Dataset:It includes flags in column ; flags' value can be 0,1, or null.
AlteryxTool:IN-DB Filter
Description:flag = 1
In the above case, the result is...
TRUE side has rows which have flag=1,
FLASE side has rows which have flag=0.
SO, there're no rows which have flag=null...
Is this a bug in Alteryx? or Specification??
