SET DATESTYLE TO 'European'; in MySQL I'm doing MySQL exercises and I found some of PostgreSQL, and there is a part where before entering the data to the newly created tables, enter that command, SET DATESTYLE TO 'European'; I tried to put it in MySQL but it does not recognize it, what would be its equivalent?
mysql store all the dates in the same style. Internally this is three bytes that are expanded to the YYYY-MM-DD. You can convert this format to the any desired form by DATE_FORMAT() function like that: 

SELECT DATE(now()) AS sysformat
     , DATE_FORMAT( NOW(), '%W %M %D %Y, %j\'th day of the year') AS myformat
