Question

Say I have Table A that has many Table B’s. Table B has only one Table A.

Now say Table B has a property called Name. How can I do the following in linq.

Get all Table A’s where Table B has Name == “bob” then get all Table B’s inside table A.

Example

Table B
Name   TableA_Id
bob    1
bob    1
bob    1
jim    1
jon    2

So if I would a query I would want one Table A object back with 3 Table B objects within it.

I tried

session.Query<TableB>().where(x => x.Name == "bob").select(x => x.TableA)

session.Query<TableA>().where(x => x.TableB.where(d => d.Name == "bob") // can't do this since it is a collection 

I can’t do either of these as it either does not compile or it returns To many TableA (I think) what is giving me unexpected results.

I believe you can do:

var tableBs = session.Query<TableA>()
                     .Where(a => a.TableBs.Any(b => b.Name == "bob"))
                     .SelectMany(a => a.TableBs);
