Log Sql Server Transactions (Queries + username)

I need to see which user has made what query with a lookback of ~90(?) days. I have activated change tracking on the database with 90 days. I have found several solutions: SELECT deqs.*, dest.*, 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 But this query doesn't give me any information about the user who made the query. Then I got this query SELECT * FROM FN_TRACE_GETTABLE('E:\MSSQLServer\MSSQL12.DBNAME\MSSQL\Log\log_29.trc', default) WHERE TextData IS NOT NULL ORDER BY TransactionID DESC This give me the username but no statements about DELETE/UPDATE etc. I read about the SQL Profiler but I can't copy/read the _log.mdf-files because it is always in use. I need a tip what s the right way to do this.. :/
