How to retrieve a count of all records where a Date field is within the next year, and store it in a variable? - date

Question

I am fairly new to MS Access, but have a decent understanding of databases, with some knowledge of SQL.
I am creating a database in Access. On a main form that users will see first, I need to display a count of all records from my Case table, which have a StatuteOfLimitation date that is within the next year.
My goal was to create a label describing the information, with a button below it. The button will open a report of all of the records (this part is working fine), and I wanted the caption for the button to display the total count of how many records meet the criteria.
The only way I can think to do it, is to retrieve the count and store it into a variable. From there, I should be able to set the caption to the variable value.
I have seen a few methods of retrieving a count and storing it in a variable, but all that I found only stored a count of EVERY record, without filtering for the date range.
This was the best that I could think of, but it is not working:
Private Sub Form_Load()
Dim oneYearFromToday As TempVars
SET TempVars!oneYearFromToday = (SELECT COUNT(StatuteOfLimitation) FROM Case
WHERE StatuteOfLimitation <= DateAdd("yyyy", 1, Date());
End Sub

Answer 1

DCount() provides a simple approach for "How to retrieve a count of all records where a Date field is within the next year"
Dim lngCount As Long
lngCount = DCount("*", "Case", "[StatuteOfLimitation] <= DateAdd('yyyy', 1, Date())")
Then you can use that count in your command button's Caption property. Say the button is named cmdOpenReport ...
Me!cmdOpenReport.Caption = "Report " & lngCount & " cases"
If you want the count in a TempVar instead of a regular Long variable, declare it As TempVar (just one) instead of As TempVars (a collection). And when you assign the value to it, don't use Set.
Dim oneYearFromToday As TempVar
TempVars!oneYearFromToday = DCount("*", "Case", "[StatuteOfLimitation] <= DateAdd('yyyy', 1, Date())")

I probably wouldn't use a tempvar to store your variable. you can try something like below using the DAO.
Private sub Form_Load()
dim rst as dao.recordset
dim strSQL as string
'Creates query string
strsql = "SELECT Count(StatueOfLimitation) as RecordCount " & _
"FROM Case " & _
"WHERE (((StatueOfLimitation) <= DateAdd('yyyy',1,date())));"
'Opens the query string into a recordset
set rst = currentdb.openrecordset(strsql)
'Change Labelnamehere isnto the name of the label control on your form
'Change what ever saying you want here to something you want the label to display
me.labelnamehere.caption = "What ever saying you want here " & rst![RecordCount] 'Don't need a variable storage is you can use the result here
rst.close 'closes recordset
set rst = nothing 'Clears memory
EndCode: 'Ensures clean up is successful
If not rst is nothing then
rst.close
set rst = nothing
end if
end sub
If this doesn't work for you, please let me know and I'll do some more digging.

I'm not able to comment on HansUp's answer, but to change a label caption in VBA you need to open the form in Design view. It's not something I typically do, my personal preference is to use an unbound text box with labels that don't change, but I have done it in one database to update the time/date and user for the last email sent.
The code would look like this:
DoCmd.OpenForm "yourformname", acDesign, , , , acHidden
Forms![yourformname]![yourlabelname].Caption = "There are " & TempVars!onYearFromToday & " cases to view."
DoCmd.Close acForm, "yourformname", acSaveYes
DoCmd.OpenForm "yourformname", acNormal

It's a bad idea to use a button for info display. That's not the purpose of a button.
Use a textbox and set its ControlSource:
=DCount("*","[Case]","[StatuteOfLimitation]<=DateAdd("yyyy",1,Date()))
It will fill by itself, and the button is free to open the report at any time.
