我有一個表,區域,定義插入點的數組於Postgres從蟒
place_id | integer |
pts | point[] |
region_name | text |
region_id | integer | not null default nextval('region_region_id_seq'::regclass)
和想從蟒插入一行。 我pgon

place_id = 6陣列,名稱= 「美國薩摩亞」 我的Python命令行是:
cur.execute("insert into region (place_id,pts,region_name) values (%,%,%)",(place_id, pgon, name))
,但我得到 ValueError異常:「不支持的格式字符」, '(0x2c)at index 55「
我已經做過插入,但沒有在目標中的點[]。有人能告訴我我該怎麼做嗎?謝謝。
按承諾工作。謝謝。一個問題,如果你然後嘗試cursor.fetchall()有一個異常:ValueError:'無法將字符串轉換爲浮點數:(-171.01155,-11.05869)' – LenB
