Question

I have been over my code numerous times and hope someone can help me see something I don’t. I’m trying to pull data from Excel into a SQL table with multiple columns in VS2010 but when I try uploading the data, I get the error “Cannot Find Column 8.” I see nothing wrong with column 8 nor any of the other columns. Anyone else? Thanks!

protected void Button1_Click(object sender, EventArgs e)
{
    //make local copy
    string sheetname = "Sheet1";
    string path = Server.MapPath("~/Import.xls");
    //connect to local Excel
    try
    {

        FileUpload.SaveAs(path);
        System.Data.OleDb.OleDbConnection MyConnection;
        System.Data.DataSet DtSet;
        System.Data.OleDb.OleDbDataAdapter MyCommand;  //check sheet name
        MyConnection = new System.Data.OleDb.OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + path + ";Extended Properties=Excel 12.0;");
        MyCommand = new System.Data.OleDb.OleDbDataAdapter("select * from [" + sheetname + "$]", MyConnection);
        MyCommand.TableMappings.Add("Table", "TestTable");
        DtSet = new System.Data.DataSet();
        MyCommand.Fill(DtSet);
        SqlConnection curConnection = new SqlConnection(@"Data Source=1tc-Techcomm2;Initial Catalog=EventManagement;Integrated Security=True");
        curConnection.Open();
        SqlCommand curCommand;
        SqlParameter param;
        string str;

        for (int i = 0; i < DtSet.Tables[0].Rows.Count; i++)
        {
            if (DtSet.Tables[0].Rows[i][1] == DBNull.Value)
                continue;
            curCommand = curConnection.CreateCommand();
            curCommand.CommandText = @"Insert into TestSP (SessionHead_Title, SessionHead_Type, SessionHead_Description, SessionHead_Confirmed, SessionHead_Presenter, SessionHead_Champion, SessionHead_Objective, SessionHead_Notes, SessionHead_Schedule, SessionHead_Equipment, SessionHead_Hardware, SessionHead_CDA) Values (@a,@b,@c,@d,@e,@f,@g,@h,@i,@j,@k,@l,@m)";
            for (int j = 0; j < 13; j++)
            {
                param = new SqlParameter();
                str = "@";
                str += (char)('a' + j);
                param.ParameterName = str;
                param.SqlDbType = SqlDbType.VarChar;
                param.Value = DtSet.Tables[0].Rows[i][j];//This is where it errors out at after 8 times through
                curCommand.Parameters.Add(param);

            }
            Label1.Text = "THE EXCEL DATE HAS SUCCESSFULLY BEEN SENT TO THE DATABASE"; 

            int Event_Id = curCommand.ExecuteNonQuery();

        }
        MyConnection.Close();
        curConnection.Close();
    }
    catch (Exception ex)
    {
        //Response.Write(ex.ToString());
        Label1.Text = ex.Message; 

    }
}

I believe the issue was that the spreadsheet column headers did not match the table headers. I read somewhere that the Column names in SQL Server table must be the same in the Excel file. I guess this solves it…thanks for the help!
