Question

I making a sample application with Hibernate. My requirement is that there is no primary key on the table. I had to do only select query from application. I know there should be a primary key, but the table I am referring has been made without it.

It has about 50k records. So, modifying the table to add ID column does not see viable option.

Can it possible?

Answer 1

1. Hibernate requires that entity tables have primary keys. End of story.
2. 50k records is simply not that many when you’re talking about a database.

My advice: add an autoincrement integer PK column to the table. You’ll be surprised at how fast it is.
