[Yasith Tharindu]

We need to find out all the participants of all the projects for last year of period. What could be the SQL or CLI query would be for find it.

participants means everybody who has don any kind of a activity on any issues.

With SQL, the simple approach is to

1. read changegroup for author, date and issue-id, that gives you a set of users who changed issues
2. read jiraaction for the same, which gives you all the comments
3. read jiraissue for creator and created date to get the people creating the issue

You'll then need to read cwd_user to match the author and creator to users, but that may vary depending on what user directories you are using.
