Question

我在sql后面有以下HQL ..

SQL ....

SELECT * FROM POS_took WHERE DELETEDDATE IS NOT NULL

它对应的HQL是......

session.createQuery("from postook where deleted is not null")

和java Entity类是......

class postook
{

//all the properties defined here 

private DateTime deleted;

//and it corresponding setters and getters is defined.

现在请告知上述HQL的等效标准表示

Answer 1

Criteria criteria = getSession().createCriteria(postook.class);
criteria.add(Restrictions.isNotNull("deleted"));
