iif-function

the question is simple, there is a functional equivalent of the famous iif in java? For example: IIf (vData = "S", True, False) Thanks in advance. vData.equals("S") ? true : false or in this particular case obviously one could just write vData.equals("S") Yeah, the ternary op ? : vData.equals("S") ? true : false The main difference between the Java ternary operator and IIf is that IIf evaluates both the returned value and the unreturned value, while the ternary operator short-circuits and evaluates only the value returned. If there are side-effects to the evaluation, the two are not equivalent

I want my textbox to have an action ONLY if the condition is true, otherwise no action. This is what I have as my current action expression for going to another report: =IIf(Fields!MyTextbox.Value = "0", "Report2","") This does not produce my desired result. It gives the textbox an action regardless of the condition result. Is there a 'No Action' or 'Cancel Action' value? The null keyword in VB is Nothing : =IIf(Fields!MyTextbox.Value = "0", "Report2", Nothing) 来源： https://stackoverflow.com/questions/2463022/conditional-action-in-ssrs

I am using the following expression to work out a percentage: =Fields!Days.Value/Sum(Fields!Days.Value, "Date_month_name") Days.Value is showing as 0 however in a few of my results instead of reading 0% in my percentage column it is actually reading NaN (Not a Number). Does anyone know the exact expression forumla i need and where I should paste it in my current expression to say "Where NaN is showing, put a '0' instead?" (See image) general exception How about =IIF(Fields!Days.Value > 0,Fields!Days.Value/Sum(Fields!Days.Value, "Date_month_name"),0) I didn't have luck with the above answers.

Is there a IIf equivalent in C# ? Or similar shortcut? C# has the ? ternary operator, like other C-style languages. However, this is not perfectly equivalent to IIf() ; there are two important differences. To explain the first difference, the false-part argument for this IIf() call causes a DivideByZeroException , even though the boolean argument is True . IIf(true, 1, 1/0) IIf() is just a function, and like all functions all the arguments must be evaluated before the call is made. Put another way, IIf() does not short circuit in the traditional sense. On the other hand, this ternary

I am trying to evaluate a Price per Kilo ($/Kg) based on sales of a product. This works fine if the product was acutally sold during the period specified. However if the product is not sold the Kg (the denominator) ends up being 0 (zero) and an error results. - Divide by Zero error. I tried this =iif(KgSold=0,0,Revenue/KgSold) It appears that the iif function is calculating both the true and false results. How do I get around this. Should I be using the switch function instead? =switch(KgSold=0,0 KgSold<>0,Revenue/KgSold) You're right, it doesn't short circuit. That sucks. You'll have to do

In Visual Basic, is there a performance difference when using the IIf function instead of the If statement? Konrad Rudolph VB has the following If statement which the question refers to, I think: ' Usage 1 Dim result = If(a > 5, "World", "Hello") ' Usage 2 Dim foo = If(result, "Alternative") The first is basically C#'s ternary conditional operator and the second is its coalesce operator (return result unless it’s Nothing , in which case return "Alternative" ). If has thus replaced IIf and the latter is obsolete. Like in C#, VB's conditional If operator short-circuits, so you can now safely
