Hi Folks, I am new in EJB, and have a question about how to load a null parent_id into its Entity bean. I have a table as follows: CATEGORY +---+---------+----------+ | |ID |NAME |PARENT_ID | | |1 |Computer |Null | | |2 |PC |1 | | |3 |Mac |1 |
I want to load the first computer row with null parent_id into entity bean Category, but I don't know how to create an em.createQuery("..."). Any help will be appreciated. Thank you in advance.
