问题
Is it possible to do an "in" criteria using the GORM criteria. I'm looking for the equivalent of the following SQL
select * from Person where age in (20,21,22);
If it was possible I guess the syntax would be something like:
def results = Person.withCriteria {
in "age", [20, 21, 22]
}
回答1:
The Grails createCriteria documentation includes an example of using the in clause:
'in'("holderAge",[18..65])
or not{'in'("holderAge",[18..65])}
The documentation includes this note:
Note: 'in' is a groovy reserve word, so it must be escaped by quotes.

Yep, you have it almost exactly right. Just change in to 'in', since in is a keyword in groovy.
