sqlsrv

I'm trying to debug Quiz and get it running on SQL Server, any help would be appreciated, new to drupal module maintenance, so don't know if this is spot for such conversation...

Quiz installed ok on SQL Server.

Cannot create 1st quiz record, crashes on SAVE. Confused about the quiz_save_properties() function where it crashes on the db_query.

On 1st quiz create, quiz_node_properties table is empty, so db_query will return null (if it didn't crash). The entity_save() would then save quiz with a qnp_id of null.

I have some questions about this scenario:

1 - If I distribute a development in drupal using MSSQL as Database Server (http://drupal.org/projects/sqlsrv) that is not under GPL licence, the functions and/or procedures stored in that database can be encrypted? Notice that in this case I didn't encrypt the drupal code.
2 - If I use Drupal to interact with data generated and managed from a propietary software (which can't be redistributed), can I via contract or other negate the possibility of a redistribution.

I just tried to create a sub-group using the Organic Groups module, and I received the same error that I received several months ago when I replied to an issue report on drupal.org. I found another related issue report referencing a possible fix, but the patch didn't work for me.

I'm not trying to stir the pot so-to-speak; I'm just trying to figure out why nothing's happening with what many see as an important issue with the SQL Server driver for Drupal 7. This driver is maintained by the Commerce Guys.

There has been a major issue with the update from Drupal 7.12 to 7.14 and 7.15 for several months that was noted on these two reported issues:
