In this article, Im going to explain how you can get a JSON property value using the -> PostgreSQL operator. Hibernate 6 provides a standard mapping for entity attributes to JSON columns you only need to activate it. If you want to use a JSONB column with Hibernate 6, I have great news for you. How JSON Works in PostgreSQL We need to make sure the given data is in a valid JSON format before adding it to the table. The first operator -> returns a JSON object, while the operator -> returns text. But you are probably already aware of that if you read this post. PostgreSQL has two native operators -> and -> to query JSON documents.

You can use the ref function from the main module to refer to json columns in queries. PostgreSQL supports two types of JSON columns: JSON and JSONB. You could, of course, store the JSON document in a text column. One example is PostgreSQL’s JSONB data type which allows you to store JSON documents efficiently in a database column. Most databases offer many proprietary features besides the known SQL standard. It actually has two JSON data types, json and jsonb.

PostgreSQL is an awesome database, with an awesome data type, JSON. The Persistence Hub is the place to be for every Java developer.
