Question

具有POINT数据类型的数据库表。我无法从MySQL POLYGON查询中获得任何结果。知道我做错了什么吗？多边形已关闭。

id  location
1   POINT(-37.816652 144.964595)    
2   POINT(-37.788132 144.931183)
3   POINT(-37.811291 144.985916)

SELECT * FROM `properties` WHERE Contains (GeomFromText('POLYGON((145.45740074179685, -37.711586434367305, 144.6142000582031, -37.711586434367305, 144.6142000582031, -37.92854972934211, 145.45740074179685, -37.92854972934211, 145.45740074179685, -37.711586434367305))'), location)

SELECT * FROM `properties` WHERE Contains (PolygonFromText('POLYGON((145.45740074179685, -37.711586434367305, 144.6142000582031, -37.711586434367305, 144.6142000582031, -37.92854972934211, 145.45740074179685, -37.92854972934211, 145.45740074179685, -37.711586434367305))'), location)

Answer 1

你好像让你的坐在错误的顺序。

GeomFromText('POLYGON((-37.711586434367305,145.45740074179685,
  -37.711586434367305, 144.6142000582031,  ....)))

此外，不推荐使用Contains。最好使用MBRContains。

MySQL POLYGON查询没有结果
