Description:
------------
When I use the mssql_fetch_object() function with a bit column, if the column has NULL value, the function returns 0.
 

Expected result:
----------------
I think the mssql_fetch_object function must returns null value (empty  value, same numeric columns when null the function returns "")

i have the same problem, my php version is 5.2.6 ans MSSQL 2000.
I see that the problem is mssql_fetch_array, mssql_fetch_row and mssql_fetch_object.  When you have a bit variable with null value those functions retuns cero, not NULL.
My problem has been resolved as simple sql query before a complete sql query final. by example.

$query="select * from table where column = '$column'  and Bit_Column is NULL ";
$qt=mssql_query($query,$dbhandle);
if (mssql_rows_affected($dbhandle)  <> 1)
{
header("Location: resumen.php");
}

Simple, but effective.
Regards Antonia.

With MSSQL being removed from PHP as of PHP7.0, and ext/mssql not having a maintainer, I'm gonna close this report as a Won't fix, until maybe one day it will find a new maintainer.

Alternatively you can use sqlsrv from Microsoft if you are on Windows, or pdo_dblib if you are on Unix.
