SQL Server - INSERT后返回值(SQL Server - Return value after INSERT)
我试图在INSERT-statement之后获得一个键值。 示例:我有一个表的属性名称和id。 id是生成的值。
INSERT INTO table (name) VALUES('bob');
现在我想让id回到同一步。 这怎么做?
我们正在使用Microsoft SQL Server 2008。
I'm trying to get a the key-value back after an INSERT-statement. Example: I've got a table with the attributes name and id. id is a generated value.
INSERT INTO table (name) VALUES('bob');
Now I want to get the id back in the same step. How is this done?
We're using Microsoft SQL Server 2008.

@beerbajay是正确的,@ Transaction将需要在你的bean上创建一个动态代理来应用事务逻辑,如果你的服务有一个接口,可以创建它,因为在你的情况下,它不会是一个替代指示Spring创建基于类的代理,方法如下:你缺少的是hibernate-entitymanager只包含包装hibernate核心的包装器,将它暴露为JPA实体管理器。 因此,如果您只是添加了您将无法获得实际的hibernate类,因此找不到您的类。 如果你看一下hibernate主页上组件如何结合在一起的图片,你会看到实体管理器建立在hibernate核心和hibernate注释之上。 您需要为这两者以及所有依赖项添加所需的jar。 这些文档描述了hibernate发行版中jar的各种文件夹,以及你需要哪些类型的jar用于什么样的用法。 What ...
