이 HQL에 무슨 문제가 있습니까? "노드의 데이터 유형 없음"
문제
session.createQuery("Select attribute from GoodsSection tgs " +
"join gs.ascendants ags join ags.attributes attribute " +
"where attribute.outerId = :outerId and tgs = :section ")
.setString("outerId", pOuterId)
.setEntity("section", section)
.setMaxResults(1)
.uniqueResult();
나에게는 괜찮아 보이지만 결과는입니다
java.lang.IllegalStateException: No data type for node: org.hibernate.hql.ast.tree.IdentNode
\-[IDENT] IdentNode: 'attribute' {originalText=attribute}

왜요? 뭐가 문제 야?
해결책
"GS"별칭을 정의하지 않았습니다. "AGS"와 "TGS"만 있습니다.
