I developed app using JPA Toplink which uses JPQL. According to my research JPA will call more SQL than what JPQL statement look like.

I’m looking for some JPQL analyzer tools like I can execute JPQL or run my application and
tells me how many actual SQL being run.

Is there anything like that available?

UPDATE
Added the following in my persistence.xml as suggested and my Netbean IDE now shows actual SQL generated by JPQL 😀 

  <properties>
      <property name="eclipselink.logging.logger" value="JavaLogger"/>
      <property name="toplink.logging.level.sql" value="FINE"/>

    I don’t think there can be a generic analyzer as the behavior is provider specific. You can however look at the SQL’s being executed by enabling appropriate logs of the JPA provider you are using.
