Problem in Criteria

[Paras Jain]

Hi,
I am new to the criteria queries. Previously I have worked on some basic HQL queries.
I am having a problem in writing a criteria query

Here is the structure of my class

class C{
A a;
B b;
}

I want to write a query like this
select * from C where a.id="somevalue" and b.id="somevalue"

I want to achieve it in single query.

Currently I am doing this
First I am writing two different criteria queries to fetch instances of a and b and then I say

Criteria criteria = DetachedCriteria.forClass(C.class)
.add(Restrictions.eq("a", a))
.add(Restrictions.eq("b", b));


My question is - Is there any better way to do that, like getting it in a single criteria?

Regards,
Paras
