Eksportowanie SQL do Excela

Question

Jak mogę eksportować moje dane z SQL Server 2008 do Excel 2010 lub późniejszych?

Próbowałem na SQL sposób:

sp_configure 'show advanced options', 0; 
GO 
RECONFIGURE; 
GO 
sp_configure 'Ad Hoc Distributed Queries', 0; 
GO 
RECONFIGURE; 
GO 
INSERT INTO OPENROWSET('Microsoft.Jet.OLEDB.4.0', 
'Excel 8.0;Database=C:\testing.xls;Extended Properties=EXCEL 12.0;HDR=YES', 
'SELECT NO_ORDRE, Date FROM [Sheet1$]') 
SELECT [NO_ORDRE], GETDATE() FROM ORDRE 
GO 

unfortuntely i pojawia się błąd: OLE DB provider 'Microsoft.Jet.OLEDB.4.0' nie może być stosowany dla rozproszonych zapytań, ponieważ dostawca jest skonfigurowany do uruchomić w trybie STA.

a następnie próbowałem na C# sposób:

public class ExportToExcel 
    { 
     private Excel.Application app; 

     private Excel.Workbook workbook; 
     private Excel.Worksheet previousWorksheet; 
     // private Excel.Range workSheet_range; 
     private string folder; 

     public ExportToExcel(string folder) 
     { 

      this.folder = folder; 
      this.app = null; 
      this.workbook = null; 
      this.previousWorksheet = null; 
      // this.workSheet_range = null; 

      createDoc(); 
     } 

     private void createDoc() 
     { 
      try 
      { 
       app = new Excel.Application(); 
       app.Visible = false; 
       workbook = app.Workbooks.Add(1); 
      } 
      catch (Exception excThrown)

       throw new Exception(excThrown.Message); 
      }

niestety dostałem błąd: Pobieranie fabryki klasy COM dla składnika z CLSID {00024500-0000-0000-C000-000000000046} nie powiodło się ze względu na następujące error: 80070005 Odmowa dostępu. (Wyjątek od HRESULT: 0x80070005 (E_ACCESSDENIED)).

Każdy pomysł jak eksportować SQL do Excela?

Answer 1

Najlepszym rozwiązaniem może być napisanie go do pliku CSV. Excel rejestruje się jako plik obsługi plików CSV, więc domyślnie otworzy się w programie Excel.

Na przykład:

private void SQLToCSV(string query, string Filename) 
{ 

    SqlConnection conn = new SqlConnection(connection); 
    conn.Open(); 
    SqlCommand cmd = new SqlCommand(query, conn); 
    SqlDataReader dr = cmd.ExecuteReader(); 

    using (System.IO.StreamWriter fs = new System.IO.StreamWriter(Filename)) 
    { 
     // Loop through the fields and add headers 
     for (int i = 0; i < dr.FieldCount; i++) 
     { 
      string name = dr.GetName(i); 
      if (name.Contains(",")) 
       name = "\"" + name + "\""; 

      fs.Write(name + ","); 
     } 
     fs.WriteLine(); 

     // Loop through the rows and output the data 
     while (dr.Read()) 
     { 
      for (int i = 0; i < dr.FieldCount; i++) 
      { 
       string value = dr[i].ToString(); 
       if (value.Contains(",")) 
        value = "\"" + value + "\""; 

       fs.Write(value + ","); 
      } 
      fs.WriteLine(); 
     } 

     fs.Close(); 
    } 
} 

Answer 2

powiązać dane w widoku siatki .... i wykorzystać następujący kod .....

protected void ImageButton1_Click1(object sender, ImageClickEventArgs e) 
{ 

    string attachment = "attachment; filename=Contacts.xls"; 
    Response.ClearContent(); 

    Response.AddHeader("content-disposition", attachment); 
    Response.ContentType = "application/ms-excel"; 

    StringWriter sw = new StringWriter();HtmlTextWriter htw = new HtmlTextWriter(sw); 
    GridView2.RenderControl(htw); 

    Response.Write(sw.ToString()); 

    Response.End(); 

} 

Answer 3

2 proste opcje byłyby:

1) użyć kreatora importu i eksportu serwera SQL, za pomocą którego można wyeksportować dowolną tabelę z bazy danych w programie Excel (wystarczy upewnić się, że mapowanie jest poprawne)

2) Po prostu uruchom polecenie sql, a następnie w oknie wyników poniżej wybierz wszystkie i kliknij prawym przyciskiem myszy i wykonaj polecenie "Kopiuj z nagłówkami", a następnie wklej wyniki do Excela

Answer 4

Ponieważ używasz Excel 2010 najprostszym rozwiązaniem jest pobranie PowerPivot z Microsoft i wykonanie zapytania SQL bezpośrednio. Spowoduje to utworzenie odświeżającego połączenia danych, które wyciągnie dane z kwerendy do tabeli przestawnej.
