[Michael Angelo Timoteo]

My scenario is that I needed to have a JQL query wherein I needed to clear a custom field value called "Investor ATM" because it is confidential but retain the value on the ticket.

Is this possible?

JQL queries can only return issues. It can not clear values of custom fields.
