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 { ... }
