Hello,

I have a problem, I use Spring and JPA in my application and I have named queries in orm.xml. I need to change some named queries in runtime or change SQL generates for Hibernate.

Any suggestion??

Thank you in advance

to change the SQL you can either extend the dialect or define the full SQL query by using namedSQLQueries instead of named HQL queries.
You can't change named queries after the SessionFactory is started, that defeats the purpose of naming them.
