(My real scenario is slightly more complex than that but that's where I am stuck...

MySQL....
Select u from User u where u.birthDate between :minDate and :maxDate
Setup the the minDate and maxDate of handling date arithmetic.
Then use the below HQL.
Calculate the birth dates corresponding to the min and max ages.

I'm trying to convert the below SQL query to HQL and am having a few issues. A straight line by line conversion doesn't work, I am wondering if I should be using an Inner Join in the HQL?

That said, Hibernate allows you.
Typically you HQL joins are specified using the property on the object, eg, if class Foo and Bar, there's no way of performing a self-join in HQL (I could be wrong here).

I'm looking for a builder for HQL in Java. I want to get rid of things like:
StringBuilder builder = new StringBuilder() .append("select stock from ") .append( Stock.class.getName() ) .append( " as stock where stock.id = ") .append( id );
I'd rather have...

For example, you cannot do more than one join over qb.append("("); qb.and("pt.details.creationTime... .
It automatically, if and only if you've got the mapping between Stock and Bonus setup and if bonus not provide all functionality avaiable in HQL.

Edit: This is not a conflict on the theoretical level but a conflict on an implementation level.
Another Edit: The problem is not having domain models as data-only/DTOs versus richer, more complex object map where Order has OrderItems and some calculateTotal...

Shades of gray between having an "anemic domain model" and cramming all of your services into your the boundaries between methods and operations should lie, and, what's more, how to implement look something like:

I need to use year() and month() functions in Criteria API to be able to express a business filter constrain. Expressions like

Would something like this work for you?
cri.Add(Expression.Ge("Duration.DateFrom", new Date(fromYear, 1, 1)); cri.Add(Expression.Le("Duration.DateTo", new Date(toYear, 12, 31));
Note that I changed your expression order -- I'm assuming you....

为什么不用面向对象的方法，把有关查询结果的数目，页码，当前页和结果集封装成一个类，条件页可以封装成一个类，这样不是更好 用 MAP 的话 个人觉得更直接，以键值的形式获取 取值更方便 很有想法啊，嘿嘿，看着不错啊 如果需要动态SQL，用模板语言就搞定了；如果需要自定义类来解析，抽象出一个通用性的where类就OK了~ 用模板语言终归还是要手写ifelse,要自动化才好啊.

First the basic facts: Java webapp, Spring, Hibernate, MySQL.
The situation is that I have a complex object model of e.g. a Car . It's composed of many objects (Engine, Tires, ...) with many-to-one and one-to-many relationships between them.
Now there...

Could do the exact opposite

I know, it's HQL not Criteria, but that's what I'm more fluent with.
