What happens when you call FN dump dblog?
Edit 8/15/13: Beware – Jonathan just found out from a customer system that uses this extensively that every time fn_dump_dblog is called, it creates a new hidden SQLOS scheduler and up to three threads, which will not go away (and will not be reused) until a server restart. It’s a bug that the SQL team is going to fix now we’ve alerted them to it.
Do you need permission to use FN _ dblog?
The required permission to use the fn_dblog system table-valued function is sysadmin role membership. Importantly, this function is undocumented so it should not be used in application code, especially to update a table. Your comment indicates the function is used in a trigger.
How to grant system object permissions in SQL Server?

Where to find deleted rows in SQL Server?

What happens if I drop a table in SQL Server?
Step 2: As was the case with our first example, if you drop a table or you perform any transactions in your database, they will get logged in SQL Server Transaction Log which will be accessed by using the fn_dblog function. Run the below script to display entries which have been logged as a DROP statement.
How to restore fndblogtest _ log2.bak from disk?
FROM DISK = N’D:\\SQLskills\\FNDBLogTest_Full.bak’ FROM DISK = N’D:\\SQLskills\\FNDBLogTest_Log1.bak’ DISK = N’D:\\SQLskills\\FNDBLogTest_Log2.bak’ And the table is there again, right before the point it was dropped. You can see where I used the constructed LSN string in the final log restore.
What to do if log records dont exist?
You might even be able to look in the inactive portion of the log by using trace flag 2536, which instructs the log reader to ignore the log truncation point and dump all possible log records from the log. But what do you do if the pertinent log records just don’t exist in the log anymore?
