mysql - Mysqlストアドプロシージャ:指定された親のすべての子ツリーのバグを数える

Question

私はこの問題で立ち往生しています。

2 つのテーブルのバグとプロファイルがあります

profiles table

id name parentid
1  A     0
2  B     1
3  C     1
4  D     2
5  E     2
6  F     3
7  G     5

等々

バグ

id  assigned_to
1    1
2    3
4    7

等々

assigned_to は、プロファイル テーブルの ID の外部キーです

単一のストアド プロシージャでは、特定の親の子を含むテーブルと、それらの子の子ツリーのバグの数を表示する必要があります

親の名前を渡すと、直接の子のテーブルを作成できるようになりましたが、バグの数は子のみであり、その子のツリーではありません

助けてください

ここに私のコードがあります
