我如何让我的 PostgresQL 成功执行调用?

How do i get my PostgresSQL to perform the Call Succesfully?

过去一周我一直在为此绞尽脑汁,这是一个插入存储过程,我将在应用程序中使用它来输入库存信息。出于某种原因,我不断收到相同的错误,即使我相信我正在按照文档流程来执行此操作。我做错了什么?

我对这个过程的思考过程是,我将定义应用程序将输入的变量,然后将这些变量的值分配到 table 中的列中。 这是我的程序:

CREATE OR REPLACE PROCEDURE public.add_inventory(
        _inventory_name character varying,
        _brand character varying,
        _category character varying,
        _color character varying,
        _inventory_size character varying,
        _image_link character varying,
        _sku character varying,
        _date_added date,
        _list_price money,
        _row_status integer DEFAULT 1)
    LANGUAGE 'plpgsql'
    AS $BODY$
    begin
    Insert into dbo.inventory_tb
    (inventory_name, brand, category, color, inventory_size, image_link, sku, date_added, list_price, row_status)
    values 
    (_inventory_name, _brand, _category, _color, _inventory_size, _image_link, _sku, _date_added, _list_price, _row_status);
    end;
    $BODY$;
    
    GRANT EXECUTE ON PROCEDURE public.add_inventory(character varying, character varying, character varying, character varying, character varying, character varying, character varying, date, money, integer) TO PUBLIC;

我尝试通过查询编辑器提交但未成功的“呼叫”如下:

CALL public.add_inventory(
    'Specs',
    'Gracia1',
    'Shirt1',
    'Red1',
    'Small',
    'rootfile',
    '00001',
    '2021-03-31',
    60.00,
    1
)

我得到的错误是:

LINE 1: CALL public.add_inventory(
             ^
HINT:  No procedure matches the given name and argument types. You might need to add explicit type casts.
SQL state: 42883
Character: 6

我插入这个信息的table是这样的:

CREATE TABLE public.inventory_tb
(
    inventory_id integer NOT NULL GENERATED BY DEFAULT AS IDENTITY ( INCREMENT 1 START 1 MINVALUE 1 MAXVALUE 2147483647 CACHE 1 ),
    inventory_name character varying(100) COLLATE pg_catalog."default" NOT NULL,
    brand character varying(100) COLLATE pg_catalog."default" NOT NULL,
    category character varying(100) COLLATE pg_catalog."default" NOT NULL,
    color character varying(100) COLLATE pg_catalog."default" NOT NULL,
    date_added date NOT NULL,
    inventory_size character varying(50) COLLATE pg_catalog."default" NOT NULL,
    list_price money NOT NULL,
    image_link character varying(100) COLLATE pg_catalog."default" NOT NULL,
    sku character varying(100) COLLATE pg_catalog."default" NOT NULL,
    row_status integer NOT NULL,
    CONSTRAINT "inventory_tb_PK" PRIMARY KEY (inventory_id)
)

TABLESPACE pg_default;

ALTER TABLE public.inventory_tb
    OWNER to postgres;

删除旧过程并将其定义为使用相应类型类别的首选数据类型:

CREATE OR REPLACE PROCEDURE public.add_inventory(
    _inventory_name text,
    _brand text,
    _category text,
    _color text,
    _inventory_size text,
    _image_link text,
    _sku text,
    _date_added date,
    _list_price numeric,
    _row_status integer DEFAULT 1
) LANGUAGE plpgsql AS
$BODY$
BEGIN
    INSERT INTO dbo.inventory_tb
        (inventory_name, brand, category, color, inventory_size, image_link, sku, date_added, list_price, row_status)
    VALUES
        (_inventory_name, _brand, _category, _color, _inventory_size, _image_link, _sku, _date_added, _list_price, _row_status);
END;
$BODY$;

那么PostgreSQL就可以根据type conversion rules隐式转换数据类型,不需要显式类型转换。

数据类型与 table 中的数据类型略有不同并不重要,因为 PostgreSQL 将在赋值时应用类型转换。

现在通话正常:

CALL public.add_inventory(
    'Specs',
    'Gracia1',
    'Shirt1',
    'Red1',
    'Small',
    'rootfile',
    '00001',
    '2021-03-31',
    60.00,
    1
);
CALL
