休眠條件與2個條件子句中1個查詢

Question

我如何acheive以下SQL查詢使用休眠條件查詢：

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

Answer 1

假設我們具有下面的代碼表2.關於表1標準和標準獨立工作完美：

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));
