If you do something in Dabble that affects your data somehow, you can always use the undo function to reverse the change.

Undo is only available for the last change you made. If you make another change, you cannot go two steps back.

Anytime a change is made, Dabble will add a message above the view briefly summarizing the change. Next to the summary is a link to undo the change. Click the link and your data will be restored to the state it was in before you made the last change.

Since a single operation in Dabble can affect more than on entry at once, clicking undo will reverse everything that was changed by the last thing you did. If the last operation affected one entry, that change will be reversed. If the last operation affected all of your entries, all of the changes will be reversed.

When you undo an operation, Dabble will summarize what was undone (in the same place as other changes are shown). If, after undoing an operation, you realize that you wanted to do it after all, you can click Redo and the operation will be re-applied. (Or in otherwords, your undo is undone.)

If you cannot use Undo to reverse a catastrophic mistake because you have made a subsequent change, you should contact the Dabble DB support team at support@dabbledb.com to discuss reverting to an earlier backup copy of your application.
