创建mysql自定义函数从txt文件导入数据

我想创建一个mysql函数，将数据从txt文件导入mysql表

以下是我迄今为止所做的工作：

打开创建新函数，将函数命名为load\u file\u txt 然后我添加了这些行

LOAD DATA INFILE `data_file.txt`
INTO TABLE `reservation_general`
FIELDS TERMINATED BY `,`
LINES TERMINATED BY `\n`

所以整个函数现在是这样的

DELIMITER $$

CREATE
    FUNCTION `customsearch`.`load_file_txt`()
    RETURNS TYPE
    BEGIN

LOAD DATA INFILE `data_file.txt`
INTO TABLE `reservation_general`
FIELDS TERMINATED BY `,`
LINES TERMINATED BY `\n`
    END$$

DELIMITER ;

Im使用SQL Yog并安装了mysql工作台。 下面是txt文件中的一些数据

在尝试运行上述函数后，我得到了这个错误

Query: CREATE FUNCTION `customsearch`.`load_file_txt`() RETURNS TYPE BEGIN LOAD DATA INFILE `data_file.txt` INTO TABLE `reservation_gen...

Error Code: 1064
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'TYPE
    BEGIN

我不知道为什么我会犯这个错误。希望有人能帮助我创建函数，从文件中读取数据并将其导入mysql表。

返回类型lookswrong@a_horse_with_no_name它已经写在那里了。@a_horse_和_no_name我删除了那行，但仍然得到了错误。函数需要返回一些东西，声明函数时不能只删除返回。请阅读手册。
