Access Convert Columns into Rows

Posted on 2016-08-04

Last Modified: 2016-08-04
I have a access table that was created from an import of a Excel spreadsheet.  All the DueDates for the part are represented as column names.  I need to essentially "UNPIVOT" this table and put the column names as rows.  The desired output would look like this
ItemNumber |DueDate | Qty
A |07-11-16 |1
A | 07-18-16 | 1

Attached is a copy of the database with this table.  Keep in mind that the way to UNPIVOT should be dynamic.  Each week we import a new spreadsheet and the column names will be different, so we need to UNPIVOT after each import of the spreadsheet.

Dumb question: can you not copy-and-paste-special-transpose the spreadsheet before import?

You can use PowerQuery in Excel to UNPIVOT, but it's too many steps for the different users to perform consistently.  The thought was to move it into Access so with a button and some VBA the columns can be unpivoted or transformed into rows.

You can use this function:
Public Function TransformImport()

    Dim db  As DAO.Database
    Dim rss As DAO.Recordset
    Dim rst As DAO.Recordset
    Dim fld As Integer
    Set db = CurrentDb
    Set rss = db.OpenRecordset("tblForecastImport")
    Set rst = db.OpenRecordset("Select Top 1 * From tblForecast")
    While rss.EOF = False
        For fld = 2 To rss.Fields.Count - 1
                rst!ItemNumber.Value = rss!ID.Value
                rst!DueDate.Value = DateValue(rss.Fields(fld).Name)
                rst!Qty.Value = rss.Fields(fld).Value
    Set rst = Nothing
    Set rss = Nothing
    Set db = Nothing
End Function

Open in new window

as shown in the attached demo.
