I experience the same problem with php 5.0.5, win2k, not sure what
version of sql server. As a temporary fix, you can change your code to
use mssql_connect instead of pconnect, that seems to solve the problem
for me.

Description:
------------
I am using IIS6 (Win2k3 Server, SQL Server 2000, PHP 4.3.4 DLL)
I am connecting to MSSQL using username/pwd and pconnect
no probs there.
My problem is that if I execute a horribly incorrect SQL statement one
of the perminant connections to MSSQL is disabled giving 'unable to
connec to database' (pconnect() == false) errors 50% of the time..
For example:
Table: [Stock Items]:
StockItemID int no nulls identity
SupplierID int no nulls <--**
test varchar(50) allow null
...
$sql = "INSERT INTO [Stock Items] (test) VALUES ('this should fail')";
$result = mssql_query($sql);
Warning: mssql_query(): message: Cannot insert the value NULL into
column 'SupplierID', table 'Database Name.dbo.Stock Items'; column does
not allow nulls. INSERT fails. (severity 16) in
C:\Inetpub\websites\sitename\public_html\acweb\includes\functions\database.php
on line 49
Warning: mssql_query(): message: The statement has been terminated.
(severity 0) in
C:\Inetpub\websites\sitename\public_html\acweb\includes\functions\database.php
on line 49
Warning: mssql_query(): General SQL Server error: Check messages from
the SQL Server. (severity 5) in
C:\Inetpub\websites\sitename\public_html\acweb\includes\functions\database.php
on line 49
Warning: mssql_query(): Query failed in
C:\Inetpub\websites\sitename\public_html\acweb\includes\functions\database.php
on line 49
Warning: mssql_query(): Attempt to initiate a new SQL Server operation
with results pending. (severity 7) in
C:\Inetpub\websites\sitename\public_html\acweb\includes\functions\database.php
on line 186
The last error is the one that is the kick in the guts as now EVERY sql
statement until the page finishes loading will fail.
When the page is refreshed pconnect() will work 50% of the time (if
they get a valid connection it works, if they get the dead connection
it fails).
The only way I can fix this problem is restarting IIS which is a pain.
I can replicate the problem by killing the process from MSSQL
Enterprise manager.
Any help would be great.
ps. an answer of "just fix your sql statement" is not what I'm looking
for as it is not allways related to invalid sql statements, running
large querieis using ODBC over the www seems to cause the exact same
problem, so does re/syncronizing a large replicated sql database.
Thanks.
Reproduce code:
---------------
Table: [Stock Items]:
StockItemID int no nulls identity
SupplierID int no nulls <--**
test varchar(50) allow null
...
$sql = "INSERT INTO [Stock Items] (test) VALUES ('this should fail')";
$result = mssql_query($sql);
Expected result:
----------------
$result == valid mssql result
Actual result:
--------------
Warning: mssql_query(): message: Cannot insert the value NULL into
column 'SupplierID', table 'Database Name.dbo.Stock Items'; column does
not allow nulls. INSERT fails. (severity 16) in
C:\Inetpub\websites\sitename\public_html\acweb\includes\functions\database.php
on line 49
Warning: mssql_query(): message: The statement has been terminated.

+ dead pconnection to MSSQL server until IIS (php dll) is restarted
