Question

我想在postgres函数中返回一个查询结果。我试过这个并且工作得很好：

CREATE OR REPLACE FUNCTION getIncomingAreaMovements(v1 integer)
RETURNS integer AS $$
DECLARE
BEGIN
    return id_part_movement From part_movement where  id_area_final_destination = $1;
END;
$$ LANGUAGE plpgsql;

事情是我需要一些东西来返回结果：

Select * From part_movement where  id_area_final_destination = $1;

我需要什么回报或者我应该改变什么来实现这一目标？

Answer 1

这可以通过一个简单的SQL函数来完成：

CREATE OR REPLACE FUNCTION get_data(v1 integer)
RETURNS setof part_movement 
AS 
$$
   Select * 
   From part_movement 
   where id_area_final_destination = v1;
$$ LANGUAGE sql;

手册中可以找到更多细节和示例：
