Answer 1

在内部，当在版本化实体上发出删除请求时，似乎Hibernate也将版本号作为第二个参数传递。因此，您需要修改SQLDelete语句以接受version参数。

实施例

UPDATE response SET deleted = '1' WHERE itemresponseid = ? AND version = ?

Answer 2

deleted的数据类型为long。因此，请从''

中删除SET deleted = '1'

Answer 3

上述问题通过以下方式解决：

UPDATE响应SET deleted = 1 WHERE itemresponseid =？和-1！=？
