If you need to  change the author of a Jira comment, the only way possible is to modify the jiraaction table in the database where the comments are stored. 


Applicable to all versions of Jire Core and Software 7.x/8.x and Jira Service Management 3.x and 4x.


 Please test these steps in your staging environment before performing the changes in production 

There are five steps needed to change the comment authors:

  1. Shutdown Jira
  2. Identifying the issueid of the issue that needs to be changed
  3. Identifying the ID of both users
  4. Updating the jiraaction table and changing the author
  5. Start Jira

We will work through the following example where we want to change the comment author from "clevine" to "thor".

The first query is simply to get the issue id:

select id from jiraissue I join project P on = I.project where P.pkey = 'GOT' and I.issuenum = 1;



Next, we need to get the ID of both users, we can query the cwd_user table for the two users with a similar query:

select AU.* from cwd_user CU join app_user AU on AU.lower_user_name = CU.lower_user_name where user_name in ('clevine','thor');



With this, we can then modify the jiraaction table. 

The author format in the jiraaction table is the user_key, with an example being JiraUSER10000.

 Our next would then be to change the author from clevine to thor with the following query:

update jiraaction set author = 'JiraUSER10100' where author = 'JiraUSER10000' and actiontype = 'comment' and issueid = 10000;

Once this query has been run, please start Jira and confirm the expected changes are present:
