Configuring a Basic Mapping

Use a basic mapping to map an field that contains a primitive or JDK object value. For example, use a basic mapping to store a String attribute in a VARCHAR column.

You define a basic mapping at one of the property (getter or setter method) or field level of your entity.

Optionally, you can define the strategy for fetching data from the database (see "Configuring Lazy Loading".

For more information, see "Understanding Direct-to-Field Mapping" in the Oracle TopLink Developer's Guide.

Note:

For an EJB 3.0 basic mapping code example, see: http://www.oracle.com/technology/tech/java/oc4j/ejb3/howtos-ejb3/howtoejb30mappingannotations/doc/how-to-ejb30-mapping-annotations.html#basic.

Using Annotations

Example 7-17 shows how to use the @Basic annotation to specify a basic mapping for field firstName.

Example 7-17 @Basic

@Basic()
@Column(name="F_NAME")
public String getFirstName() {
    return firstName;
}
