I knew of the function to return the login for the current connection, but I thought it was like GETDATE() where you just provide the parentheses because they're required. I guess I should take a closer look at some of those functions once in a while.

Glad it helped but give the credit to Randal's post, it's all there... :w00t:

I knew about fn_dblog but answered that you can't do it without third party because the question was asking for "whodunnit" which to the best of my knowledge you can't determine from that. Is the something in there that can be used to tie that back to a user?
Please check this out
select SUSER_SNAME([Transaction SID]), *
from fn_dblog(null,null)

Thanx 4 sharing the script, but if u have a common SQL login that is being used by an application accessed by many users, then it`s kind of useless unless u have other information like host name or IP address.

Thanks & Best Regards,

Well, that's a completely different story, I guess the log writes enough to redo a transaction when restored, so if it doesn't write that info (or maybe the function does not retrieve it), most probably is not required for the purpose.

You can check the available columns using this

SELECT TOP 1 *

INTO #fn_dblog

FROM fn_dblog(null,null)

EXECUTE tempdb..sp_help '#fn_dblog'

That is true. However keep in mind the original question is about dropping a table. I would hope your application doesn't make a habit of dropping tables. 😉

I certainly hope not. If so, be sure to find a deep hole for the developer. 😛
