Community ChampionBLANK() in DAX
Hello,
I need to feed this logic into a measure.
| A | B | C | Is Exclude |
| blank | blank | blank | yes |
| blank | blank | 0 | yes |
| blank | 0 | blank | yes |
| blank | 0 | 0 | yes |
| 0 | blank | blank | yes |
| 0 | blank | 0 | yes |
| 0 | 0 | blank | yes |
| 0 | 0 | 0 | yes |
E.g. if I feed the above in a measure it would look like below.
Exclude1 := SWITCH(TRUE(),
[A]=BLANK()&&[B]=BLANK()&&[C]=BLANK(),"Exclude",
[A]=BLANK()&&[B]=BLANK()&&[C]=0,"Exclude",
..............................................
..............................................
[A]=0&&[B]=0&&[C]=0,"Exclude",
"Include")
Is it safe to assume that the measure below will produce exactly the same result as the one above
Exclude2 := SWITCH(TRUE(),
[A]=BLANK()&&[B]=BLANK()&&[C]=BLANK(),"Exclude",
"Include")
I once read in one of Zubair's post Zubair_Muhammad that DAX treats BLANK() as zero. If that is the case, can Exclude1 be optimized as Exclude2?
Thank you in advance.
smpa01 , March 2020 release support coalesce , you can do like
Switch(True()
coalesce([A],0) =0 && coalesce([B],0)=0 && coalesce([C],0) =0 , "Exclude",
"Include")
