Hibernate期待"全部",发现'加入'

Question

我越来越

QuerySyntaxException: expecting "all", found 'JOIN' near line 1, column 50 [SELECT p FROM com.rr.model.Person p FETCH JOIN p.positions pos WHERE p.id=:id]

Hibernate异常.将"JOIN"更改为"ALL"无效并产生以下错误:

QuerySyntaxException: expecting "properties", found 'p' near line 1, column 54 [SELECT p FROM com.rr.model.Person p FETCH ALL p.positions pos WHERE p.id=:id]

发生了什么以及正确的查询应该如何？

Answer 1

问题是我将语法切换为'FETCH JOIN'形成正确的语法:'JOIN FETCH'.正确的查询应如下所示

 SELECT p FROM Person p JOIN FETCH p.positions pos WHERE p.id=:id

'ALL'的正确语法如下所示:

SELECT p FROM Person p FETCH ALL PROPERTIES WHERE p.id=:id
