SSRS 中的 MDX 参数

Question

大家好，希望有人能帮助我创建以下成员，这就是代码看起来如何硬编码。

WITH MEMBER [Measures].[CoinInRank] AS CASE 
WHEN [Measures].[Total Amount Bet] <= 5100  AND [Measures].[Total Amount Bet] > 0 THEN "Casual"
WHEN [Measures].[Total Amount Bet] > 5100 AND [Measures].[Total Amount Bet] <=  25000 THEN "Frequent"
WHEN [Measures].[Total Amount Bet] > 25000 THEN "Avid"
END MEMBER

现在我想传递数量范围，即 5100 和 25000 作为 SSRS 的参数，我已经尝试了以下方法，但没有成功。

WITH MEMBER [Measures].[CoinInRank] AS CASE 
WHEN [Measures].[Total Amount Bet] <= STRTOSET(@FrequentMinValue,CONSTRAINED)   AND [Measures].[Total Amount Bet] > 0 THEN "Casual"
WHEN [Measures].[Total Amount Bet] > STRTOSET(@FrequentMinValue,CONSTRAINED) AND [Measures].[Total Amount Bet] <=  STRTOSET(@FrequentMaxValue,CONSTRAINED) THEN "Frequent"
WHEN [Measures].[Total Amount Bet] >  STRTOSET(@FrequentMaxValue,CONSTRAINED)  THEN "Avid"
END MEMBER

如有任何建议，我们将不胜感激。

Answer 1

StrToSet 将字符串转换为集合。 Measures 是一个数值表达式，因此无法与集合进行比较。如果你去掉 StrToSet 会发生什么？

WITH MEMBER [Measures].[CoinInRank] AS CASE 
WHEN [Measures].[Total Amount Bet] <= @FrequentMinValue   AND [Measures].[Total Amount Bet] > 0 THEN "Casual"
WHEN [Measures].[Total Amount Bet] > @FrequentMinValue AND [Measures].[Total Amount Bet] <=  @FrequentMaxValue THEN "Frequent"
WHEN [Measures].[Total Amount Bet] >  @FrequentMaxValue THEN "Avid"
END MEMBER

Answer 2

您可能需要在此处重新检查语法。最后的 MEMBER 看起来不属于这里。

CASE 的语法是

WITH MEMBER [Measures].x AS 
CASE 
   WHEN 1>2 THEN 'false'
   WHEN 2>1 THEN 'true'
   ELSE 'none'
END

由于您从报告中提取值，因此该值将采用字符串格式。我不确定 MDX 引擎是否允许将数值与 string.So 进行比较是否更安全，您可能需要使用 StrToValue 函数将该文本值转换为数字。

您的最终查询应如下所示 -

WITH MEMBER [Measures].[CoinInRank] AS CASE 
WHEN [Measures].[Total Amount Bet] <= STRTOVALUE(@FrequentMinValue,CONSTRAINED)   
AND [Measures].[Total Amount Bet] > 0 
   THEN "Casual"
WHEN [Measures].[Total Amount Bet] > STRTOVALUE(@FrequentMinValue,CONSTRAINED) 
AND [Measures].[Total Amount Bet] <=  STRTOVALUE(@FrequentMaxValue,CONSTRAINED)
   THEN "Frequent"
WHEN [Measures].[Total Amount Bet] >  STRTOVALUE(@FrequentMaxValue,CONSTRAINED)  
   THEN "Avid"
END

希望对你有帮助。
