My JPA knowledge is a bit rusty and I only worked with Hibernate before.
Which JPA implementation do you use?
In case of Hibernate you can enable logging:
org.hibernate.SQL => DEBUG
org.hibernate.type.descriptor.sql => TRACE
If you also use Spring you can try the following config instead:
spring.jpa.show-sql = true
spring.jpa.properties.hibernate.format_sql = true
