Hello,

I am trying to deal with update query using JPA. On the first page I allow user to upload their image which is byte[] in Person class. Then I can add this using entitymanager.persist() method. On the second page I would like to allow user to update their image with others data in Person class such as String name. My problem is with this byte array which I cannot put into this update query. What is the solution for update this type? I am using postgres so I have bytea type in my table if it has any meaning.

I really appreciate any help,
Michal

Why can't you put the byte[] into the query, what error do you get?
