I thought it would be good to have an API that will call any registered queries upon connecting to the database, and maybe ones before returning it to the connection pool. I'm thinking it should be called in the implementations of ConnectionProvider and MultiTenantConnectionProvider. The basic purpose would be so you can set certain parameters. For example in setting the timezone in PostgreSQL: SET SESSION TIME ZONE 'UTC'; Or in MySQL: SET SESSION time_zone = 'Europe/Berlin'; This would of course require dialect handling, and access to some of the configuration settings given to the SessionFactory. There should also be a way for users to customize these with a per-persistence-unit configuration of some sort. They might want to pass other such runtime tweaks. Someone may want to send something like this to their MySQL: SET SESSION sql_mode = 'TRADITIONAL,ANSI'; I realize it's too late to think about this for 6.0, but it's something to consider for later on. _______________________________________________ hibernate-dev mailing list hibernate-dev(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/hibernate-dev
