Question:
Normally, you can undo a sql command with rollback.

BEGIN TRY
  BEGIN TRANSACTION
  /* run all your SQL statements */
  COMMIT TRANSACTION
END TRY
BEGIN CATCH
  ROLLBACK TRANSACTION
END CATCH

My question now:
If ‘one’ did this

UPDATE TABLE_X SET FIELD_X = 'bla'
GO

in SSMS (notice the go at the end) and forgot to specify the WHERE clause,
is it possible (and how) to rollback the implicit transaction that SSMS executed this command in (statements with go at the end are implicitly executed in a transaction) ?

Note:
I didn’t do that, but a colleague of mine did a few days ago (without go).
I undid the damage he did (fortunately I made a backup 0.5 hours before he did that), but for the future, it would be good to know this, because this happened to me once, too.
