我需要翻译这个PostGIS查询:
SELECT boundary
ST_Intersects(ST_SetSRID(ST_Buffer(ST_MakePoint(11.255492,43.779251),0.002), 4326), ST_GeomFromKML(boundary)) as intersect,
FROM
mytable
WHERE
ST_Intersects(ST_SetSRID(ST_Buffer( ST_MakePoint(11.255492,43.779251),0.002), 4326), ST_GeomFromKML(boundary))
LIMIT 1
到带有空间数据的 MySQL。
我试过这个,但它不起作用:
SELECT
boundary,
ST_Intersects(Buffer('POINT(11.7094335,44.2754631)', 2), GeomFromText(boundary)) as intersect
FROM
mytable
WHERE
ST_Intersects(Buffer('POINT(11.7094335,44.2754631)', 2), GeomFromText(boundary))
MySQLboundary
列包含以下格式的数据:
POLYGON((11.752094222227 44.322710250414,11.753712975677 44.322710250414,11.753712975677 44.321900873689,11.752094222227 44.321900873689,11.752094222227 44.322710250414))
我做错了什么?
我通过尝试又一次找到了答案...... 这解决了问题:
SELECT
boundary,
ST_Intersects(GEOMFROMTEXT(boundary), ST_Buffer(POINT(11.752094222227, 44.322710250414), 2)) as intersect
FROM
mytable
WHERE
ST_Intersects(GEOMFROMTEXT(boundary), ST_Buffer(POINT(11.752094222227, 44.322710250414), 2))
我希望这对未来的用户有用。
