Access Form Count Records In Table
up it shows #Error Anyone have any ideas how to overcome this. I have also tried =Count([tbl_Players]) Again that came up with #Error Thanks in advance. Mar 6 '09 #1 Post Reply Share this Question 6 Replies Expert Mod 2.5K+ P: 2,543 Stewart Ross The #Error message usually arises when you supply a field name that is not recognised as part of the underlying recordset, or when you have accidentally set the name of the unbound control concerned to be the same as an access count records in subform existing field (which would prevent Access from knowing which one to apply). Simplest answer, since Count does not need a field name, is to set the control source to be =Count(*) This will give you a count of the number of records in the recordset underlying your form. However, if you are using an unbound form (one that is not bound to a query or table) you have nothing to count. If this is the case you can perform a lookup of the count of the number of records in a table by using the DCount function: =DCount("*", "tbl_Players") -Stewart Mar 6 '09 #2 reply P: 15 Lensmeister Hi Stewart, Thanks for that. It is a unbound form. Can I confirm that if I wanted to cont the number of "W" in the table Matches in the column/Field R the formula would be =Dcount("W","Matches","V") ? ? ? ? ? Lensmeister. Mar 8 '09 #3 reply Expert Mod 2.5K+ P: 2,543 Stewart Ross Not quite; DCount (like the Count function) counts the number of rows in the dataset. To count rows that have 'W's (or any other value) in them you need to restrict the rows being counted to be only those where the field or fields concerned have that value. DCount can do this, using its WHERE clause (which is like an SQL WHERE clause without the word WHERE. For a string comparison use the first form of the DCount below, for a number use the second: Expand|Select|Wrap|Line Numbers DCount("[nameofsomefield]","[yourtablename]","[fieldyouwanttocompare]='W*'")' United States Australia United Kingdom Japan Newsletters Forums Resource Library Tech Pro Free Trial Membership Membership My Profile People Subscriptions My stuff Preferences Send a message Log Out TechRepublic Search ms access vba count records in form GO Topics: CXO Cloud Big Data Security Innovation Software Data Centers Networking Startups count records in access report Tech & Work All Topics Sections: Photos Videos All Writers Newsletters Forums Resource Library Tech Pro Free Trial Editions: record count in access US United States Australia United Kingdom Japan Membership Membership My Profile People Subscriptions My stuff Preferences Send a message Log Out Microsoft A quick method for counting Access records in a form https://bytes.com/topic/access/answers/865666-form-textbox-count-function-problem When you need to count records in an Access form, try the Count() function. By Susan Harkins | in Microsoft Office, September 3, 2009, 5:00 PM PST RSS Comments Facebook Linkedin Twitter More Email Print Reddit Delicious Digg Pinterest Stumbleupon Google Plus There are several ways to count the records in a form's recordset. In fact, Access forms display the record count by default. For http://www.techrepublic.com/blog/microsoft-office/a-quick-method-for-counting-access-records-in-a-form/ many, this built-in feature is more than adequate. However, some people choose to inhibit the Navigation buttons, which display the record count. If users need to see the number of records populating a form and the form doesn't display the Navigation buttons, drop in a Count() function to display the record count as follows: With the form in Design view, insert a text box control. Enter the expression in the form =Count(primarykey) as the control's Control Source property. The Count() function takes just one argument, and in this case, that's the name of the field that contains a unique value for each record — usually the primary key. With the form in Form view, the expression returns the number of records in the primary key field. In the following figure, the primary key is the ProductID value in Northwind's Products table. Notice that the result of the Count() function in the form's header matches the form's Navigation button — there are 77 records. The Count() expression will also accommodate a filtered recordset, as shown below. In this case, there are 13 records in the filtered recordset. In both cases, the Count() f here for a quick overview of the site Help Center Detailed answers to any questions you might have Meta http://stackoverflow.com/questions/19278612/how-to-display-a-query-record-count-in-a-form-control Discuss the workings and policies of this site About Us Learn http://allenbrowne.com/RecordCountError.html more about Stack Overflow the company Business Learn more about hiring developers or posting ads with us Stack Overflow Questions Jobs Documentation Tags Users Badges Ask Question x Dismiss Join the Stack Overflow Community Stack Overflow is a community of 6.2 million programmers, just like ms access you, helping each other.

I would like to display the total # of count records in records returned to the form. I have added a unbound text field to the footer in the form that is displaying the controls and resulting records. I tried the following expressions in the text field, both of which result in #error: =Count([qrnname]![fieldtocount]) =DCount([qrnname]![fieldtocount]) This should be simple. ms-access ms-access-2007 access-vba share|improve this question edited Oct 9 '13 at 17:39 HansUp 79.3k114371 asked Oct 9 '13 at 17:18 jamesTheProgrammer 1,38011729 add a comment| 3 Answers 3 active oldest votes up vote 4 down vote accepted DCount requires string values for its arguments. Assuming fieldtocount is the name of a field returned by the named query qrnname, use this as your text box's Control Source ... =DCount("[fieldtocount]", "qrnname") Since that query depends on criteria selected in the form, Requery the text box whenever those criteria change to update the count displayed in the text box. share|improve this answer answered Oct 9 '13 at 17:37 HansUp 79.3k114371 add a comment| up vote 1 down vote use this =DCount([fieldtocount]![qrnname]) The syntax fo 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 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 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 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 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. For details of how to do this with subreports, see Bring the total from a subreport onto a main report. Home Index of tips Top
