SQL Server 2012 not supported on WSS 3.0/MOSS 2007
In this post I would like to update you that SQL Server 2012 is not supported on WSS 3.0/MOSS 2007.
Moss 2007 supports only from SQL 2000 to 2008 R2.
Basically, the supportability of products is normally the minimum requirement + 2 versions, unless exceptions. Read here for further more about “SQL support to Sharepoint” –
Hope this helps.
