# Transient mapping

Use the Transient Mapping to specify a field of the entity class that is not persistent.

To create a transient mapping:

1. In the JPA Structure view, select the field to map.

2. Right-click the field and then select Map As Transient. The JPA Details view (for attributes) displays the properties for the selected.

Eclipse adds the following annotation to the field:

    @Transient
