Back
where (clj)
(source)function
(where & exprs)
Accepts one or more SQL expressions (conditions) and
combines them with AND (by default):
(where [:= :status 0] [:<> :task "backup"])
or:
(where :and [:= :status 0] [:<> :task "backup"])
Produces: WHERE (status = ?) AND (task <> ?)
Parameters: 0 "backup"
For a single expression, the brackets can be omitted:
(where := :status 0) ; same as (where [:= :status 0])
With multiple expressions, the conjunction may be
specified as a leading symbol:
(where :or [:= :status 0] [:= :task "stop"])
Produces: WHERE (status = 0) OR (task = ?)
Parameters: 0 "stop"
