类似的 Grant Fritchey 有一个问题，他关闭了 SSMS 并丢失了他一直在处理的查询……在这里写博客： 哦 **********！
编辑
为了让答案更详细一点，Grant 上面引用的链接提供了一个查询，可以简单地转到实例上的缓存以提取您刚刚执行的查询（或至少尝试）：
格兰特博客的评论中提到的更多选项：
2005+，默认追踪救援。
默认跟踪在 20mb 处翻转，但 SQL 保留 5 个跟踪的历史记录。通过访问服务器，您可以从 MSSQL\Log 目录中检索 *.trc 文件。如果您无法访问服务器，以下将为您提供当前默认跟踪文件的名称：
例如，如果当前文件是 E:\MSSQL.1\MSSQL\LOG\log_200.trc，则以前的文件应该是 log_199.trc、log_198.trc 等。使用以下命令获取跟踪的内容：
您可能能够从缓存的查询计划中检索信息，检查 BOL 以获取有关 sys.dm_exec_query_stats 的信息，或者从连接到同一数据库的管理工作室运行它：
过滤输出
缩小结果。
如果数据库处于完全恢复模式，则可能有机会恢复一些数据并通过读取事务日志了解所做的事情。
不幸的是，默认情况下不支持此功能，但有一些方法可以做到这一点。
您可以尝试使用第三方工具，例如ApexSQL Log或SQL Log Rescue（免费但仅限 SQL 2000）。
另一种选择是尝试使用未记录的函数 DBCC LOG 或 fn_dblog。这更复杂，但它是免费的。
可以使用系统视图查看查询历史记录：
例如，使用以下查询：
可以使用以下脚本查看当前正在运行的查询：
此请求显示所有活动请求以及所有明确阻止活动请求的请求。
所有这些和其他有用的脚本都作为SRV数据库中的表示来实现，该数据库是免费分发的。例如，第一个脚本来自视图[inf].[vBigQuery]，第二个来自视图[inf].[vRequests]。
查询历史记录也有各种第三方解决方案。我使用Dbeaver 的Query Manager 和 SQL Tools的Query Execution History，它嵌入在SSMS中：
如果您的数据库设置为完全恢复模式，您可以调查您的事务日志备份。有关
fn_dump_dblog更多信息，请参阅。
