How can I check what parameter is finally passed with the query?

Question

Is there any way I can check, how is the query being framed or what values are being passed ? I want to check for this query :

String hql = "from Scheduled where stime <= current_time()"; // QUERY

List list = session.createQuery(hql).list();

I want to know what value of current_time() is being sent ?

Answer 1

current_time() is not replaced with a specific time in hibernate - it is passed as part of the SQL to the database and is evaluated there. Therefore, current_time() will be whatever the current time is on the database server at the time the statement is executed.

Answer 2

You can enable Hibernate logging and these two params should be of help to you:

• org.hibernate.SQL - Log all SQL DML statements as they are executed
• org.hibernate.type - Log all JDBC parameters

Answer 3

If your underlying database is SQL Server, then another option is SQL Profiler.

Answer 4

Here are entries from log4j.properties which works for me to print hibernate queries and parameters.

log4j.logger.org.hibernate=DEBUG, stdout
log4j.logger.org.hibernate.SQL=DEBUG
log4j.logger.org.hibernate.type=TRACE,stdout
