1条查询中有2个条件的子句中的休眠条件

Question

如何使用Hibernate Criteria Query实现以下SQL查询：

select * from Table1 where (A,B) in (select A,B from Table2)

Answer 1

Assuming we have Criteria for Table 1 and Detached Criteria for Table 2. This below code work flawlessly:

Criteria criteria = new Criteria(Table1.class);

DetachedCriteria dc = DetachedCriteria.forClass(Table2.class); 
ProjectionList projList = Projections.projectionList();
projList.add(Projections.property("column1"));
projList.add(Projections.property("column2"));
dc.setProjection(Projections.distinct(projList));

criteria.add(Subqueries.propertiesIn(new String[]{"column1","column2"}, dc));
