无法从安卓设备连接到Firebird服务器

Question

我正在使用Jaybird连接Firebird sql，我的应用程序以前可以正常连接。但是今天我无法连接。

我唯一做的更改是在Android Studio中执行检查器的自动修正。我不知道是什么原因导致了这个错误。

错误335544472 = 您的用户名和密码未定义。请向您的数据库管理员请求设置Firebird登录。 （这也可能表示您没有正确安装驱动程序，因为驱动程序中包含了错误代码到错误消息的映射） - Mark Rotteveel

Answer 1

如我昨天的评论所暗示的，这个错误说明您的用户名和/或密码是不正确的（错误代码335544472 = 您的用户名和密码未定义。请询问您的数据库管理员设置火鸟登录。）。我无法理解这可能是由格式/布局更改引起的。

你的用户名或密码已经被更改（在你的代码或服务器上），或者你正在连接到一个不同于你期望的Firebird服务器。

如果您尝试连接到一个没有设置对旧认证支持的Firebird 3（beta/RC）服务器，也会发生此错误。另请参见Jaybird and Firebird 3.0 Beta 2.

您还可以检查安装Jaybird for android，因为它似乎缺少错误消息属性文件。
