/**
* Specifies multiple secondary tables for an entity.
*
*
* Example 1: Multiple secondary tables assuming primary key columns are named the same in all tables.
*
* @Entity
* @Table(name="EMPLOYEE")
* @SecondaryTables({
* @SecondaryTable(name="EMP_DETAIL"),
* @SecondaryTable(name="EMP_HIST")
* })
* public class Employee { ... }
*
*
* Example 2: Multiple secondary tables with differently named primary key columns.
*
* @Entity
* @Table(name="EMPLOYEE")
* @SecondaryTables({
* @SecondaryTable(name="EMP_DETAIL",
* pkJoinColumns=@PrimaryKeyJoinColumn(name="EMPL_ID")),
* @SecondaryTable(name="EMP_HIST",
* pkJoinColumns=@PrimaryKeyJoinColumn(name="EMPLOYEE_ID"))

* public class Employee { ... }
