Getting those email addresses that belong to more than 1 users in JIRA

Hi Everyone,

is there a Jelly, Groovy script or SQL code that return the email addresses that belong to more than 1 users? We have more than 10000+ users in our JIRA instance and many cases we create users several times by different usernames and same email addresses. We want to cleanup this mess in our instance.

Could you please give a hint?

 

Thanks,

Rumi

Hi, you can try this SQL code in your database:

 

SELECT email_address, count(*) FROM "cwd_user" group by email_address having count(*) > 1

 

This SQL will return all duplicated emails.

 

I'm going to improve this code to return ID too.

 

Or this one:

SELECT email_address,user_name FROM "cwd_user" WHERE (email_address) IN (SELECT email_address FROM "cwd_user" GROUP BY email_address HAVING COUNT(*) > 1)

 

I think this is more reliable

does my answer helps?
