iif

问题 So, what is the purpose of the iif in vb? I know what it does, but I can't uderstand what is it for? Update: I know what it does. But "if(,,)" does the same. The only difference is that "Iif" will evaluate both expressions. So what is the purpose of doing this? Thank you! 回答1: It allows for a concise boolean logic expression which produces a value Dim value = Iif(someTest, trueValue, falseValue) Without the Iif or If operator this has to be expanded into a more combursome set of statements

问题 I have an SSRS report where I'm supposed to conditionally format a column red/green depending on if an expression is +/- 5% (less is good, so less is green). I also need to have the entire report have alternating row highlighting. I can get these to function correctly until I throw in some NULL handling. =Switch ( IsNothing(Sum(Fields!August2015.Value)),IIf(RowNumber(Nothing) Mod 2 = 0, "#d9d9d9", "Transparent"), (Fields!August2015.Value-Fields!CorporateAvg.Value)/Fields!CorporateAvg.Value >=

问题 I'm brand new to SSRS and could use some help: is it possible to nest a lookup expression inside an iif statement? I have a web form with checkboxes and would like to change the answer text from "True" and "False" to "Agree" and "Disagree", but because I'm using a lookup expression to get the responses, I can't use a simple iif statement. When I try to use two Expressions, I get an error message. Here are my expressions: =iif(ReportItems!Textbox70.Value = true, "Agree", "Do not agree")

问题 How do I create an a statement with an inline If (IIf, see also: Immediate if or ternary If) in PowerShell? If you also think that this should be a native PowerShell function, please vote this up: https://connect.microsoft.com/PowerShell/feedback/details/1497806/iif-statement-if-shorthand Update (7 October 2019) The Microsoft Connect is retired, but the good news is that support for a ternary operator in PowerShell (Core) language appears to be on it's way... 回答1: You can use the PowerShell’s

问题 At the following MDX code I want to get the aggregate of measure only for members that are in the specified last time (like in example 01/06/2015), else I don't want them . I tried existing and exists but without any luck. I believe i have to use the IIF function like: IIF DAYTIME, MEASURE D NOT NULL THEN AGGREGATE.... (if for the specific month, measure D is bigger than 0 then SUM measure D for the specific time range) ELSE NULL. (Else not print it on output) And then filter E.members where

问题 This is a simple question I hope. I learned about IIf today and want to implement it in some cases to save a few lines. IIF(isnumeric(inputs), resume next, call notnum) This is in red meaning there is a syntax error, how fix this? I have scanned MSDN article on this so I am not being lazy here. 回答1: That's not how the IIf function works. It's a function , not a statement : you use its return value like you would with any other function - using it for control flow is a bad idea. At a glance,

问题 I have the following error which I can't understand from my expression. =IIF(IsNothing(Fields!month.Value),"6mr",LEFT(Format(DateValue(MonthName(Right(Fields!month.Value, 2)) + "," + Left(Fields!month.Value,4)), "Y"),3) + " '" + RIGHT(Format(DateValue(MonthName(Right(Fields!month.Value, 2)) + "," + Left(Fields!month.Value,4)), "Y"),2)) This works perfectly without the IsNothing element. I have tested the IsNothing element and that works in the following case: =IIF(IsNothing(Fields!month.Value

问题 I have a task to get some code which is working correctly on SQL Server 2012 to work on SQL Server 2008 R2 as well. I got this error: Additional information: Incorrect syntax near '<' When I try to run my code I found out that something is wrong in this line of my SQL code ALTER TABLE [dbo].[WorkTimeEntries] ADD [TimeFinishedForRuntime] AS ISNULL([TimeFinished], IIF ([TimeStarted] < SYSUTCDATETIME(), [dbo].[udf_GetCurrentDateTimeOffsetInTimeZone](DATENAME(TZOFFSET, [TimeStarted])),

问题 This is my statement: iif(sum(Fields!myfield1.Value) = 0, 0, sum(Fields!myField2.Value)/sum(Fields!myField1.Value)) Any suggestions? 回答1: Likely it is evaluating as True. As mentioned in other comments, you'll get an error anyway because Iif() evaluates all parameter expressions regardless of the result of the test. The error can be avoided by adding another Iif() in the divisor. iif( sum(Fields!myfield1.Value) = 0, 0, sum(Fields!myField2.Value) / iif( sum(Fields!myfield1.Value) = 0, 1, sum

问题 I need to incorporate and iif statment in my expression. What I want to do is say if a field value = 0 then Fields!example1.value/Fields!example2.value else Fields!example1.value/Fields!example3.value. I hope that is clear in what I am trying to accomplish. 回答1: You have to validate twice in order to keep your report safe of division by zero erros. Try this: =iif( Fields!Field2.Value=0, iif(Fields!Field3.Value=0 ,0 ,Fields!Field1.Value/iif(Fields!Field3.Value=0,1,Fields!Field3.Value)), Fields
