In Postgres, I have an existing table:
things
| thing_id | thing_name | destination_id |
|---|---|---|
| 10 | thing 10 | null |
| 15 | thing 15 | null |
For each row in that table, I want to add rows to two new related tables one of which has an auto-generated ID. I then want to update rows in the old table to point to related new rows.
Desired result:
things
| thing_id | thing_name | destination_id |
|---|---|---|
| 10 | thing 10 | 1 |
| 15 | thing 15 | 2 |
parent_destination
| destination_id |
|---|
| 1 |
| 2 |
child_destination
| destination_id | destination_name |
|---|---|
| 1 | [destination] thing 10 |
| 2 | [destination] thing 15 |
I have tried to do it here: https://www.db-fiddle.com/f/6iyvCT7BYXPHPi2N2HvNor/1but I can't work out how to return the correct data from result1.
