nhibernate envers and optimistic concurrency

I am using nhibernate envers for auditing. creating a corrosponding audit table for each table in database.

Envers needs two fields mandatory: one version and another timestamp.

but version field is also needed in main table for optimistic concurrency.

lets say: TableA { id , version , name } then as per envers the audit table with have: { id, version, name, revision, revisionType }

the fields in audit table: version and revision would be exactly same, both contains the version of an entry.

If i remove the version field from main table, then optimistic concurrency will not work with nhibernate and for envers it is mandatory to specify a revision field.

how can i deal with this situation?

Solution

  • The Envers version and the Optimistic Concurrency version fields are different things. You should probably rename one or the other, if these are the default names.
