SQL Queries

The following SQL shows how to find the commit author count in specific repositories, eg. 'repo-1' and 'repo-2'.

SELECT
  count(distinct c.author_id)
FROM 
  commits c
  LEFT JOIN repo_commits rc ON c.sha = rc.commit_sha
  LEFT JOIN repos r ON r.id = rc.repo_id
WHERE
  -- please replace the repo ids with your own, or create a '$repo_id' variable in Grafana
  r.id in ('repo-1', 'repo-2')
  and message not like '%Merge%'
  and $__timeFilter(c.authored_date)
  -- the following condition will remove the month with incomplete data
  and c.authored_date >= DATE_ADD(DATE_ADD($__timeFrom(), INTERVAL -DAY($__timeFrom())+1 DAY), INTERVAL +1 MONTH)

How to improve?​

As a secondary indicator, this helps assess the labor cost of participating in coding.
