我在现有数据库中有复合键的表。当我想在HQL中使用批量插入时，如＆＃34; INSERT INTO entityName（id.key1 id.key2，property1，property，...）SELECT prop1，prop2，prop3，prop3 FROM entityName2＆＃34;我收到错误：引起：org.hibernate.QueryException：无法解析属性...
如果我的＆＃34;插入＆＃34; -statement的实体只有一个id-column，那么一切都像魅力一样。
我使用hibernate-entitymanager版本4.3.6。
首先是insert-clause的实体：

我的select-clause实体。我分别测试了select-clause，它没有问题。

有没有办法在hibernate中使用bulk-insert和composite-key？
答案 0 :(得分：0)
作为一种变通方法，您应该将composite-id属性直接添加到实体并将其设置为insertable = false and updateable = false。无需为该属性添加getter / setter。
@Column(name = "F_DMP_FALL_NR", insertable = false, updateable = false)
private String DmpFallNr;
插入select 批量操作不会检查此选项。现在，您可以删除id前缀并直接在HQL查询中使用这些属性。
INSERT INTO Dm1Dap (idmpFallNr, anr, versNr, kassenNr) SELECT f.id.DmpFallNr, f.id.Anr, f.VersNr, f.KassenNr FROM Dm1F f
