hibernate - How to count Hibernate Results without fetching them in Grails?

Question

Using a HQL query like this:

def accounts = Account.executeQuery("select distinct a.number from Account a") 
def accountSize = accounts.size()

This gives the accountSize but the problem is that the accounts will be fetched from Hibernate as well. Is there a command that allows to compute the size of the query result without fetching the result?

Answer 1

Account.count()Account可以给你表格的总行数。

那是你需要的吗？

如果您需要 HQL，那么

def accountSize = Account.executeQuery("select count(distinct a.number) from Account a")
