删除休眠（HQL）中两个表之间的关系

Question

I have two tables (Resources & Tags) and the third that connects both of them(Resources_tags). How can I delete the many-to-many relationship of a resource with several tags with a HQL query? For example, I want to delete all the tags that a resource have in Resources_tags table.

Answer 1

If your two tables are "A" and "B" then when you set up your two tables you need to specify "cascade" on table "A".

like this:

<bag name="A"
  inverse="true"
  lazy="false"
  cascade="all">
  <key column="SOME_ID"/>
  .....

Now any deletes performed on "A" should have the desired effect.
