I wonder whether I can realize the opration of "update" for the CSV files just as what "update" can do for a database? Simply speaking, I use CSV files as midia of output to save the datas. Whether I can update the file just as the opration "update" does for a table in database?
Perl CPAN provides a DBD::CSV database connector. It means that you can use a CSV file as a database and perform update as you would do with MySQL or Oracle. Would that feature be interesting?
Thanks for your help, unfortunately, I use java and
You can try to do the update action in database, then query the data and output the result to original csv file.
