[hibernate-issues] [Hibernate-JIRA] Created: (HHH-3326) Temporary tables created in SQLServer use the collation for tempdb, not the application database

[David Good (JIRA)]

Temporary tables created in SQLServer use the collation for tempdb, not the application database
------------------------------------------------------------------------------------------------

                 Key: HHH-3326
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3326
             Project: Hibernate3
          Issue Type: Patch
    Affects Versions: 3.2.4.sp1
         Environment: SQLServer (All versions)
            Reporter: David Good
         Attachments: Dialect.java, SQLServerDialect.java, Table.java

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)
