Using Hibernate query : colon gets treated as parameter / escaping colon

Question

return sessionFactory.getCurrentSession().
            createQuery(\"FROM Weather WHERE city_id = :id AND date \" +
                    \"BETWEEN now()::date AND now         


        

Answer 1

return sessionFactory.getCurrentSession().
        createQuery("FROM Weather WHERE city_id = :id AND date " +
                "BETWEEN cast(now() as date) AND cast(now() as date) + (:days - 1)").
                setInteger("id", city_id).setString("days", days).list();

Answer 2

I just had this problem, had to use casts, so I tried some stuff to make it work. Turns out you escape : in hibernate with \

However, in java, to print \ to begin with, you have to escape it with \.
So, if you want to put a : in your SQL hibernate query, you have to write it like: \\:

And if you wanted to cast in PostgreSQL, such as in my case, you would have to, for example: field\\:\\:int if you wanted to cast some field as an integer.

Answer 3

Named parameters take a colon ':' like this Is that what you were looking for ?

Answer 4

You escape : with ::. I think.

Or try a nativequery

Answer 5

Since you're on Postgres, I would change the date() completely:

return sessionFactory.getCurrentSession().
        createQuery("FROM Weather WHERE city_id = :id AND date " +
                "BETWEEN current_date AND (current_date + (integer :days - 1))").
                setInteger("id", city_id).setString("days", days).list();

Answer 6

Take a look at http://www.postgresql.org/docs/8.1/static/sql-createcast.html

Try using cast. To me it worked like a charm.
