所以这有点令人困惑。我已经有了一个存储过程。我有报告，其中有5到6个参数。我希望它以这样一种方式运行报告：您应该能够在下拉列表中选择多个值并保持可选（不选择任何值）。另一件事是我的参数值也有NULL值，我已用NA替换它。我尝试在参数属性中使用默认值进行某些选择，但是对于某些选择它没有。我仍然是SSRS的中间人。任何帮助将不胜感激。 谢谢

我假设您已经创建了一个函数并在存储过程中使用该函数来使该存储过程成为多值选择。
在您的函数中，无论哪个变量具有varchar或任何字符串数据类型，都将其大小设置为MAX，如varchar（max），并在参数的存储过程中执行相同的操作。
这个原因背后的原因：当您提供数据类型为varchar（255）时，它将只取一个255字符的值，如果您的值字符超过该限制，那么它将截断超过该限制的数据。你正在使它们多选，所以你可能需要将它们作为varchar（max）。
在参数的存储过程中也将大小设置为Max。
注意：Varchar（Max）只是一个例子。您可以为函数和存储过程中使用的任何字符串数据类型提供max。
让我知道它是否有效..
