Purpose

Currently, Confluence does not allow you to view previous versions of an edited comment. The aim of this KB is to display the history of an edited comment.

Solution

This SQL query will display all versions of a comment, the user that wrote the comment, and when they commented on it. The results will also be sorted in chronological order (from the original version down to the latest, current version).

SELECT c.contentid, bc.body AS comment, umlm.username AS commenter, c.lastmoddate AS dateCommented
FROM BODYCONTENT bc
JOIN CONTENT c
ON bc.contentid=c.contentid 
JOIN user_mapping umc
ON c.creator=umc.user_key
JOIN user_mapping umlm
ON c.lastmodifier=umlm.user_key
WHERE c.contentid='<INSERT COMMENT ID>' OR c.prevver='<INSERT COMMENT ID>'
ORDER BY c.lastmoddate;

Ensure you enter the comment ID where specified as <INSERT COMMENT ID>.
