Spring Boot HIbernate Issue: Error executing DDL via JDBC Statement with ddl-auto=create-drop

Question

I am a novice with Spring and Hibernate and have tried everything I could find to fix this with no luck. Any assistance would be greatly appreciated. I am currently following a sample project in a book, and am getting an error that says "GenerationTarget encountered exception accepting command: Error executing DDL via JDBC Statement." I am using a MariaDB database, and my hibernate dialect is org.hibernate.dialect.MySQL5InnoDBDialect.

The query causing this issue is

alter table car drop foreign key FK2mqqwvxtowv4vddvtsmvtiqa2;

If I try to run this query directly in the database it works fine. I have the ddl-auto property set to create-drop, so maybe it is trying to execute this query when the car table has been dropped and is not there? I'm not sure why it would do that or how to turn off this behavior if that is the problem.

If I change ddl-auto to validate or update, the application fails to run at all. If I change it to create, it works fine and I get no errors.

With create-drop, the application does connect to the database and all my tables are created. The tables are still defined as they should be, but the error remains.

Console output:

Here is the code on my repo: https://github.com/Kallaste/spring_login_server_example_so

Answer 1

I wouldn't worry about it if your application still runs. Hibernate throws a lot of 'informative' errors on startup. It just tries to figure out what it has to do to get the database in a state where your application can run.

If the app runs fine if you use create-drop or just create , then try running it with create just once so everything is generated and then change it to validate so the next time it only validates your database schema.

In a production environment you would generally not let Hibernate update the database schema by itself but manually apply changes and migrate data anyway, unless you're very sure the changes would be applied correctly.

Answer 2

You should use create the first time you run your application, but the next runs have to have update .

When you use create you create the schema and destroy the previous data. And create-drop destroy the schema in the end of the session. update only update you schema.

Answer 3

update should still be valid. If tables don't exist, it will behave as create.

Are you sure your DB and DBDialect match?

Answer 4

Add @Table annotation like below

@Table(name="car") in car entity. Always give name to table.

Note:

1) When ddl-auto=create-drop and if you don't have @Table(name="car") always you will get this exception.

2) When ddl-auto=create-drop and if you have @Table(name="car") the first time alone you will get this exception.

So try to change the ddl-auto value to other than create-drop. May be you can use "create" or "update"

Hope this helps.

Answer 5

Need to change spring.jpa.hibernate.ddl-auto = update instead of create-drop in application.properties file.
Because It is dropping the database at the start of the application and so it won't find the required events table to alter anything.

Answer 6

The problem is because you don't have permissions on the database user.
