我们试图使用Python将MultiLineString插入到PostgreSQL数据库中。我们正在使用ppygis
将我们的坐标转换为实际的几何图形。看台是要插入的坐标。该列表的格式如下:psycopg2.InternalError:解析错误 - 无效几何
[nº of points in line, x1line1, y1line1, ..., nº of points in line, ...]
当插入到数据库中,我们得到这个错误:如果我们改变ST_PointFromText到ST_GeomFromText
psycopg2.InternalError: parse error - invalid geometry
HINT: "0101000020e6100000645d" <-- parse error at position 22 within geometry
CONTEXT: SQL function "st_pointfromtext" statement 1
的错误是:
psycopg2.InternalError: parse error - invalid geometry
HINT: "0101000020e6100000645d" <-- parse error at position 22 within geometry
的ppygis python模块也严重缺乏文档,我们不知道哪个是错误。
任何帮助?谢谢。
