RE: [PHP-DB] MS SQL 'Changed database context' error

2004-02-22 Thread Michael Flanagan
Robert,

Believe it or not, it's a simple SELECT statement!  (I'm not even aware
that I'm changing context, nor exactly what that means.  I thought that
if I used the same $db resource, things would be fine.)  Other SELECTs work,
but
not this particular one!  Here's the script (the FindInDb function below
has, of course, been called from a prior script):

/**
 * Find the record in the db that matches the Encounter info.
 *
 * If $updateObject is TRUE, then we update the object's fields with
 * values from the matching record in the database record.
 */
function FindInDb($db, $updateObject, $errStr)
{
global $DbOwner;// null string () for MS Sql Server

if (!IsSet($this-_deviceId) || !(IsSet($this-_timeStart))) {
$errStr .=
  Encounter::FindInDb: either _deviceId or _timeStart is
NULL.;
return FALSE;
}

$sql = SELECT * from {$DbOwner}Encounter  .
   WHERE (Device_key = $this-_deviceId) AND  .
 (Time_start =  .
 ToDate($this-_timeStart, -MM-DD HH24:MI:SS) . );
if (!UseOrOpenDb($db, $closeDb, $errStr))
return FALSE;

$result = GetInfoFromDbHelper($db, $sql, $errStr);

and so on.

The routine UseOrOpenDb looks at $db to see if it's a valid
$db connection.  If not, it opens a new one.  I've determined
that FindInDb is always passed a valid $db, so UseOrOpen doesn't
open a fresh one.

/**
 * Determine whether a db resource is already open; open one if not
 *
 * In many places we pass a $db resource to a routine.  That resource might
 * not be open, in which case the called routine should open the db.
 */
function UseOrOpenDb($db, $dbOpened, $errorString)
{
if (!$db) {
if (!($db = GetDbConnection ($errorString))) {
return FALSE;
}
$dbOpened = TRUE;
}
else {
$dbOpened = FALSE;
}
return TRUE;
}

GetInfoFromDbHelper simply executes the SQL string:

function GetInfoFromDbHelper ($db, $select, $errorString)
{
// Get info, based on the $select query
$result = $db-query($select);
if (DB::isError($result)) {
$errorString .= $result-getMessage() .
  $result-getDebugInfo ();
return FALSE;
}
return $result;
}

Hi Michael

Can I see the script you are using that causes the problem?  When I change
the database context using the mssql extension under PERA it is not a
problem.

The PEAR DB drivers suppress all messages generated by their underlying
extensions.  The mssql DB driver will only stop if the mssql ext function
it calls fails.  Since changing the database context should not cause a
function to fail, I am not exactly sure why your script is stopping.

 The MSSQL standard mssql extension handles the 'Changed database context'
 message correct.

 Each query send to the SQL server results in some form of message
 returned. This can be either an error message or an information message.
 The MSSQL extension uses two ini settings to tell PHP how to handle these
 messages. If a message from the server has a severity equal to or higher
 than the setting in php.ini, PHP will create a warning or an error (stop
 processing the script).

 The default setting for both parameters is 10, and that should give a
 smooth execution of most PHP scripts. For debugging you might want to
 lover these values. (And this is not what I said in an earlier post but I
 was wrong then. This time I checked it :-))

Hi Bob,

Problem solved!  In the process of looking around, to ensure that I wasn't
switching db's, I found that the second SELECT I was doing was using an
empty
select string, as opposed to SELECT * FROM...  I fixed tha blunder, and
things
started working.

I'm never quite so stupid as when I'm trying to be quite so smart!

Thanks for sticking with me on this one.

Hi Michael

Prior to executing a query with the PEAR mssql DB driver, the driver will
always call mssql_select_db().  The db that was specified in the DSN is
the one that is selected.  If the db is changed after connecing via a
query, i.e., use AnotherDB, this will cause a problem if the context is
changed back to the original DB.  Are you changing the DB after
connecting?

 You might get better results using the odbtp extension with support for

You are getting a message from the SQL Server.

If you increase the values of mssql.min_error_severity and
mssql.min_message_severity (default is 10) you will get more messages if
you descrease the value you will get less messages.

Hi Michael

You might get better results using the odbtp extension with support for
the mssql functions. Since you are using Windows, use
php_odbtp_mssql.dll instead of php_mssql.dll.

 Adam,  Thanks for the suggestions.  I don't want to ignore all error
 handling.  Later, I might get an error that I really don't want php to
 swallow due to either of your suggestions.

 Has anyone else run into this and solved it?

 Any idea why the following lines in the php.ini file don't work?
 mssql.min_error_severity = 11
 mssql.min_message_severity = 11

 Michael

 Try putting the error suppressor (@) before the query, eg:

 @mssql_query

 Or, try setting the error reporting:

 error_reporting(0);

  I don't get the error in Enterprise manager.  MS has a KB article out
that
  says that this message is informational.  I seem to remember that the
  article also says the message comes out some times, and not other times,
 but
  that you should just forget it.
 
  The particular SELECT statement I'm getting the message on is the second
  query in my script.  The other query is to the same db; in fact, it uses
 the
  exact same $db connection object.
 
  Any ideas on getting PHP to ignore this info message?
 
  Thanks again.
  Michael

  This may not be the case, but I've seen this before when the PHP library
  didn't know how to express MS SQL's error, so it simply returns the last
  message sent which was the informational context change. If it is infact
  an error, you should be able to plug the query directly into Enterprise
  Manager to see MS SQL's take on the problem, so to speak. =)
 
  But again, this is all just in my past experience's, yours may differ
  greatly.

   mssql.min_message_severity = 11
  
   but to no avail.  What am I missing?  I don't mind the message so
much,
   but php treats this as an error, and doesn't execute my query.
  
   I'm running php 4.3.3 for Windows; the SQL Server and web server are
on
  the
   same machine.  I'm using PEAR:DB for the database access.
  
   Thanks.
