Question

I cannot figure out what would be the correct syntax for aliasing a field in the SQL query builder in clsql.

Below is an example, as I would imagine it might work (but obviously it doesn’t):

(defun number-of-goods-you-have-the-most? ()
  (clsql:select [item_id] [as [count [*]] 'num]
        :from [table]
        :where [is [null [sale_date]]]
        :group-by [item_id]
        :order-by '((num :desc))
        :limit 1))

I could’ve make it something like '|count(*) as num| but that’s surely not the way to do it.

Could you try (clsql:select [item_id] [count [*]] [as] 'num] ...)?
