I have about 400 invoices for which I need to update the InvoiceLineRate and Memo columns in the InvoiceLine table. I have the data in an Excel spreadsheet with the new information, but am not sure how to update all of the respective invoices in one operation. I have experimented with using the VB Demo, MS Query, MS Access to run a SQL statement, for example
UPDATE InvoiceLine SET InvoiceLineRate = 63.36, Memo = 'Includes Adjustment of $66.64' WHERE RefNumber = '2013157'
It works fine, but I need to know how to change them all at one time, if possible. I have created a linked table in MS Access, and it appears that my best bet may be to somehow update that table from the Excel file, but I don't know how to do that.
