JQL for finding issues recently moved from Unassigned to Assigned ?

[Karla Russell]

I'm interesting in searching for all issues in a project that were Unassigned and are now Assigned, in say that last 24 hours.  So 24 hours ago they were Unassigned and now they are not.

Thanks for all help in advance.

The following JQL would return issues who's assignees have been changed for unassigned to someone else since the start of the day

assignee changed AFTER startOfDay() and assignee is not EMPTY

You're 3/4 of the way there! 

Anyway to know if they were UNASSIGNED before they were assigned?  This shows that the Assignee has changed, but not that the issues were Unassigned prior to that.

This is a lot more than I had, so thank you for that!!

Maybe this:

assignee changed FROM empty AFTER startOfDay() and assignee is not empty

[Karla Russell]

That returns nothing at all.  Looks good tho.  :)
