我有下表：
+------+--------+-----------+------------------+-----------------+
| ID | Name | FATHER_ID | Generation Level | Last Generation |
+------+--------+-----------+------------------+-----------------+
| 001 | John | 003 | 5 | x |
| 002 | Tim | 004 | 3 | x |
| 003 | Max | 005 | 4 | |
| 004 | Jim | 006 | 2 | |
| 005 | Matt | 004 | 3 | |
| 006 | Philip | | 1 | |
| 007 | Tom | 005 | | |
| 008 | Brad | | 1 | |
| 009 | Peter | 008 | 2 | |
| 0010 | Bryan | 009 | 3 | x |
| 0011 | Jane | 009 | 3 | x |
+------+--------+-----------+------------------+-----------------+
每个人都链接到父亲ID，但ID 006和008却没有父亲，因为他们是第一代。
我想通过sql查询或过程按如下方式将最后一代的大子代与其祖先链接起来。

| John | Jim |
| John | Phillip |
