I am developing a Java application using JPA for data persistence. In my application, I need to save a book description that often exceeds the default varchar(255) limit. To address this, I used the @Lob annotation on the book description field. However, when saving the entity to the database, I noticed that the description is stored as an integer representing the number of characters in the description, instead of storing the full text. I would like to understand what is causing this behavior and how I can fix it so that the description is correctly saved as text.
