MySQL queries nearby data And sort by distance

Business background :

Check the public toilets near me , When querying, pass in the longitude of the current user (lng) And latitude (lat), Calculate the location with the toilet information in the database , Get the distance between me and each toilet ( Company : km ), And sort according to the distance , The most recent ones are displayed at the top

SELECT
    t1.name,
    t1.address,
    t1.uid,
    t1.code
    CONVERT(ACOS(COS(${lat}*PI()/180 )*COS(t1.lat*PI()/180)*COS(${lng}*PI()/180-t1.lng*PI()/180)+SIN(${lat}*PI()/180 )*SIN(t1.lat*PI()/180))*6370996.81/1000, DECIMAL(10,2)) AS distance    
FROM
    toilet t1
WHERE
    t1.is_delete = '0' 
ORDER BY 
    distance ASC

The result of the query :
