Question

How do I translate:

SELECT COUNT(*) AS `count`, `a` FROM `b` GROUP BY `a` ORDER BY `a`

into grails or gorm query?

Answer 1

working in grails 1.2.1

def c = C.createCriteria()
def pl = c.list {
    projections {
        countDistinct 'id', 'myCount'
        groupProperty 'a'
    }
    order ('myCount', 'desc')
}

the answer is for example

[[10,a3],[2,a1],[1,a2]]
