- [Instructor] Our finished process should look like this. We get the files from the source folder and we loop through the files performing the following steps. We determine which customer the file is from based on the file name, here. And then we set the appropriate parameters for the bulk insert procedure. So for our World Bank customer, it's tab-separated. The row terminator is char 10, it's a Unicode file and we SET the bank for our other customers, it's comma-separated. Character 10 linefeed row terminator, it's an NT file, so it's just char. We SET the total file path, the full file path, and source directory and file name. We execute the import into the appropriate staging table. This is successful, so it returns a one, then we check the integrity, so we have separate procedures for the different file formats, and then we import that into our generic staging table. Also for successful, we perform the schedule upload where we create and update the schedule records, if that is successful, then we check for errors. We update the production table. If it's the World Bank, then we create the vault orders, and also, which in turn sends out emails notifying of vault orders, and then for all customers, we send the email confirmation. If any file, if any errors have been logged for that file, we also send those, and finally, we move the file from the source directory to the archive directory and then rinse and repeat, and we will keep processing files until there are no more files in our files data set.
