如何在存储过程中创建多个 LIKE AND 语句？

Question

例如，我有一个数组：

汽车品牌：“福特”、“沃尔夫”、“本田”

我想搜索一个包含所有元素的字段，就像：

SELECT * FROM car_company WHERE car_company.brandStory LIKE '%ford%' AND car_company.brandStory LIKE '%volve%' 
AND car_company.brandStory LIKE '%honda%';

并且数组是存储过程之外的输入参数

到目前为止，我几乎得到了两种方法，但对我来说仍然不好：

1. 使用正则表达式

例如：

SET carBrand = 'ford|volve|honda'; //input parameter
SELECT * FROM car_company WHERE car_company.brandStory REGEXP carBrand;

但代码实际上是 OR 语句，我想要的只是 AND 语句。

1. 使用全文索引

例如：

SET carBrand = '+ford +volve +honda';  //input parameter
SELECT * FROM car_company WHERE MATCH (brandStory) AGAINST (carBrand IN BOOLEAN MODE);

这是我找到的最接近的解决方案，但我真的不想设置全文索引。

还有其他解决方案吗？谢谢大家！

这个存储过程

USE `testdb`;
DROP procedure IF EXISTS `BuildSelect`;

DELIMITER $$
USE `testdb`$$
CREATE DEFINER=`root`@`localhost` PROCEDURE `BuildSelect`(IN carbrand TEXT)
BEGIN

    DECLARE brand TEXT DEFAULT NULL;
    DECLARE brandlength INT DEFAULT 0;
    DECLARE Tempbrand TEXT DEFAULT NULL;



    SET @Selectstr = "SELECT * FROM car_company WHERE";
    iterator:
    LOOP
        IF LENGTH(TRIM(carbrand)) = 0 OR carbrand IS NULL THEN
            LEAVE iterator;
        END IF;
        SET brand = SUBSTRING_INDEX(carbrand,',',1);
        SET Tempbrand = CONCAT(" car_company.brandStory LIKE '%",TRIM(brand),"%'");
        IF brandlength > 0 THEN
            SET Tempbrand = CONCAT(" AND",Tempbrand);
        END IF;
        SET @Selectstr = CONCAT(@Selectstr,COALESCE(Tempbrand,''));
        SET carbrand = SUBSTRING_INDEX(carbrand,',',-(LENGTH(carbrand) - LENGTH(REPLACE(carbrand, ',', '')) ));
        SET brandlength = brandlength +1;
    END LOOP iterator;
    SET @Selectstr = CONCAT(@Selectstr ,";");
    PREPARE  id  FROM @Selectstr;
    EXECUTE id;
    DEALLOCATE PREPARE id;
    #SELECT @Selectstr;
END$$

DELIMITER ;

将与此调用一起运行

 call BuildSelect('Ford,Audi,Mercedes');

运行此查询

SELECT * FROM car_company 
WHERE car_company.brandStory LIKE '%Ford%' 
      AND car_company.brandStory LIKE '%Audi%' 
      AND car_company.brandStory LIKE '%Mercedes%';
