我有一个名为region的表格定义
place_id | integer |
pts | point[] |
region_name | text |
region_id | integer | not null default nextval('region_region_id_seq'::regclass)
我希望能够从Python中插入一行。我有一个名为pgon的数组。
'{{-171.01155,-11.05869},{-171.01116,-11.06022},{-171.01138,-11.07814},{-171.01708,-11.08953},{-171.01963,-11.09463},{-171.03217,-11.10509},{-171.04886,-11.10929},{-171.07441,-11.11013},{-171.09834,-11.10787},{-171.10588,-11.10552},{-171.12063,-11.10091},{-171.13384,-11.09055},{-171.13385,-11.09055},{-171.13386,-11.09054},{-171.13387,-11.09053},{-171.13386,-11.09053},{-171.13384,-11.09053},{-171.13383,-11.09053},{-171.13529,-11.08719},{-171.13966,-11.07717},{-171.14112,-11.07383},{-171.14113,-11.07382},{-171.14114,-11.07382},{-171.14115,-11.07382},{-171.14191,-11.06076},{-171.14118,-11.04661},{-171.14116,-11.04622},{-171.13745,-11.03009},{-171.12577,-11.0156},{-171.1114,-11.00379},{-171.09488,-10.9978},{-171.08485,-10.9975},{-171.07463,-10.9972},{-171.05771,-10.99903},{-171.05163,-11.00014},{-171.03634,-11.00291},{-171.03358,-11.00409},{-171.0279,-11.00652},{-171.01928,-11.01225},{-171.01876,-11.01339},{-171.01407,-11.0237},{-171.01238,-11.04712}}'
place_id = 6,名称 =“美属萨摩亚” 我的Python命令行是:
cur.execute("insert into region (place_id,pts,region_name) values (%,%,%)",(place_id, pgon, name))
但是我收到了一个ValueError错误:"不支持的格式字符 ','(0x2c)在索引55处"
我以前做过插入操作,但没有在目标中使用point[]。有人能告诉我应该如何做吗?谢谢。
