Question

我正在PgAdmin中创建一个存储过程，以便将数据插入到不同表的表中。我尝试了以下代码，但我被要求返回类型。我需要添加什么？

另外，如何使用此过程将数据从不同的表中插入表中？

CREATE OR REPLACE FUNCTION stager.ProductDimSP 
(
cat_name character varying(25)  ,
pr_name character varying(40) ,
pr_id character varying(6)  ,
disc boolean      
) RETURNS NULL ON NULL INPUT AS
$$
BEGIN
INSERT INTO stager."ProductDimTable"
  ( 
    category_name, product_name, product_id, discontinued           
  ) 
 VALUES 
  ( 
   cat_name, pr_name, pr_id, disc
  ) 
END
$$
LANGUAGE 'plpgsql';

Answer 1

CREATE OR REPLACE FUNCTION stager.ProductDimSP 
(
 cat_name character varying(25)  ,
 pr_name character varying(40) ,
 pr_id character varying(6)  ,
 disc boolean      
) 
RETURNS VOID -- this defines a function with no return value
AS
$$
BEGIN
INSERT INTO stager."ProductDimTable"
  ( 
    category_name, product_name, product_id, discontinued           
  ) 
 VALUES 
  ( 
   cat_name, pr_name, pr_id, disc
  ); -- this semicolon was also missing
END
$$
LANGUAGE plpgsql;  -- do not put the language name in quotes
