我已经为我的参数计算了维度，其中等于 - 全部。但是，我也希望它 return null as 0

Question

IIF(

[Parameters].[Year] = 'All'

, 1=1


, [Parameters].[Year] = STR(YEAR([Date]))

)

tableau 如果参数 return 不匹配 return 0

Answer 1

试试这个，return 找到一个值时为 1，没有时为 0

INT([Parameters].[Year] = 'All' OR [Parameters].[Year] = STR(YEAR([Date])))

I have calculated dimension for my parameter where equals - All. however, I also want it to return null as 0
