Add query data to existing export function

[FoolzRailer]

Hello

I'm trying to add some data to an VBA-export function I created a while ago. Basically I need to add the data from the table Stik_Samling to the bottom of my first export function with OpenRecordset VBK_Knude.

However I've run into a few issues, the number of columns in Stik_Samling can vary for each row, so it might not just be 3 as shown in the example, it could be 2 or 5, so needs to loop through this. Then it needs to be placed under the correct KnudeID/Knudenavn/$Knude in the export, so it matches. I tried on my own first, with the strSql_ bit I've since commented out in the code.

Any help would be much appreciated! I've added the code and some pictures.

Public Function Export_VBK_Samlet_v1()

    Dim foundXY As Boolean
    Dim ff As Long

End Function

Datasheet view followed by the Design view of the query of VBK_Knude. Can also add the SQL if needed. I've also shown the Stik_Samling below, that needs the data joined in my export.

The desired output should look like this as a .vbk file (can be opened as txt in notepad just fyi):

I would break this code into subroutines. Dealing with this as a single routine makes it hard to understand, hard to maintain, hard to debug, etc...

As a rule of thumb, one subroutine should do one thing. If you need to open a second recordset, for instance, do that in a subroutine. If you need to enumerate all the fields in a row, do that in a subroutine. If you need to return formatted values, write a function.

Doing all these different tasks in a single procedure is like juggling. If you want to become a juggler, ok, but typically the most important objective is to not drop anything. To not drop anything, deal with each single task, one at a time, in a Sub, Function or Property.

Happy coding,
