Hello! Tell me please, where do I make a mistake? There are coordinates 
And there is a request
SELECT ST_Y(coord_point) as lat, ST_X(coord_point) as lng FROM `customer` WHERE ST_Contains(ST_GEOMFROMTEXT('POLYGON((54.17489482345622 26.503829956054688, 54.375358319198526 26.503829956054688, 54.375358319198526 27.286605834960938, 54.17489482345622 27.286605834960938, 54.17489482345622 26.503829956054688))'), coord_point); It seems that the polygon is "closed" and all the points are in it, but they are not displayed. I would be grateful if you tell me where to dig ...
