问题 I had this code taken from Reza Aghaei’s solution, which had helped me solve the problem for single DataSet using Microsofts Reportviewer Control on Winforms. Working Part: Calling Form: string sql = "SELECT bk_book_details.id, bk_book_details.book_id, bk_book_details.book_no, bk_book_details.book_name, bk_book_details.edition_id, bk_book_details.condition_id, bk_book_details.publication_year, bk_book_details.price, bk_book_details.purchase_price, bk_book_details.reference_no, bk_book_details

问题 I have the following code to alter the data, now I actually want to write said data back to the TESTS_TMP table in the Access database, how do I do that?
