# 3018 Self-Referencing Triggers Not Executing Properly and Stop After One Recursion

I have a simple EDB table containg the self-refencing structure for a tree. When I delete a row that represents the middle of a branch, I want to make sure that all orphans along the remains of the branch are also deleted. My curent trigger deletes the immediate orphan but does not appear to fire again when this itself is deleted (i.e. it doesn't nest) so I am left with spurious entries in my table.

TRIGGER "after_delete"
BEGIN
 DECLARE Structures_stmnt STATEMENT;
 PREPARE Structures_stmnt FROM 'DELETE FROM Structures
WHERE Structures.parent_id <> 0 AND
Structures.parent_id NOT IN (SELECT item_id FROM Structures)';
 EXECUTE Structures_stmnt;
END
