Question

So if I want to do a direct SQL query using the session that Grails is using prior to supporting multiple datasources I could do:

def conn = new Sql(sessionFactory.currentSession.connection())

Now the question is that I have multiple datasources and want to grab a connection to a specific one.

How do I do that?

TIA

Answer 1

Given a datasource defined in DataSource.groovy as “dataSource_foo”, you’ll have a SessionFactory called sessionFactory_foo. So you can dependency-inject it like any other Spring bean:

def sessionFactory_foo

and use it like this:

def conn = new Sql(sessionFactory_foo.currentSession.connection())
