查詢MySQL幾何數據類型列中的數據

我有一個表格，它在使用ogr2ogr通過shapefile加載的GEOMETRY數據類型列中存儲多邊形。下面是create語句：查詢MySQL幾何數據類型列中的數據

CREATE TABLE IF NOT EXISTS `sunzones` (
    `OGR_FID` int(11) NOT NULL AUTO_INCREMENT, 
    `polygon` geometry NOT NULL, 
    UNIQUE KEY `OGR_FID` (`OGR_FID`), 
    SPATIAL KEY `polygon` (`polygon`) 
) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=105 ;

下面是一個簡單的記錄：

，其使用查詢：

我有一個特定的緯度和經度，我想要知道哪些記錄具有包含該lat/lng的多邊形，所以我試過這個查詢：

SELECT * FROM sunzones WHERE MBRWithin(GeomFromText('Point(21.3069 -157.8583)'), polygon);

但不返回記錄。我甚至嘗試將lat/lng轉換爲UTM座標，但是此查詢也返回沒有記錄：

SELECT * FROM sunzones WHERE MBRWithin(GeomFromText('Point(2447696.15327556 447233.893916706)'), polygon);

我的查詢有什麼問題嗎？順便說一下，我使用的是MySQL 5.6。另外，我也試過了ST_CONTAINS（）和CONTAINS（）。

請注意，查詢中的座標不一定落在我上面發佈的單個樣本多邊形的內部。形狀都在夏威夷，所以我的經緯度就是檀香山的座標。

花費了太多的時間與此搗亂，我想出了查詢正確的語法：

SELECT * FROM sunzones WHERE MBRWITHIN(POINT(863575.082797506, 2137306.79465704) , polygon)

重要的事情，這裏要注意的是，座標反轉（經度/緯度，而不是緯度/經度），並且與大多數發佈的例子不同，我不必使用GeomFromText（）來聲明Point。
