I have just setup a Sql Server db using the same mappings and source data that have been working with SQLite, and getting the error below when I try to save a batch of test data.
I suspect it is a hilo issue that SQLite doesn’t catch but I can’t quite get my brain onto it. I am using the SchemaExport tool to generate the database, which creates a hibernate_unique_key table that is initially ‘1’. After the error it is ‘2’
Any suggestions?
Cheers,

The problem doesn’t appear to be with your hilo table. That is behaving correctly from my experience using hilo key generation. According to the exception, you’re violating a unique key constraint for ActivitySubjects. Check your unique key constraints.
