MySQL POLYGON查詢無結果

Question

帶有POINT數據類型的數據庫表。我無法從MySQL POLYGON查詢中得到任何結果。任何想法我做錯了什麼？多邊形是封閉的。

id location 
1 POINT(-37.816652 144.964595)  
2 POINT(-37.788132 144.931183) 
3 POINT(-37.811291 144.985916) 
4 POINT(-37.8389571 144.9656531000001) 
5 POINT(-37.851038 144.993205) 
6 POINT(-37.8029679 144.9501126)

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

你似乎已經得到了你的cordinates在錯誤的順序。

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

另外Contains已被棄用。更好地使用MBRContains。
