I should mention, though, that the J2EE 1.4 specification states that you must be able to run 1.2 and 1.3 applications without change.
不过,值得一提的是,J2EE 1.4规范声明能够在不进行更改的情况下运行1.2和1.3版本的应用程序。
Note: Did I mention that all those names you put after constraint must be unique across your database?
注:我是否曾提到过放在constraint之后的所有那些名称在整个数据库中必须是惟一的?
