title: In @Table(name = "tableName") - make "tableName" a variable in JPA
body: <p>I am using JPA and I need to make the "tableName" a variable. </p>
  
  <p>In a database, I have many tables, and my code needs to access the table where I specify it to read.</p>
  
  <pre><code>@Entity
  @Table(name = "tableName")
  public class Database implements Serializable {...............}
  </code></pre>
  
  <p>Any ideas?</p>
