当我运行以下查询时,它没有返回任何内容。请帮我。在此先感谢。
SELECT *
FROM geomit
WHERE MBRContains(LineFromText(CONCAT(
'('
, 1.330690209415938 + 10 / ( 111.1 / cos(RADIANS(1.330690209415938)))

注意:我的创建表脚本是:
CREATE TABLE geomit (
latitude double,
longitude double,
latlong GEOMETRY NOT NULL,
SPATIAL INDEX(latlong)) ENGINE=MyISAM;
答案 0 :(得分:0)
是否写入比较线(不是多边形)和点?
也许你需要从这两个点加上另外两个点构建一个矩形而不是一条线?
