Status: Open
Bug Type: MSSQL related
Operating system: Win2K
PHP Version: 4.0.5
Description: Odd MSSQL errors about 25% of the time

Yes, I can piece some together.  Most of the stuff is seperated into different files 
and classes so i'll just put examples of the database accesses in the order they 
happen.

I am using ISAPI with Apache 1.3.19 and MS SQL Server 2k on Win2k Server SP1.

Hope this helps.

/* db.inc.php */
        global $db_conn;
        $db_conn = mssql_pconnect ('localhost', '***', '***') or printf ('Cannot 
connect to SQL Server.');
        mssql_select_db ('demoXpress') or printf ('Cannot select demoXpress DB.');

/* class_menu.php */
if (!empty($this->Name))
{
        $sql = "SELECT * FROM Menus WHERE Name='{$this->Name}'";
        $rs = mssql_query ($sql);
        $this->Menu = mssql_fetch_object($rs);
        mssql_free_result($rs);
}

/* class_newsmachine.php */
$sql  = 'SELECT NewsID, News.SectionID, News.Poster, CONVERT(varchar(50), 
News.PostDate, 120) AS PostDate, ';
$sql .= 'Title, Teaser, DATALENGTH(Content) AS ContentLength, News.ViewCount, ';
$sql .= 'Sections.Name, Sections.Icon, ISNULL(MessageCount, -1) AS CommentCount ';
$sql .= 'FROM News, Sections, mb_Topics ';
$sql .= 'WHERE (News.CommentID*=mb_Topics.TopicID) AND 
(News.SectionID=Sections.SectionID) AND (News.FrontPage=1) ';
$sql .= 'ORDER BY News.PostDate DESC';

if (!($this->NewsRS = mssql_query ($sql, $db_conn))) echo mssql_get_last_message();

Could you provide some sample code ? And are you using CGI or ISAPI ?

Below is an example of the series of errors I get when loading a page on my website.  
What is odd about it is that the errors do not always occur.  About 75% of the time, 
the page works perfectly.  Then I'll refresh the page without even making any changes 
to the source and the errors will occur.  Refresh again and they disappear and the 
page works.

Another interesting occurance.  Sometimes, the first queries that are run will run and 
complete successfully, but then a query that comes later in the source on the same 
page will cause these errors.
