Basically I would like to filter if there are more than one not null values in a row for certain variables. I searched the forums and could not find an answer any help or direction to resources would be greatly appreciated.
Would like to filter all rows that have more than one value for room type variable. but have it so it could scale to 20+ room variables as Trying to create unique conditional like: !isnull(Room) and !isnull(Room3) I don't think scales well?
Current example:
| ID | Room | Key | Room2 | Key2 | Room3 | Key3 |
| 1 | DWGS | 2 | null | null | null | null |
| 2 | AGSW | 1 | null | null | KLBF | null |
| 3 | null | null | OPDF | 3 | null | null |
Expected after filter:
| ID | Room | Key | Room2 | Key2 | Room3 | Key3 |
| 2 | AGSW | 1 | null | null | KLBF | null |
