DB2 Hibernate temporary tables cannot be accessed

Solution Verified - Updated -


  • How can we ensure temporary tables are available during statement execution when required?
  • Currently facing problems with Hibernate 5 accessing temporary DB2 tables 1. These tables are used internally by hibernate e.g. in the context of entity deletion (using a mechanism called MultiTableBulkIdStrategy which is implemented by GlobalTemporaryTableBulkIdStrategy in the Hibernate DB2Dialect)
    While this works with Hibernate 4 and our application, the temporary tables cannot be accessed with Hibernate 5.
    Instead of accessing the temporary tables, table names are prefixed with SESSION.HT_, Hibernate 5 tries to access "real" schema tables which of course does not work, as these tables (as well as the schema SESSION) do not exist.
