Configuring Field Name

All object-relational mappings require the name of database field to which their specified attribute is mapped. This field name can be the column name of a database table or the name of a field in an object type created on the database.

Table 50-5 summarizes which object-relational mappings support this option.

Table 50-5 Mapping Support for Field Name

Mapping	Using TopLink Workbench	Using Java
Object-Relational Structure Mapping
Object-Relational Reference Mapping
Object-Relational Array Mapping
Object-Relational Object Array Mapping
Object-Relational Nested Table Mapping

Using Java

Use the object-relational mapping method setFieldName to specify the database field to which the attribute is mapped.

Example 50-3 shows how to use this method with an ObjectArrayMapping that maps the Employee class attribute phone to database field name PHONE_NUMBER.
