@Table

From CauchoWiki

The @Table annotation specifies the name of the database table for an entity. If the @Table is not specified the @Entity name is used instead.

 @Entity
 @Table(name="test")
 public class TestBean {
     ...
 }

[edit] Annotation Definition

 public @interface Table {
     String name() default "";
     String catalog() default "";
     String schema() default "";
     UniqueConstraint[] uniqueConstraints() default {};
 }

attribute	description	default
name	the database table name	the @Entity name
catalog	the database catalog
schema	the database schema
uniqueConstraints	constraint directives when creating the database

Many applications will only use the name attribute. The uniqueConstraints are used if create-database-schema is true and the table does not exist in the database.
