HIbernate 条件构建器和 if 条件

Question

SQL QUERY:

SELECT SUM(IF(table.type='type1', 1, 0)) as type1,SUM(IF(table.type='type2', 1, 0)) as type2 from table;

How to write same query in criteria builder like below:

CriteriaBuilder builder = entityManager.getCriteriaBuilder();
CriteriaQuery<Object[]> criteria = builder.createQuery( Object[].class );
Root<Table> root = criteria.from( Table.class );
criteria.multiselect(builder.sum())

I am unable to place if condition in criteria builder.

Note: there is bean class for Table. Thanks in advance.

Answer 1

Apparently hibernate criteria does not support IF . I would consider just making 2 queries with criteria or using HQL or just native SQL.
