David Good commented on HHH-3326:
---------------------------------

The older versions of the attachments should disregarded - they will cause a failure if any of the temporary table's columns is not of the *char variety.

> The use of temporary tables for updates in SQLServer will fail if tempdb uses a different collation to the application db.  Specifically, comparisons between the primary table columns and the temporary table columns fail.
> It is unclear to me under what circumstances a temporary table is created, so I'm afraid no test case is attached.  I do however attach modified versions of the following classes:
> org.hibernate.mapping.Table
> org.hibernate.dialect.Dialect
> org.hibernate.dialect.SQLServerDialect
>   
> These resolve the issue, but the solution may not be the most optimal possible, as it involves intervention in a specific position (between the datatype declaration and any nullability clause)
