    <p>I need to <strong>make an audit module</strong> to my Java Web App. I use EclipseLink, not Hibernate (can't use Envers). I searched a lot some way to get the SQL or JPQL that JPA is executing, so I could log something like this:</p> <pre><code>System.out.println("User " + user + " from " + ip_address + " executed " + jpa_statement + " at " + new Date()); </code></pre> <p>Actually, I'll save this info into a history database's table. So I can easily retrieve this info any time I want. That's why "<strong>SHOW SQL</strong>" parameters are not enough to me. I really need the SQL string, so I can manipulate it at my source code.</p> <p>I found at JPA spec the <strong>EntityListener</strong> feature and thought it was the perfect place to put my logging code. For example, the postUpdate method could log the time the object was updated. But my problem is that I can't have the SQL the was executed.</p> <p>Here is an example of what I mean:</p> <pre><code>public class AuditListener { @PostUpdate public void postUpdate(Object object) { User user = (User)FacesContext.getCurrentInstance().getExternalContext().getSessionMap().get("user"); String ip_address = (User)FacesContext.getCurrentInstance().getExternalContext().getSessionMap().get("ip_address"); String jpa_statement = object.getSQL(); System.out.println("User " + user + " from " + ip_address + " executed " + jpa_statement + " at " + new Date()); } } </code></pre> <p><strong>But "object.getSQL()" doesn't exists. So how can I get the SQL statement?</strong></p> <p>If anyone could point me into the right direction, I would appreciate!</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
