I'm having some issues with a union query which contains duplicate records. The SQL for the query is below:
Code:
SELECT tblCustomer.OrganizationFK, tblCustomer.ShopNameFK, tblCustomer.OfficeSymFK, tblCustomer.LastName, tblCustomer.FirstName, tblFacilityMgr.BuildingFK, tblRooms.RoomsPK, tblBuilding.BuildingName, tblRooms.RoomName, tblSecOptions.SecName, tblCabinet.CabinetName, tblEquipment.CabinetFK, tblEquipment.EquipmentNameFK, tblEquipment.EquipmentBrandFK, tblEquipment.EquipmentNetworkTypeFK, tblEquipment.EquipmentIP, tblEquipment.SerialNumFROM tblSecOptions INNER JOIN (((tblBuilding INNER JOIN (tblCustomer INNER JOIN tblFacilityMgr ON tblCustomer.CustomerPK = tblFacilityMgr.CustomerFK) ON tblBuilding.BuildingPK = tblFacilityMgr.BuildingFK) INNER JOIN tblRooms ON tblBuilding.BuildingPK = tblRooms.BuildingFK) INNER JOIN (tblCabinet LEFT JOIN tblEquipment ON tblCabinet.CabinetPK = tblEquipment.CabinetFK) ON tblRooms.RoomsPK = tblCabinet.RoomsFK) ON tblSecOptions.SecOptionPK = tblRooms.SecOptionFK
UNION SELECT tblCustomer.OrganizationFK, tblCustomer.ShopNameFK, tblCustomer.OfficeSymFK, tblCustomer.LastName, tblCustomer.FirstName, tblRooms.BuildingFK, tblRooms.RoomsPK, tblBuilding.BuildingName, tblRooms.RoomName, tblSecOptions.SecName, tblCabinet.CabinetName, tblEquipment.CabinetFK, tblEquipment.EquipmentNameFK, tblEquipment.EquipmentBrandFK, tblEquipment.EquipmentNetworkTypeFK, tblEquipment.EquipmentIP, tblEquipment.SerialNum
FROM tblSecOptions INNER JOIN (((tblBuilding INNER JOIN tblRooms ON tblBuilding.BuildingPK = tblRooms.BuildingFK) LEFT JOIN (tblCabinet LEFT JOIN tblEquipment ON tblCabinet.CabinetPK = tblEquipment.CabinetFK) ON tblRooms.RoomsPK = tblCabinet.RoomsFK) INNER JOIN (tblCustomer INNER JOIN tblRoomsPOC ON tblCustomer.CustomerPK = tblRoomsPOC.CustomerFK) ON tblRooms.RoomsPK = tblRoomsPOC.RoomsFK) ON tblSecOptions.SecOptionPK = tblRooms.SecOptionFK;
I need to make the Building ID and the Room ID (tblFacilityMgr.BuildingFK, tblBuilding.BuildingPK, tblRoomsPOC.RoomsFK, tblRooms.RoomsPK) unique and concatenate all other related data, to remove duplicates.
Below is the code I found online for a concatenate function. I cannot seem to figure out how to apply it to my query. It has something to do with "ConcatRelated("strField", "strTable")" Also I don't believe that will work to concatenate all the fields. it looks like it only handles one. Thank you so much for your help.
Code:
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:
Dim rs As DAO.Recordset 'Related records
Dim rsMV As DAO.Recordset 'Multi-valued field recordset
Dim strSql As String 'SQL statement
Dim strOut As String 'Output string to concatenate to.
Dim lngLen As Long 'Length of string.
Dim bIsMultiValue As Boolean 'Flag if strField is a multi-valued field.
'Initialize to Null
ConcatRelated = Null
'Build SQL string, and get the records.
strSql = "SELECT " & strField & " FROM " & strTable
If strWhere <> vbNullString Then
strSql = strSql & " WHERE " & strWhere
End If
If strOrderBy <> vbNullString Then
strSql = strSql & " ORDER BY " & strOrderBy
End If
Set rs = DBEngine(0)(0).OpenRecordset(strSql, dbOpenDynaset)
'Determine if the requested field is multi-valued (Type is above 100.)
bIsMultiValue = (rs(0).Type > 100)
'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
rsMV.MoveNext
Loop
Set rsMV = Nothing
ElseIf Not IsNull(rs(0)) Then
strOut = strOut & rs(0) & strSeparator
End If
rs.MoveNext
Loop
rs.Close
'Return the string without the trailing separator.
lngLen = Len(strOut) - Len(strSeparator)
If lngLen > 0 Then
ConcatRelated = Left(strOut, lngLen)
End If
Exit_Handler:
'Clean up
Set rsMV = Nothing
Set rs = Nothing
Exit Function
Err_Handler:
MsgBox "Error " & Err.Number & ": " & Err.Description, vbExclamation, "ConcatRelated()"
Resume Exit_Handler End Function
Edit: after more searching, I found this: http://allenbrowne.com/func-concat.html
It does explain a lot and I'll definitely play around with it tomorrow, but I'm not sure how I'll implement it in such a large union query. It looks simple for just a couple fields.
