If you are trying to run Sitefinity 4.4 on SQL 2012 you won't be able since this SQL version is supported after the 5.0 release, so all earlier versions of Sitefinity (3.x, 4.x) cannot be initialized with SQL 2012 version.
What I would suggest is to consider upgrading Sitefinity to the latest version.
All the best,
