I want to select certain amount of data from one table. Based on those data, I want to check another two tables and insert into 2 tables.

So I want to iterate the resulted data. Which way is better(faster) and reasonable using DataReader or DataTable?

Thanks in advance

    You end up creating a reader to fill the table. The reverse isn’t true, So I would stick with the dataReader.
