having (clj)
(source)function
(having & exprs)
Like `where`, accepts one or more SQL expressions
(conditions) and combines them with AND (by default):
(having [:> :count 0] [:<> :name nil])
or:
(having :and [:> :count 0] [:<> :name nil])
Produces: HAVING (count > ?) AND (name IS NOT NULL)
Parameters: 0
(having :> :count 0)
Produces: HAVING count > ?
Parameters: 0
(having :or [:> :count 0] [:= :name ""])
Produces: HAVING (count > ?) OR (name = ?)
Parameters: 0 ""
