Hi All,

I have two objects Person, Manager and the objects are mapped to database tables Person and Manager. I want to get all the persons having no manager at all or having manager whose name is "xyz".

SQL query to get the desired result is

I want to get the same result using HQL query and tried the following HQL query. But it is not giving expected results.

Any help on HQL query is appreciated.
