sql-server - SQLServer异常: The conversion from timestamp to TIMESTAMP is unsupported.

Question

最近进行了一些数据库更改，并且 hibernate 映射出现了一些困惑。

hibernate 映射:

<class name="Member" table="MEMBER">
   <property name="lastLoginDate" column="last_login_date" type="calendar"/>
   ...other fields
</class>

成员模型对象:

public class MemberBean{
    private Calendar lastLoginDate;
    ... rest of class
}

堆栈跟踪:

Answer 1

您是否使用 TIMESTAMP 数据类型而不是 DATETIME 创建表？ TIMESTAMP 是一种命名不当的类型，由 ROWVERSION 别名并用于并发性 - 与日期或时间关系不大。
