ADO.NET :: Export Millions Of Records From Database (Oracle) To Excel?
Oct 21, 2010
I'm running a query that brings millions of records and makes the server run out of memory. I'm thinking I should get the data in chunks. So I was wondering if someone could shed some light on this or point me to another place where I can read further.
Currently, I just implemented "paging". I can now pass a "page index" parameter and "page size". So I could call 1,000 times the stored procedure with a page size of 1,000 (for 1 million records). This might be an option, but I wanted to hear someone else's opinion on how to "stream" records from oracle to the web server and then to a file.

my requirement is that SSRS 2005 report should show all records with checkboxes(or can be by any other means of flagging ?) .
Now the records for which checkboxes are checked or flagged are only to be included in the exported excel sheet or pdf .

I've programmatically generated an ASP.NET Table that is then added to a page. There is also a Button on the same page where a user can export the Table data into Excel. Very standard stuff. The data that is displayed on the page is correct but after exporting 10 rows are missing. I've checked encoding. I've compared character input: nothing unusual. Has anyone ran into this before?Here's the export code (see comment at the table...)
protected void btnExport_Click(object sender, EventArgs e)
{
string attachment = "attachment; filename=Abstracts.xls";

I am trying to export a gridview that is returned from a search form. The gridview also has paging enabled. When the searched records are found in gridview it is exporting all data.instead of exporting only the searched data.
How can I only export the records from the search results, but also the make sure the records on the different pages export also?

I have implemented excellent code for saving Gridview to Excel, CSV, Word.
I also have a Dropdown control that filters rows by selected values in a specific column, and then only rows with the selected values are displayed in the Gridview.
However when saving to Excel and other formats, all rows are saved, not just the selected ones. Is there a method to filter the Gridview by dropdown selection and be able to save only selected rows?

I have a web form that contains a GridView, which impliments Search in Grid with a TextBox and Button control in the footer. This works as I have it now. I have also implimented a Export to Excel function. The Export to Excel works by itself if the Search in Grid function is not included in the footer.The Export to Excel function errors when trying to render the Grid for the export. Is there a better way to incorporate both functions and accomplish the same thing? Am I missing something simple?

I've got an .rdlc report which I print from my .net app (C# Visual Studio 2005), where I use a RemoteReportPrinter object. I give it as parameters the server name, report name, report parameters, etc. Works fine. My question is, I would live to do an analagous export of that report to Excel. Set it up exactly the same, but have it export to Excel rather than print, probably using some other type of object than RemoteReportPrinter.
