You use IIf to determine if another access #num error expression is true or false. If the expression is true, IIf returns one value; if it is false, IIf returns another. You specify the values IIf returns. See some examples Syntax IIf ( expr , truepart

, falsepart ) The IIf function syntax has these arguments: Argument Description expr Required. Expression you want to evaluate. truepart Required. Value or expression returned if expr is True. falsepart Required. Value or expression returned if expr is False. Remarks IIf always evaluates both truepart and falsepart, even though it returns only one of them. Because of this, you should watch for undesirable side effects. For example, if evaluating falsepart results in a

division by zero error, an error occurs even if expr is True. Examples Use IIf on a form or report Suppose you have a Customers table that contains a field named CountryRegion. In a form, you want to denote whether Italian is the first language of the contact. You can add a control and use IIf in its Control Source property, like so: =IIf([CountryRegion]="Italy", "Italian", "Some other language") When you open the form in Form view, the control displays "Italian" whenever the value for CountryRegion is Italy, and "Some other language" whenever CountryRegion is any other value. Use IIf in complex expressions You can use any expression as any part of an IIf statement. You can also "nest" IIf expressions, allowing you to evaluate a series of dependent expressions. To continue with the preceding example, you might want to test for several different CountryRegion values, and then display the appropriate language depending on which value exists: =IIf([CountryRegion]="Italy", "Italian", IIf([CountryRegion]="France", "French", IIf([CountryRegion]="Germany", "German", "Some other language"))) The text "Some other language" is the falsepart argument of the innermost IIf function. Since each nested IIf function is the falsepart argument of the IIf function that contains it, the text "Some other language" is only returned if all the expr arguments of all the IIf functions evaluate to False.

See solution in other versions of Access: Access 2007 Access 2003 Question: In Microsoft Access 2003/XP/2000/97, I'm trying to write a formula in a query as follows: [Price]/[Quantity] Most of the times this formula works, but in some cases the [Quantity] field is zero so when the formula divides https://www.techonthenet.com/access/queries/divide_by_zero.php zero by zero, the result comes up as #Error. Is there a way I can tell Access, if dividing by zero, the result is zero? Answer: You can use the iif function in your Access query to handle these cases. We'll demonstrate how to do this with the example below. In this example, we've used the iif function to return 0 if the [Quantity] is 0. Otherwise, it would return the value of [Price] divided by [Quantity]. This is achieved with the following formula: IIf([Quantity]=0,0,[Price]/[Quantity]) Now, your Access query should no longer return an error when a [Quantity] of 0 is encountered.

But a properly used Nz() function can turn if error an error message into an understandable and expected value. By Susan Harkins | in Microsoft Office, February 6, 2009, 2:14 AM PST RSS Comments Facebook Linkedin Twitter More Email Print Reddit Delicious Digg Pinterest Stumbleupon Google Plus Missing values can confuse users if handled incorrectly. For instance, a calculated control in a form or report has the potential to return #Error if a value is missing. That's going to leave your users scratching if error formula their heads and reaching for the phone to ask what's up. You can avoid their confusion (and your interruption) by using the Nz() function to force a value — usually 0. This function's syntax is simple: Nz(expression, replacementvalue) where expression is the field or value being evaluated and replacementvalue is the value or text you want to display, or pass, when there's no value. (You can learn more about Nz() in Help.) I've found that applying Nz() correctly can be a bit of a puzzle for some folks. The key is to wrap every field or value in an Nz() function, not the entire expression. For instance, the following expression has the potential to return #Error, despite the Nz() function: =Nz(Sum(Price * Quantity, 0)) The correct syntax follows: =Sum(Nz(Price, 0) * Nz(Quantity, 0)) Wrap each field within the expression to catch each missing value before the SUM() function tries to evaluate it. Of course, the best solution is to prevent missing values in the first place. To do so at the table level, set the field's Required property to Yes. However, doing so isn't always appropriate or practical. That's when the Nz() function comes in handy — as long as you apply it correctly.
