我遇到了MySQL问题。我最近需要重建我的计算机，因为我得到了病毒。重建的一切进展顺利，但我很难让MySQL表现自己。我的数据库的配置文件与之前的配置文件完全相同，但是在重新启动MySQL后，我遇到某些表消失的问题。
以下是错误日志中的一段我相信详细说明此问题：

我曾经发过一次这个问题，但似乎没有人完全理解我的问题。为了更容易理解该问题，请观看this video，向我展示创建测试模式和测试表，重新启动数据库，并观察它消失。我打开的文件夹是MySQL服务器的ProgramData文件夹。 作为旁注，当我将lower_case_table_names设置为1时，不会发生消失表格的这种奇怪行为。我希望能够在我的表名中使用大写字符，就像我过去一样。
答案 0 :(得分：1)
问题现在已经解决了一段时间，但直到今天我才忘记这个问题所以我会回来回答它。显然我的MySQL服务器安装在某种程度上已经损坏，重新安装服务器解决了这个问题。
