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

Use joins.
Hibernate support for unions is selective.
If you're still uncomfortable and have a complex query, user result set transformer AliasToEntity Mapping and map your query results into your pojo.
But, in this case, I would suggest you to use a simple join.
