Oracle treating empty string as NULL problem for a Java / JPA programmer

Question

How do you handle this situation where Oracle stores the empty string as a null in the database ?

I would like it to be stored as an empty string as it is not as NULL, s

Answer 1

Its early for me, but isn't

select * from mytable where myfield like '%' or myfield is null

the same as

select * from mytable

So, Oracle simplifies your life! ;)
