MySQL 5.7.19 提供给函数的无效 GIS 数据 st_geometryfromtext

Question

所以我是 MySql 中 ST_ 函数的新手，我认为我遗漏了一些东西。我试图在 MySql 中保存多边形，问题是当使用函数 ST_GEOMFROMTEXT 并给出取自 Google 地图 Javascript [=25 的多边形坐标时=] 它 returns 错误：Invalid GIS data provided to function st_geometryfromtext.

我在网上看了很多，但到处都是说这是版本问题，这里是我现在有最新的 (5.7.19)

这些是我试过的以下查询

# WORKS
SELECT ST_GEOMFROMTEXT('POLYGON((13.517837674890684 76.453857421875,13.838079936422464 77.750244140625,14.517837674890684 79.453857421875,13.517837674890684 76.453857421875,13.517837674890684 76.453857421875))');

# ALL BELLOW RETURN ERROR

SELECT ST_GEOMFROMTEXT('POLYGON((-99.17182445526123 19.4254572621497, -99.16570901870728 19.42574056861496, -99.16558027267456 19.421551629818985, -99.17210340499878 19.421288552764135 ))');
SELECT ST_GEOMFROMTEXT('POLYGON((19.4249108840002 -99.17023658752441, 19.424951356518726 -99.16802644729614, 19.423393157277722 -99.16796207427979, 19.423393157277722 -99.17019367218018))')

有谁知道为什么上面的这些查询失败了？非常感谢大家

请尝试这些查询 -

SELECT ST_GEOMFROMTEXT('POLYGON((19.4254572621497 -99.17182445526123, 19.42574056861496 -99.16570901870728, 19.421551629818985 -99.16558027267456, 19.421288552764135 -99.17210340499878, 19.4254572621497 -99.17182445526123))');
SELECT ST_GEOMFROMTEXT('POLYGON((-99.17182445526123 19.4254572621497, -99.16570901870728 19.42574056861496, -99.16558027267456 19.421551629818985, -99.17210340499878 19.421288552764135, -99.17182445526123 19.4254572621497 ))');
SELECT ST_GEOMFROMTEXT('POLYGON((19.4249108840002 -99.17023658752441, 19.424951356518726 -99.16802644729614, 19.423393157277722 -99.16796207427979, 19.423393157277722 -99.17019367218018, 19.4249108840002 -99.17023658752441))')

基本上，多边形需要“闭合”
