获取相邻的列词？

Question

我想要像“if max(col1) then col2 end”这样的条件，在画面计算字段中，输出将为“e”。提前致谢

Answer 1

我已经按照这些步骤进行了尝试，它看起来很有效:)

# first find the max. Using fixed lod calculation to do it across the whole dataset. The 1 is the same value across all so its doing a group max, but the group is the full data
MaxCol1: {fixed 1: MAX(Col1)}

# pick out rows where max is found in Col1
Col1Match: Col1=[MaxCol1]

# find Col2 where there's a match and fill rest with NULL's
Col2Value: IF [Col1Match] then Col2 else NULL end

# This will be a bunch of NULL's and "e"
# Finally, do the same as in the first calculation to get the result
Output: {fixed 1 : max([Col2Value])}

您现在可以尝试将其中的一些步骤组合在一起，稍微清理一下 space。这够用了还是你的真实数据更复杂？

最好，强尼

Answer 2

简单使用

If [col1] = {max([col1])} then col2 end

将其放在视图中并隐藏空值，您将获得所需的值。
