【参考方案1】：

尝试使用 SELECT..INTO 子句和简单的用户变量 -

CREATE PROCEDURE ManufactureAdd(
  p_manufactureName longtext,
  p_address longtext,
  p_phone varchar(50),
  p_email varchar(50),
  p_description longtext)
BEGIN
  SELECT IFNULL(MAX(manufactureId + 1), 1) INTO @p_manufactureId FROM tbl_Manufacturer;

  INSERT INTO tbl_Manufacturer (manufactureId, manufactureName, address, phone, email, DESCRIPTION)
    VALUES (@p_manufactureId, p_manufactureName, p_address, p_phone, p_email, p_description);

  SELECT @p_manufactureId;
END

【参考方案2】：

试试这个：

CREATE PROCEDURE ManufactureAdd(
    p_manufactureName LONGTEXT,
    p_address LONGTEXT,
    p_phone VARCHAR(50),
    p_email VARCHAR(50),
    p_description LONGTEXT
)
BEGIN
   DECLARE p_manufactureId INT;
   SELECT IFNULL(MAX(manufactureId+1),1) INTO p_manufactureId FROM tbl_Manufacturer;

   INSERT INTO tbl_Manufacturer(
        manufactureId, manufactureName, address, phone, email, description  
    )  
    VALUES (  
        p_manufactureId, p_manufactureName, p_address, p_phone, p_email, p_description  
    );

    SELECT p_manufactureId ;
END
