SQL存储过程字符串通过传递参数搜索并使用"LIKE"查询

Question

我正在尝试创建一个存储过程,它将使用用户在调用SP时传递的参数来搜索我的表.我想使用'LIKE'查询.到目前为止,这就是我得到的.

DROP PROCEDURE IF EXISTS `SEARCH_STUDENT`$$
CREATE
    PROCEDURE `test`.`SEARCH_STUDENT`(_textInput VARCHAR(10))
    BEGIN

    SELECT * FROM records WHERE `lastname` LIKE '%'+_textInput+'%';
    END$$

但我得到这个错误:

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 '@Search varchar(10);
    SET @Search=_textInput;
    SELECT * FROM records WHERE `last' at line 10

我从谷歌获得的是带有固定字符串的样本.我的取决于用户将在文本框中输入的内容.非常感谢您提供的任何帮助.

sql CONCAT函数就是答案.这是我现在的代码:

CREATE
    PROCEDURE `test`.`SEARCH_STUDENT`(_textInput VARCHAR(10))
    BEGIN

    -- sELECT * FROM records WHERE `lastname` LIKE '%' + _textInput;
    SELECT * FROM records WHERE `lastname` LIKE CONCAT('%',_textInput,'%');

    END$$
