Help With Recordcount Command
Jul 14, 2006I am trying to count how many records has a table with a special value (SolicitaçãoID.Text) but I keep getting error:
Compile Erro:
User-Defined not defined
And it goes to this line: Dim db As DAO.Database
This is the command:
Private Sub CmdAmostra_Click()
Dim db As DAO.Database
Dim rs As DAO.Recordset
Dim intResult As Integer
Dim strSQL As String
Set db = CurrentDb
SolicitaçãoID.SetFocus
strSQL = "SELECT COUNT (*) As RecordCount FROM Protocolo_O where SolicitaçãoID=" & SolicitaçãoID.Text
Set rs = db.OpenRecordset(strSQL, dbOpenSnapshot)
intResult = rs("RecordCount")
MsgBox intResult
Amostras.SetFocus
Amostras.Text = intResult
rs.Close
db.Close
End Sub
Well i have no clue what that error means and why.
Thanks for the Help

RecordCount Please Help! Im Stuck
Oct 6, 2006Thanks for looking at my post. What I have done is this, i have built a custom search form for my access database. What i need is a textbox that shows how many records will show up if the user clicks generate form.. I want this textbox to update every time the person changes his search criteria. For example
the person wants to search by address, by typing in
Gold into the address textbox the recordcount textbox would show the user if he were to press generate form he would get
1200 records
now if he changes the address to
GoldStone -- the recordcount textbox would then update to show only
14 records would be shown if he/she generated the form...
Here is my current code
***********
Set db = CurrentDb
Set qdf = db.QueryDefs("MainDB_Search")
For Each prm In qdf.Parameters
prm.Value = Eval(prm.Name)
Next prm
Set rs = qdf.OpenRecordset(dbOpenDynaset)
rsCount = rs.RecordCount
MsgBox (rsCount)
txtGenerateReport.Value = rsCount
************
Now the problem with this code is that it works the first time the user types in search criteria, however when he/she tries to change it from Gold to Goldstone -- nothing happens, it runs the code above and returns 1200 records instead of the correct 14...
Please help :)
Thanks

Queries :: Update A Query Based On Results From Another Query Using Count Function
Apr 2, 2013I run a physical therapy office and patients come in for treatment either 3, 4 or 5 times per week. My database is used to track these frequencies (among other things).
I have 3 queries which count how many patients come in 5, 4 and 3 times/week.
In my main table I have fields called "how many 5's", "how many 4's" and "how many 3's".
I have tried to design an update query which will update those fileds in my main table to reflect the counts in the 3 queries mentioned above.
(I'm not using SQL view, I'm using the query design view)
In the "update to:" row, I use the Build function and locate the count I'm looking for.
Problem: when I run the query I get the error: Operation must use an updateable query.
Queries :: Count Query For QBF
Apr 27, 2015I have recently been working on a database that is meant to be quite user friendly. It contains two tables, one that lists 'trainees' and another that lists 'job applications' in a 'one to many' type relationship. It is designed to monitor Job applications being made by people doing courses here. So far, I have created a very practical form for data entry. I've created a QBF to allow the user to filter the Job Applications quite substantially. I'm trying to build a form that allows the same criteria to be entered, but that counts the number of Job Applications, and then creates a pie chart that subdivides the applications by 'source of application' (i.e. Indeed.com, Family, Newspaper'), or Industry of the potential employer.
For example, I would like to be able to select a programme or course that someone is on, their starting date, a date range for the application and some other details- i.e. Select an Industry then view a pie charts for the source of those applications and vice versa.
I've created a form for this, with a button for 'Source' and one for 'Industry' the two different pie chart types I would like to be able to select. I have created two separate query by forms for each, with the buttons linking to the respective Macro. The problem I'm having is that the query seems to ignore the WHEN criteria completely.
SELECT COUNT([Job Applications].[Application ID]), [Job Applications].source
FROM [Job Applications] INNER JOIN Trainees ON [Job Applications].[Trainee ID] = Trainees.[Trainee ID]
WHERE (
[Job Applications].[Application Date] > forms!CustomChart!DateAfter OR
forms!CustomChart!DateAfter IS NULL) AND
[code]...
Subform Recordcount Problem
Aug 25, 2006I have several bound subforms whose recordsources are based on querydefs...
I use the following code in the OnCurrent event of the main form to count the number of records on a subform,
Me.mysubformname.Form.RecordsetClone.RecordCount
but for some reason, one particular subform won't give me the correct count... the only difference I can see between the problem subform and the others is that it is populated by a union query... any reason why that would be causing the problem? Any other thoughts?
Thanks in advance,
Scott
Combo Box Versus List Box?
Sep 9, 2006This might be a silly question - I appologize in advance if it is. - let me know! :) I have searched a bit and found nothing quite along the same lines.
I have realized that I only use Combo boxes, avoiding List boxes entirely. I had some early difficulties with List Boxes that I can't recall now, yet a lot of my combo boxes are limited to list. Most posts I read on this forum seem to mention Combo rather than List boxes (I may have a bias here?).
It looks like a combo box that is limited to list is pretty much a list box. If this is right, is there ever any advantage to using a list box that I am missing out on?
From Access help:
List boxes: What they are and how they work
In many cases, it's quicker and easier to select a value from a list than to remember a value to type. A list of choices also helps to ensure that the value that's entered in a field is correct.
The list in a list box consists of rows of data. In a form, a list box can have one or more columns, which can appear with or without headings. If a multiple-column list box is bound, Microsoft Access stores the values from one of the columns. In a data access page, a list box has one column without a heading.
You can use an unbound list box to store a value that you can use with another control. For example, you could use an unbound list box to limit the values in another list box or in a custom dialog box. You could also use an unbound list box to find a record based on the value you select in the list box.
On a form, you can use a combo box instead of a list box; it takes up less room, and you can type new values in it, as well as select values from a list. Learn about combo boxes on forms.
On a data access page, you can use a drop-down list box instead of a list box; it takes up less room; however, you can't type new values in it. Learn about drop down list boxes on data access pages.
Combo boxes: What they are and how they work
In many cases, it's quicker and easier to select a value from a list than to remember a value to type. With a combo box, you can do either without using too much space on a form. A combo box is like a text box and a list box combined.
When you enter text or select a value in a combo box, if the combo box is bound, the entered or selected value is inserted into the field that the combo box is bound to.
The list in a combo box consists of rows of data. Rows can have one or more columns, which can appear with or without headings. If a multiple-column combo box is bound, Microsoft Access stores the values from one of the columns.
You can use an unbound combo box to store a value that you can use with another control. For example, you could use an unbound combo box to limit the values in another combo box or in a custom dialog box. You could also use an unbound combo box to find a record based on the value you select in the combo box.
Combo boxes have a LimitToList property that you can use to control whether any value can be entered in the list, or only text that matches one of the values in the list can be entered.
If you have room on your form and you want a list to appear at all times, or if you always want to limit data entries to values in the list, you might want to use a list box instead of a combo box. For more information on list boxes, click .
Is the last para from above:
If you have room on your form and you want a list to appear at all times, or if you always want to limit data entries to values in the list, you might want to use a list box instead of a combo box. For more information on list boxes, click the only advantage?
RecordCount Problems With ADODB 2.6
Feb 28, 2005The company I work for remains on the 2.6 version of the various MDAC components. Unfortunately, upgrading is not an option that I can control. So....
When I open a recordset which DOES contain records, I often return a RecordCount of -1. EOF is false, so that is working, and I am able to use that to get around part of my problem. Where I need the count after iterating through the recordset, I am able to use an iCounter variable to get that. I have tried using MoveLast, MoveFirst, etc. before calling for RecordCount, but that does not help.
In many instances having the count BEFORE going through the recordset would be very helpful. Has anyone else ever encountered this problem? Anyone devise a workaround?
Thanks in advance for any help!

Queries :: One To Many Join / Count Query
Oct 16, 2013I am looking to create a query using a main table and 3 related tables to produce a count of evaluations completed and evaluations passed by month (using the 3 related tables) and site location (using main table) which is joined by agent name. I have the following so far but:
Code:
SELECT
[MainTbl].Location,
Format$([Tbl1].[EvaluationDate],'mmmm yyyy') AS [EvaluationPeriod],
Count([Tbl1].[Agent Name]) AS [NoCompleted],
Count(IIF([EvaluationScore]>=0.9,0)) AS [NoPassed]
[Code] .....
But I get the following results:
Code:
Location EvaluationPeriod NoCompleted NoPassed
Location1 Month1 Tbl1.NoCompleted Tbl1.NoPassed
Location1 Month1 Tbl2.NoCompleted Tbl2.NoPassed
Location1 Month1 Tbl3.NoCompleted Tbl3.NoPassed
Location2 Month1 Tbl1.NoCompleted Tbl1.NoPassed
Location2 Month1 Tbl2.NoCompleted Tbl2.NoPassed
Location2 Month1 Tbl3.NoCompleted Tbl3.NoPassed

Curious On Rich's Recordcount Advise
Nov 4, 2005Rich helped Latex88 a little further down and the advise given was:
"=Count(*) in the control source of a textbox in the subform footer will do it, no vba is needed"
I tried this out out on a few of my subforms and it worked on all but one. The recordsource of the one that it does not work on is based on a query. When I changed the recordsource to a table then the recordcount works.
Curious as to why and is there a work around?
Thanks a head of time,

Access 'project' Versus 'database'
Apr 5, 2005I seem to be missing an understanding of the difference between a project and a database. I am using a .mdb and writing code with success until I try to use the recordset feature which I took from my "VBA programming" book.
My code is simple...
Dim db As Database
Dim rec As Recordset
Dim strSQL As String
Dim intCount As Integer
Dim listEmails As String
strSQL = "SELECT Email from Member"
db = CurrentDb()
rec = db.OpenRecordset(strSQL, dbOpenSnapshot)
Do Until rec.EOF
listEmails = listEmails & Chr$(10) & rec(Email)
Loop
rec.Close
MsgBox listEmails
But when I run it I get a compile error because in line 1 the term 'database' is only a class in "a project".
Can anyone explain the issue and better still the solution.
Thanks

Queries :: Query To Count Corresponding Records In Another Table
May 3, 2013I'm trying to do a query to count corresponding records in another table. It works except for returning zeros. I've tried using NZ and switching the type of join, but to no avail.
Here's what I have:
Query A has 3 columns (FU kids)
AlphaID
DtcCtr (a Location Code)
DlsDtc (a Date of change)
Table A has many columns, but I'm only using a few. (dbo_MNCPSTNote)
AlphaID
DtcCtr (the same Location Code)
ServDate (the date I'm trying to count)
Here's what I have:
SELECT [FU kids].AlphaID, [FU kids].DtcCtr, Count(dbo_MNCPSTNote.ServDate) AS CountOfServDate
FROM dbo_MNCPSTNote RIGHT JOIN [FU kids] ON dbo_MNCPSTNote.AlphaID = [FU kids].AlphaID
WHERE (((dbo_MNCPSTNote.Center)=[FU kids]![DtcCtr])) OR (((dbo_MNCPSTNote.ServDate)>[FU kids]![DlsDtc]))
GROUP BY [FU kids].AlphaID, [FU kids].DtcCtr;
I want to know the count, including zero, of the number of records based on ServDate for each AlphaID in Query A.
I didn't create the tables and have no control over how they are designed/organized.
Queries :: Select Count And Group Query
Sep 19, 2014I have built a database that shows the purchase of items that have serial numbers, and so are unique. The database shows the purchase oe each item, and subsequent sale, including "Date In" and Date Out".
Each "item" however has a unique transaction reference (Stock No.) I would like to be able to show what items are currently in stock, and therein lies my problem.I am able to use a select count to find all the instances where the stock number there are two stock numbers (ie In and then Out), but have been unable to find a way to filter the records in a query, to show the stock currently held.
only Single instances of the "Stock No." appear in a table, as that would show the current stock held.I have tried numerous ways to achieve this but I have reached a dead end. I am not experienced in writing with SQL.
Queries :: Running Count Over Group In Query
May 11, 2014I want to do something within Access 2010, but unfortunately I have only partly succeeded so far..
So far this thread has been very useful: [URL] ....
It (almost) completely explains my problem. I have a database with suppliers that participated in tenders. Now I would like to, on a chronological basis, make a "running count" on how often a supplier participated in these tenders (on the basis of supplierID).
In the attachment you can see an example of how the data in my table looks like. With the following function, which I got out of the thread above, I have already been able to make a running count on how often a supplier participated (its "experience").
The function:
DCount("*";"[Table1]";"Supplier_ID = " & [Supplier_ID] & " AND ID <= " & [ID])
So far, so good. But I would like to go for an extra addition, since now the period on which this running count is based is the entire data set, which runs from 2006 till 2013. In other words, Access starts counting from the first record and ends at record 300.000. What I would like to do is to base this running count on the two years before (and including) the tender's Decision_Date, which is also in the dataset.
Example: a specific supplier participated in a tender that took place on 10 december 2010. Know I would like to know its "experience" with tenders, by means of a running count, based on the period from 10 december 2008 till 10 december 2010.

Queries :: Count The Amount Of Times A Name Appears In A Query?
May 31, 2013I have a log in table that counts every time a user logs onto the database. Each time a user logs in it adds another entry to a table.
I have built a query to display the user name and date of log in so I could display this information in a report. The report is now getting rather long, and I am looking for a way to display each users name and have the total number of times they have logged in, not display each time they have logged in separately.
The Query has two fields "Agent Name" and "Logger Date"
The report displays the data as follows
Agent Name Logger Date
User 1 26/5/13
User 1 26/5/13
User 1 27/5/13
User 2 28/5/13
What I would like to do is have a report listing each users name, with a column showing how many times they have logged on. e.g.
User Name Login Count
User 1 3
User 2 1
