When trying to query a table, with a column whos type is 'smalldatetime', the code will result in a 500 Internal Error

Reproduce code:
Create table with the following columns

|(int) ID | (smalldatetime) MY_EXAMPLE |

$result = mssql_query("SELECT MY_EXAMPLE FROM MY_TABLE");

When you run that, you will get a:
500 Internal Server Error

On ArchLinux/Windows

Expected result:
No 500 Internal Server Error.

Should be able to query the database with no problems

Actual result:
500 Internal Server Error

I have run the same query on Windows Server 2003 (Enterprise Edition) and this does not seem to be an issue. On windows it is able to fetch the column data with no problems.

Always repeatable.

This is an issue for us as well. The previous comment is from a Windows user so they're probably able to leverage more native Windows MSSQL libraries...

PHP 5.2.11, on Linux, using FreeTDS on CentOS 5.3 (or 5.4, not sure) x86_64

The workaround is having to cast the column inside of the query. I will try to post an example workaround query when I grab one from the dev team.

Related Packages/versions of the driver, just in case:
unixODBC-2.2.11-7.1 (32 bit)
unixODBC-2.2.11-7.1 (64 bit)
unixODBC-devel-2.2.11-7.1 (32 bit)
unixODBC-devel-2.2.11-7.1 (64 bit)

Sample query/workaround:

old: SELECT acct_itm.cre_dtm AS cre_dtm
new: SELECT CONVERT(varchar(10),acct_itm.cre_dtm,120) AS cre_dtm

Not the most ideal. Might be a bug in the FreeTDS driver and not something PHP can handle but has to pass upstream.

Same bug here.
I'm using Ubuntu with php 5.2.6 and debian with php 5.2.12.

PHP 5.2.4 / ubuntu 8.10LTS has this bug and is reproducable.

Suhosin patch reports canary mismatch if a query returns smalldatetime.

Apache does not trigger 500, nor does PHP report any error to the page - it dies silently.

As described in comments,

mssql.datetimeconvert = Off
in php.ini fixes the issue!

Also get this in PHP Version 5.3.2-1ubuntu4.14.

mssql.datetimeconvert = Off
to php.ini does allow it to work.

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.
