With a simple Parent -> Child relationship, with an ordered OneToMany (List).
No updates are made to the @OrderColumn if *updatable = false* is specified on the @JoinColumn and changes are made to the List (e.g. order change, or removal from middle of the list).
I specify
@OneToMany(cascade = CascadeType.ALL, orphanRemoval = true, fetch = FetchType.EAGER)
@JoinColumn(name = "parent_id", nullable = false, updatable = false)
@OrderColumn(name = "child_index", nullable = false)
private List<Child> children = new ArrayList<>();
because
* The child's lifecycle is linked to the parent
* The parent should never update
* I want to avoid unnecessary _update Child set parent_id=?, child_index=? where id=?_ on inserts
But it seems it is affecting the update of the OrderColumn
* Here is the test-case *
