Hello,
I need to get the values from D which are not assigned to a field in S:
S | A | D |
1 | x | x1 |
1 | x | x2 |
1 | b | b3 |
2 | b | b4 |
2 | x | x5 |
| x | x6 |
| x | x7 |
Example:
- No S selected. Result --> x6, x7 -Done: if( isnull(S),D)
-S=1 selected. Result -->b4,x5,x6,x7 - ?
-S=2 selected. Result --> x1,x2,b3,x6,x7 - ?
