SQL upload XLS file to a SQL table

The following Visual Basic 6.0 code sample requires that you add a project reference to ADO. This code sample demonstrates how to import Excel data to SQL Server over an ADO connection by using the Jet 4.0 Provider.
 
    Dim cn As ADODB.Connection
    Dim strSQL As String
    Dim lngRecsAff As Long
    Set cn = New ADODB.Connection
    cn.Open "Provider=Microsoft.Jet.OLEDB.4.0;" & _
        "Data Source=C:\test\xltestt.xls;" & _
        "Extended Properties=Excel 8.0"
    
    'Import by using Jet Provider.
    strSQL = "SELECT * INTO [odbc;Driver={SQL Server};" & _
        "Server=<server>;Database=<database>;" & _
        "UID=<user>;PWD=<password>].XLImport9 " & _
        "FROM [Customers$]"
    Debug.Print strSQL
    cn.Execute strSQL, lngRecsAff, adExecuteNoRecords
    Debug.Print "Records affected: " & lngRecsAff
        
    cn.Close
    Set cn = Nothing
                

Use ADO and SQLOLEDB
When you are connected to SQL Server in an ADO application by using Microsoft OLE DB for SQL Server (SQLOLEDB), you can use the same "distributed query" syntax from the Using Distributed Queries section to import Excel data into SQL Server.
 
The following Visual Basic 6.0 code sample requires that you add a project reference to ActiveX Data Objects (ADO). This code sample also demonstrates how to use OPENDATASOURCE and OPENROWSET over an SQLOLEDB connection.
 
    Dim cn As ADODB.Connection
    Dim strSQL As String
    Dim lngRecsAff As Long
    Set cn = New ADODB.Connection
    cn.Open "Provider=SQLOLEDB;Data Source=<server>;" & _
        "Initial Catalog=<database>;User ID=<user>;Password=<password>"
 
    'Import by using OPENDATASOURCE.
    strSQL = "SELECT * INTO XLImport6 FROM " & _
        "OPENDATASOURCE('Microsoft.Jet.OLEDB.4.0', " & _
        "'Data Source=C:\test\xltest.xls;" & _
        "Extended Properties=Excel 8.0')...[Customers$]"
    Debug.Print strSQL
    cn.Execute strSQL, lngRecsAff, adExecuteNoRecords
    Debug.Print "Records affected: " & lngRecsAff
 
    'Import by using OPENROWSET and object name.
    strSQL = "SELECT * INTO XLImport7 FROM " & _
        "OPENROWSET('Microsoft.Jet.OLEDB.4.0', " & _
        "'Excel 8.0;Database=C:\test\xltest.xls', " & _
        "[Customers$])"
    Debug.Print strSQL
    cn.Execute strSQL, lngRecsAff, adExecuteNoRecords
    Debug.Print "Records affected: " & lngRecsAff
 
    'Import by using OPENROWSET and SELECT query.
    strSQL = "SELECT * INTO XLImport8 FROM " & _
        "OPENROWSET('Microsoft.Jet.OLEDB.4.0', " & _
        "'Excel 8.0;Database=C:\test\xltest.xls', " & _
        "'SELECT * FROM [Customers$]')"
    Debug.Print strSQL
    cn.Execute strSQL, lngRecsAff, adExecuteNoRecords
    Debug.Print "Records affected: " & lngRecsAff
 
    cn.Close
    Set cn = Nothing
