Posso ottenere query eseguite utilizzando:
SELECT deqs.last_execution_time AS [Time]
,dest.TEXT AS [Query]
FROM sys.dm_exec_query_stats AS deqs
CROSS APPLY sys.dm_exec_sql_text(deqs.sql_handle) AS dest
ORDER BY deqs.last_execution_time DESC
ma sto anche cercando la username
colonna, che ha eseguito queste query.
