選擇多值以及參數中具有空值的NULL值

Question

所以這有點令人困惑。我已經有一個存儲過程。我有5至6個參數的報告。我希望它以這樣的方式運行報表，以便您可以在下拉列表中選擇多個值並保持其可選（不選擇任何值）。其他的事情是我的參數值也有NULL值，我用NA代替它。我嘗試在參數屬性中使用默認值來進行某些選擇，而對於某些選擇它不適用。我仍然是SSRS工作的中間人。任何幫助將不勝感激。 謝謝

Answer 1

我假設你已經創建了一個函數，並在存儲過程中使用該函數來使該存儲過程成爲多值選擇。

在你的函數中無論哪個變量具有varchar或任何字符串數據類型，它們的大小都會像varchar（max）那樣變成MAX，並且在參數的存儲過程中也做同樣的事情。

此問題背後的原因：當您提供數據類型爲varchar（255）時，它只會取值爲255個字符，如果您的值字符超過了該限制，則會截斷超過該限制的數據。而你正在讓他們多選，所以你可能需要將它們作爲varchar（max）。

還將存儲過程中的參數大小設置爲Max。

注意：Varchar（Max）只是一個例子。您可以爲函數和存儲過程中使用的任何字符串數據類型提供最大值。

讓我知道，如果它的工作原理..
