将sql statemet转换为tableau计算字段

Question

Sql：

sum(case when invoicestatus in ('a','b','c') THEN  amount ELSE 0 END)

Tableau parameter : pivoicestatus = 'a','b','c'

Tableau calculated field:?

我想使用pinvoicestatus（参数）而不是对Tableau计算字段内的值进行硬编码

Answer 1

Tableau计算字段：

IF [pivoicestatus]='a'
THEN amount
ELSE IF [pivoicestatus]='b'
THEN amount
ELSE IF [pivoicestatus]='c'
THEN amount
ELSE 0
END
