Using sails.js (0.10.5):
I can't figure out how to achieve a groupBy/count using waterline/sails. What I would like to have is something like:
SELECT customer_id, COUNT('') FROM customer_data GROUP BY customer_id;
or
SELECT customer_id, SUM(1) FROM customer_data GROUP BY customer_id;
I wasn't able to achieve this using count nor sum (using a constant):
Customer.find({ groupBy:['customer_id'], count: true })
or
Customer.find({ groupBy:['customer_id'], sum: [1] })
Both will end in an error, the first "missing calculation" and the second "SQL syntax error".
I can make a grouping using sum with an existing column (sum: ['id']) but that does not get me the count.
Am I using the API wrong?
please use Customer.query('SELECT customer_id, SUM(1) FROM customer_data GROUP BY customer_id', function(err,results){})
if you don't want use sql, you can like this to use
Customer.find({groupBy:'customer_id'}).exec
