Database sequence
A database sequence is a database object that generates an ordered series of numeric values, commonly for identifiers.
Java Persistence with Spring Data and Hibernate epub
A database sequence is a database object that produces successive identifier values independently of row insertion.
- How it is used
- Supplies entity primary-key values before deferred SQL INSERTs when a pre-insert generator is used.
- How deep it goes
- Explains generator configuration, native-sequence fallback, and identifier timing; does not detail database sequence internals.
- Examples
- Shows package-level @GenericGenerator parameters and Item persistence through EntityManager.persist and Spring Data JPA save.
- What you can do after
- Operate/configure it with a named Hibernate generator and choose a pre-insert strategy when identifiers are needed before INSERT.

A database sequence is a database object that generates an ordered series of numeric values, commonly for identifiers.
- How it is used
- Automates primary-key values while constructing and populating PostgreSQL tables with Copilot assistance.
- How deep it goes
- Defines start and increment settings, then shows default-value association; it stops short of deeper sequence internals.
- Examples
- Uses depreciation_strategy, funding_details, and assets tables with sequence-backed integer identifiers.
- What you can do after
- Operate/configure PostgreSQL sequences and attach them to table primary-key defaults after reviewing generated SQL.
