For both these types of records an optional field delimiter and an optional record delimiter can be specified. The field delimiter, when specified, should be a single character. By default, comma is the field delimiter. The record delimiter can be specified in the commands file and it can be more than one character. By default, the newline character, \n, is the record delimiter.

5.5THE COMMANDS FILE

The commands file specifies:

•Record format for the output file

•Query which is to be used for exporting data

There is no file naming convention for the commands file. For example, the commands file name to load the orders table could be orders.cmd.

The commands file must contain the following parts:

•The DEFINE RECORD statement

•The FOR RECORD statement
