休眠中的查询错误：SQL 错误：156，SQLState：S0001

Question

运行时出现错误。请帮助我理解问题。 我正在使用微软的 sql server

@Query("SELECT p from Product p JOIN FETCH StoreProductAvailability as spaFirst JOIN FETCH p.colors c WHERE spaFirst.available = true AND spaFirst.colorId <> 'null' AND spaFirst.colorId is not null and spaFirst.storeId = :storeId AND p.id = spaFirst.articleId AND c.colorId in (SELECT spaSecond.colorId from StoreProductAvailability spaSecond WHERE spaSecond.available = true AND spaSecond.colorId <> 'null' AND spaSecond.colorId is not null and spaSecond.storeId = :storeId and spaSecond.articleId = spaFirst.articleId)")

Answer 1

问题是：

JOIN FETCH StoreProductAvailability as spaFirst

StoreProductAvailability 是 Product 的一部分吗？然后你会像p.colors. 那样做，比如join fetch p.availabilities。

还是完全不相关？然后你需要重写你的查询，因为你不能加入fetch不相关的实体/集合。更新：不过，您可以从 Hibernate 5.1+ 开始加入不相关的实体。
