Given table A:
| id | value1 | value2 |
|---|---|---|
| 1 | 0.33 | 0.25 |
| 2 | 0.4 | 0.7 |
and table B:
| date | id | quantity |
|---|---|---|
| 01/08 | 1 | 0.25 |
| 01/08 | 2 | 0.45 |
| 02/08 | 1 | 1 |
| 04/08 | 2 | 0.7 |
I would like to create a table which joins A and B by id and sums all value1 and value2 for all dates like this:
| date | value1 | value2 |
|---|---|---|
| 01/08 | 0.25 * 0.33 + 0.4 * 0.45 | 0.25 * 0.25 + 0.45 * 0.7 |
| 02/08 | 0.33 | 0.25 |
| 03/08 | 0 | 0 |
| 04/08 | 0.7 * 0.4 | 0.7 * 0.7 |
How can I achieve this?
