why won't "Dim rs As DAO.Recordset" compile

[TyeReece]

I am a novice so I apologize if this is a dumb question. Long story short. I am trying to combine multiple records in a query. I have an ID field and a field of names of diagnoses. My goal is to have one row per ID with the diagnoses combined in one field. Everything I read on line says Allen Browne's concatrelated() function is the way to go. So I paste the function into a module and when I try to compile it stops at "Dim rs As DAO.Recordset". Here is the link to his site if you need it. http://allenbrowne.com/func-concat.html I have also pasted the code below. Any help is appreciated.

Public Function ConcatRelated(strField As String, _
    strTable As String, _
    Optional strWhere As String, _
    Optional strOrderBy As String, _
    Optional strSeparator = ", ") As Variant
On Error GoTo Err_Handler
    'Purpose:   Generate a concatenated string of related records.
    'Return:    String variant, or Null if no matches.
    'Arguments: strField = name of field to get results from and concatenate.
    '           strTable = name of a table or query.
    '           strWhere = WHERE clause to choose the right values.
    '           strOrderBy = ORDER BY clause, for sorting the values.
    '           strSeparator = characters to use between the concatenated values.
    'Notes:     1. Use square brackets around field/table names with spaces or odd characters.
    '           2. strField can be a Multi-valued field (A2007 and later), but strOrderBy cannot.
    '           3. Nulls are omitted, zero-length strings (ZLSs) are returned as ZLSs.
    '           4. Returning more than 255 characters to a recordset triggers this Access bug:

    'Loop through the matching records
    Do While Not rs.EOF
        If bIsMultiValue Then
            'For multi-valued field, loop through the values
            Set rsMV = rs(0).Value
            Do While Not rsMV.EOF
                If Not IsNull(rsMV(0)) Then
                    strOut = strOut & rsMV(0) & strSeparator
                End If

    Loop
    rs.Close

    lngLen = Len(strOut) - Len(strSeparator)

You did not mention if you had the reference checked. Go to tools reference and check Microsoft DAO 3.6 Library or some thing of the effect.
If you also lookup how excel deals with early binding and late binding this may clear up some of the mystery.

What version of Access are you using?

 

[TyeReece]

Unfortunately, I do not understand what you mean by having the reference checked. I looked in Access Tools and don't see anything about Microsoft Library.

From the VB Editor, select Tools then References. It will list all the libraries and show which ones are selected.
A "Microsoft DAO..." library needs to be selected. If one is not, then select it from the list.

Note that on my access the library I have for Access is just Microsoft Office 15.0 Access database engine Object Library.

Edit: In your case it would probably be 16.0 that applies.



If you are having trouble list here what IS checked.

THANK YOU! It compiled without an issue. This will save me so much time. Thanks!

OK. my query runs but doesn't concatenate the field I am trying to combine. I get the ID and every diagnosis attached to them in separate rows. Below is the code I have that runs. I think the issue I am having has to do with third and/or forth arguments of the concatrelated function (bolded below). I have tried to use the RevNum and ReviewNum in place of the bolded code and it doesn't work. Any ideas on what I am doing wrong?

SELECT 
	[Data Request Dr Lohr TBL].ID, 
	[Data Request Dr Lohr TBL].RevNum, 
	ConcatRelated("DSM_IV","DSM_IV_List","DSMIV_ID = " & [DSM_IV_List]![DSMIV_ID]) AS Diagnoses
FROM 
	([Data Request Dr Lohr TBL] 
	INNER JOIN DSM_IV_Diagnosis 
	ON [Data Request Dr Lohr TBL].[RevNum] = DSM_IV_Diagnosis.ReviewNum) 
	INNER JOIN DSM_IV_List 
	ON DSM_IV_Diagnosis.DSMIV_ID = DSM_IV_List.DSMIV_ID;

You probably have to supply sample data from the tables involved. Mostly likely the function is doing what it is supposed to and you have either set it up wrong or are just using it incorrectly or in a situation where it doesn't apply.
