Paul Berglund Is there a better way to build a territory hierarchy?
I'm starting at the 4th level from the bottom and trying to build a territory hiearchy. What I'm seeing is I need to query the child territories one group at a time by getting the territories where the ParentTerritoryId = the starting territory Id, and doing multiple subqueries for each level below.
4th level territory = select Id, Name from Territory where id = :id;
3rd level territories = select Id, Name from Territory where ParentTerritoryId = 4th level territory id;
Build a map of all the Ids - called 3rd level territory ids
2nd level territories = select Id, Name from Territory where ParentTerritoryId in :3rd level territory ids;
Build a map of all the Ids - called 2nd level territory ids
1st level territories = select Id, Name from Territory where ParentTerritoryId in :2nd level territory ids;
Is there a more efficient way of doing this?
