How to see a list of sub-tasks completed in a given sprint?

[Benjamin Pettus]

I am using a team project in Jira. My team uses a lot of sub-tasks, and often the parent task gets rolled over several sprints as sub-tasks are being completed. However, I still want to be able to track the items that are being completed in individuals sprints, and as the majority of these are subtasks I need to be able to query for a list of sub-tasks that were completed in a specific sprint (status changed from in progress to done).

This is what I have tried (2022-07-04) is standing in for the start date for the sprint that I am interested in)

project = "projectname" and issuetype = Subtask and resolution was EMPTY AFTER (2022-07-04) and resolution is not EMPTY

But it returns nothing even though I know there are sub-tasks completed in that data range. How can I do this?

Sub-tasks are not sprint items, they don't go into a sprint.  I mean, they do, but only because they are a part of their parent, they are not independent of their parent.  So you can't really say they are completed in any sprint, it's not relevant data.  You should be reporting on their parent

You'll have to come up with some complex reporting that can read their parent history for a sprint and combine that with all the dates you need to work with).  I can't work out a way to do it inside Jira.  

The best I can come up with is something that copies the sprint names down on to sub-tasks whenever you change the sprint name on a parent.  That would make the reporting easier (but no more correct - you shouldn't be trying to report on sub-tasks like this, nor should you have a case where "often the parent task gets rolled over several sprints" - you're supposed to be fixing your processes such that a story fits within a single sprint)
