Re: [PHP-DB] mssql datetime field
Hi,
there exists a workaround in php for this problem. Just put in your php.ini:
mssql.datetimeconvert = 0
or in your script:
ini_set('mssql.datetimeconvert' , 0);
this causes date values in this format: -MM-DD HH24:MI:SS
if it doesen't work correctly, the upgrade to php4.2.1
bye,

has anyone had any expierence with the datetime field coming back from

happens
to me no matter the time in the database. PHP inserts it correctly, but
the select has a problem. I am using php4.1.2 and SqlServer 7.0.
Or is anyone haveing success, in new versions of PHP. Upgrading PHP
is no
problem, upgrading SQL is not an option
Thanks in advance.

[PHP-DB] Problems mssql_get_last_message()
Hi,
I have problems with mssql_get_last_message(). This function doesen't
return the whole error message, it only returns Die Anweisung wurde
beendet and not the specific error message. Now I use something like
this to workaround the problem:
... snip ...
$this-errno = mssql_result(@$this-priv_query('SELECT @@ERROR as
errorcode', $this-dbc), 0 , 'errorcode');
$this-error = mssql_result($this-priv_query(SELECT description FROM
master.dbo.sysmessages WHERE error=$this-errno and msglangid = 1031,
$this-dbc), 0, 'description');
$this-error = str_replace ('%', '%%', $this-error);
but the problem is, that I get the error message with placeholders (not
parsed):
Die %1!-Anweisung verstieß gegen die %2! %3!-Einschränkung '%4!'. Der
Konflikt trat in der %6!-Datenbank, Tabelle '%8!'%10!%11!%13! auf.)
are there any hints to get mssql_get_last_message() to work?
bye,

Re: [PHP-DB] blob versus file
Hi, one point that you should keeped in mind is, if you have a cluster of webservers connecting to the same db-server, then you have to mount the filesystems, where you store the images on all webservers. On the other hand many db's like oracle have many restrictions with lobs. In oracle you can have only one LOB per table. And also functions like SELECT DISTINCT or GROUP BY are not supported on LOB-fields. MySQL is here the positive exception, because MySQL supports such functions also on LOB-fields. We store images and other documents on the filesystem, but text-data like session-data ist stored in LOB's, bye, Pierre-Alain Joye schrieb: On Tue, 2 Jul 2002 05:45:40 +0200 Andy [EMAIL PROTECTED] wrote: is the increase of the network traffic noticable?

[PHP-DB] PHP looses Resource-Id's
Hi,
I found a bug in php4.2.1 (Windows XP, IIS with php as CGI).
- I have a db-class wich stores the resource-id of a db-connection.
- I have a function (itk_new_db) where I return an object of the class
above and I remember this object in a static-var.
- the second call on that function (itk_new_db) returns the same object,
but the resource-id is lost!?!?!?
This nice feature also exists with com-objects. This seems to be a cool
bug in the resource-manager of php.
Any hints? If not I make a bugreport.
class db_class {
var $dbc = null;
function connect() {
$this-dbc = mssql_connect('wincubix', 'oebb', 'oebb');
//
$this-dbc = mysql_connect('localhost:3308', 'root', '')
}
}
function itk_new_db(){
static $db;
if (!isset($db)) $db = new db_class;
return $db;
}
$db1 = itk_new_db();

returning references from functions only works if you have on

Re: [PHP-DB] Re: Maximum field length with PHP 4.1.2/MSSQL v7 ?
Hi, now I rewrote my PHP-DB-Module using COM and ADO (OLEDB), it works well, the 255 Bytes limitation doesen't exist with this method, but uff it takes a lot of memory, after openening the db-connection, the php-process increases his memory usage with about 4 MB, this seems to be a problem of COM (big overhead). But on the oder hand, if microsoft propagates this as the only method to access MS SQL, then its a problem of those customers who uses microsoft products. bye, Michael Bretterklieber wrote: Hi, I ran into the same problem, but the problem I have is that I can't switch to TEXT Datatype because MSSQL doesen't support SELECT DISTINCT or GROUP BY on them.
