how to make multiple LIKE AND statements inside stored procedured? - mysql

Question

For example, I got an array :
carBrand: 'ford','volve','honda'
I would like to search a field which contained all elements of it, just like :
SELECT * FROM car_company WHERE car_company.brandStory LIKE '%ford%' AND car_company.brandStory LIKE '%volve%'
AND car_company.brandStory LIKE '%honda%';
And the array is an input parameter outside stored procedure
So far, I got two approachs nearly but still not good to me：
use REGEXP
for example:
SET carBrand = 'ford|volve|honda'; //input parameter
SELECT * FROM car_company WHERE car_company.brandStory REGEXP carBrand;
But the code make the OR statement actually, all I want is AND statement.
use full-text index
for example:
SET carBrand = '+ford +volve +honda'; //input parameter
SELECT * FROM car_company WHERE MATCH (brandStory) AGAINST (carBrand IN BOOLEAN MODE);
This is the closest solution I have found，but I really don't want to set the full-text index.
Is there any other solution ? Thanks everyone !

This stored procedure
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 ;
Would run with this call
call BuildSelect('Ford,Audi,Mercedes');
Run this query
SELECT * FROM car_company
WHERE car_company.brandStory LIKE '%Ford%'
AND car_company.brandStory LIKE '%Audi%'
AND car_company.brandStory LIKE '%Mercedes%';
