I have read all over the place how WordPress is only capable of working on MySQL, which I have no problem with, however where I work we are on MSSQL, and MSSQL alone.

I read here:
<http://core.trac.wordpress.org/ticket/10918>

That there was at one point some stuff added to the code to potentially allow MSSQL functionality, I tried to work through some of the changes from that ticket, but got a little confused on some things.

Has there been any progress in making MSSQL available in the production code?

If not, what is the best way to implement the code from the ticket I listed above?

Appreciate the help!
