csvimport / csvexport

‘csvimport’ and ‘csvexport’ are tools used to import/export CSV files to the Machbase server.

The options have been simplified for simpler use of the CSV file using the machloader.

In addition to the options described below, all options available in machloader are available.

csvimport

CSV files can be easily entered into the server using csvimport.

* You can do this with just the table name and data file name without specifying the option.
