@GeneratedValue Strategies (AUTO vs IDENTITY vs SEQUENCE) ✅ #backend #ielts #javaframework #coding

@GeneratedValue is a JPA annotation used with @Id to auto-generate Primary Key values.

In this short video, you’ll learn:
• Why we use @GeneratedValue with @Id
• What “auto generated IDs” means in Hibernate
• Common strategies:
- AUTO (provider decides)
- IDENTITY (DB auto-increment)
- SEQUENCE (uses DB sequence)
• Where it’s used in real projects (User, Task, Project tables)

Interview Tip:
Use IDENTITY for MySQL auto-increment and SEQUENCE mostly for PostgreSQL/Oracle.
