[PHP-DB] setting a timeout on ocilogon
Hi, I have a script that connects to a database which is in another country and connected to our network thru a VPN. The script tries to connect using ocilogon() and checks if a connection is established. If not, it presents the visitor with a nice errorpage. However, ocilogon takes a very long time before it returns control to the script (ie aborts the connection) if it fails. I would like ocilogon to quit trying after eg 10 seconds. How can I do that?

Re: [PHP-DB] MySQL query problems...
yeah...errora are important. I do not escape my quotation marks in a
query. I use single quotes within my insert and select statements.
If it says No valis MySQL resource then you are returning 0 records
which may be caused by escaping the quotations.
I follow this pattern
$sql =INSERT INTO table VALUES ('some value','another value','etc');

Re: [PHP-DB] MySQL query problems...
Not quite correct, No valis MySQL resource means the query and/or link
failed in connection in some way. A correct and proper query MAY easily
return 0 rows and that is correct and will give you a valid resource
(handle) and simply no data.

My problem is that ocilogon takes a long time to return control if the connection cannot be established - often even more than 30 seconds. I've learned that if a connection can be established it'll happen in only a few seconds (usually within 1 second) and am convinced that if the connection is not established in eg 5 seconds, there is no point in waiting another eg 30 seconds.

[snip] I can't claim whether or not it will work since I don't have an Oracle server handy, so I will merely name functions and talk a bunch. Essentially, you want ocilogon (complex network function to login to a networked Oracle [in this case] server) to timeout just like fsockopen (fairly simple function to open a socket, including network resources). My suggestion is to try connecting using fsockopen, with the timeout. If it successfully connects - chances are, the majority of the time, your ocilogon that follows will work as well. Unfortunately, the stream_set_* functions rely on a valid stream resource, so they won't work with ocilogon (if there was any chance they would). That would have been a nice route to go otherwise. Another dirty little trick you might use is running the ocilogon in a separate script and making use of set_time_limit() to make sure it doesn't run too long.

RE: [PHP-DB] MySQL query problems...
OK. I think I have resolved this issue. The problem I am
having now is that I have a simple table that is a list of systems to
exclude from the display. I am having trouble figuring out how to
structure my query to actually exclude the systems in this table. Here
is what I tried, and it gives me 13 instances of every entry, 13 is the
number of hostnames in the exclusion table.
$query = SELECT AllMid_Data.CPU_Hostname FROM AllMid_Data, exclusion
WHERE AllMid_Data.CPU_IN_SVC = \Y\
AND AllMid_Data.CPU_DNS = \sbcld.sbc.com\
AND AllMid_Data.CPU_Hostname != exclusion.hostname
ORDER BY CPU_Hostname ASC;
$results = mysql_query($query, $Prod) or die(mysql_error());
$system = mysql_fetch_assoc($results);
Additionally, what I am actually working towards is that if a
system shows up in either of the other queries it gets excluded from
this one. I have not tried anything to make that happen yet. I will
tackle that challenge once I can resolve this part. Thanks again.

Does a table named round1 exist in your database? If so and you are using mysql 4.0.4 you will need to mention all tables referenced in the WHERE clause in the UPDATE clause. e.g. UPDATE tipping, round1 SET tipping.score = 3 WHERE round1.game1 = 'H' AND tipping.username = 'jerry' (assuming the score column you want to update is in the tipping table...) You almost certainly want to join the two tables as well but without knowing your database it is impossible for me to say how.

In your case it looks like AND acct_db.key1 LIKE \%\.AllMid_Data.CPU_Hostname is adding AND acct_db.key1 LIKE %.AllMid_Data.CPU_Hostname and you can't join two strings in SQL with a '.' like you can in PHP you should use a + for the two strings.

[PHP-DB] OCI ignoring NLS_DATE_FORMAT parameter
Regardless of how I set the NLS_DATE_FORMAT parameter, when I do a select statement DATE fields are returned in the Oracle default DD-MON-RR format. I can successfully set NLS_DATE_FORMAT using either an environment variable and restarting apache or by using ALTER SESSION SET NLS_DATE_FORMAT = 'DD-MM- HH24:MI:SS' (I would prefer to use this method). I can verify that the NLS_DATE_FORMAT is set to my desired format both before and after my select statement by running the query SELECT * FROM NLS_SESSION_PARAMETERS WHERE PARAMETER='NLS_DATE_FORMAT' in my script. This problem occurs with both PEAR DB, and with ADODB oci8 drivers. However if I use the ADODB oracle drivers, which use the older ora functions instead of the oci functions, ALTER SESSION works and I am able to retrieve dates in the format I set. Unfortunately, the software I'm working on uses PEAR DB_DataObject, and the PEAR DB Oracle driver uses the oci calls. Version info: Oracle9i Enterprise Edition Release 9.2.0.4.0 - 64bit Production PHP 4.3.4 Apache 1.3.29 Anyone have any ideas or suggestions on why I'm seeing this problem?
