(SSRS) IIF 聲明 - 空白數據

Question

我不確定為什么，但我的 IIF 聲明似乎不想工作。

=IIF(IsNothing(Fields!Calculated_Address.Value),Fields!Calculated_Dummy.Value, Fields!Calculated_Address.Value)

數據示例

有可用數據。

Answer 1

用以下內容替換您的表達式

=IIF(IsNothing(Fields!Calculated_Address.Value) OR Trim(Fields!Calculated_Address.Value)="",Fields!Calculated_Dummy.Value, Fields!Calculated_Address.Value)

采樣數據集

select 'address1' as address, 'address has value' as dummy
UNION ALL
select '' as address, 'address is empty string' as dummy
UNION ALL
select null as address, 'address is null' as dummy
UNION ALL
select '   ' as address, 'address contains spaces' as dummy

Answer 2

我的查詢是通過一個程序創建的，但這里是簡單的。

查詢返回的數據

Answer 3

我想向大家道歉。

我在 RDL 文件中的查詢中錯過了Calculated_Dummy 。

=IIF(IsNothing(Fields!Calculated_Address.Value) OR Trim(Fields!Calculated_Address.Value)="",Fields!Calculated_Dummy.Value, Fields!Calculated_Address.Value)

工作完美。 謝謝你：）
