I tried doing like this:--
In controller--
def get_data():
custdata = db.executesql(qry, as_dict=True)
return response.json(custdata)
And in View,
other code is as earlier (hence omitted)
sAjaxSource: {{=URL('MIS','get_data')}},
Still, the dataTable is blank.
Pl. help.

try
def get_data():
custdata = db.executesql(qry, as_dict=True)
return response.json(custdata.as_list())
also go to this link http://yoururl/app/controller/get_data
you should see a json response

He's already using as_dict=True in the executesql call, so doing
custdata.as_list() shouldn't be necessary.
Is MIS your app name, or the controller name? If it's the app name, your URL
call also needs the controller name, or it will think MIS is the controller
and the Ajax call will fail.

a='MyWheels', c='MIS', f='get_data'.
So, {{=URL('MIS','get_data')}} should work.
But I do not get the data in dataTable.

What happens if you go to /MyWheels/MIS/get_data? Do you get the proper JSON
returned? If so, then the problem is probably in your client-side JS code.
Also, on the client side, check in Firebug (or similar) to see if the Ajax
call is getting made properly, and if it is returning the JSON. You
Note, you might also check out PowerTable (
https://bitbucket.org/rochacbruno/powertable), which is a web2py plugin for
DataTables. There's also a jqGrid widget that's part of plugin_wiki (you can
use it even on non-wiki pages) -- see

As suggested by the community, I am trying to export json data to
dataTable.
But only blank dataTable is rendered (with desired formatting, search
box, etc.)
Pl. introspect into my code as to where I have a mistake.
Data is not displayed (as returned by get_data method).
I have made sure that the

As suggested by Caleb, I prepared the HTML myself (in the
controller).
Then returned the generated html to the View and rendered it there.

If you really need to return 10,000 records to the browser, you should be
returning json and then rending with some sort of data grid.
why you need to return 10k records in one go ?

@Sebastian, @pbreit,
I understand what you mean to say.
If I get you rightly, I should fetch only a limited no. of rows
through pagination.
It makes sense for most of the situations.
But for some cases, rendering all the records on single page is
required.
e.g. consider a big automobile workshop.
We used YUI DataTables at my last company and they worked really well but we
only got up to around 1000 records on a page (with very quick paging,
filtering and sorting). I've been wanting to hook them up to Web2py but
haven't needed it so far.

Have you tried pasring the data using your 0.078 second method into a
json format and using jQuery to parse it?
Maybe check out DataTables new virtual scrolling feature:
http://datatables.net/blog/Introducing_Scroller_-_Virtual_Scrolling_for_DataTables.
I think jQgrid may have a similar feature as well.
