[PHP-DB] 1 TNS error out of 25 connections
HI I have a strange behaviour of my remote Apache-PHP-Oracle-Client. Apache 1.3.14 mod SSL PHP 4.0.3pl1 (everything compiled from sources) Oracle 8.1.6 on remote Intel/Redhat 6.2 (100MBit, same subnet) The Oracle Server runs a Multi-Threaded-Server (successfully) and accepts dedicated Serverconnections on the same Port. tnsnames.ora and sqlnet.ora are placed in the proper directories. it works in 95% of all requests, but sometimes (with no specific traffic reason or network problem) it shows an typical _oci_openserver_error: COULD NOT RESOLVE SERVICE NAME. I looked up Oracles Online Help but it's just like check your tnsnames.ora, check your servicename ... But as it works in 95% of all cases, I do not think that the problem is my path to tnsnames.ora Is there anyone that is familiar with that problem or the configuration of MTS and Dedicated at the same port / time ? thank you mk -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

Oracle Divides Function in several Groups
DML means Data-Manipulating function;
(in your funciton is a update or insert)
to use a function in a query it needs to be "pure" only selects and
arithmetics
you can rewrite this function to a procedure and return your value as an out
parameter
$stmt = ociparse($dbh,"BEGIN p_foo_procedure('param_in',:1);END;" );
OCIBindByName ($stmt,":1",$outparam,40);
ociexecute ($stmt);
OCIfreestatement($stmt);
40 is the buffer in chars/bytes (addjust if needed)
the procedure needs to declare the second argument as in and can declare the
second one as "out" or "in out"

WOrkaraund: using it as a string helped "$error" == "0" is always true when $error looks like a zero. there is no sign of some extra spaces or invisible chars. strlen is always 1 and print always prints 0.

you can use the meta column rownum

note: you need to do subselects and (where rownum 1) will never return a
line !!!
you could use something like
select * from
select rownum "rownumber", mydata from mytable order by

) where rownumber 10 and rownumber 20;
should work ...

Hi,
I'm using php with oracle to select data in a db.
1)
My code is:
putenv("ORACLE_HOME=/xx");
putenv("ORACLE_SID=xx");
$conn = ociLogon("xx","xx","xx");
$st = ociparse($conn,"select * from myTable order by MYFIELD");
$res = ociexecute($st,OCI_DEFAULT);
while(ocifetch($st))
{
...
}
This is ok, BUT:
I want to show records in pages with 20 records each one. How can I
obtain this?
I see that php asks all thousands records to (remote) oracle server,
slowing time. Is there something like:
ociexecute($st,OCI_DEFAULT, fromRec, toRec);
2)
How can I know the total records in current selection?
Thanks

and to get rows, say, from 20 to 40? Is it ok to write: "select * from (select * from table where foocondition order by foo) where rownum = 20 AND rownum = 40" its not that easy, as oracle start counting with the first retrieved row, so rownum x will wait for ever, as oracle will never start counting because no rows are retrieved. make a trick and select the rownum in a subquery, than you can treat it as a fixed row: select * from ( select rownum "rn", * from (select * from table where foocondition order by foo) ) where rn = 20 AND rn = 40 this should do it (although there are a lot of subqueries) -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

the TNS names must match, (consider that a default_DOmain might be added

the IP and Port of the remote DB have to match, as well as the Service or

Betreff: [PHP-DB] Oracle connectivity
There was a post a few days ago here that indicated that PHP could only talk
to Oracle databases if they resided on the same machine as the script
because PHP could not deal with the TNS resolutions or something to that
nature.
I have an Oracle database that I need to connect to on another machine (I'll
call it LIVE).
The tnsnames.ora has the appropriate entry in it for TNS resolution to an IP
connected database.
I used Net8 to create the DSN mapping.
When I use,
OCILogon("TEST","web","pwd");
I get a TNS resolution error (which I was able to FINALLY overcome), and now
I get "Could not connect to remote host." type error.
I am running WinNT 4.0 w/IIS, PHP4.
Now the reason I think its PHPs problem is because I can connect to the
database using ASP and VBScript.
I BELIEVE (not certain), that the client version I am running is 8.0.1.6. I
am "assuming" (yikes) that the phpoci.dll is the one I needed, not the
phporacle.dll. I have tried both and receive similar errors. Even using
the ODBC component of PHP returns similar errors as above.
Any suggestions are welcome.

AW: [PHP-DB] Oracle Persistant Connections
Yes, same question. The only thing i know about, is that, if you are running php not ass an module, your connection will die right ever script executing therefore making OCIPLogon = OCILogon. If run as module the connection will last till your server thread is regenerated. Therefore it can have a very dark side effect if the connections are not reliable reused: imagine 250 Apache Spawns with each hundreds of OCI-COnnections still open ... be carefull! And this is exactly my problem. I can not try tghis since the machine is running heavy traffic unless i know at leasst the theory Another Idea of reduicing Logon overhead is to run the server in MTS - Mode which does not cause the Oracle Server to start an dedicated ServerProcess for every Logon/Session.

So you like to let the SQL check for those constraints and you want only the PHP to deal with that ugly error: - disable the error output by placing @ before your php-function - catch the error either by checking $php_errormsg (works only if error-tracking is enabled) or by the result code or mssql_get_last_message - find your keyword and print an adapted message I'm working with MS-SQL 7 and IIS 4 as well as PHP4.0.4 --- My question is that when a message is received while attempting to delete a row in [table x] while it is tied to [table y.column a] by a foreign key relationship [see below] Warning: MS SQL message: DELETE statement conflicted with COLUMN REFERENCE constraint 'FK_COMPONENT_INDEX_page'.

AW: [PHP-DB] PHP PopUp Window
This is not exactly a DB-Problem but:
What I'm trying to do is after a user submits a form,
PHP validates the
form and if an error open a JavaScript popup window.
I'm having trouble-getting PHP to either run the JavaScript
or send the
information to the browser so it can execute the JavaScript.
Remember that PHP can't execute Javascripts !! it can only produce
javascripts like
$error = "No Name entered";
echo "scriptalert ('Your error is : $error !! ');/script";
Also on another note is it possible to hide the search
portion of a URL that
is sent using:
? header("Location: /index.php?hideme=yes"); ?
I don't like the user seeing the sometimes-long URL that is
sent using this
manner.
If you'd needn't the Redirect you could simply POST your formdata instead of
GET. Since you stick on that Location:... try using a frameset around ;-)
