带有语法错误的 Reporting Services 查询

Question

我有这个查询，我将一个参数的值传递给另一个参数。

第一个参数被命名：

@OrdersMonth

并且对最终用户可见，第二个名为：

@OrdersPrevMonth

被隐藏并通过以下查询从可见参数中获取值：

="[Orders].[PrevMonth].&["
& switch(
Parameters!OrdersMonth.Value, True, "All",
Parameters!OrdersMonth.Value Like "*All*","All",
Parameters!OrdersMonth.Value Like "*January*","January",
Parameters!OrdersMonth.Value Like "*February*","February",
Parameters!OrdersMonth.Value Like "*March*","March",
Parameters!OrdersMonth.Value Like "*April*","April",
Parameters!OrdersMonth.Value Like "*May*","May",
Parameters!OrdersMonth.Value Like "*June*","June",
Parameters!OrdersMonth.Value Like "*July*","July",
Parameters!OrdersMonth.Value Like "*August*","August",
Parameters!OrdersMonth.Value Like "*September*","September",
Parameters!OrdersMonth.Value Like "*October*","October",
Parameters!OrdersMonth.Value Like "*November*","November",
Parameters!OrdersMonth.Value Like "*December*","December")
& switch(
Parameters!OrdersMonth.Value, True, "",
Parameters!OrdersMonth.Value Like "*All*","",
Parameters!OrdersMonth.Value Like "*2013*"," 2013",
Parameters!OrdersMonth.Value Like "*2014*"," 2014")
&"]"

第一个参数的值如下：

[Orders].[Month].&[All]   
[Orders].[Month].&[January 2014]
[Orders].[Month].&[February 2014]

2013 年和 2014 年以此类推

所以我的意图是第二个参数是哪些维度：

[Orders].[PrevMonth].&[]

是在第一次更改前一个查询时获得相同的最终值（2014 年 1 月），但我的最终输出如下：

报告处理过程中发生错误。 (rsProcessingAborted)
查询参数“OrdenesMesFin”的值表达式包含错误：表达式引用了报表参数集合中不存在的参数。 (rsRuntimeErrorInExpression)

为什么会这样？

这看起来很眼熟……喂！

您的 Switch 语法在这两种情况下都不正确。将, True, "All"移到Switch参数列表的末尾，然后删除开头的Parameters!OrdersMonth.Value,
