MySQL5.6中查询多边形包含点情况（ST_Contains、ST_Within）

SET @x = 121;
SET @y = 30;  
-- SET @point = CONCAT(‘POINT(‘,@x,‘ ‘,@y,‘)‘); 
set @point= Point(@x,@y);
set @geometry=ST_GeomFromText(‘POLYGON((121.044 30.594, 121.046 30.59, ..., 121.046 30.5948, 121.044 30.594))‘);
SELECT ST_Contains(@geometry,@point);//面包含点
SELECT ST_Within(@point, @geometry);//点在面
