Now i have to export all reports into excel sheet where each reports (all 6 reports) should put in different sheet in excel workbook. I can do for one report in which i just give HTML Table and render it in to .xls file but i dont know how to render second report in second sheet in same excle file.

The possible solutions I have known as per my knowledge, to insert the data are
1. To insert one record at a time which makes 30,000 database hits. How will this affect the performance? 2. To use liked servers - bu this is not working for me.I do not have database permissions to use linked servers. So, the only option i have is the first one.
