I am trying to develop a spreadsheet that can locate corresponding records in an external data source. So, let\'s say I have Column A with a list of identity values. I wan
So to do this I would create a UDF and have the backend of that function connecting to your access database. Something like this:
Public Function countMyTable(IDValue As Double) As Long
'Requires:// Microsoft Access 16.0 Object Library
'Requires:// Microsoft Office 16.0 Access database engine Object Library
Dim db As DAO.Database
Dim rs As DAO.Recordset
Set db = Access.DBEngine.Workspaces(0).OpenDatabase(DBFilePath, False, False)
Set rs = db.OpenRecordset("SELECT COUNT(1) FROM MyTable WHERE IDValue = " & IDValue, dbOpenSnapshot)
rs.MoveLast
countMyTable = rs(0)
db.close
End Function
Hope this helps, TheSilkCode
I would use a parameterized query (where IDVALUE=?), but that prompts me to input the parameter value
From what you mentioned I understand you are using MS Query and you need to follow the following steps
Steps to make a parameterized query in Excel use a cell value as parameter

Use the query wizard to create or edit queries it is not very useful in most cases 


view menu and uncheck tables. This removes the graphically representation in query window and makes it easier to alter you sql query 
SQL button below the format menu in query window. A pop up comes where you can edit the query as you wish. Make sure to add question mark(s) for the parameter(s) you want. 


exit button below the view menu in query window. Then the query window closes and Import Data pop up comes asking where in excel to display the result. Choose accordingly

Definition tab. Click on Parameters button in bottom of the pop up next to edit query button
Parameters pop up comes displaying the parameters used in the query. Here you must select the Get the value from following cell radio button to select the value of cell as the parameter for the query. Click OK and you should be done.

This method is for people with no VBA experience. If you know VBA then refer to this answer to achieve the something similar using VBA.
