I have taken a DB dump from my dev database to QA database ( oracle) for testing. My application is a spring boot application and uses hibernate envers for auditing. I get above error when trying to insert data to the tables. I tried removing data from all the audit tables and revinfo table. But the issue is still there. Anybody has any idea on this?
Same error after updating the version of hibernate-envers for springboot3+. One quick solution for me was to (first backup) remove all tables related to audit + remove revinfo table and also the sequencer (revinfo_seq if you created some). Then let the ddl-auto property do the work by setting in application.yml
jpa.hibernate.ddl-auto: update
It creates all needed tables and sequencers by its needed definition, and after that inserts were committed.
I am trying to validate database schema before running any queries using jdbc template. So is there any way to identify schema changes before making any queries in spring programmatically?? Currently I am using spring boot 2 and hibernate 5.
Add this to the configuration file.
hibernate.hbm2ddl.auto=validate
If the value is validated then hibernate only validates the table structure- whether the table and columns have existed or not. If the table doesn’t exist then hibernate throws an exception.
Validate is the default value for hbm2ddl.auto.
In a project that I am working with Spring and JPA, I need to call a stored procedure but it does not have any table stored on the application side, only an input parameter is sent and returns an output parameter to know if I finish the process.
In all examples with JPA it always relates to JPA entities and the BD Tables.
Thank you for your contributions.
Take JPA out the pricture then. Assuming your application has a Datasource configured then inject that to the relevant code and get a connection:
https://docs.oracle.com/javase/7/docs/api/javax/sql/DataSource.html#getConnection()
Then just use standard JDBC.

I have created two spring boot microservices for experimenting purposes, both use hsqldb. Is there a way to see the hsqldb details like what is the name of the db that spring boot created, username, password, what tables are there in each one and to query those tables.
You can use the built-in SQL functions and INFORMATION_SCHEMA views in HSQLDB to check these properties. See the Guide http://hsqldb.org/doc/2.0/guide/
But the quick and easy way is to use a file: database connection and check the *.script file of the database, which contains SQL statements that set the properties and create the tables.
Am using Mysql database and hibernate in JPA. I have two mysql databases in my project. I want to configure these two databases in configuration class of spring JPA.
