Can we concatenate two properties in Hibernate HQL query?

Question

Lets say I have one table with two columns firstname and lastname with String datatype. Normally I write my hql query like

"select firstname,lastname from contact"

Can I write a hql query which concatenates both property ?

Maybe something like "select firstname+lastname as fullname from Contact"

Answer 1

select concat(c.firstname, c.lastname) as fullname from Contact c

or, if you want a separator:

select concat(c.firstname, ' ', c.lastname) as fullname from Contact c

See the documentation.
