(SF bug #495059)
- SQL file separated into database_schema.sql, for creating the schema,
clean-database.sql, which removes tables, views etc. from an existing
DSpace database, and update-sequences.sql which resets the ID generators,
but is only used after an SQL dump which sets explicit primary keys.
- Sequences for primary key generation added to SQL schema
- SQL function "getnextid" added as an abstraction for access to those sequences
- Database manager now uses getnextid() SQL function to get IDs - this means
other DB backends can hide ID generation specifics behind this
- Minor tweak to HistoryManager, which was accessing DB manager's in-memory
ID generator directly - now it doesn't do this.
- Old, now unnecessary "reset ID generator" admin servlet/JSP removed
