Saving Results of Access Query To Worksheet Excel VBA - vba

I cant seem to find an easy way of doing outside of just accessing the SQL from ACCESS SQL View and doing it manually. Is there some magic way to use this code below and do that?
Its worth pointing out that I am trying to do this from Excel's VBA.
Private Sub tryagain()
Dim con As ADODB.Connection
Dim rs As ADODB.Recordset
Set con = New ADODB.Connection
With con
.Provider = "Microsoft.ACE.OLEDB.12.0"
.Open "C:\Users\Ashleysaurus\Desktop" & "\" & "xyzmanu3.accdb"
End With
con.Execute "Invoice Query"
'How do output to Worksheet?
rs.Close
cmd.ActiveConnection.Close
End Sub

Simply use the ADO recordset object which you initialize, call the query, and then run the Range.CopyFromRecordset method (specifying the leftmost worksheet cell to place results).
Also, see the changed connection open routine with proper connection string. And because recordsets do not pull in column headers automatically but only data, an added loop was included iterating through recordset's field names.
Private Sub tryagain()
Dim con As New ADODB.Connection
Dim rs As New ADODB.Recordset
Dim strConnection As String
Dim i as Integer, fld As Object
strConnection = "Provider=Microsoft.ACE.OLEDB.12.0;" _
& "Data Source='C:\Users\Ashleysaurus\Desktop\xyzmanu3.accdb';"
con.Open strConnection
rs.Open "SELECT * FROM [Invoice Query]", con
' column headers
i = 0
Sheets(1).Range("A1").Activate
For Each fld In rs.Fields
ActiveCell.Offset(0, i) = fld.Name
i = i + 1
Next fld
' data rows
Sheets(1).Range("A2").CopyFromRecordset rs
rs.Close
cn.Close
End Sub
By the way, this same above setup can even query Excel workbooks as the Jet/ACE SQL Engine is a Windows technology (.dll files) available to all Office or Windows programs.
strConnection = "Provider=Microsoft.ACE.OLEDB.12.0;" _
& "Data Source='C:\Path\To\Workbook.xlsm';" _
& "Extended Properties=""Excel 8.0;HDR=YES;"";"
strSQL = "SELECT * FROM [Sheet1$]"

VBA, Import CSV split by ";" to sheet

I am trying to import a CSV file split by semicolon ";" into an excel object so I can use it later on.
Ideally i would like to use ADO, DAO or ADODB so I can also run SQL queries on the object, and get sum of specific fields, or total number of fields and so on.
So far i've gotten the code below, but it does not split the data by ";", so it all comes back as 1 field instead of multiple fields that can be handled.
Sub Import()
Dim conn As New ADODB.Connection
Dim rs As New ADODB.Recordset
Dim f As ADODB.Field
Dim csvName, csvPath
csvPath = ActiveWorkbook.path
csvName = "fileName.csv"
conn.Open "DRIVER={Microsoft Text Driver (*.txt; *.csv)};DBQ=" & csvPath & ";"
rs.Open "SELECT * FROM " & csvName, conn, adOpenStatic, adLockReadOnly, adCmdText
Debug.Print rs.Fields
While Not rs.EOF
For Each f In rs.Fields
Debug.Print f.Name & "=" & f.Value
Next
Wend
End Sub
Can anyone give me an idea how I can also split the data by ";" and query it using SQL query? Or a different object that I could load a CSV into and query certain columns.
Here's example:
Public Sub QueryTextFile()
Dim rsData As ADODB.Recordset
Dim sConnect As String
Dim sSQL As String
' Create the connection string.
sConnect = "Provider=Microsoft.ACE.OLEDB.12.0;" & _
"Data Source=C:\Files\;" & _
"Extended Properties=Text;"
' Create the SQL statement.
sSQL = "SELECT * FROM Sales.csv;"
Set rsData = New ADODB.Recordset
rsData.Open sSQL, sConnect, adOpenForwardOnly, _
adLockReadOnly, adCmdText
' Check to make sure we received data.
If Not rsData.EOF Then
' Dump the returned data onto Sheet1.
Sheet1.Range("A1").CopyFromRecordset rsData
Else
MsgBox "No records returned.", vbCritical
End If
' Clean up our Recordset object.
rsData.Close
Set rsData = Nothing
End Sub
The only answer I found that was usable was to create an ini file in the current folder, and enter the delimiter in the ini file.
iniPath = activeworkbook.path & "\"
iniName = "schema.ini"
iniPathName = iniPath & iniName
If Not fso.FileExists(iniPathName) Then
fso.CreateTextFile (iniPathName)
End if

Query range in activeworkbook using ADODB

I'm trying to write some VBA that can query a named range in VBA using SQL. Currently, it works reasonably well, but i have the problem that every time i run the macro a read-only instance of the worksheet is opened. I want to use the macro to query ranges within the same workbook without opening a read-only copy.
Here is my code
Public Sub QueryAndOutputToCell(ByVal query As String, rng As Range)
Dim conn As ADODB.Connection
Set conn = New ADODB.Connection
Dim DBFullName, connString, SQL As String
DBFullName = ThisWorkbook.path & "\" & ThisWorkbook.name
connString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source='" & DBFullName & "';Extended Properties='Excel 12.0;HDR=Yes;IMEX=1';"
conn.connectionString = connString
conn.Open ' Read-only copy is opened here
conn.commandtimeout = 0
Dim cubeData As ADODB.Recordset
Set cubeData = New ADODB.Recordset
cubeData.Open query, conn, adOpenDynamic, adLockReadOnly
rng.CopyFromRecordset cubeData
cubeData.Close
conn.Close
Set cubeData = Nothing
Set conn = Nothing
End Sub
Do anyone know if this is possible?

Copying ADO recordset into excel worksheet

I'm trying to open a CSV file and query it and return the results into column A of the second worksheet of "ThisWorkbook".
I'm not getting any errors so I do not see why it is not copying the record set into excel.
Dim con As ADODB.Connection
Dim rs As ADODB.Recordset
Set con = New ADODB.Connection
Set rs = New ADODB.Recordset
Dim currentDataFilePath As String
Dim currentDataFileName As String
Dim nextRow As Integer
currentDataFilePath = "C:\Users\M\folder\"
currentDataFileName = "csv-file"
con.Open "Provider=Microsoft.JET.OLEDB.4.0;" & _
"Data Source=" & currentDataFilePath & ";" & _
"Extended Properties=""text;HDR=NO;FMT=Delimited;IMEX=1"""
'rs.ActiveConnection = con
rs.Open "SELECT Name FROM [" & currentDataFileName & ".csv] WHERE Datatype ='TYPE3'",
con
ThisWorkbook.Worksheets("Sheet2").Range("A:A").CopyFromRecordset rs
rs.Close
con.Close
Set rs = Nothing
Set con = Nothing
End Sub
You might refer to the CopyFromRecordset() method.
Based on your code above, after the rs.Open command you would add something like this:
ActiveWorksheet.Range("A1").CopyFromRecordset rs

Update Excel data via SQL UPDATE

I'd like to update my Excel sheet's data via an SQL query. I know you can 'connect' to a sheet via ADODB.Connection and retrieve (SELECT) data from it in a ADODB.Recordset. However using the same process for an UPDATE query produces an 'Operation must use an updateable query' error. Is there any other way to achieve this?
An example code that produces the error:
Sub SQLUpdateExample()
Dim con As ADODB.Connection
Dim rs As ADODB.Recordset
Set con = New ADODB.Connection
con.Open "Driver={Microsoft Excel Driver (*.xls)};" & _
"DriverId=790;" & _
"Dbq=" & ThisWorkbook.FullName & ";" & _
"DefaultDir=" & ThisWorkbook.FullName
Set rs = New ADODB.Recordset
Set rs = con.Execute("UPDATE [Sheet1$] SET a = 10 WHERE b > 2")
Set rs = Nothing
Set con = Nothing
End Sub
The code expects to be in a saved .xls worksheet where Sheet1 includes a table with column headers (at least) a and b.
Didn't think that would be all to make it work...

Connections to Excel files are set to ReadOnly as default.
You have to add ReadOnly=False to your Connection String.

Query Excel worksheet in MS-Access VBA (using ADODB recordset)

I'd like to query an Excel worksheet in VBA and specify conditions.
The simple query "SELECT * FROM [PCR$]" works perfectly, but I don't know how to add a WHERE clause.
I tried cmd2.CommandText = "SELECT * FROM [PCR$] WHERE ([B1] IS NOT NULL)" but then it complains about missing parameters.
This is the complete code:
Dim rs2 As New ADODB.Recordset
Dim cnn2 As New ADODB.Connection
Dim cmd2 As New ADODB.Command
Dim intField As Integer
Dim strFile As String
strFile = fncOpenFile
If strFile = "" Then Exit Sub
With cnn2
.Provider = "Microsoft.Jet.OLEDB.4.0"
.ConnectionString = "Data Source='" & strFile & "'; " & "Extended Properties='Excel 8.0;HDR=Yes;IMEX=1'"
.Open
End With
Set cmd2.ActiveConnection = cnn2
cmd2.CommandType = adCmdText
cmd2.CommandText = "SELECT * FROM [PCR$]"
rs2.CursorLocation = adUseClient
rs2.CursorType = adOpenDynamic
rs2.LockType = adLockOptimistic
rs2.Open cmd2
In your connection string you say
Excel 8.0;HDR=Yes
Which means that the first row will be treated as the header, no matter what it contains. If you want to use F1, F2 etc, say
Excel 8.0;HDR=No
Because you have the HDR=Yes option, the column name should be the data in the first row.
