Hi all,
I have a parent object with child object.
In my parent mapping I have the following:
HasMany(x =>
x.Childs).Table("child_table").KeyColumn("ParentId").Cascade.AllDeleteOrphan().Inverse().BatchSize(100);
NH does correctly insert/delete the child records upon update of the
parent, but to achieve this, it does
1) select on the child_table
2) insert new child records (if any)
3) delete child records one by one (if any).
Especially this last part is concerning, if you have large child
collections.
What I want to do is:
1) delete all records from child_table by parent id.
2) insert all new records.
Is this possible?
Thanks,
Danny
