I have used FunctionMappingStore to map a simple function, but now I have a need to map to a table-value function. Is this possible?

Thanks, Ed

I never tried, but I think it should be possible. The tricky part would be that the function mapping should return the correct type (DataTable?). Please give it a try,

If you want to join with the table function it's not going to work however. Table functions for joins aren't supported.

Perhaps there is another way to do it?

Is there a way to populate a datatable with the results using the DataAccessAdapter?

You can use DynamicList or Stored Procedures (the SP call you table-function). Maybe if you post some approximate SQL or some code of the function and what data you can fetch, we can give you some options.
