Question

I have an Excel Spreadsheet that contains all my data that I need to put into an SQL Server database. I am fairly new o ASP.NET and have never had to export from Excel to SQL Se

Answer 1

I tried exporting data from Excel to SQL server through VBA like this:

Const myDB As String = "tenant"
Const myServer As String = "MPAADM"
Const myDB As String = "new"
Const myServer As String = "arjun"

Sub ExportTableToSQL()

    Dim cn As ADODB.Connection
    Dim cnSQL As ADODB.Connection
    Dim strSQL As String
    Dim lngRecsAff As Long
    Dim sqlTable As String
    Dim acell As Range
    Dim t1 As Date
    Dim t2 As Date
    Dim column As String

    On Error Resume Next
    path = Sheets("Sheet2").Range("B1").Value

    Kill path & \z_temp\aa.xls"
    Kill path & "\z_temp\aa.xls"

    On Error GoTo 0

    On Error GoTo 10
    column = Cells(1, 1).Value

        sqlTable = InputBox("Insert SQL table name")
    Application.Wait (Now + TimeValue("0:00:2"))
    t1 = Now
    Debug.Print t1
    If sqlTable = "" Then Exit Sub
    Application.ScreenUpdating = False
    Set acell = ActiveCell
    If IsEmpty(ActiveCell) Then
        MsgBox "Select a cell inside a table you want to export to SQL"
        Exit Sub
    End If
    ActiveCell.CurrentRegion.Select
    Selection.Copy
    Call NewWorkbook
    Cells(1, 1).Select
    ActiveSheet.Paste

    Set cn = New ADODB.Connection
    Set cnSQL = New ADODB.Connection
    With cnSQL
        .ConnectionString = "provider=sqloledb;Data Source=" & myServer & ";Initial Catalog=" & myDB & ";Trusted_Connection=Yes"
        '      .ConnectionString = "provider=sqloledb;Data Source=" & myServer & ";Initial Catalog=" & myDB & ";Uid=jayantuser;Pwd=Input@123"
        .Open
    End With


    ActiveWorkbook.SaveAs path & "\z_temp\aa.xls"

    cn.Open "Provider=Microsoft.ACE.OLEDB.12.0;" & _
    "Data Source=" & path & "\z_temp\aa.xls;" & _
    "Extended Properties=Excel 12.0"


    strSQL = "drop table " & sqlTable
    Debug.Print strSQL
    On Error Resume Next
    cnSQL.Execute strSQL, lngRecsAff, adExecuteNoRecords
    Err.Clear

        "Server=" & myServer & ";Database=" & myDB & _
        ";trusted_connection=yes]." & sqlTable & _
        " FROM [sheet1$]"

Debug.Print strSQL    
    cn.Execute strSQL, lngRecsAff, adExecuteNoRecords    
    cn.Close
    Set cn = Nothing
    ActiveWorkbook.Close False
    On Error Resume Next
    Kill path & "\z_temp\aa.xlx"
    On Error GoTo 0
    t2 = Now
    Debug.Print t2
    MsgBox sqlTable & " table was successfully imported into SQL Server" & vbNewLine & "Transfered record number: " & lngRecsAff _
