Validations when we use GET method

Question

Hi Team,
I am using GET method with the following URL(example)
http://IP:8080/ords/schema_name/office/users/{user_id}
URI template : office/users/{user_id}
method:get
source type : Feed
Source : select * from emp where empno = :user_id;
Using the above URL I am able to get all the specified user details in the browser.
I want to add the validations to the service now, and response should be user defined.
Ex : when user not in the database
then respond with the error code and error name in JSON format ex:
items:
error code : 404
message: "somthing wrong"
I am not sure how we can achieve this functionality when we use SQL query.
Please suggest any possible solutions for this.
thanks
Chandran

grant dba_users view to apex and change the sql like this:
select * from emp where empno = :user_id and exists (select 1 from dba_users where username=:user_id);
