GetAllDocumentsByKey with an empty string as first parameter returns an empty collection.

If you want to get all documents with an empty value in view's first sorted column then change the formula of your first sorted column to

@If(YourFieldName = ""; " "; YourFieldName)

It has a space instead of an empty string now.

Set tobeDeleted=timeVw.Getalldocumentsbykey(" ", true)

returns all those documents then.
