Access Err Function

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. ms access #error in query Access 2007 Many thanks student View Public Profile Find More Posts by student 10-26-2011, 11:48 PM #2 mcalex Newly Registered User Join Date: Jun 2009 Posts: 135 Thanks: 2 Thanked 10 Times in 8 Posts Re: 'iferror' equivalent in access I haven't come across iferror in excel - maybe it's a 2007/2010 thing. 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),

I need to know if the thing I am looking at is a number or text. If it's text I want a zero, if it is a number I want the number. I know that when I use FormatNumber([C107_62xx]![F40]) on a text line I get an error. I would assume when http://stackoverflow.com/questions/22670418/iif-iserror-function-still-returning-error I get an error, then my iif formula above would convert that to a zero and the world would rejoice. For some reason I am still getting a #error even with my iif statement. What am I doing wrong? I have also tried using the IsNumeric function but I still get #NUM! errors that come through. function ms-access ms-access-2010 share|improve this question edited Mar 26 '14 at 19:16 HansUp 79.1k114371 asked Mar 26 '14 at 18:49 Nigel 2041211 add a comment| 1 Answer 1 active oldest votes up vote 5 down vote accepted IsError does not do what you think it does. From the help topic, it "Returns a Boolean value indicating whether an expression is an error value." Not whether the expression triggers an error, but whether the expression is an error value. Sorry, that explanation was probably not clear enough, but I don't know how to do better. So I'll just suggest you consider this IsNumeric() expression for what you want here. IIf(IsNumeric([62xx]![F40]), FormatNumber([62xx]![F40]), 0) Here is that same expression in a query with the output below. SELECT [62xx].F40, IIf(IsNumeric([62xx]![F40]), FormatNumber([62xx]![F40]), 0) AS MTD FROM [62xx]; F40 MTD ----- ---- foo 0 1 1.00 2.345 2.35 bar 0 share|improve this answer edited Mar 26 '14 at 19:27 answered Mar 26 '14 at 19:15 HansUp 79.1k114371 I don't understand why IsError d
controls don't exist, you cannot sum them. In forms The problem does not arise in forms that display the new record. It does occur if http://allenbrowne.com/RecordCountError.html the form's Allow Additions property is Yes, or if the form is bound to a non-updatable query. To avoid the problem, test the RecordCount of the form's Recordset. In older https://www.techonthenet.com/access/queries/divide_by_zero.php versions of Access, that meant changing: =Sum([Amount]) to: =IIf([Form].[Recordset].[RecordCount] > 0, Sum([Amount]), 0) Access 2007 and later have a bug, so that expression fails. You need a function. Copy error function this function into a standard module, and save the module with a name such as Module1: Public Function FormHasData(frm As Form) As Boolean 'Purpose: Return True if the form has any records (other than new one). ' Return False for unbound forms, and forms with no records. 'Note: Avoids the bug in Access 2007 where text boxes cannot use: ' [Forms].[Form1].[Recordset].[RecordCount] On access if error Error Resume Next 'To handle unbound forms. FormHasData = (frm.Recordset.RecordCount <> 0&) End Function Now use this expression in the Control Source of the text box: =IIf(FormHasData([Form]), Sum([Amount]), 0) Notes Leave the [Form] part of the expression as it is (i.e. do not substitute the name of your form.) For Access 97 or earlier, use RecordsetClone instead of Recordset in the function. A form with no records still has display problems. The workaround may not display the zero, but it should suppress the #Error. In reports Use the HasData property property, specifically for this purpose. So, instead of: =Sum([Amount]) use: =IIf([Report].[HasData], Sum([Amount]), 0) If you have many calculated controls, you need to do this on each one. When Access discovers one calculated control that it cannot resolve, it gives up on calculating the others. Therefore one bad expression can cause other calculated controls to display #Error, even if those controls are bound to valid expressions.

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 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.
