Using Oracle squence in Hibernate
posted 3 years ago
I want to use an Oracle sequence with hibernate.
the problem is that the sequence will not be use as an ID. But to update a field when some conditions are available.
so I want to do something like this:
update MY_TABLE set NUM_VAL = select MY_SEQ.nextval
I found many examples but all of theme are talking about a sequence that is user as an ID:
<id name="id" type="java.lang.Integer"> <column name="ID_PRODUCT" /> <generator class="sequence-identity" > <param name="sequence">PRODUCT_ID_SEQ</param> </generator> </id>
I agree. Here's the link:
