Is it possible to output generated SQL using EclipseLink without having to increase log verbosity?

Question

I want to output the SQL generated by EclipseLink to the console, during development. However, I could only do so using the logging level FINE. I have a complex domain model

Answer 1

To get the SQL for a specific Query at runtime you can use the DatabaseQuery API.

Query query = em.createNamedQuery("findMe"); 
Session session = em.unwrap(JpaEntityManager.class).getActiveSession(); 
DatabaseQuery databaseQuery = ((EJBQueryImpl)query).getDatabaseQuery(); 
databaseQuery.prepareCall(session, new DatabaseRecord());

String sqlString = databaseQuery.getSQLString();

This SQL will contain ? for parameters. To get the SQL translated with the arguments you need a DatabaseRecord with the parameter values.

DatabaseRecord recordWithValues= new DatabaseRecord();
recordWithValues.add(new DatabaseField("param1"), "someValue");

String sqlStringWithArgs = 
         databaseQuery.getTranslatedSQLString(session, recordWithValues);
