Error Saving and getting blob from database SQL oracle

Question

I\'m trying to save a CLOB into the database and recovering it, but I\'m getting an SQLException:

Caused by: java.sql.SQLException: Lob read/write functions          


        

Answer 1

I encountered a similar problem in one of the projects, setting

updatable = false

fixed the issue for me.

Example:

@Lob
@Column(name = "CONTENT", updatable = false)
Blob content;

Hibernate somehow tries to re-save the content, even when it was not changed.
