I am using nhibernate and I have a question.

Say I have an object(ObjectA) that has some relationship to another object(ObjectB).

ObjectA -> TableA
ObjectB -> TableB

Now I do a query and get back results from TableA and now it’s in ObjectA.

If I did this

int b = ObjectA.ObjectB.ColumnA;

it would go off and fire a query right? Since it is doing lazy loading.

what happens if I did this

int b1 = ObjectA.ObjectB.ColumnA;
int b2 = ObjectA.ObjectB.ColumnA;
int b3 = ObjectA.ObjectB.ColumnA;
int b4 = ObjectA.ObjectB.ColumnA;

this is all in the method method one after another. Would you go and do 5 queries or would it just do one?

How about if I did this

  int b1 = ObjectA.ObjectB.ColumnA;
  string b2 = ObjectA.ObjectB.ColumnB;

would this fire off 2 queries or one?

All those methods result in just one call, to load ObjectB.

After that, it’s in memory; why would it go to the DB again?
