If you do not specify native (-n) or character (-c) format, bcp prompts you interactively
The default values for these prompts produce the same results as using the native format, and provide a simple means for copying data out of a database for reloading into the SAP ASE server later.
If you are copying data to or from the SAP ASE server for use with other programs, base your answers to the prompts on the format required by the other software.
These four prompts provide an extremely flexible system that allows you either to read a file from other software or to create a file that requires little or no editing to conform to many other data formats.
