Hi there,
I have a problem here, not sure how to tackle this one. I have a datatable (dtMain) which has columns which I want to replace the values in a datatable with the descriptor of the lookup tables.
Anyone have any ideas at all? Is it even possible?
Many many thanks in advance!
Re: Lookup Multiple Datatables into 1 datatable
Would it not be better to just execute a query against the database and get the data in the format you want it in the first place? If not, you can perform a LINQ query to join the data in the two DataTables and then call CopyToDataTable to create a new DataTable containing the results.

I agree, making one query with proper joins will save you a lot of trouble later.
If they're in different databases, you can always use a DB link
