I know ig grid needs a IQueryable object.

I know you apend the paging function in GridDataSourceAction aginst Linq. 

My question is that I only have some sql now. How can I convert these SQL to an IQueryable object, and I don't want to lost the delay query feature.

For example. I have "Select * from Issues''. Issues table has a lot of rows, So I need the paging feature.

following is the code I want:

[GridDataSourceAction]
[ActionName("PagingGetData")]
public ActionResult PagingGetData()
{
 var ds= ConverSqlToQuerable(" I have "Select * from Issues'"); 

   //Here, I don't want query data from DB.
   //I have a lot of Rows in DB. So I need deley DB query 
   // until GridDataSourceAction appends the
   // paging filter at the tail of my sql.

    return View("RowSelection", ds);
}

My question looks like an Linq question more. But I'm hoping get some suggestion from your guys.

Thank you!.
