=====GrandChildTicket=====

**Level:**   __Major__    


**Purpose:** Notify operations that is a grand child ticket is on the system.

**Scenario:** Grand child tickets prevent a user from moving a ticket to a new state. Issue occurs occasionally when automated system and a user parent a ticket at the exact same time.

**Resolution:** Run the "Grand Child Tickets" report which gives you a query to run to resolve the issue.

**Manual Action Steps:** Query to check for grand child tickets.
<del><code> SELECT
  pt.id AS child_id,
  pt.parent_id AS parent_id,
  gc.id AS  grand_child_id,
  gc.parent_id AS  grand_child_parent_id
FROM
  ticketer.ticket pt
JOIN ticketer.ticket gc ON
  gc.parent_id = pt.id
WHERE
  pt.parent_id IS NOT NULL;
</code>
  
From the query above take the child_id value and set the parent_id to null
<code>update ticketer.ticket set parent_id = NULL where id = <child_id>;</code></del>

Just execute the below query:
<code>
update ticketer.ticket set parent_id = NULL where id in (select * from (SELECT
  pt.id AS child_id
FROM
  ticketer.ticket pt
JOIN ticketer.ticket gc ON
  gc.parent_id = pt.id
WHERE
  pt.parent_id IS NOT NULL) a);
</code>

**Auto Clear:** Will clear when there are no grand child tickets on system.
