With most commands for loading and unloading, you can specify the external data type and the data format that the relevant field values in the data stream have or should have.

You can specify the data format in load and unload commands as a processing specification for the data stream (syntax rule stream_format_spec).

code_spec
number_spec
date_spec|time_spec|timestamp_spec
null_spec
bool_spec
int_spec
separator_spec|delimiter_spec

The specified data format applies to the columns that have the corresponding internal database data type.
