Lets assume I have this sample data:
| Name | ID | PARENT_ID |
-----------------------------
| a1 | 1 | null |
| b2 | 2 | null |
| c3 | 3 | null |
| a1.d4 | 4 | 1 |
| a1.e5 | 5 | 1 |
| a1.d4.f6 | 6 | 4 |
| a1.d4.g7 | 7 | 4 |
| a1.e5.h8 | 8 | 5 |
| a2.i9 | 9 | 2 |
| a2.i9.j10| 10 | 9 |
I would like to select all records start from accountId = 1, so the expected result would be:
| Name | ID | PARENT_NAME | PARENT_ID |
-------------------------------------------
| a1 | 1 | null | null |
| a1.d4 | 4 | a1 | 1 |
| a1.e5 | 5 | a1 | 1 |
| a1.d4.f6 | 6 | a1.d4 | 4 |
| a1.d4.g7 | 7 | a1.d4 | 4 |
| a1.e5.h8 | 8 | a1.e5 | 5 |
I am currently able to make the recursive select, but then I can't access the data from the parent reference, hence I can't return parent_name. The code I'm using is (adapted to the simplistic example):
SELECT id, parent_id, name
FROM tbl
START WITH id = 1
CONNECT BY PRIOR id = parent_id
What SQL should I be using to the mentioned above retrieval?
Additional key words for future seekers: SQL to select hierarchical data represented by parent keys in same table
