I am creating a procedure stored in MySQL to export tables with a dynamic route, but when I execute "CALL export_data ('data2018', 'e: Datos.csv')" I get an error, it seems that the path must be between 'quotes' but I have no idea how to put those quotes to the '?' so that it does not stop being variable, hopefully someone can help me solve this problem, thanks

DELIMITER $$
CREATE PROCEDURE export_data (name VARCHAR(25), path VARCHAR(50))
BEGIN
 SET @tableName = name;
 SET @pathName = path;
 SET @q = CONCAT('SELECT AP,AM,Nom,DNI,Direc INTO OUTFILE ? FIELDS 
 TERMINATED BY "," LINES TERMINATED BY "n" FROM `',@tableName,'` 
 ORDER BY AP ASC');
 PREPARE stmt FROM @q;
 EXECUTE stmt USING @pathName;
 DEALLOCATE PREPARE stmt;
END $$
DELIMITER;

I prefer to use ascii character 39 where single quotes are needed. And I don't see the need for user defined variables.

drop procedure if exists p;

DELIMITER $$
CREATE PROCEDURE p (name VARCHAR(25), path VARCHAR(50))
BEGIN
 SET @q = CONCAT('SELECT AP,AM,Nom,DNI,Direc INTO OUTFILE ',char(39),path,char(39),' FIELDS 
 TERMINATED BY "," LINES TERMINATED BY "n" FROM ' ,char(39),name,char(39),
 ' ORDER BY AP ASC');
 select @q;

 # PREPARE stmt from @q;
 # EXECUTE stmt ;
 # DEALLOCATE PREPARE stmt;
END $$
DELIMITER ;
