Explain the Core Concept:

This error message suggests that there is a missing table named ‘hibernate_sequence’ in the database with the name ‘DBNAME’.

Hibernate uses this table to generate unique identifiers for entities.

Different Solutions with code samples:

1. Check Spring Boot configuration to ensure that hibernate.ddl-auto is set to update or create in application.properties or application.yml file:

spring:
  datasource:
    url: jdbc:mysql://localhost:3306/DBNAME
    username: username
    password: password
  jpa:
    hibernate:
      ddl-auto: update

2. Manually create the hibernate_sequence table in your database using the following SQL query:
“`sql
CREATE TABLE hibernate_sequence (
next_val BIGINT
);
INSERT INTO hibernate_sequence VALUES (1);

3. If you are using JPA with GenerationType.IDENTITY strategy, you can remove the GenerationType.IDENTITY and manually assign the primary key value in your code.

Conclusion:

The error indicates that the hibernate_sequence table is missing in the database.

By checking and adjusting the Spring Boot configuration, manually creating the table, or changing the GenerationType strategy, you can resolve the issue.
