我們試圖使用Python將MultiLineString插入到PostgreSQL數據庫中。我們正在使用ppygis
將我們的座標轉換爲實際的幾何圖形。看臺是要插入的座標。該列表的格式如下:psycopg2.InternalError:解析錯誤 - 無效幾何
[nº of points in line, x1line1, y1line1, ..., nº of points in line, ...]
當插入到數據庫中,我們得到這個錯誤:如果我們改變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
的錯誤是:
psycopg2.InternalError: parse error - invalid geometry
HINT: "0101000020e6100000645d" <-- parse error at position 22 within geometry
的ppygis python模塊也嚴重缺乏文檔,我們不知道哪個是錯誤。
任何幫助?謝謝。
