Can some tell what i am missing in the following HQL:
I have one-to-many relation between CalEvent and LaneDtls classes.
In CalEvent.java and CalEvent.hbm.xml files i have LaneDtls referred with Set. I just want to find out what syntactically i am missing in HQL.
Please help

HQL:
***
FROM CalEvent event left join fetch event.laneDtls
WHERE (event.start_date <= :bindStart AND event.end_date = :bindStart OR event.start_date BETWEEN :bindStart AND :bindEnd)
AND elements(event.laneDtls.sale_type) is not null
