I did one like so that helped me prepare a dynamic section in my where clause:

DELIMITER $$;

DROP FUNCTION IF EXISTS `apache_logs`.`split`$$

CREATE DEFINER=`User`@`localhost` FUNCTION `split`(sStringIn text,splitChar varchar(1)) RETURNS text CHARSET latin1
NO SQL
BEGIN
DECLARE comma INT DEFAULT 0;
DECLARE mylist TEXT DEFAULT sStringIn;
DECLARE temp TEXT DEFAULT '';
DECLARE strlen int DEFAULT LENGTH(sStringIn);
DECLARE outtext text(10000) DEFAULT '';

/* find the first instance of the spliting character */
SET comma = LOCATE(splitChar,mylist);
/* Insert each split variable into the temp table */
set outtext='';
WHILE strlen > 0 DO
IF comma = 0 THEN
SET temp = TRIM(mylist);
SET mylist = '';
SET strlen = 0;
END IF;
IF comma != 0 THEN
SET temp = TRIM(SUBSTRING(mylist,1,comma-1));
SET mylist = TRIM(SUBSTRING(mylist FROM comma+1));
SET strlen = LENGTH(mylist);
END IF;

IF temp != ''
THEN
/* This is the magic line and can be converted to whatever you need */
set outtext = concat(outtext,' and Path not like ',char(39),char(37),temp,char(37),char(39));
END IF;
SET comma = LOCATE(splitChar,mylist);
END WHILE;

return outtext;
END$$

DELIMITER ;$$
