Linq to sql return dynamic table

Question

Hi,
I am looking to use linq to sql like I did with ADO and return a dynamic table like I did with a datatable.
I will not know what table/fields will return until runtime.  I later want to loop through the return table and get the field names and values.
if this was a datatable it would look something like
System.Data.
DataTable
dt = new
DataTable();
foreach
(DataRow
dr in
dt.Rows )
string
fieldName = dt.Columns[0].ColumnName;
string
values = dr[0].ToString();
Here is my linq to sql but dynamic will not work
var
recordSet = (db.ExecuteQuery<dynamic>(sql,

You seem to be having the same issue I am (for which, by the way, no one seems to have the answers);
1.  A data object being passed to your class/methods
2.  Another object being passed containing the "fields"/properties the user wants returned from the data
I've been trying to make something like this work
List
IQueryable
subset = from
a in
rawdata select
(<<dataFields>>);
... Tantamount to passing a fields list into an SQL query (macro expansion?).  Unfortunately, LINQ wants to treat whatever is passed in the select
as a literal.
If you come up with an answer, please let me know.  I have solved every other issue in my code (including a rather clever GroupByMany cobbled
together from various leads from other posts), but am stuck at this one.
<string>
dataFields = datapoints.ToList<string>();
