Symptoms
Assume that you create an INSTEAD OF trigger that uses inserted or deleted tables in a contained database in Microsoft SQL Server 2012 or SQL Server 2014. Unexpectedly, you may find that the INSTEAD OF trigger uses a different collation than the collation that's used by the contained database.
For example, the contained database uses a case-insensitive collation and the INSTEAD OF trigger uses a case-sensitivity collation.
Cause
This issue occurs because the INSTEAD OF trigger does not use the DATABASE_DEFAULT collation for inserted and deleted tables in the contained database.
