Dear,
I have a table that look like the following:
| id | Item |
|---|---|
| 1 | A |
| 2 | B |
| 3 | C |
| 4 | K |
| 4 | C |
| 4 | B |
| 5 | A |
and I would like to have a query that show this new view:
| Item 1 | Item 2 |
|---|---|
| K | C |
| K | B |
| C | K |
| C | B |
| B | K |
| B | C |
which is displaying Only the relation between items that has more than one record for the same id in the first table.
best regards,
Murhaf Khaled
