Re: [PHP-DB] PHP and OCI NLS behaviour
Rouvas Stathis wrote: Hi, place appropriate NLS_LANG definitions in the Apache startup script (/etc/rc.d/apache ?). As a background to this, it's essential to do this because certain things happen when the module is initialised in PHP. Hence if you use putenv() to alter some Oracle defaults, it may well be too late because that option has already been set then the module was loaded (i.e. when Apache starts).

RE: [PHP-DB] Help -- Oracle
Help, i'm trying to connect to a remote oracle database from win98/apache/php4 and win2k/iis/php4 but it always gives me tns error. Other apps however, works fine with the tns configuration. the php oracle module was loaded successfully on both platforms. I've tried all sorts of possibilities. path to tnsnames.ora is correct. I've even tried with ODBC but when i used it with php, i get server refused connection. However, ODBC test was successfull and other apps can work with it. Can you give us the exact error message?

Re: [PHP-DB] Oracle Oci*Logon
Quoting Andrey Hristov [EMAIL PROTECTED]: Can someone tell more about OciPLogon. I'm sure Theis will add to this but here goes... :) I know that OciLogon is used frequently but the connection to the DB is shared amongst the pages so as in the common way where every page in a site uses one pair user/password use the only channel. When one script makes commit it commits all, so if two scripts subsequently made insert but one thinks that there was a fail it will issue rollback. The problem is that the other script issued commit and rollback does nothing. Someone can tell that the decision is using OciNLogon - ok but I know that this is the most time consuming way to connect to Oracle. The refined question is: Does OciPlogon is like OciLogon - one channel, one scripts commits/rollbacks all statements, or it is like OciNLogon but the connection is not made everytime a scripts want such but used already created one?. Oracle connections work across 3 levels, the server, the session and the service. AFAIK, transactions work at the service level which is the 'top' level. Persistent connections operate at the session level. Tus a persistent connection is maintained across Apache children by keeping the bottom level or server context open. We did run into problems because we have very high traffic sites and we have 100 Apache children running. Because our junior programmer decided to hammer the server with a web stress tool, al the children ran up connections which combined with connections on other web server made us run out of sessions. Dropping back to icologon() for a while helped the problem. Anyway, to answer your question, persistent logins will not affect transactions across processes as far as I'm aware. There may be some locking/isolations issues if a simultaneous read/write occurs but Oracle should handle that anyway. ocinlogon() is used to guarantee an isolated connection which will not affect any outstanding transactions. You only usually do this when you want to do a seperate set of operations in the middle of a transaction in a script. One more question : When PHP and Oracle works on one machine to make all work the enviroment variable ORACLE_HOME has to be set for example : /***/ // set ORACLE Dir to get the NET8 name resolver working // tnsnames.ora has to be in $ORACLE_HOME/networking/admin/ putenv(ORACLE_HOME=/home/oracle01/app/oracle/product/8.1.5); This is bad. As Theis has pointed out proviously, PHP modules perform certain operations at Apache startup and shutdown as well as script startup and shutdown. Setting things like ORACLE_HOME, NLS_LANG and so on in your script can cause some problems as some of the module has already been initialised before your script executes. You're better off putting this stuff in somewhere like the apachectl script. /***/ but if my web server is an Apache under windows and the oracle is on other machine under Linux(RH), what have to be done to make my PHP work with the DB. Windows is a slightly different beast. Normally the environment stuff is handled in windows and you don't need to setup anything with putenv. Use your Net8 Configuration assistant which is part of the Oracle Windows client libraries to create the correct TNSNAMES.ORA. AFAIK (I've never tried not to) you must specify the SID when connecting under windows in a PHP script.

Re: [PHP-DB] oracle (oci8) intro
Quoting Cynic [EMAIL PROTECTED]: Hi there, I'm in a situation where I need to produce a small app on top of an Oracle server really quickly. I'm quite a seasoned developer, but have only experience with MySQL so far. It's my understanding that Oracle lacks the MySQL's LIMIT feature. Looking at the OCI section of the PHP manual, it also looks like there's no OCIDataSeek() or some equivalent. Since the app I need to build will be a standard report builder with paging, I need this functionality. What is the common way to achieve this? Always fetch all rows, cycling through the resultset, discarding the records that preceed the one I want to start displaying with, and quit when I reach the one where the page should end? Is there a PHP + OCI tutorial somewhere? I need an intro to Oracle, and I need it now. :( Thies has an Oracle/PHP tutorial online at http://conf.php.net/ which may be of some assitance. The LIMIT problem is a real bitch is Oracle. There are a few ways to get around it, the most obvious people use being ROWNUM. However, ROWNUM does not listen to sorting which makes life amusing. One option is to try a query like the following: SELECT * FROM (SELECT field1, field2 FROM table WHERE id10 ORDER BY field1 DESC) WHERE ROWNUM11 which gives you 10 rows, but still leaves the question of paging behind unless you use between values. I can't say I've tried paging record sets though.

Re: [PHP-DB] OCIDefineByName/OCIBindByName help?
Quoting Barry Prentiss [EMAIL PROTECTED]: Hi, Can anyone help me to understand the OCIBindByName/OCIDefineByName functionality when used with the Oracle 'returning' clause? These two functions are seriously under-documented at PHP.net. I need the sequence-generated ID created during an insert for further manipulation. I tried sequence-name.currval but got an error. Here's some code that doesn't work: $sql = insert into mdfaq values (null,'$Question','$Answer') returning ID into :ID; $stmt = ociParse($conn,$sql); OCIBindByName($stmt,:ID,$faq_ID,-1); You don't need to pass by reference and you should be able to ommit the length parameter. You should probably bind $Question and $Answer as well. That way your queries will be more efficient and you dont have to worry about escaping quotes. Also your SQL should be INSERT INTO mdfaq VALUES (sequence.nextval, '$Question', '$Answer') returning ID into :id ID should be the column name of your primary key column. ocidefinebyname is useful for pulling columns out of Oracle so you don't need to make calls to ociresult() all the time.

RE: [PHP-DB] MSSQL: Spaces in database name
Quoting Robert D. Young [EMAIL PROTECTED]: That did it! Using: ... stuff $dbname = [Test Database]; ... more stuff mssql_select_db($dbname); worked perfectly. Again, Thanks! This is standard Microsoft (and maybe ODBC?) syntax. Using square brackets will work on most things including table names and field names with spaces in them. This will work fine SELECT [table space].[field space] FROM [table space] It doesn't mean that you should go around putting spaces in your database objects.

[PHP-DB] RE: Informix user wierdness
This is more an Informix question rather than a PHP question but
I hope someone can help
I've installed the Linux-SE version and CSDK of Informix from
informix.com and installation has gone fine including createing
the demo DB. I can also start 'dbaccess' and browse/query the
tables so the envvars seem fine.
However, when I endeavour to use the PHP functions, I get an
error in ifx_connect()
I constantly get the error:
E [SQLSTATE=IX 000 SQLCODE=-952]
User ()'s password is not correct for the database server.
Note how the username field is empty. What's the procedure for
'logging in' to the DB? I created the demo DB as a normal user
and I've read that the user auth stuff is done through the
operating system.
Using 'dbaccess' to try and connect to the DB as the same user
rather then starting dbaccess in the DB dir causes the same error
to occur so it's obviously something in the setup.
My sqlhosts line is 'demo_se seipcpipdev sqlexec'
and the ifx_connect line is 'ifx_connect("stores7@demo_se",
"testuser", "mypasswd")'
Answered my own question after taking some time out ;). Here's what I found
for the sake of the archives.
Turns out Informix has some sort of PAM/shadow password problem which means
it won't talk nicely because it tries to auth the user, but because of the
bug it can't get the user and therein lies the problem.
Luckily I'm on a dev box so I was able to run 'pwunconv' to return my passwd
file to a non shadow state which in a production system is 'not a good
thing'(tm)
A search in comp.databases.informix on google/deja on shadow and PAM etc
will reveal the problem. Apparently there are workarounds for this but I
haven't found the, yet. I suspect they will require surgery to something
important :)
Cheers,
Graeme

[PHP-DB] pg_put_line and file()
Hi.
I was tinkering around with pg_put_line and pg_end_copy and rather than
inserting data from a variable as per the example, I was wondering if it was
posible to insert the data from a delimited file via these two functions.
I produced a dump from postgres and tried inserting the data raw
$text = file("test.sql");
$db = pg_connect("host=localhost dbname=testing user=testing");
pg_exec($db, "COPY test FROM stdin");
foreach($text as $line) {
echo $line, "BR";
pg_put_line($db,$line);
flush();
}
pg_end_copy($db);
but this caused an error to occur. The example in the docs had the new lines
and tabs escaped so I tried that as well with addslashes()
$text = file("test.sql");
$db = pg_connect("host=localhost dbname=graeme user=graeme");
pg_exec($db, "COPY test FROM stdin");
foreach($text as $line) {
$line = addslashes($line);
$line = ereg_replace(9,"\\t",$line);
$line = ereg_replace(10,"\\n",$line);
echo $line, "BR";
pg_put_line($db,$line);
flush();
}
pg_end_copy($db);
and while the data was exactly the same format as the example, I managed to
get postgres stuck in COPY and had to manually kill the postgres COPY
process to recover.
Any one have any ideas?
Cheers,
Graeme
