How Can I Recover and View My SQL Server Management Studio Query History?

Accessing Your SQL Server Management Studio (SSMS) Query History

Unlike many applications, SSMS doesn't maintain a persistent query history log. However, if the SQL Server instance hasn't been restarted, you can attempt to recover recent queries from the plan cache using the following query:

SELECT t.[text]
FROM sys.dm_exec_cached_plans AS p
CROSS APPLY sys.dm_exec_sql_text(p.plan_handle) AS t
WHERE t.[text] LIKE N'%something unique about your query%';

Remember to replace '%something unique about your query%' with a distinctive portion of the query you're trying to find.

Recovering After a Crash:

If SSMS crashed, you might find backups of your query history in this directory:

<code>C:\Users\<your_username>\Documents\SQL Server Management Studio\Backup Files\</your_username></code>

Preventing Future Loss:

To prevent future loss of your query history, consider these options:

• SSMS Tools Pack: This add-in (note: not free for all SQL Server versions) provides enhanced features, including query history management.
• Server-Side Tracing: Configure server-side tracing, filtering by your login or hostname, to capture query execution details.

Optimizing the Recovery Query:

For more efficient retrieval, especially in busy environments, consider this improved query which joins with sys.dm_exec_query_stats and orders by the last execution time:

SELECT t.[text], s.last_execution_time
FROM sys.dm_exec_cached_plans AS p
INNER JOIN sys.dm_exec_query_stats AS s
   ON p.plan_handle = s.plan_handle
CROSS APPLY sys.dm_exec_sql_text(p.plan_handle) AS t
WHERE t.[text] LIKE N'%something unique about your query%'
ORDER BY s.last_execution_time DESC;
```  This will return results ordered from most recently executed to least recently executed.
