Hello guys
I am running into a problem, basically I need to translate the follow SQL (to HQL)
Code:
SELECT count(*), status, date(eventDate)
from call_detail
where clientid = 32 and date(eventDate)
GROUP BY status, date(eventDate)
to HQL (which i am doing as follows)
Code:
SELECT count(*), status, date(eventDate)
from CallDetail
where clientId = 32 and date(eventDate)
GROUP BY status, date(eventDate)
This gives me the following exception
Code:
Exception in thread "main" java.lang.IllegalStateException: No data type for node: org.hibernate.hql.ast.tree.MethodNode
\-[METHOD_CALL] MethodNode: '('
+-[METHOD_NAME] IdentNode: 'date' {originalText=date}

but if I run the same HQL without the sql date() function in the select clause the HQL gives no exception but thats not the result I want.
Now the reason I am using the date() function is that my date column is database table is of type "timestamp" which means the format is like "dd/mm/yyyy hh:mm:ss" and what I have to do in my query is to group by the date part i.e. (dd/mm/yyyy) and the status. OR to get counts of different status by date (only no time)
Any idea how can I achieve this using HQL ?
What I am using is
-Hibernate 3.2.2ga
-EnterpriseDB
-JDK 1.5
