# Default output specifications

In addition to explicitly listing attribute names as part
of the AQL sentence, there are three features that can be used to
specify default output specifications.

These specifications output the default attributes when attributes are not explicitly specified
 in the AQL sentence and are listed as follows:

- Attribute names can be listed as a macro in the File-defining items.

- Default attribute items (Access Query Language) can be created.

- Temporary attribute items can be created.
