In a Grails 2.1 application, I'm having trouble getting a criteria query to behave like some handwritten sql I've got.
So-here's some background info:
The table is in a reporting db and has the following ddl:
completed_case table columns
id
completedDate
caseState
caseId (this field is not unique)
state
some other columns
customerName, other data columns
A row is added to this table whenever a value for that case changes, so there are often >1 rows per caseId.
I've been tasked with finding the first row for each case within a completedDate range. I've got some hacky sql that seems to get me the values I want:
select * from dbo.completed_case where id in
(select min(id)
from dbo.completed_case cci
group by case_id
having ((min(completed_date) > convert(datetime, 'Oct 19 2012 11:01AM', 100)) and
(min(completed_date) < convert(datetime, 'Oct 21 2012 11:01AM', 100)))) and
status = 'DIAGNOSED'
But I'm not sure how to translate this query into a Grails/Gorm CriteriaQuery. I was guessing the following(using a detached criteria to do the sub select), but it seems like DetachedCriteria doesn't have groupPropery() so I'm a bit lost.
Anyways, here's my guess that includes the not-valid call to groupProperty:
HibernateCriteriaBuilder criteria = CompletedCase.reports.createCriteria()
def results = criteria {
eqAll("id", new DetachedCriteria(CompletedCase).build {
projections {
min("id")
}
groupProperty("caseId") //XXX this method doesn't exist on DetachedCriteria
between("completedDate", startDate.toDate(), endDate.toDate())
})
eq("status", "DIAGNOSED")
fetchMode 'AssociatedTable', FetchMode.JOIN
}
Is there some way to generate this query using the interfaces provided by Gorm/Grails?
thanks

I just did it using hql.
select cci from CompletedCase as cci where id in (
select min(id) from CompletedCase group by caseId
) and cci.completedDate > :startDate and cci.completedDate < :endDate and cci.status = :status
order by cci.id
