使用ExcecuteQuery计数和分组

Question

如何通过activationDate获取计数？

我试过这个查询

def mapQuery6= new HashMap()

def query6 = "SELECT count(al.id) as totalCount,al.activationDate from Card al where and TO_DAYS(al.activationDate) > TO_DAYS(:from) and TO_DAYS(al.activationDate) <= TO_DAYS(:to) GROUP BY al.activationDate "

mapQuery6.from = params.from
def to = new Date().parse('dd/MM/yyyy HH:mm:ss', params.to+ " 05:00:00")
to.setDate(to.getDate() + 1)

mapQuery6.to = to

println "query 6 = "+query6 

def activecard = Card.executeQuery(query6,mapQuery6)[0] 

println "activecard = "+activecard

我想要这样的结果

如果iam使用Group by al.activationDate打印时的结果是

activecard = [1, 2014-06-17 20:27:11.0]

如果没有group by al.activationDate，结果是

activecard = [6, 2014-06-27 20:27:11.0]

所以我想每个月都有一个计数号码.. 示例2014-07-xx有3个计数，2014-06-xx 2和2014-05-xx只有1个

尝试按月分组

GROUP BY MONTH(al.activationDate)
