VBA ADODB- Select query using the excel sheet of the same workbook as Database

I am novice in VBA so please don't mind if the question is of low level.I am trying to run a SQL query where the data has to be extracted from one of the sheets of the same workbook.

enter image description here

SQL = "Select ProductNumber from [sData$] where ProductSource = " & pSource & "

'pSource is a string that stores Product Source
'sdata is a sheet named as Data in the workbook

dataPath = ThisWorkbook.Fullname

'Not sure if this is the value I shall send as datapath in getData function

Set rst = getData(dataPath,SQL)
rst.Open

The getData function is defines as below

Public funtion getData(path as String, SQL as string) as ADODB.Recordset
Dim rs as ADODB.Recordset
Set cn = New ADODB.Connection
Set rs = New ADODB.Recordset
cn.Open ("Provider= Microsoft.Jet.OLEDB.4.0;" & _
           "DataSource= " & path & ";"&_
            "Extended Properties=""Excel 8.0;HDR=Yes;FMT=Delimited;IMEX=1;""")
rs.ActiveConnection =cn
rs.Source= SQL
Set getData =rs
End Function

Now after I get the numbers from Data sheet, I need to find the corresponding ProductCompany from Relation sheet. 9 is for Amul, 5 is for Nestle and so on.

Relation:

enter image description here

I am not sure how to do that. The numbers corresponds to their respective Product company in order.

Take a look at the below example showing how to create ADODB connection to this workbook, get ADODB recordset from SQL query, retrieve key - value pairs from relation sheet, create and populate a dictionary, and output the values from the recordset and the corresponding values from the dictionary:

Option Explicit

Sub Test()

    Dim oCn As Object
    Dim oRs As Object
    Dim aKeys
    Dim aItems
    Dim i As Long
    Dim oDict As Object
    Dim dProdNum

    ' create ADODB connection to this workbook
    Set oCn = CreateObject("ADODB.Connection")
    oCn.Open _
        "Provider=Microsoft.Jet.OLEDB.4.0;" & _
        "DataSource='" & ThisWorkbook.FullName & "';" & _
        "Extended Properties=""Excel 8.0;HDR=Yes;FMT=Delimited;IMEX=1;"";"
    ' get ADODB recordset from SQL query
    Set oRs = oCn.Execute("SELECT DISTINCT ProductNumber FROM [Data$] WHERE ProductSource = 'A1'")

    ' retrieve key - value pairs from relation sheet
    With ThisWorkbook.Sheets("Relation")
        aKeys = Split(.Range("B1"), ",")
        aItems = Split(.Range("B2"), ",")
    End With
    ' create and populate a dictionary
    Set oDict = CreateObject("Scripting.Dictionary")
    For i = 0 To UBound(aKeys)
        oDict(Trim(aKeys(i)) + 0) = Trim(aItems(i))
    Next

    ' output the values from the recordset and the corresponding values from the dictionary
    oRs.MoveFirst
    Do Until oRs.EOF
        dProdNum = oRs.Fields(0).Value
        Debug.Print dProdNum & " - " & oDict(dProdNum)
        oRs.MoveNext
    Loop

End Sub

The output for me is as follows:

4 - Britanica
5 - Nestle
9 - Amul

Note, connection string in the above code shown for .xls file. In case .xlsm you should use:

    oCn.Open _
        "Provider=Microsoft.ACE.OLEDB.12.0;" & _
        "Data Source='" & ThisWorkbook.FullName & "';" & _
        "Extended Properties=""Excel 12.0 Macro;HDR=Yes;FMT=Delimited;IMEX=1;"";"
