Thank you Ruslan.
Now I'm half way...
I had:
| name | surname | town | color |
| John | Smith | New York | Blue |
| John | Smith | New York | Red |
| Steve | Jobs | Rome | Blue |
| Steve | Jobs | Rome | Green |
| Carl | Mirren | London | Yellow |
I want:
| name | surname | town | red | green | blue | yellow |
| John | Smith | New York | 1 | | 1 | |
| Steve | Jobs | Rome | | 1 | 1 | |
| Carl | Mirren | London | | | | 1 |
I have now:
| name | surname | town | red | green | blue | yellow |
| John | Smith | New York | 1 | | | |
| John | Smith | New York | | | 1 | |
| Steve | Jobs | Rome | | 1 | | |
| Steve | Jobs | Rome | | | 1 | |
| Carl | Mirren | London | | | | 1 |
Now I'm trying to consolidate multiple rows into one.
Suggestions welcome.
Cheers,
Giacomo
