Can I setup JPA/hibernate to persist Boolean types as Y/N? In the database (the column is defined as varchar2(1). It currently stores them as 0/1. The database is Oracle.

In JPA the object id is defined through the @Id annotation and should correspond to the primary key of the object's table. An object id can either be a natural id or a generated id. A natural id is one that occurs in the object and has some meaning in the application.
@Column. Let's start with the @Column annotation. It is an optional annotation that enables you to customize the mapping between the entity attribute and the database column.
Hibernate has a built-in "yes_no" type that would do what you want. It maps to a CHAR(1) column in the database.
Basic mapping: <property name="some_flag" type="yes_no"/>
Annotation mapping (Hibernate extensions):
@Type(type="yes_no") public boolean getFlag(); If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
