用于Geometry包的MySQL字符串编码

我正在努力解决编码问题

我有一个MySQL表，在“多边形”列中包含坐标列表。多边形都是不相交的。我想使用ST_Contains（）函数来查找哪个多边形是点。这是我的SQL查询（x和y是双精度的）：

当我尝试此查询时，服务器响应一条错误消息：

ERROR 3055 (HY000): Geometry byte string must be little endian.

经过一些搜索后，我用以下内容修改了列的字符集：

ALTER TABLE polygones MODIFY polygone mediumtext CHARACTER SET utf16le;

但我仍然有同样的错误。我没有主意了/

如果您需要更多信息，请不要犹豫

注意：我在下面粘贴了一个多边形条目的示例：

46.120052 4.926273,46.120692 4.921995,46.126637 4.921996,46.129165 4.909363,46.135851 4.909232,46.144537 4.91604,46.157977 4.903081,46.160961 4.904571,46.180433 4.910603,46.182715 4.914132,46.183046 4.932896,46.173769 4.938714,46.164259 4.932778,46.153246 4.958286,46.145964 4.943331,46.12938 4.939155,46.120871 4.931056,46.120052 4.926273

列的类型应为“多边形”或“几何体”。如果由于任何原因无法执行此操作，请使用此函数：ST_GeomFromText（polygon）
