Use ADODB to INSERT INTO specific table in an Excel workbook - excel

I'm trying to use ADODB to execute a SQL INSERT INTO command into an Excel worksheet. I was able to insert into the worksheet when there was only one column in the worksheet using this code:
Const adOpenStatic = 3
Const adLockOptimistic = 3
Const adCmdText = &H1
Dim Connection As ADODB.Connection
Set Connection = New ADODB.Connection
Connection.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data
Source=PathToFile.xls;Extended
Properties=Excel 8.0;"
Connection.Open
Dim SQL As String
SQL = "INSERT INTO [Sheet1$] VALUES('Test')"
Call Connection.Execute(SQL, , CommandTypeEnum.adCmdText Or ExecuteOptionEnum.adExecuteNoRecords)
But I want to have three separate tables in the same worksheet and specify which of the tables to insert into. How can I do this? I tried creating the tables, naming them, and using this SQL statement to specify a table but I kept getting the error: The Microsoft Jet database engine could not find the object 'TestTable1'. Make sure the object exists and that you spell its name and the path name correctly.
SQL = "INSERT INTO TestTable1(ID) VALUES('test')"

You can do something like this:
Sub TestInsert()
InsertRecords Sheet4.Range("B3").CurrentRegion, _
"insert into # values('AAA','BBB','CCC')"
InsertRecords Sheet4.Range("F3").CurrentRegion, _
"insert into # values('ZZZ')"
InsertRecords Sheet4.Range("H3").CurrentRegion, _
"insert into # values('Whirled',99999)"
End Sub
Sub InsertRecords(rng As Range, sSQL As String)
Const S_TEMP_TABLENAME As String = "SQLtempTable"
Dim oConn As New ADODB.Connection
Dim sPath
'name the selected range
On Error Resume Next
ThisWorkbook.Names.Item(S_TEMP_TABLENAME).Delete
If Err.Number <> 0 Then Err.Clear
On Error GoTo haveError
ThisWorkbook.Names.Add Name:=S_TEMP_TABLENAME, RefersToLocal:=rng
sPath = ThisWorkbook.Path & "\" & ThisWorkbook.Name
oConn.Open "Provider=Microsoft.Jet.OLEDB.4.0;" & _
"Data Source=" & sPath & _
";Extended Properties=""Excel 8.0;HDR=Yes"""
oConn.Execute Replace(sSQL, "#", S_TEMP_TABLENAME)
Exit Sub
haveError:
MsgBox Err.Description
End Sub

Connectionstring vba with blank space in dataname get broken

My Code is following. I'll try to copy a range of data from a closed sheet with connectionstrings. The Code is okay if the dataname hasn't a empty string.
e.g. test.xlsx is okay but test further.xlsx get broken.
'using sql
Sub ImportThisFile(FilePath As String, SourceSheet As String, Destination As Range)
Set Conn = New ADODB.Connection
'xls
'Conn.Open "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" & _
' FilePath & ";Extended Properties=Excel 8.0;"
'xlsx
Conn.Open "Provider=Microsoft.ACE.OLEDB.12.0; Data Source=" & _
FilePath & ";Extended Properties=Excel 12.0 Xml;"
Sql = "SELECT * FROM [" & SourceSheet & "$] WHERE [fieldname] <> " & [""""""]
Set RcdSet = New ADODB.Recordset
RcdSet.Open Sql, Conn, adOpenForwardOnly
Destination.CopyFromRecordset RcdSet
RcdSet.Close
Set RcdSet = Nothing
Conn.Close
Set Conn = Nothing
End Sub

End Sub
And Second Question.
If I want to copy a range, how i must write the code?
I need to determine the last cell in a column. How is that possible ?
the code i posted is correct. It was a mistake in the workbook (tablename)

Use SQL to Query another excel file

I'm try an alternative to solve this issue using VBA to get the data.
The following code works fine when "Tbltest" is a range but not working when the name represent a table. How can I make it work with Table not range.
Function ConnectToExelPRJReview()
Dim Xlpath As String
On Error GoTo ErrHandlerconnection:
Dim Xlcn As ADODB.Connection
Dim Xlrs As ADODB.Recordset
Xlpath = "\\xxx.xxx.xxxxxx.net\project_review\wip\" & "filetotest.xlsm"
strCon = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & Xlpath _
& ";Extended Properties=""Excel 12.0;HDR=Yes;IMEX=1"";"
Set Xlcn = CreateObject("ADODB.Connection")
Set Xlrs = CreateObject("ADODB.Recordset")
Xlcn.Open strCon
strSQL = "SELECT * FROM [Tbltest]"
Xlrs.Open strSQL, Xlcn
'display the first data
MsgBox Xlrs.Fields(0).Value
Xlcn.Close
Exit Function

Replace Worksheets content without opening it

I am using ADO model to gather data from various closes workbooks. This is working well.
I now want to put this data in another closed workbook, but I would like to be able to delete a sheet content before.
How can I delete a worksheet content without opening the workbook using VBA ?
How can I transfer a record set to a closed wb ? / Copy one table to another using ADO ?
EDIT :
I was able to insert some data from one workbook to another one in a new sheet but I can't get to output data in an existing worksheet.
When I try the INSERT INTO statement, an error is raised. Update impossible, database or object readonly.
Here is the code :
Sub tranfert()
Dim ExcelCn As ADODB.Connection
Dim ExcelRst As ADODB.Recordset
Dim Cn As New ADODB.Connection
Dim Rst As New ADODB.Recordset
Dim maBase As String, maFeuille As String
Dim maTable As String, NomClasseur As String
Dim nbEnr As Long
maBase = "C:\Users\Lichar\Documents\Base.xlsx"
maTable = "[table$]"
NomClasseur = "C:\Users\Lichar\Documents\Target.xlsx"
maFeuille = "Sheet2"
'Connection to base file
Cn.Open "Provider=Microsoft.ACE.OLEDB.12.0;" & _
"Data Source=" & maBase & ";" & _
"Extended Properties=""Excel 12.0;HDR=NO;"""
'Requète dans la table Access
Rst.Open "SELECT * FROM " & maTable, Cn
'Connection to target file
Set ExcelCn = New ADODB.Connection
ExcelCn.Open "Provider=Microsoft.ACE.OLEDB.12.0;" & _
"Data Source=" & NomClasseur & ";" & _
"Extended Properties=""Excel 12.0;HDR=NO;"""
'-----------------------------------------
'Create a new sheet and output data
Cn.Execute "SELECT * INTO [Excel 12.0;" & _
"Database=" & NomClasseur & "].[" & maFeuille & "] FROM " & maTable, nbEnr
'-----------------------------------------
'Trying to ouput data in existing sheet
'Cn.Execute "INSERT INTO [sheet$] IN '' [Excel 12.0;" & _
' "Database='" & NomClasseur & "'] SELECT * FROM " & maTable, nbEnr
Rst.Close
Cn.Close
Set ExcelRst = Nothing
Set ExcelCn = Nothing
**EDIT 2 **
I've found a partial solution using INSERT INTO. Here is a working code that takes data from source.xlsx in the table sheet and output it (or append) in target.xlsx in the sheet sheet :
Sub SQLQUERY()
Dim Cn As ADODB.Connection
Dim QUERY_SQL As String
Dim Rst As ADODB.Recordset
Dim ExcelCn As ADODB.Connection
Dim ExcelRst As ADODB.Recordset
SourcePath = "C:\Users\BVR\Documents\Source.xlsx"
TargetPath = "C:\Users\BVR\Documents\Target.xlsx"
CHAINE_HDR = "[Excel 12.0 MACRO;Provider=Microsoft.ACE.OLEDB.12.0;Mode=Read;Extended Properties='HDR=YES;'] "
Set Cn = New ADODB.Connection
STRCONNECTION = _
"Provider=Microsoft.ACE.OLEDB.12.0;" & _
"Data Source='" & SourcePath & "';" & _
"Mode=Read;" & _
"Extended Properties=""Excel 12.0 Macro;"";"
QUERY_SQL = _
"SELECT * FROM [table$] "
Cn.Open STRCONNECTION
Set ExcelCn = New ADODB.Connection
ExcelCn.Open "Provider=Microsoft.ACE.OLEDB.12.0;" & _
"Data Source=" & TargetPath & ";" & _
"Extended Properties=""Excel 12.0;HDR=NO;"""
Cn.Execute "INSERT INTO [sheet$] IN '" & TargetPath & "' 'Excel 12.0;' " & QUERY_SQL
'--- Fermeture connexion ---
Cn.Close
End Sub
I've noticed 2 problems. First If one of my field name contains a "." in it, the code will generate an error stating that INSERT INTO contains an unknown field name. This is problematic.
Second I cannot select only the columns I want. If I "SELECT [F1], [F2] ..." an error will raise stating that there is a circular reference. (I can however select the columns I want using field names)

Using 'Insert Into' SQL Statement with column names on Excel Worksheet with ACE OLEDB fails

So, I want to get disciplined in how I store data to worksheets and was wanting to use the SQL OLEDB Provide for Excel and standard SQL statements. Insert into with column names does not work, yet, for me at least. Some code demonstrates the problem. Expecting both forms shown here to work W3 Schools SQL INSERT INTO Statement

It seems one adds square brackets around the column names

Reading Data using OLEDB from opened Excel File

I have an excel file(Lets' say File X) with 2 sheets. In first sheet I display charts. Second I have data for the chart. In order to get data from chart, I need to process that data as we do in SQL like Group by, order by. Is there any way I can use oledb to read data from second sheet using VBA code in same excel file(file X)?
Thanks!!
Here's an example of using SQL to join data from two ranges: it will work fine if the file is open (as long as it has been saved, because you need a file path).
Sub SqlJoin()
Dim oConn As New ADODB.Connection
Dim oRS As New ADODB.Recordset
Dim sPath
Dim sSQL As String
sSQL = "select a.blah from <t1> a, <t2> b where a.blah = b.blah"
sSQL = Replace(sSQL, "<t1>", Rangename(Sheet1.Range("A1:A5")))
sSQL = Replace(sSQL, "<t2>", Rangename(Sheet1.Range("C1:C3")))
If ActiveWorkbook.Path <> "" Then
sPath = ActiveWorkbook.FullName
Else
MsgBox "Workbook being queried must be saved first..."
Exit Sub
End If
oConn.Open "Provider=Microsoft.ACE.OLEDB.12.0;Data Source='" & sPath & "';" & _
"Extended Properties='Excel 12.0;HDR=Yes;IMEX=1';"
oRS.Open sSQL, oConn
If Not oRS.EOF Then
Sheet1.Range("E1").CopyFromRecordset oRS
Else
MsgBox "No records found"
End If
oRS.Close
oConn.Close
End Sub
Function Rangename(r As Range) As String
Rangename = "[" & r.Parent.Name & "$" & _
r.Address(False, False) & "]"
End Function
