How do you bulk delete records in Grails/GORM?

Question

I have a table which has records that need to be periodically cleared according to a set of criteria.

I was expecting that I could use the criteria builder to just delet

With Grails 2.0 you can use a detached query like this:

Agency.where { }.deleteAll()

Note that you don't get the listeners and whatnot executed, but it does execute through to the database, AND it is compatible with the mocked domain stuff, as in:

void testWhatever() {
    mockDomain(Agency, [])
    saveABunchOfAgencies() // saves 10 of 'em
    assert Agency.count() == 10

    Agency.where { }.deleteAll()

    assert Agency.count() == 0   // Joy!
}

That being said the GORM unit test mocks have a bunch of gotchas but are in general pretty neat.
