I am using datomic with play framework. Play is amazing and datomic is fast. So a good combination overall. Since, I am new to datomic (and datalog i.e. query language datomic uses), I am unable to sort my result ( like we do, order by in sql). For example.
if my query is :
q= [:find ?title
:where
[?e :movie/title ?title]
[?e :movie/director "Dave Swag"]
[?e :movie/year ?year]
[(sort ?year)] //here I am trying to sort by year
]
It should return titles of the movies whose director was Dave Swag and result is ordered by year in which image was released. Thankyou :)
If you want to sort your result set, you will need to do this outside of the query, on the returned result set. There is an example of this on a Datomic blog post about querying in listing 20:
