Importing Excel worksheet range to Ms Access Table - excel

Good Afternoon,
I have created a Macro that uploads data to a access database ( both on my desktop). The problem is it I keep getting errors when I try to expand the range.
I presumed it would be something simple but seems to be something I am overlooking.
here is the code - basically I would like to include the column or set it to a dynamic range? can you please help?
Sub AccessCode()
Application.ScreenUpdating = False
Dim db As Database
Dim rs As DAO.Recordset
Set db = OpenDatabase("C:\Users\user\Desktop\Test Copy.accdb")
Set rs = db.OpenRecordset("Fact Table", dbOpenTable)
rs.AddNew
rs.Fields("GUID") = Range("g2").Value
rs.Fields("StageID") = Range("h2").Value
rs.Fields("Sync Date") = Range("i2").Value
rs.Fields("Forecast HP") = Range("j2").Value
rs.Fields("Owner Id") = Range("k2").Value
rs.Fields("Recent Modified Flag") = Range("L2").Value
rs.Fields("Upload Date") = Range("M2").Value
rs.Update
rs.Close
db.Close
Application.ScreenUpdating = True
MsgBox " Upload To PMO Database Successful."
End Sub

You can use a query instead of iterating through a recordset:
Sub AccessCode()
Application.ScreenUpdating = False
Dim db As Database
Dim rs As DAO.Recordset
Set db = OpenDatabase("C:\Users\user\Desktop\Test Copy.accdb")
db.Execute "INSERT INTO [Fact Table] ([GUID], [StageID], etc) " & _
"SELECT * FROM [SheetName$G:M] " & _
"IN """ & ActiveWorkbook.FullName & """'Excel 12.0 Macro;HDR=No;'"
End Sub
This has numerous advantages, such as often being faster because you don't have to iterate through all the fields.
If you would trigger the import from Access instead of Excel, you wouldn't even need VBA to execute the query.

Change the rs section to this one:
With rs
.addnew
!GUID = Range("g2").Value
!StageID = Range("h2").Value
'...etc
.Update
End With
MSDN source
Use the AddNew method to create and add a new record in the Recordset object named by recordset. This method sets the fields to default values, and if no default values are specified, it sets the fields to Null (the default values specified for a table-type Recordset).
After you modify the new record, use the Update method to save the changes and add the record to the Recordset. No changes occur in the database until you use the Update method.
Edit:
This is how your code should look like, when you change the rs section with the code above:
Sub AccessCode()
Application.ScreenUpdating = False
Dim db As Database
Dim rs As DAO.Recordset
Set db = OpenDatabase("C:\Users\user\Desktop\Test Copy.accdb")
Set rs = db.OpenRecordset("Fact Table", dbOpenTable)
With rs
.addnew
!GUID = Range("g2").Value
!StageID = Range("h2").Value
'...etc
.Update
.Close
End With
Application.ScreenUpdating = True
MsgBox " Upload To PMO Database Successful."
End Sub

Just thought I'd add in an alternative to #Erik von Asmuth's excellent answer. I use something like this in a real project. It's a little more robust for importing a dynamic range.
Public Sub ImportFromWorksheet(sht As Worksheet)
Dim strFile As String, strCon As String
strFile = sht.Parent.FullName
strCon = "Excel 12.0;HDR=Yes;Database=" & strFile
Dim strSql As String, sqlTransferFromExcel As String
Dim row As Long
row = sht.Range("A3").End(xlDown).row
Dim rng As Range
sqlTransferFromExcel = " Insert into YourTable( " & _
" [GUID] " & _
" ,StageID " & _
" ,[sync Date] " & _
" ,[etc...] " & _
" ) " & _
" SELECT [GUID] " & _
" ,StageID " & _
" ,[sync Date] " & _
" ,[etc...] " & _
" FROM [{{connString}}].[{{sheetName}}$G2:M{{lastRow}}]"
sqlTransferFromExcel = Replace(sqlTransferFromExcel, "{{lastRow}}", row)
sqlTransferFromExcel = Replace(sqlTransferFromExcel, "{{connString}}", strCon)
sqlTransferFromExcel = Replace(sqlTransferFromExcel, "{{sheetName}}", sht.Name)
CurrentDb.Execute sqlTransferFromExcel
End Sub

Updating records in Access table using excel VBA

UPDATED QUESTION:
I have Update sheet, this sheet contains unique ID that matched the access database ID, I'm trying to update the fields using excel values in "Update" sheet.
The ID is in the Column A the rest of the fields are stored from Column B to R. I'm trying to achieve the below, As follows:
Update the record(values from Column B to R) if Column A (ID) matched existing Access database ID. Then add text in Column S "Updated"
If the Column A (ID) did not found any match in the existing Access database ID, Then add text in Column S "ID NOT FOUND"
Loop to next value
So far, I have the below Sub for Update and Function for Existing ID (Import_Update Module), but I'm getting this error.

My below code is working fine. I tried to address your above three points in a different way.
##########################
IMPORTANT
1) I have removed your other validations; you can add them back.
2) DB path has been hard coded, you can set it to get from a cells again
3) My DB has only two fields (1) ID and (2) UserName; you will have obtain your other variables and update the UPDATE query.
Below is the code which is working fine to meet your all 3 requests...Let me know how it goes...
Tschüss :)

a = 2
'Define variable for the values from Column B to R. You can always add the direct ceel reference to the SQL also but it will be messy.
'I have used only one filed as UserName and so one variable in column B, you need to keep adding to below and them to the SQL query for othe variables
Dim NewUserName

Error using WorkbookConnection Object to run an Insert Query

I am using VBA to refresh a Data Connection in an Excel workbook with a string variable being used for the Query to run.
When using a SELECT query this all works as it should; if it is an INSERT query, it throws an application-defined or object-defined error on Connections(ConnectionName).Refresh
The error does not repeat itself if I run the code to the point where it adds the Query string into the Data Connection and manually click the Refresh button in Excel.
Sub UploadData()
Dim wb As Workbook
Dim UploadSheetNum As Integer
Dim QueryCol As String
Dim QueryString As String
Dim CurRowString As String
Dim ConnName As String
Set wb = ThisWorkbook
UploadSheetNum = 3
QueryCol = "H"
ConnName = "DataConn"
Call VBAModule_v1.SwitchtoSheet(UploadSheetNum, wb)
For i = 1 To VBAModule_v1.GetLastRow(QueryCol)
CurRowString = wb.Sheets(UploadSheetNum).Range(QueryCol & i)
QueryString = QueryString & CurRowString & Chr(10)
Next i
Call VBAModule.RefreshConnection(ConnName, QueryString, wb)
End Sub
Sub RefreshConnection(ConnectionName As String, Query As String, wb As Workbook)
wb.Activate
On Error GoTo ExitProc
With wb.Connections(ConnectionName).ODBCConnection
.BackgroundQuery = False
.CommandText = Query
End With
wb.Connections(ConnectionName).Refresh
DoEvents
Exit Sub
ExitProc:
MsgBox ("Error Sub RefreshConnection: Issue with ConnectionName '" & _
ConnectionName & "' or Query - " & Err.Description)
End Sub
Actually just tripped over the answer. So, WorkbookConnection Object works for queries that return a result e.g Select queries, but not so much for queries that don't e.g. Insert, Update, Deletes.
The below subroutine will run an Insert query without error:
Sub RunInsertQuery(InsertTable As String, InsertValues As String)
On Error GoTo ExitProc
Dim Dataconn As Object
Set Dataconn = CreateObject("ADODB.Connection")
connstr = "DRIVER={'SQL DRIVER To Use'};" & _
"SERVER='SERVERNAME to Connect to';" & _
"PORT='PortNumber'" & _
"DATABASE='Database Name';" & _
"UID='User Id to use';" & _
"PWD='User Password';"
Dataconn.Open connstr
Dataconn.Execute "INSERT INTO " & InsertTable & " VALUES " & InsertValues
Dataconn.Close
Set Dataconn = Nothing
Exit Sub
ExitProc:
MsgBox ("Error Sub RunInsertQuery: Issue with Tablename for Insert '" & InsertTable & "' or Values being Inserted - " & Err.Description)
End Sub

Rearranging columns in VBA

The current codes I am working on requires me to rearrange the columns in VBA. It has to arranged according to the header, and the headers are "V-d(1)", "V-g(1)", "I-d(1)", "I-g(1)", and this set repeats for numbers 2, 3, etc etc. (e.g V-d(2), I-g(4)). These data are usually jumbled up and I have to arrange them in ascending numbers.
It does not matter if V-g, V-d, I-d or I-g comes first.
Dim num, numadj As Integer
Dim colu, coladj
Range("A1").Select
Do While Range("A1").Offset(0, i - 1).Value <> ""
colu = ActiveCell.Value
coladj = ActiveCell.Offset(0, 1).Value
num = Left(Right(colu.Text, 2), 1)
numadj = Left(Right(coladj.Text, 2), 1)
If num > numadj Then
colu.EntireColumn.Cut Destination:=Columns("Z:Z")
coladj.EntireColumn.Cut Destination:=colu
Columns("Z:Z").Select.Cut Destination:=coladj
i = i + 1
Else
i = i + 1
End If
Loop
I am very new to VBA so please forgive me for any dumb codes that I have created!!! Thank you in advance everyone!
Consider an SQL and RegEx solution to select columns in a specified arrangement. SQL works in Excel for PC which can access Windows' Jet/ACE SQL Engine to query its own workbook like a database table.
Due to the variable nature of sets ranging 3-10, consider finding the highest number set by extracting the numbers from column headers with RegEx using the defined function, FindHighestNumberSet. Then have RunSQL subroutine call the function to build SQL string dynamically.
Below assumes you have data currently in a tab named DATA with an empty tab named RESULTS which will output query results. Two ADO connection strings are available.
Function (iterating across column headers to extract highest number)
Function FindHighestNumberSet() As Integer
Dim lastcol As Integer, i As Integer
Dim num As Integer: num = 0
Dim regEx As Object
' CONFIGURE REGEX OBJECT
Set regEx = CreateObject("VBScript.RegExp")
With regEx
.Global = True
.MultiLine = True
.IgnoreCase = False
.Pattern = "[^0-9]"
End With
With Worksheets("DATA")
lastcol = .Cells(7, .Columns.Count).End(xlToLeft).Column
For i = 1 To lastcol
' EXTRACT NUMBERS FROM COLUMN HEADERS
num = Application.WorksheetFunction.Max(num, CInt(regEx.Replace(.Cells(1, i), "")))
Next i
End With
FindHighestNumberSet = num
End Function

You can sort vertically by a helper row with something like this (tested):
Sub test() ': Cells.Delete: [b2:d8] = Split("V-d(10) V-d(2) V-d(1)") ' used for testing
Dim r As Range: Set r = ThisWorkbook.Worksheets("Sheet1").UsedRange ' specify the range to be sorted here
r.Rows(2).Insert xlShiftDown ' insert helper row to sort by. (used 2nd row instead 1st so that it is auto included in the range)
r.Rows(2).FormulaR1C1 = "=-RIGHT(R[-1]C,LEN(R[-1]C)-3)" ' to get the numbers from the column header cells above, so adjust if needed
r.Sort r.Rows(2) ' sort vertically by the helper row
r.Rows(2).Delete xlShiftUp ' delete the temp row

Reading data from Access to Excel GetMDB() macro works fine, But when I tried to update the data from Excel to Access, code gives me following error:
Run-time error '3021':
Either BOF or EOF is True, or the current record has been deleted.
Requested operation requires a current record.
I checked the mdb, xlsx and sheet path and names are correct. Anyone got a similar problem as well and how to overcome? Thanks.
You cannot run UPDATE queries using Excel workbook sources as any SQL queries using workbooks are read-only from last saved instance and cannot be updated. Excel simply is not a database to do such transactions with no record-level locking mechanism, read/write access, or relational model. Though you can run append (INSERT INTO ... SELECT *) and make-table queries (SELECT * INTO FROM ...), you cannot run UPDATE that aligns to live values.
However, you can read in an Access recordset and iterate through the Excel cells aligning by ID matches. Below assumes the Excel Sheet's ID column is in Column A and Field1 is in Column B.
Dim accConn As Object, accRST As Object
Dim accFile As String, accStr As String
Dim lastrow As Long, i As Long
Const adOpenKeyset = 1, adLockOptimistic = 3, adCmdTableDirect = 512
lastrow = Workbooks(1).Sheets(1).Cells(Workbooks(1).Sheets(1).Rows.Count, "A").End(xlUp).Row
accFile = "Z:\Documents\Database\Database1.mdb"
accStr = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & accFile & ";"
Set accConn = CreateObject("ADODB.Connection")
Set accRST = CreateObject("ADODB.Recordset")
accConn.Open accStr
accRST.Open "SELECT * FROM Table1", accConn, adOpenKeyset, adLockOptimistic, adCmdTableDirect
If Not (accRST.BOF And accRST.EOF) Then
accRST.MoveFirst
Else
Msgbox "No records in Access table.", vbInformation
accRST.Close: accConn.Close: Set accRST = Nothing: Set accConn = Nothing
Exit Sub
End If
Do While Not accRST.EOF
For i = 1 to lastrow
If accRST!ID = Workbooks(1).Sheets(1).Range("A" & i) _
And accRST!Field1 <> Workbooks(1).Sheets(1).Range("B" & i) Then
accRST!Field1.Value = Workbooks(1).Sheets(1).Range("B" & i)
End If
Next i
accRST.Update
accRST.MoveNext
Loop
accRST.Close: accConn.Close
Set accRST = Nothing: Set accConn = Nothing
Notes:
If IDs between Excel worksheet and Access table are not one-to-one (i.e., Excel has multiple rows of same ID), the last Field1 value following the If logic will be inserted to corresponding Access row.
Above may be extensive processing if database rows and Excel cells are large. The best option is simply to use Access for all data entry/management and avoid the update needs. Since Excel is a flatfile, consider using it as the end use application and Access as central data repository.

Linking Excel Tables in Access Gives Read-Only Error

I have a couple of Excel 2010 files that are mapped and linked to an Access 2010 database. I need to add another file so that three are mapped instead of two. I linked the excel file from the Import and Link tab under External Database. That seems to be okay. But when I run the code that re-maps the excel file, it gives me a runtime error 3027: Database or Object is read only. None of the files or database are read-only.
This is the code to re-map the files from a new location (ex. from the X-drive to the mail W-drive), which would also add the new excel file. Should something be added here to let me add new files?
Private Sub cmdAcceptPath_Click()
Dim db As DAO.Database
Dim rs As DAO.Recordset
Dim strSQL As String
Dim strPath As String
Dim strFileName As String
Dim strSourceDB As String
Dim strTableName As String
Dim sList As String
Dim gMsgBoxTitle As String
On Error GoTo Error_Handler:
DoCmd.SetWarnings False
strSourceDB = Me.tExcelPath.Value
Set db = CurrentDb
strSQL = "update tblBackendFiles set setting=" & setData(strSourceDB) & " where code='SourceExcel'"
DoCmd.RunSQL strSQL
'-- Verify linked tables by refreshing
strSQL = "select setting, ExcelPath, ExcelRange from tblBackendFiles where code='SourceExcelWB'"
Set rs = db.OpenRecordset(strSQL, dbOpenDynaset)
'Open remapprogress
DoCmd.OpenForm "frmReMapProgress"
sList = ""
rs.MoveFirst
While Not rs.EOF
strTableName = rs!Setting
sList = sList & vbNewLine & "Deleting Table: " & strTableName
Forms!frmReMapProgress.tbProgress = sList
If TableExists(strTableName) Then
DoCmd.DeleteObject acTable, strTableName
End If
rs.MoveNext
Wend
sList = ""
'-- Relink inventory database
rs.MoveFirst
While Not rs.EOF
sList = sList & vbNewLine & "Linking Table: " & strTableName
Forms!frmReMapProgress.tbProgress = sList
Forms!frmReMapProgress.Refresh
strTableName = rs!Setting
strPath = strSourceDB & "\" & rs!ExcelPath
Debug.Print strPath
DoCmd.TransferSpreadsheet acLink, acSpreadsheetTypeExcel9, strTableName, strPath, True, rs!ExcelRange
rs.MoveNext
Wend
rs.Close
MsgBox "Re-Mapping Excel Links is Complete!"
GoTo exit_sub:
'If error occurs
Error_Handler:
MsgBox Err.number & ": " & Err.Description, vbInformation + vbOKOnly, gMsgBoxTitle
exit_sub:
Set db = Nothing
Set rs = Nothing
DoCmd.SetWarnings True
DoCmd.Close acForm, "frmReMapProgress"
DoCmd.Close acForm, "frmReMapExcel"
End Sub
You don't need to delete and recreate the link to the Excel file. Just close the linked table (if open) and replace the Excel file with the new copy.
When you open the linked table, it will read from the new file.
