from provinces
 where ST_Contains(GeomFromText(CONCAT('POINT(',51.4, ' ', 37.2,')'),4326),polygon)

Answer 1

SELECT ea.entity_id,ea.latitude, ea.longitude ,c.name
from entity_addresses  as ea
inner join cities as c on  ST_CONTAINS(c.polygon, 
               ST_GeomFromText(ST_AsText(point(ea.longitude, ea.latitude)), 
4326))
