未能解析 CASE 语句。 Google 数据工作室

Question

尝试在 Google Data Studio 中添加 CASE 语句时出现错误。

Failed to parse Case Statement

我哪里错了？

CASE
  WHEN _count_featues_null value = 0 THEN COUNT_DISTINCT(dataset name )
END

Answer 1

尝试移动 COUNT_DISTINCT 函数（并检查 _count_featues_null 的拼写？）：

COUNT_DISTINCT(CASE
    WHEN _count_featues_null value = 0 THEN dataset name
  END )
