这是一个查询 EMPLOYEES 和 DEPARTMENTS 的过程，接受一个 INPUT 参数，该参数被提供给正在为游标执行的 SQL。
CREATE OR REPLACE PROCEDURE GET_EMPS_SALS_REST(MIN_SAL IN hr.employees.salary%type, p_emps_output OUT SYS_REFCURSOR) IS
BEGIN
OPEN p_emps_output FOR select FIRST_NAME
|| ' '
|| LAST_NAME EmployeeName
, SALARY
, DEPARTMENT_NAME
from DEPARTMENTS
join EMPLOYEES on DEPARTMENTS.DEPARTMENT_ID = EMPLOYEES.DEPARTMENT_ID
where salary > MIN_SAL
order by DEPARTMENT_NAME
, SALARY desc;
END GET_EMPS_SALS_REST;
/
这是一个使用 ORDS 构建的 RESTful Web 服务，它执行上述过程。
内置在 URI 中的是一个 :bind，用于将输入发送到过程。我已经定义了一个参数来捕获 refcursor 的结果。该参数被定义为“ResultSet”类型的 OUT 响应。

现在我想调用 RESTful 服务 -
这是完整的响应，请注意它是返回的整个 refcursor。如果你想要分页，你需要将它构建到你的 pl/sql 逻辑中。
