  • No need for the ActiveRecord flag. The MAX(*) row should always be the current record. Restoring to a previous version simply inserts said row into the table again. Commented Jul 10, 2012 at 14:19
  • I wasn't sure how to make the select work, but now that you're calling this out I'm thinking about it and have an idea, hmmmm Commented Jul 10, 2012 at 14:34
  • Usually MAX(column_name) selects the largest value in the table's column. To select the whole row, a simple select top 1 order by id descending will do. Commented Jul 11, 2012 at 7:46
  • Yeah, that works for a simple single record but my table was a collection of child records which would need to be selected at once but could have been modified individually. Just a little more complex. Commented Jul 11, 2012 at 12:05
