty standard stuff.
Problem I'm having is that for some of the results, when I click the
link to go to the full details page, no information is returned by the
script. I basically end up with my html template & no data populated.
For the majority of items, things work just fine.
One thing I've noticed is that it seems to be reproducable - that is,
for example item 5123 always fails to return any results on the full
details page.
>From my Postgres box (windows 2003), I can run the exact same query as
from my PHP script (with item id 5123) & it returns the data.
So what could the problem possibly be?
I thought that perhaps it was a load issue on the server - couldn't
answer the query, but the fact that it's reproducible seems to nix that
idea. Also, that Postgres box has 3.5 GB of RAM & we're talking about
a test system at this point - I'm the only one using it.
Code for my first search results page (basic info & hyperlinks) looks
like this ($name_last is the variable passed from the search form):
$connection=pg_connect("host=10.10.10.2 port=5432 dbname=db1
user=dbuser password=password");
$myresult = pg_exec($connection, "SELECT identification_no, name_last
, name_first, name_middle FROM public.j_identification WHERE name_last
~*
'$name_last'");
The code for my detailed results page looks like this:
$connection = pg_connect("host=10.10.10.2 port=5432 dbname=db1
user=dbuser password=password");
$myresult = pg_exec($connection, "SELECT * FROM
public.archived_with_photos
WHERE identification_no = '$id_no'");
'public.archived_with_photos' is a view defined on the postgresql
server.
I can run the query
SELECT * FROM public.archived_with_photos WHERE identification_no =
'5123';
and it returns all of the associated data from the database... whereby
the exact same query failed with the PHP script.
Any help or ideas greatly appreciated!
