 Operating System: Windows 2000 Server SP2
 PHP Version:      4.3.0
 New Comment:

Well the nature of CGI doesn't really lend itself to supporting
persistant connections.  It's run when requested and then exited after
that.  So no data can really presist between pages that exists solely
in the CGI.  

So this behavior only exists when odbc.check_persistent is turned on?

Yes still a problem under 4.3.0 I am using the ISAPI module. I don't
believe that persistent connections are supported at all under CGI. So
odbc_pconnect == odbc_connect which would give the illusion of working,
although the connection would not actually be persisting.

The first time you reload the page after killing the database
connection you get:

Warning:  SQL error: No response from the backend;

Subsequent reloads give:

Warning:  SQL error: Could not send Query(connection dead);

Thank you for taking the time to report a problem with PHP.
Unfortunately you are not using a current version of PHP -- 
the problem might already be fixed. Please download a new
PHP version from http://www.php.net/downloads.php

If you are able to reproduce the bug with one of the latest
versions of PHP, please change the PHP version on this bug report
to the version you tested and change the status back to "Open".
Again, thank you for your continued support of PHP.

Not saying this is bogus but can you try the release version just to
make sure?  

I did test this on a win2k build recently and found it to work under
CGI.  how are you running this?

I'm unable to reproduce this on the UNIX end of things.  Anyone with a
Windows boxen working that can test this?

Make sure the odbc.check_persistent is on and that
odbc.allow_persistent is on. Set up a database connection called
dsnname
Run the script below (substituting [tabname] for a valid table name in
your database).
Check that you have persistent connections, ie with the webserver idle
make sure your database shows connections from the webserver.

Restart the database or kill the session belonging to the web server.

Re-run the script below and the odbc_exec fails with an error: 
"connection not open"  or smililar depending on your odbc driver.
I have found this effect to be the same with the Postgres odbc driver
and the Informix 3.30 odbc driver.

I presume that odbc.check_persistent is supposed to check that the
connection is still attached to the database before pconnect gives it
to the script?

<?
$dbconn = odbc_pconnect("dsnname","","");
$rid = odbc_exec($dbconn,"select * from [tabname]");

?>
