我有以下代码:
SQLSubQuery subQuery = new SQLSubQuery()
.from(qContentCache)
.groupBy(qContentCache.programId, qContentCache.id)
.orderBy(Expressions.stringTemplate("date").desc());
SQLSubQuery query2 = new SQLSubQuery()
.from(subQuery.list(subqueryProjection));
CollectionExpression<List<String>, String> subQueryExpression = query2.list(Expressions.stringTemplate("id"));
JPAQuery query = new JPAQuery(this.entityManager)
.from(qAsset)
.where(qAsset.id.in(subQueryExpression))
.orderBy(getJpqlOrderBy(orderBy));
当我尝试调用query.count()函数时,我得到以下异常:
java.lang.IllegalArgumentException: org.hibernate.hql.internal.ast.QuerySyntaxException: unexpected token: ( near line 4, column 6 [select count(c)
from com.irtve.plataforma.cms.model.Asset c

order by publication_date desc))]

但是,如果我尝试执行我得到的查询(在异常中给出),我没有错误。
有什么想法吗? 非常感谢您提前
答案 0 :(得分:0)
您的子查询使用与外部选择相同的表别名:
from com.irtve.plataforma.cms.model.Asset c
/* ... */
from com.irtve.plataforma.cms.model.views.ContentCacheView c
确保在实例化对表/视图“Q”对象的引用时提供唯一的别名:
QAsset qAsset = new QAsset("unique_alias");
