Creating CSV file with current day mysql

Question

How can a export data from mysql to a file csv with the date and hour of the day. I try this code but I get a error

SELECT *
FROM order
INTO OUTFILE '/tmp/',NOW(),'_orders.csv'
FIELDS TERMINATED BY ','
ENCLOSED BY '"'
LINES TERMINATED BY '\n';

here my error

1064 - 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 '"' ,NOW(), '"'_orders.csv' FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TER' at line 3

this is my event work great but im want diferent cvs in every end of the month

CREATE DEFINER = `admin`@`localhost` EVENT `Order` 
ON SCHEDULE EVERY1 MONTH STARTS '2018-12-01 00:00:00' 
ON COMPLETION NOT PRESERVE ENABLE 
COMMENT 'Order save' 
DO SELECT *
FROM Order
INTO OUTFILE '/tmp/_orders.csv'

Here the query getting the name with the date but I cant add this one in the event

SET @`outfull` := CONCAT('/tmp/', NOW(), 'orders.csv');
SET @`qry` := CONCAT('SELECT * 
                        INTO OUTFILE \'', @`outfull`, '\' 
                        FIELDS TERMINATED BY \';\' 
                        ENCLOSED BY \'"\' 
                        LINES TERMINATED BY \'\n\' 
                      FROM `order`');

PREPARE `stmt` FROM @`qry`;
SET @`qry` := NULL;
EXECUTE `stmt`;
DEALLOCATE PREPARE `stmt`;

Try prepared statement :

set @sql = concat('SELECT *
FROM tradooITLangues 
INTO OUTFILE ', concat('\'', '/tmp/', NOW(), '_orders.csv', '\''),
' FIELDS TERMINATED BY \',\'
ENCLOSED BY \'"\'
LINES TERMINATED BY \'#\n\';');

PREPARE stmt1 FROM @sql;
EXECUTE stmt1; 
DEALLOCATE PREPARE stmt1; 

In an event (my MySQL accepted the syntax) :

delimiter $$
CREATE DEFINER = `admin`@`localhost` EVENT `Order` 
ON SCHEDULE EVERY 1 MONTH STARTS '2018-12-01 00:00:00' 
ON COMPLETION NOT PRESERVE ENABLE 
COMMENT 'Order save' 
DO
BEGIN

    SET @`outfull` := CONCAT('/tmp/', NOW(), 'orders.csv');
    SET @`qry` := CONCAT('SELECT * 
                            INTO OUTFILE \'', @`outfull`, '\' 
                            FIELDS TERMINATED BY \';\' 
                            ENCLOSED BY \'"\' 
                            LINES TERMINATED BY \'\n\' 
                          FROM `order`');

    PREPARE `stmt` FROM @`qry`;
    SET @`qry` := NULL;
    EXECUTE `stmt`;
    DEALLOCATE PREPARE `stmt`;

END;
