将SQL导出到Excel
我怎样才能将我的数据从SQL Server 2008导出到Excel 2010或更高版本？
我已经尝试过SQL的方式：
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 不幸的是我收到错误：OLE DB提供程序“Microsoft.Jet.OLEDB.4.0”不能用于分布式查询，因为提供程序configuration为在STA模式下运行。
然后我尝试了C＃的方式：
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); } finally { } } public void shutDown() { try { workbook = null; app.Quit(); } catch (Exception excThrown) { throw new Exception(excThrown.Message); } finally { } } public void ExportTable(string query, string sheetName) { SqlDataReader myReader = null; try { using (var connectionWrapper = new Connexion()) { var connectedConnection = connectionWrapper.GetConnected(); Excel.Worksheet worksheet = (Excel.Worksheet)workbook.Sheets.Add(Missing.Value, Missing.Value, 1, Excel.XlSheetType.xlWorksheet); worksheet.Name = sheetName; previousWorksheet = worksheet; SqlCommand myCommand = new SqlCommand(query, connectionWrapper.conn); myReader = myCommand.ExecuteReader(); int columnCount = myReader.FieldCount; for (int n = 0; n < columnCount; n++) { //Console.Write(myReader.GetName(n) + "\t"); createHeaders(worksheet, 1, n + 1, myReader.GetName(n)); } int rowCounter = 2; while (myReader.Read()) { for (int n = 0; n < columnCount; n++) { //Console.WriteLine(); //Console.Write(myReader[myReader.GetName(n)].ToString() + "\t"); addData(worksheet, rowCounter, n + 1, myReader[myReader.GetName(n)].ToString()); } rowCounter++; } } } catch (Exception e) { Console.WriteLine(e.ToString()); } finally { if (myReader != null && !myReader.IsClosed) { myReader.Close(); } myReader = null; } } public void createHeaders(Excel.Worksheet worksheet, int row, int col, string htext) { worksheet.Cells[row, col] = htext; } public void addData(Excel.Worksheet worksheet, int row, int col, string data) { worksheet.Cells[row, col] = data; } public void SaveWorkbook() { String folderPath = "C:\\My Files\\" + this.folder; if (!System.IO.Directory.Exists(folderPath)) { System.IO.Directory.CreateDirectory(folderPath); } string fileNameBase = "db"; String fileName = fileNameBase; string ext = ".xlsx"; int counter = 1; while (System.IO.File.Exists(folderPath + fileName + ext)) { fileName = fileNameBase + counter; counter++; } fileName = fileName + ext; string filePath = folderPath + fileName; try { workbook.SaveAs(filePath, Excel.XlFileFormat.xlWorkbookDefault, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Excel.XlSaveAsAccessMode.xlNoChange, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value); } catch (Exception e) { Console.WriteLine(e.ToString()); } } }
不幸的是我得到错误：检索COM类工厂的组件与CLSID {00024500-0000-0000-C000-000000000046}失败，由于以下错误：80070005访问被拒绝。 （从HRESULTexception：0x80070005（E_ACCESSDENIED））。
任何想法如何可以将SQL导出到Excel？
你最好的select可能是写出来一个CSV。 Excel将自身注册为CSV文件的文件处理程序，因此它将在Excel中默认打开。
例如：
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(); } }
C＃SQL到Excel
从数据库调用SP
public DataTable GetDrugUtilizationReport_IndividualGenerateFile(long pharmacyId, DateTime from, DateTime to, long DrugNameId, int sortBy) { var parameters = new Dictionary<string, object> { { "PharmacyId", pharmacyId }, { "DateFrom", from }, { "DateTo", to }, { "DrugNameId", DrugNameId }, { "SortBy", sortBy } }; return ExecuteQuery("RPT_DrugUtilizationReportByIndividualGenerateFile", CommandType.StoredProcedure, parameters); }
在你的C＃代码中使用
private void OnCreateFileCommand(object obj) { string path, parameterLabel; path = ConfigurationManager.AppSettings["VSSPORTEXELExportPath"]; parameterLabel = FromDate.ToString("yyyy-MM-dd") + "_" + ToDate.ToString("yyyy-MM-dd"); try { path = ExcelUtlity.ExportDataToExcel( dataTable: context.GetDrugUtilizationReport_IndividualGenerateFile(GlobalVar.Pharminfo.pharminfo_PK, FromDate, ToDate, SelectedDrug != null ? SelectedDrug.drugnameid_PK : 0, sortBy: SortBy + 1), directoryPath: path, fileName_withoutExt: "DrugUtilizationReport" + "__" + parameterLabel, skipComplexObjects: true, skipInheritedProps: true); DXMessageBox.Show("Data exported successfully at \"" + path + "\".", GlobalVar.MessageTitle, MessageBoxButton.OK, MessageBoxImage.Information); } catch (Exception ex) { string errorMessage = ExceptionHelper.ProcessException(ex); DXMessageBox.Show(errorMessage, GlobalVar.MessageTitle, MessageBoxButton.OK, MessageBoxImage.Error); } }
Excel实用程序
public static string ExportDataToExcel(DataTable dataTable, string directoryPath, string fileName_withoutExt, bool skipComplexObjects, bool skipInheritedProps, string[] skipProps = null) { if (directoryPath[directoryPath.Length - 1] == '\\') // no need to check for >0 length. let it throw an exection for that directoryPath = directoryPath + "\\"; using (var spreadSheet = new SpreadsheetControl()) { // Create new excel document and import the datatable to the worksheet spreadSheet.CreateNewDocument(); spreadSheet.BeginUpdate(); var worksheet = spreadSheet.Document.Worksheets.ActiveWorksheet; worksheet.Import(source: dataTable, addHeader: true, firstRowIndex: 0, firstColumnIndex: 0); // applying style on header Range range = worksheet.Range["A1:" + worksheet.Columns[worksheet.Columns.LastUsedIndex].Heading+"1"]; Formatting rangeFormatting = range.BeginUpdateFormatting(); rangeFormatting.Fill.BackgroundColor = System.Drawing.Color.LightSteelBlue; rangeFormatting.Font.FontStyle = SpreadsheetFontStyle.Bold; range.AutoFitColumns(); range.EndUpdateFormatting(rangeFormatting); spreadSheet.EndUpdate(); fileName_withoutExt += ".xlsx"; Directory.CreateDirectory(directoryPath); // if directory already exists, CreateDirectory will do nothing spreadSheet.SaveDocument(directoryPath + fileName_withoutExt, DocumentFormat.OpenXml); return directoryPath + fileName_withoutExt; } }
使用Microsoft Office dll
public bool WriteDataTableToExcel(System.Data.DataTable dataTable, string worksheetName, string saveAsLocation, string ReporType) { Microsoft.Office.Interop.Excel.Application excel; Microsoft.Office.Interop.Excel.Workbook excelworkBook; Microsoft.Office.Interop.Excel.Worksheet excelSheet; Microsoft.Office.Interop.Excel.Range excelCellrange; try { // Start Excel and get Application object. excel = new Microsoft.Office.Interop.Excel.Application(); // for making Excel visible excel.Visible = false; excel.DisplayAlerts = false; // Creation a new Workbook excelworkBook = excel.Workbooks.Add(Type.Missing); // Workk sheet excelSheet = (Microsoft.Office.Interop.Excel.Worksheet)excelworkBook.ActiveSheet; excelSheet.Name = worksheetName; excelSheet.Cells[1, 1] = ReporType; excelSheet.Cells[1, 2] = "Date : " + DateTime.Now.ToShortDateString(); // loop through each row and add values to our sheet int rowcount = 2; foreach (DataRow datarow in dataTable.Rows) { rowcount += 1; for (int i = 1; i <= dataTable.Columns.Count; i++) { // on the first iteration we add the column headers if (rowcount == 3) { excelSheet.Cells[2, i] = dataTable.Columns[i - 1].ColumnName; excelSheet.Cells.Font.Color = System.Drawing.Color.Black; } excelSheet.Cells[rowcount, i] = datarow[i - 1].ToString(); //for alternate rows if (rowcount > 3) { if (i == dataTable.Columns.Count) { if (rowcount % 2 == 0) { excelCellrange = excelSheet.Range[excelSheet.Cells[rowcount, 1], excelSheet.Cells[rowcount, dataTable.Columns.Count]]; FormattingExcelCells(excelCellrange, "#CCCCFF", System.Drawing.Color.Black, false); } } } } } // now we resize the columns excelCellrange = excelSheet.Range[excelSheet.Cells[1, 1], excelSheet.Cells[rowcount, dataTable.Columns.Count]]; excelCellrange.EntireColumn.AutoFit(); Microsoft.Office.Interop.Excel.Borders border = excelCellrange.Borders; border.LineStyle = Microsoft.Office.Interop.Excel.XlLineStyle.xlContinuous; border.Weight = 2d; excelCellrange = excelSheet.Range[excelSheet.Cells[1, 1], excelSheet.Cells[2, dataTable.Columns.Count]]; FormattingExcelCells(excelCellrange, "#000099", System.Drawing.Color.White, true); //now save the workbook and exit Excel excelworkBook.SaveAs(saveAsLocation); ; excelworkBook.Close(); excel.Quit(); return true; } catch (Exception ex) { DXMessageBox.Show(ex.Message); return false; } finally { excelSheet = null; excelCellrange = null; excelworkBook = null; } } /// <summary> /// FUNCTION FOR FORMATTING EXCEL CELLS /// </summary> /// <param name="range"></param> /// <param name="HTMLcolorCode"></param> /// <param name="fontColor"></param> /// <param name="IsFontbool"></param> public void FormattingExcelCells(Microsoft.Office.Interop.Excel.Range range, string HTMLcolorCode, System.Drawing.Color fontColor, bool IsFontbool) { range.Interior.Color = System.Drawing.ColorTranslator.FromHtml(HTMLcolorCode); range.Font.Color = System.Drawing.ColorTranslator.ToOle(fontColor); if (IsFontbool == true) { range.Font.Bold = IsFontbool; } }
我修改了上面给出的代码，并正在工作。 根据您的要求编辑
namespace ExcelExport { public class ExportToExcel { string strCon = ConfigurationManager.ConnectionStrings["SafewayGVDemoDBContext"].ConnectionString; private Microsoft.Office.Interop.Excel.Application app; private Microsoft.Office.Interop.Excel.Workbook workbook; private Microsoft.Office.Interop.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 Microsoft.Office.Interop.Excel.Application(); app.Visible = false; workbook = app.Workbooks.Add(1); } catch (Exception excThrown) { throw new Exception(excThrown.Message); } finally { } } public void shutDown() { try { workbook = null; app.Quit(); } catch (Exception excThrown) { throw new Exception(excThrown.Message); } finally { } } public void ExportTable(string procName, string sheetName) { SqlDataReader myReader = null; try { Microsoft.Office.Interop.Excel.Worksheet worksheet = (Microsoft.Office.Interop.Excel.Worksheet)workbook.Sheets.Add(Missing.Value, Missing.Value, 1, Microsoft.Office.Interop.Excel.XlSheetType.xlWorksheet); using (SqlConnection Sqlcon = new SqlConnection(strCon)) { SqlCommand cmd = new SqlCommand(); Sqlcon.Open(); cmd.Connection = Sqlcon; cmd.CommandType = CommandType.StoredProcedure; cmd.CommandText = procName; cmd.Parameters.Add(new SqlParameter("@pvchAction", SqlDbType.VarChar, 50)); cmd.Parameters.Add("@pIntErrDescOut", SqlDbType.Int).Direction = ParameterDirection.Output; cmd.Parameters["@pvchAction"].Value = "select"; worksheet.Name = sheetName; previousWorksheet = worksheet; myReader = cmd.ExecuteReader(); int columnCount = myReader.FieldCount; for (int n = 0; n < columnCount; n++) { //Console.Write(myReader.GetName(n) + "\t"); createHeaders(worksheet, 1, n + 1, myReader.GetName(n)); } int rowCounter = 2; while (myReader.Read()) { for (int n = 0; n < columnCount; n++) { //Console.WriteLine(); //Console.Write(myReader[myReader.GetName(n)].ToString() + "\t"); addData(worksheet, rowCounter, n + 1, myReader[myReader.GetName(n)].ToString()); } rowCounter++; } } } catch (Exception e) { Console.WriteLine(e.ToString()); } finally { if (myReader != null && !myReader.IsClosed) { myReader.Close(); } myReader = null; } } public void createHeaders(Microsoft.Office.Interop.Excel.Worksheet worksheet, int row, int col, string htext) { worksheet.Cells[row, col] = htext; } public void addData(Microsoft.Office.Interop.Excel.Worksheet worksheet, int row, int col, string data) { worksheet.Cells[row, col] = data; } public void SaveWorkbook() { String folderPath = @"C:\My Files\" + this.folder; if (!System.IO.Directory.Exists(folderPath)) { System.IO.Directory.CreateDirectory(folderPath); } string fileNameBase = "db"; String fileName = fileNameBase; string ext = ".xlsx"; int counter = 1; //System.IO.File.Open(folderPath + fileName + ext, System.IO.FileMode.Open); while (System.IO.File.Exists(folderPath + @"\"+ fileName + ext)) { fileName = fileNameBase + counter; counter++; } fileName = fileName + ext; string filePath = folderPath +@"\"+ fileName; try { workbook.SaveAs(filePath, Microsoft.Office.Interop.Excel.XlFileFormat.xlWorkbookDefault, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlNoChange, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value); } catch (Exception e) { Console.WriteLine(e.ToString()); } } }
2个简单的选项将是：
1）使用SQL Server导入和导出向导，您可以使用它导出Excel中的数据库中的任何表（只要确保映射是正确的）
2）只是运行你的sql语句，然后在下面的结果窗口中，select所有，然后右键单击并执行“复制头”，然后将结果粘贴到Excel中
由于您使用Excel 2010，最简单的解决scheme是从Microsoft下载PowerPivot并直接执行SQL查询。 这将创build一个可刷新的数据连接，将查询中的数据拖到数据透视表中。

这是百分之百的工作为VS-2013 Premium for C＃进行编码UItesting。 只需复制并粘贴代码就是这样。 它适用于SQL Server数据库您可以将数据保存为xls，xlsx或csv，并可以使用相同的csv进行参数化。 您需要安装以下软件包以使其正常工作。
使用System.Data.SqlClient
使用Excel = Microsoft.Office.Interop.Excel
使用SQL = System.Data
