我认为Hibernate在DB2中呈现了错误的SQL?我当然犯了一个错误
我jpa代码是:
public List<Gc1glcostctrmap> findByCriteria(
Map<String, SortDirectionEnum> sortFields,
Integer start,
Integer length) throws Exception {
CriteriaBuilder builder = entityManager.getCriteriaBuilder();
CriteriaQuery<Gc1glcostctrmap> criteriaQuery = builder.createQuery(Gc1glcostctrmap.class);
Root<Gc1glcostctrmap> root = criteriaQuery.from(Gc1glcostctrmap.class);
int noDeleted = 0;
criteriaQuery.select( root )
.where( builder.equal(root.get(Gc1glcostctrmap_.g1011logdel), noDeleted) );
if ( Validator.isNotNull(sortFields) ) {
criteriaQuery.orderBy(_orderBy(sortFields, builder, root));
}
// create query
Query query = entityManager.createQuery(criteriaQuery);
query.setFirstResult(start);
query.setMaxResults(length);
// execute query
List<Gc1glcostctrmap> gc1glcostctrmaps = query.getResultList();
return gc1glcostctrmaps;
}
并且sqlshow为True,对于呈现的第一页:
select fields from BNGL.GC1GLCOSTCTRMAP gc1glcostc0_ where gc1glcostc0_.g1011logdel=0 order by gc1glcostc0_.g1136id asc fetch first 10 rows only
但是对于所呈现第二页:
select fields from ( select inner2_.*, rownumber() over( order by order of inner2_) as rownumber_ from
( select fields from BNGL.GC1GLCOSTCTRMAP gc1glcostc0_ where gc1glcostc0_.g1011logdel=0 order by gc1glcostc0_.g1136id asc fetch first 20 rows only ) as inner2_ ) as inner1_ where rownumber_ > 10
order by rownumber_
最终错误是:

您可以使用自定义Dialect,因为Hibernate DB2Dialect中生成的查询不正确。请参考以下答案:db2-with-pagination
