[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-2541) no-arg function inside "vector expression" not properly replaced with Dialect function mappings

no-arg function inside "vector expression" not properly replaced with Dialect function mappings ----------------------------------------------------------------------------------------------- Key: HHH-2541 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2541 Project: Hibernate3 Issue Type: Bug Components: query-hql Reporter: Steve Ebersole Assignee: Steve Ebersole Priority: Minor For an example of this, see org.hibernate.test.component.basic.ComponentTest#testComponentQueries against a Sybase database. The issue is the third query in that test: from Employee e where e.person = ('steve', current_timestamp) The first grammar (hql.g) is currently the one responsible for deciding whether an IDENT node represents a METHOD_CALL. However, it currently does this by seeing if the IDENT is immediately followed by an '('. Here, the current_timestamp method call is not because it is no-arg and so hql.g does not retask the IDENT as a METHOD_CALL. And actually this is correct. The code in hql.g is simply trying to get the common case. And we do not want to blindly look up the IDENT text in the Dialect to see if it matches a mapped function name (because it might also represent a property name, which should take precedence). The solution is to account for this in the second grammar (hql-sql.g) during recognition of a vector expression. Actually, the correct correct solution is better precedented recognition of atomic expressions...
