What is source table in which 'Bug to Epic Link' and 'Bug to Story Link ' information is stored

[nallu]

I would like to know the source Jira database tables where I can find information of the below:

1. Bug to Epic Link (I get the details of Epic Story Link from ISSUELINKTYPE table but need to know where to find information for Bug linked to Epic)
2. Bug to Story Link

Using the database for reporting on these is not a good way to do whatever you are doing - the database is not built for reporting or investigations.

You'll find the epic link for a story stored in customfield, and other links are in issuelink, but you'll not have much fund reading either of them.
