我正在使用 MySql hibernate 并尝试更新记录，它给我错误。
代码
Query query = session.createQuery("update UserDetails set userStatus=:userStatus where id =(select max(id) from UserDetails where department=:department)");
query.setParameter("userStatus", "ACTIVE");
query.setParameter("department",55);
int result=query.executeUpdate();

谁能帮我改正这个问题？
最佳答案
更新 UserDetails 设置 userStatus=:userStatus where department=:department
关于java.sql.SQLException : You can't specify target table 'user_details' for update in FROM clause 异常，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/27396000/
