Export to mora than one excel sheet.

Question

Hello Marvel team,
I am looking to do something related to the export of data to an excel file and I am asking if one of you has do something like the following :
I need, on a click on a button export some data to more than one sheet in the same excel file.
I looked to what askTom propose, with the sylk format:
http://asktom.oracle.com/pls/ask/f?p=4950:8:::::F4950_P8_DISPLAYID:728625409049
and this can resolve my problem in part, with sylk I can have what I want but only in one sheet and for me it's very important that I can export to more than one sheet in the same excel file.
Thanks for any help!

Using POI, you can create a native Excel Workbook with more than one Worksheet.
For a first step using POI follow the steps posted under:
"Export to Microsoft Excel from PLSQL Procedure"
Re: Export to Microsoft Excel from PLSQL Procedure
The following examples creates an excel with more than one sheet (and does a little bit of formating).
Load this as described above to your 10g Database and build a pl/sql wrapper function around it:
-- bof --
import java.io.*;
import org.apache.poi.hssf.usermodel.*;
import org.apache.poi.hssf.util.*;
public class HelloExcel {
public static void main(String[] args) {
HelloExcel d = new HelloExcel();
d.write(null);
public static String write(String text) {
String result = "successful";
HSSFWorkbook wb = new HSSFWorkbook();
HSSFSheet sheet1 = wb.createSheet("first sheet");
HSSFSheet sheet2 = wb.createSheet("second sheet");
// style
HSSFCellStyle style = wb.createCellStyle();
style.setFillForegroundColor(HSSFColor.LIME.index);
style.setFillPattern(HSSFCellStyle.SOLID_FOREGROUND);
HSSFFont font = wb.createFont();
font.setColor(HSSFColor.RED.index);
style.setFont(font);
HSSFRow row = null;
HSSFCell cell = null;
// Create a row and put some cells in it. Rows are 0 based.
row = sheet1.createRow((short)0);
// Create a cell and put a value in it.
cell = row.createCell((short)0);
cell.setCellValue(1);
cell.setCellStyle(style);
// Or do it on one line.
row.createCell((short)1).setCellValue(1.1);
row.createCell((short)2).setCellValue("This is a string 1");
row.createCell((short)3).setCellValue(true);
// Create a row and put some cells in it. Rows are 0 based.
row = sheet2.createRow((short)0);
// Create a cell and put a value in it.
cell = row.createCell((short)0);
cell.setCellValue(1);
// Or do it on one line.
row.createCell((short)1).setCellValue(1.2);
row.createCell((short)2).setCellValue("This is a string 2");
row.createCell((short)3).setCellValue(false);
// Write the output to a file
try {
FileOutputStream fileOut = new FileOutputStream("c:\\temp\\HelloExcel.xls");
wb.write(fileOut);
fileOut.close();
} catch(Exception ex) {
result = ex.getMessage();
return result;
-- eof --
hope that helps,
