Access If Error Then 0
Registered User Join Date: Oct 2011 Posts: 45 Thanks: 3 Thanked 6 Times in ms access #error in query 6 Posts 'iferror' equivalent in access I have a query producing a large number of records, calculating number manufactured and number sold of access #num error each product in inventory. This is based on number of boxes/products/sheets. Some items have not been moved in the month so have no record to pull through to this query so the result produces an #Error result

as opposed to a blank or a negative. In Excel, I'd normally use an IFERROR formula to deal with this, but cannot find a reasonable equivalent of this in Access. The format would be something along the lines of '=iferror(x*y,"")' I have 'x*y', no worries Any help on a generic formula equivalent would be greatly appreciated, preferably in its most simple form - I know there are several noobs like me out there looking for an

easy way around this omission.

In any event, they managed to get by with this omission up til 2003, by using an if() wrapped around an IsErr(). The only difference in Access is you wrap the if() around an IsError(), so: If(IsError(x*y),

But a properly used Nz() function can turn an error http://www.access-programmers.co.uk/forums/showthread.php?t=217455 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 their heads and http://www.techrepublic.com/blog/microsoft-office/use-nz-to-replace-an-error-message-in-access/ 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.

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 if error in 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.

Using IsError() in query expression P: n/a Tooled I am writing a vb.net app that uses ms-access as its database. I need to allow users to create their own custom sql expressions that will eventually be used in their reports. After they have created their expression, I will store the expression in a db table (as a string). Now when they go to create a report, they can choose one or more expressions (that they have previously created) that will be used to gather numerical data which will be displayed in their graphical report. The problem here is that the expression they create may create an error at runtime (i.e. divide by zero). To avoid any runtime #Error's, I attempted to wrap their defined expression with IIF() and IsError(). For example: If the user defined the expression as: "SELECT A.foo / B.bar" I tweeked the string to read: "SELECT IIF(IsError(A.foo / B.bar,NULL,A.foo / B.bar))" If/when I run the tweeked version of the expression and "B.bar" = 0, I would receive an #Error value, otherwise, the expression fired off w/out problems. My question, finally, is how can I trap for "any" error that the expression may cause? And, if an error does occur, how do I assign that individual record a value of NULL? In other words, I don't want the entire record set to fail due to one error prone record. Keep in mind that I'm trying to avoid hard coding a condition as in: IIF(B.bar = 0,NULL,B.bar) - for me to use this method would mean that I'd have to write an expression parser - which, to be honest, is a little out of my league (not to mention, I'm too lazy).
