Imitate partitions/window functions in sqlkorma
I am trying to call the equivalent of this function using sqlkorma, and have not found the equivalent of a partition in the documentation (http://sqlkorma.com/docs):
SELECT * FROM (
SELECT DISTINCT cgi, scgi, c.id, c.name, c.address, c.city,
c.state_or_province, c.postal_code, primary_country,
ROW_NUMBER() OVER (
PARTITION BY cgi
) AS ROW_NUMBER
from ccs
join c on c.id = ccs.id) groups
WHERE groups.ROW_NUMBER = 1 ORDER BY cgi
For clarity, in my database, there is a one-to-many relationship columns variables "cgi" and "c.id"
clojure korma sqlkorma

1) Tried looking into an equivalent for "DISTINCT ON" postgresql terminology" 2) Tried aggregating data and picking the first c.id from each cgi - I don't think the aggregate modifier is the way to go 3) Tried to make the equivalent of the best answer's second query here: stackoverflow.com/questions/3800551/…

Found a simple solution to this - sqlkorma allows you to execute raw SQL, and I specified the postgresql DISTINCT ON (column_to_partition_on), column_to_partition_on, column1, column2 FROM table. Using that as the query text, this is the general format to execute raw sql using korma:
(exec-raw my-database query-text :results)
More info at http://sqlkorma.com/docs
if you end up writing raw SQL too often, you may want to check out github.com/layerware/hugsql
