我遇到了一个相当奇怪的场景，不知道有没有人看到它。直到今天早上，我安装了一个 sql developer version 3.xx 并且多年来一直正常工作......当我试图将 300K+ 记录的视图导出到一个 excel 文件时。然后我离开了 sql developer，但是当我回来时，我无法再启动应用程序。没有错误，但什么也没发生。我进入应用程序内的 sqldeveloper 文件夹并使用 cmd.com 启动应用程序，这是错误（虽然不确定我是否应该从命令提示符运行它）

有人知道发生了什么吗？我试图从 Oracle 站点删除并获取另一个 sqldeveloper 副本，但情况并没有改善。有什么我忽略的吗？我相信导出对应用程序做了一些事情，但我不够聪明，无法弄清楚是什么。非常感谢您的提示！

try running the batch file to start it

It's probably in the same folder as the sqldeveloper.exe. It may be a Java level mismatch in which case you will be warned and asked if you want to proceed, or you can install a compatible version.
