sql - invalid identifier -


i trying run query reason keep giving me below error

ora-00904: "distance_in_metres": invalid identifier

can please sort issue, appreciated or guidance on this.

you can not use column defined in select clause in same select clause. logically select clause evaluated @ once. simplified example:

select 1 test, 2 * test dual  ora-00904: "test": invalid identifier

as kashi points out in comment, distance_in_metres referenced in case expression following definition of distance_in_metres in same select clause, , error coming from.
