Description:
------------
Connecting to a MSSQL server and selecting the server property "ProductLevel" results in PHP giving a warning:

> Warning: mssql_query(): column 1 has unknown data type (98)

According to MSDN[1] it has a "Base data type: nvarchar(128)".
The same warning happens with server property "Edition".

Happens on an MSSQL server ProductVersion "11.0.3128.0", Edition "Standard Edition (64-bit)", ProductLevel "SP1".

Test script:
---------------
test.php:
$link = mssql_connect($host, $user, $pass);
mssql_query("SELECT SERVERPROPERTY('ProductLevel')", $link);

/etc/freetds/freetds.conf:
[global]
tds version = 8.0
client charset = UTF-8

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.
