Distinct in ORM select expression

[czcpf]

I see we have in QueryBuilder or SelectBuilder etc.

->select([...])
->distinct() 

to make the params in select distinct in the query. However, how does one accomplish the following in ORM fashion ?

SQL/MYSQL QUERY EXAMPLE

SELECT DISTINCT rml.id AS locationId, COUNT(DISTINCT rm.id)

Better to use SELECT COUNT(alias.id) FROM (SELECT DISTINCT id FROM `my_table` ... ) AS `alias`

Like so https://github.com/espocrm/espocrm/b...apper.php#L251

Or use the mapper's count method.
